Aides auditives ; Fatigue ; PERTE AUDITIVE DE PERCEPTIONRésumé : AB Objectives: To conduct a systematic review to address two research questions: (Q1) Does hearing loss have an effect on fatigue? (Q2) Does hearing device fitting have an effect on fatigue? It was hypothesized that hearing loss would increase fatigue (H1), and hearing device fitting would reduce fatigue (H2). Design: Systematic searches were undertaken of five bibliographic databases: Embase, MedLine, Web of Science, Psychinfo, and the Cochrane Library. English language peer-reviewed research articles were included from inception until present. Inclusion and exclusion criteria were formulated using the Population, Intervention, Comparison, Outcomes and Study design strategy. Results: Initial searches for both research questions produced 1,227 unique articles, after removal of duplicates. After screening, the full text of 61 studies was checked, resulting in 12 articles with content relevant to the research questions. The reference lists of these studies were examined, and a final updated search was conducted on October 16, 2019. This resulted in a final total of 20 studies being selected for the review. For each study, the information relating to the Population, Intervention, Comparison, Outcomes and Study design criteria and the statistical outcomes relating to both questions (Q1 and Q2) were extracted. Evidence relating to Q1 was provided by 15 studies, reporting 24 findings. Evidence relating to Q2 was provided by six studies, reporting eight findings. One study provided evidence for both. Using the Grading of Recommendations Assessment, Development and Evaluation guidelines, the quality of evidence on both research questions was deemed to be "very low." It was impossible to perform a meta-analysis of the results due to a lack of homogeneity. Conclusions: As the studies were too heterogeneous to support a meta-analysis, it was not possible to provide statistically significant evidence to support the hypotheses that hearing loss results in increased fatigue (H1) or that hearing device fitting results in decreased fatigue (H2). Despite this, the comparative volume of positive results and the lack of any negative findings are promising for future research (particularly in respect of Q1). There was a very small number of studies deemed eligible for the review, and there was large variability between studies in terms of population, and quantification of hearing loss and fatigue. The review highlights the need for consistency when measuring fatigue, particularly when using self-report questionnaires, where the majority of the current evidence was generated.

Cortex prefrontal dorso-lateralRésumé : AB Objectives: Tinnitus is the perception of sound in ears or head without corresponding external stimulus. Despite the great amount of literature concerning tinnitus treatment, there are still no evidence-based established treatments for curing or for effectively reducing tinnitus intensity. Sham-controlled studies revealed beneficial effects using repetitive transcranial magnetic stimulation (rTMS). Still, results show moderate, temporary improvement and high individual variability. Subcallosal area (ventral and dorsomedial prefrontal and anterior cingulate cortices) has been implicated in tinnitus pathophysiology. Our objective is to evaluate the use of bilateral, high frequency, dorsomedial prefrontal cortex (DMPFC) rTMS in treatment of chronic subjective tinnitus. Design: Randomized placebo-controlled, single-blinded clinical trial. Twenty sessions of bilateral, 10 Hz rTMS at 120% of resting motor threshold of extensor hallucis longus were applied over the DMPFC. Fourteen patients underwent sham rTMS and 15 were submitted to active stimulation. Tinnitus Handicap Inventory (THI), visual analog scale, and tinnitus loudness matching were obtained at baseline and on follow-up visits. The impact of intervention on outcome measures was evaluated using mixed-effects restricted maximum likelihood regression model for longitudinal data. Results: A difference of 11.53 points in the THI score was found, favoring the intervention group (p = 0.05). The difference for tinnitus loudness matching was of 4.46 dB also favoring the intervention group (p = 0.09). Conclusions: Tinnitus treatment with high frequency, bilateral, DMPFC rTMS was effective in reducing tinnitus severity measured by THI and matched tinnitus loudness when compared to sham stimulation.

Confinement ; COVID-19 ; Déficience auditive ; Isolement socialRésumé : AB Objectives: The impact of social distancing on communication and psychosocial variables among individuals with hearing impairment during COVID-19 pandemic. It was our concern that patients who already found themselves socially isolated ( Wie et al. 2010) as a result of their hearing loss would be perhaps more susceptible to changes in their communication habits resulting in further social isolation, anxiety, and depression. We wanted to better understand how forced social isolation (as part of COVID-19 mitigation) effected a group of individuals with hearing impairment from an auditory ecology and psychosocial perspective. We hypothesized that the listening environments would be different as a result of social isolation when comparing subject's responses regarding activities and participation before COVID-19 and during the COVID-19 pandemic. This change would lead to an increase in experienced and perceived social isolation, anxiety, and depression. Design: A total of 48 adults with at least 12 months of cochlear implant (CI) experience reported their listening contexts and experiences pre-COVID and during-COVID using Ecological Momentary Assessment (EMA; methodology collecting a respondent's self-reports in their natural environments) through a smartphone-based app, and six paper and pencil questionnaires. The Smartphone app and paper-pencil questionnaires address topics related to their listening environment, social isolation, depression, anxiety, lifestyle and demand, loneliness, and satisfaction with amplification. Data from these two-time points were compared to better understand the effects of social distancing on the CI recipients' communication abilities. Results: EMA demonstrated that during-COVID CI recipients were more likely to stay home or be outdoors. CI recipients reported that they were less likely to stay indoors outside of their home relative to the pre-COVID condition. Social distancing also had a significant effect on the overall signal-to-noise ratio of the environments indicating that the listening environments had better signal-to-noise ratios. CI recipients also reported better speech understanding, less listening effort, less activity limitation due to hearing loss, less social isolation due to hearing loss, and less anxiety due to hearing loss. Retrospective questionnaires indicated that social distancing had a significant effect on the social network size, participant's personal image of themselves, and overall loneliness. Conclusions: Overall, EMA provided us with a glimpse of the effect that forced social isolation has had on the listening environments and psychosocial perspectives of a select number of CI listeners. CI participants in this study reported that they were spending more time at home in a quieter environments during-COVID. Contrary to our hypothesis, CI recipients overall felt less socially isolated and reported less anxiety resulting from their hearing difficulties during-COVID in comparison to pre-COVID. This, perhaps, implies that having a more controlled environment with fewer speakers provided a more relaxing listening experience.

Audiométrie haute fréquence (EHF) ; Déficience auditive ; Emissions otoacoustiques spontanées (OAEs) ; Wideband absorbance (WBA)Résumé : AB Objectives: This study tested the hypothesis that undetected peripheral hearing impairment occurs in children with idiopathic listening difficulties (LiDs), as reported by caregivers using the Evaluation of Children"s Listening and Processing Skills (ECLiPS) validated questionnaire, compared with children with typically developed (TD) listening abilities. Design: Children with LiD aged 6-14 years old (n = 60, mean age = 9.9 yr) and 54 typical age matched children were recruited from audiology clinical records and from IRB-approved advertisements at hospital locations and in the local and regional areas. Both groups completed standard and extended high-frequency (EHF) pure-tone audiometry, wideband absorbance tympanometry and middle ear muscle reflexes, distortion product and chirp transient evoked otoacoustic emissions. Univariate and multivariate mixed models and multiple regression analysis were used to examine group differences and continuous performance, as well as the influence of demographic factors and pressure equalization (PE) tube history. Results: There were no significant group differences between the LiD and TD groups for any of the auditory measures tested. However, analyses across all children showed that EHF hearing thresholds, wideband tympanometry, contralateral middle ear muscle reflexes, distortion product, and transient-evoked otoacoustic emissions were related to a history of PE tube surgery. The physiologic measures were also associated with EHF hearing loss, secondary to PE tube history. Conclusions: Overall, the results of this study in a sample of children with validated LiD compared with a TD group matched for age and sex showed no significant differences in peripheral function using highly sensitive auditory measures. Histories of PE tube surgery were significantly related to EHF hearing and to a range of physiologic measures in the combined sample.

Effet de cohorte ; Perte d'audition ; Prévalence ; Sujet âgéMots-clés : ISO 7029 Résumé : Objective: To obtain updated robust data on a age-specific prevalence of hearing loss in Norway and determine whether more recent birth cohorts have better hearing compared with earlier birth cohorts.
Design: Cross-sectional analyzes of Norwegian representative demographic and audiometric data from the Nord-Trondelag Health Study (HUNT)-HUNT2 Hearing (1996-1998) and HUNT4 Hearing (2017-2019), with the following distribution: HUNT2 Hearing (N=50,277, 53% women, aged 20 to 101 years, mean = 50.1, standard deviation = 16.9); HUNT4 Hearing (N=28,339, 56% women, aged 19 to 100 years, mean = 53.2, standard deviation = 16.9). Pure-tone hearing thresholds were estimated using linear and quantile regressions with age and cohort as explanatory variables. Prevalences were estimated using logistic regression models for different severities of hearing loss averaged over 0.5, 1, 2, and 4 kHz in the better ear (BE PTA4). We also estimated prevalences at the population-level of Norway in 1997 and 2018.
Results: Disabling hearing loss (BE PTA4 >= 35 dB) was less prevalent in the more recent born cohort at all ages in both men and women (p Conclusions: The age- and sex-specific prevalence of hearing impairment has decreased in Norway from 1996-1998 to 2017-2019DOI : 10.1097/AUD.0000000000000898|1 Disponible en ligne : Non En ligne : https://login.ezproxy.vinci.be/login?url=http://ovidsp.ovid.com/ovidweb.cgi?T=JS [...] Permalink : https://bib.vinci.be/opac_css/index.php?lvl=notice_display&id=263554

Titre : Search for Electrophysiological Indices of Hidden Hearing Loss in Humans: Click Auditory Brainstem Response Across Sound Levels and in Background Noise Type de document : Article Auteurs : Chandan Suresh ; Ananthanarayan Krishnan Année de publication : 2021 Article en page(s) : p. 53-67 Langues : Anglais (eng) Descripteurs : HE Vinci
Perte auditive cachée ; Potentiels évoqués auditifs du tronc cérébral (ABR) ; synaptopathie cochléaireRésumé : Objectives: Recent studies in animals indicate that even moderate levels of exposure to noise can damage synaptic ribbons between the inner hair cells and auditory nerve fibers without affecting audiometric thresholds, giving rise to the use of the term "hidden hearing loss" (HHL). Despite evidence across several animal species, there is little consistent evidence for HHL in humans. The aim of the study is to evaluate potential electrophysiological changes specific to individuals at risk for HHL.
Design: Participants forming the high-risk experimental group consisted of 28 young normal-hearing adults who participated in marching band for at least 5 years. Twenty-eight age-matched normal-hearing adults who were not part of the marching band and had little or no history of recreational or occupational exposure to loud sounds formed the low-risk control group. Measurements included pure tone audiometry of conventional and high frequencies, distortion product otoacoustic emissions, and electrophysiological measures of auditory nerve and brainstem function as reflected in the click-evoked auditory brainstem response (ABR). In experiment 1, ABRs were recorded in a quiet background across stimulus levels (30-90 dB nHL) presented in 10 dB steps. In experiment 2, the ABR was elicited by a 70 dB nHL click stimulus presented in a quiet background, and in the presence of simultaneous ipsilateral continuous broadband noise presented at 50, 60, and 70 dB SPL using an insert earphone (Etymotic, ER2).
Results: There were no differences between the low- and high-risk groups in audiometric thresholds or distortion product otoacoustic emission amplitude. Experiment 1 demonstrated smaller wave-I amplitudes at moderate and high sound levels for high-risk compared to low-risk group with similar wave III and wave V amplitude. Enhanced amplitude ratio V/I, particularly at moderate sound level (60 dB nHL), suggesting central compensation for reduced input from the periphery for high-risk group. The results of experiment 2 show that the decrease in wave I amplitude with increasing background noise level was relatively smaller for the high-risk compared to the low-risk group. However, wave V amplitude reduction was essentially similar for both groups. These results suggest that masking induced wave I amplitude reduction is smaller in individuals at high risk for cochlear synaptopathy. Unlike previous studies, we did not observe a difference in the noise-induced wave V latency shift between low- and high-risk groups.
Conclusions: Results of experiment 1 are consistent with findings in both animal studies (that suggest cochlear synaptopathy involving selective damage of low-spontaneous rate and medium-spontaneous rate fibers), and in several human studies that show changes in a range of ABR metrics that suggest the presence of cochlear synaptopathy. However, without postmortem examination by harvesting human temporal bone (the gold standard for identifying synaptopathy) with different noise exposure background, no direct inferences can be derived for the presence/extent of cochlear synaptopathy in high-risk group with high sound over-exposure history. Results of experiment 2 demonstrate that to the extent response amplitude reflects both the number of neural elements responding and the neural synchrony of the responding elements, the relatively smaller change in response amplitude for the high-risk group would suggest a reduced susceptibility to masking. One plausible mechanism would be that suppressive effects that kick in at moderate to high levels are different in these two groups, particularly at moderate levels of the masking noise. Altogether, a larger scale dataset with different noise exposure background, longitudinal measurements (changes due to recreational over-exposure by studying middle-school to high-school students enrolled in marching band) with an array of behavioral and electrophysiological tests are needed to understand the complex pathogenesis of sound over-exposure damage in normal-hearing individuals.Disponible en ligne : Oui En ligne : https://login.ezproxy.vinci.be/login?url=http://ovidsp.ovid.com/ovidweb.cgi?T=JS [...] Permalink : https://bib.vinci.be/opac_css/index.php?lvl=notice_display&id=263555

Titre : Vestibular Function in Children With a Congenital Cytomegalovirus Infection: 3 Years of Follow-Up Type de document : Article Auteurs : Cleo Dhondt ; Leen Maes ; Lotte Rombaut ; Sarie Martens ; Saartje Vanaudenaerde ; Helen Van Hoecke ; Els De Leenheer ; Ingeborg Dhooge Année de publication : 2021 Article en page(s) : p. 76-86 Langues : Anglais (eng) Descripteurs : HE Vinci
Audiologie pédiatrique ; Cytomegalovirus ; VestibulométrieRésumé : Objectives: Congenital cytomegalovirus (cCMV) infection is the most common nongenetic cause of sensorineural hearing loss in children. Due to the close anatomical relationship between the auditory and the vestibular sensory organs, cCMV can also be an important cause of vestibular loss. However, the prevalence and nature of cCMV-induced vestibular impairment is still underexplored. The aim of this study was to investigate the occurrence and characteristics of vestibular loss in a large group of cCMV-infected children, representative of the overall cCMV-population.
Design: Ninety-three children (41 boys, 52 girls) with a confirmed diagnosis of cCMV were enrolled in this prospective longitudinal study. They were born at the Ghent University Hospital or referred from another hospital for multidisciplinary follow-up in the context of cCMV. The test protocol consisted of regular vestibular follow-up around the ages of 6 months, 1 year, 2 years, and 3 years with the video Head Impulse Test, the rotatory test, and the cervical Vestibular Evoked Myogenic Potential test.
Results: On average, the 93 patients (52 asymptomatic, 41 symptomatic) were followed for 10.2 months (SD: 10.1 mo) and had 2.2 examinations (SD: 1.1). Seventeen (18%) patients had sensorineural hearing loss (7 unilateral, 10 bilateral). Vestibular loss was detected in 13 (14%) patients (7 unilateral, 6 bilateral). There was a significant association between the occurrence of hearing loss and the presence of vestibular loss (p
Conclusions: cCMV can impair not only the auditory but also the vestibular function. Similar to the hearing loss, vestibular loss in cCMV can be highly variable. It can be unilateral or bilateral, limited or extensive, stable or progressive, and early or delayed in onset. As the vestibular function can deteriorate over time and even normal-hearing subjects can be affected, vestibular evaluation should be part of the standard otolaryngology follow-up in all children with cCMV.DOI : 10.1097/AUD.0000000000000904|1 Disponible en ligne : Oui En ligne : https://login.ezproxy.vinci.be/login?url=http://ovidsp.ovid.com/ovidweb.cgi?T=JS [...] Permalink : https://bib.vinci.be/opac_css/index.php?lvl=notice_display&id=263562

Titre : Human Frequency Following Responses to Filtered Speech Type de document : Article Auteurs : Saradha Ananthakrishnan ; Laura Grinstead ; Danielle Yurjevich Année de publication : 2021 Article en page(s) : p. 87-105 Langues : Anglais (eng) Descripteurs : Autres descripteurs
Filtre auditif ; Frequence fondamentale (FO)Résumé : Objectives: There is increasing interest in using the frequency following response (FFR) to describe the effects of varying different aspects of hearing aid signal processing on brainstem neural representation of speech. To this end, recent studies have examined the effects of filtering on brainstem neural representation of the speech fundamental frequency (f0) in listeners with normal hearing sensitivity by measuring FFRs to low- and high-pass filtered signals. However, the stimuli used in these studies do not reflect the entire range of typical cutoff frequencies used in frequency-specific gain adjustments during hearing aid fitting. Further, there has been limited discussion on the effect of filtering on brainstem neural representation of formant-related harmonics. Here, the effects of filtering on brainstem neural representation of speech fundamental frequency (f0) and harmonics related to first formant frequency (F1) were assessed by recording envelope and spectral FFRs to a vowel low-, high-, and band-pass filtered at cutoff frequencies ranging from 0.125 to 8 kHz.
Design: FFRs were measured to a synthetically generated vowel stimulus /u/ presented in a full bandwidth and low-pass (experiment 1), high-pass (experiment 2), and band-pass (experiment 3) filtered conditions. In experiment 1, FFRs were measured to a synthetically generated vowel stimulus /u/ presented in a full bandwidth condition as well as 11 low-pass filtered conditions (low-pass cutoff frequencies: 0.125, 0.25, 0.5, 0.75, 1, 1.5, 2, 3, 4, 6, and 8 kHz) in 19 adult listeners with normal hearing sensitivity. In experiment 2, FFRs were measured to the same synthetically generated vowel stimulus /u/ presented in a full bandwidth condition as well as 10 high-pass filtered conditions (high-pass cutoff frequencies: 0.125, 0.25, 0.5, 0.75, 1, 1.5, 2, 3, 4, and 6 kHz) in 7 adult listeners with normal hearing sensitivity. In experiment 3, in addition to the full bandwidth condition, FFRs were measured to vowel /u/ low-pass filtered at 2 kHz, band-pass filtered between 2-4 kHz and 4-6 kHz in 10 adult listeners with normal hearing sensitivity. A Fast Fourier Transform analysis was conducted to measure the strength of f0 and the F1-related harmonic relative to the noise floor in the brainstem neural responses obtained to the full bandwidth and filtered stimulus conditions.
Results: Brainstem neural representation of f0 was reduced when the low-pass filter cutoff frequency was between 0.25 and 0.5 kHz; no differences in f0 strength were noted between conditions when the low-pass filter cutoff condition was at or greater than 0.75 kHz. While envelope FFR f0 strength was reduced when the stimulus was high-pass filtered at 6 kHz, there was no effect of high-pass filtering on brainstem neural representation of f0 when the high-pass filter cutoff frequency ranged from 0.125 to 4 kHz. There was a weakly significant global effect of band-pass filtering on brainstem neural phase-locking to f0. A trends analysis indicated that mean f0 magnitude in the brainstem neural response was greater when the stimulus was band-pass filtered between 2 and 4 kHz as compared to when the stimulus was band-pass filtered between 4 and 6 kHz, low-pass filtered at 2 kHz or presented in the full bandwidth condition. Last, neural phase-locking to f0 was reduced or absent in envelope FFRs measured to filtered stimuli that lacked spectral energy above 0.125 kHz or below 6 kHz. Similarly, little to no energy was seen at F1 in spectral FFRs obtained to low-, high-, or band-pass filtered stimuli that did not contain energy in the F1 region. For stimulus conditions that contained energy at F1, the strength of the peak at F1 in the spectral FFR varied little with low-, high-, or band-pass filtering.
Conclusions: Energy at f0 in envelope FFRs may arise due to neural phase-locking to low-, mid-, or high-frequency stimulus components, provided the stimulus envelope is modulated by at least two interacting harmonics. Stronger neural responses at f0 are measured when filtering results in stimulus bandwidths that preserve stimulus energy at F1 and F2. In addition, results suggest that unresolved harmonics may favorably influence f0 strength in the neural response. Lastly, brainstem neural representation of the F1-related harmonic measured in spectral FFRs obtained to filtered stimuli is related to the presence or absence of stimulus energy at F1. These findings add to the existing literature exploring the viability of the FFR as an objective technique to evaluate hearing aid fitting where stimulus bandwidth is altered by design due to frequency-specific gain applied by amplification algorithms.Note de contenu : Envelope and spectral frequency following response, Filtering, Formant frequency, Fundamental frequency, Neural phase-locking, Stimulus bandwidth DOI : 10.1097/AUD.0000000000000902|1 Disponible en ligne : Oui En ligne : https://login.ezproxy.vinci.be/login?url=http://ovidsp.ovid.com/ovidweb.cgi?T=JS [...] Permalink : https://bib.vinci.be/opac_css/index.php?lvl=notice_display&id=263878

Bruit traumatisant ; Vetéran de guerreRésumé : Objectives: Veterans who have been exposed to high-intensity blast waves frequently report persistent auditory difficulties such as problems with speech-in-noise (SIN) understanding, even when hearing sensitivity remains normal. However, these subjective reports have proven challenging to corroborate objectively. Here, we sought to determine whether use of complex stimuli and challenging signal contrasts in auditory evoked potential (AEP) paradigms rather than traditional use of simple stimuli and easy signal contrasts improved the ability of these measures to (1) distinguish between blast-exposed Veterans with auditory complaints and neurologically normal control participants, and (2) predict behavioral measures of SIN perception.
Design: A total of 33 adults (aged 19-56 years) took part in this study, including 17 Veterans exposed to high-intensity blast waves within the past 10 years and 16 neurologically normal control participants matched for age and hearing status with the Veteran participants. All participants completed the following test measures: (1) a questionnaire probing perceived hearing abilities; (2) behavioral measures of SIN understanding including the BKB-SIN, the AzBio presented in 0 and +5 dB signal to noise ratios (SNRs), and a word-level consonant-vowel-consonant test presented at +5 dB SNR; and (3) electrophysiological tasks involving oddball paradigms in response to simple tones (500 Hz standard, 1000 Hz deviant) and complex speech syllables (/ba/ standard, /da/ deviant) presented in quiet and in four-talker speech babble at a SNR of +5 dB.
Results: Blast-exposed Veterans reported significantly greater auditory difficulties compared to control participants. Behavioral performance on tests of SIN perception was generally, but not significantly, poorer among the groups. Latencies of P3 responses to tone signals were significantly longer among blast-exposed participants compared to control participants regardless of background condition, though responses to speech signals were similar across groups. For cortical AEPs, no significant interactions were found between group membership and either stimulus type or background. P3 amplitudes measured in response to signals in background babble accounted for 30.9% of the variance in subjective auditory reports. Behavioral SIN performance was best predicted by a combination of N1 and P2 responses to signals in quiet which accounted for 69.6% and 57.4% of the variance on the AzBio at 0 dB SNR and the BKB-SIN, respectively.
Conclusions: Although blast-exposed participants reported far more auditory difficulties compared to controls, use of complex stimuli and challenging signal contrasts in cortical and cognitive AEP measures failed to reveal larger group differences than responses to simple stimuli and easy signal contrasts. Despite this, only P3 responses to signals presented in background babble were predictive of subjective auditory complaints. In contrast, cortical N1 and P2 responses were predictive of behavioral SIN performance but not subjective auditory complaints, and use of challenging background babble generally did not improve performance predictions. These results suggest that challenging stimulus protocols are more likely to tap into perceived auditory deficits, but may not be beneficial for predicting performance on clinical measures of SIN understanding. Finally, these results should be interpreted with caution since blast-exposed participants did not perform significantly poorer on tests of SIN perception.DOI : 10.1097/AUD.0000000000000906|1 Disponible en ligne : Oui En ligne : https://login.ezproxy.vinci.be/login?url=http://ovidsp.ovid.com/ovidweb.cgi?T=JS [...] Permalink : https://bib.vinci.be/opac_css/index.php?lvl=notice_display&id=263920

Enfant implanté ; Implants cochléaires ; Influence socialeRésumé : Objectives: To understand the varying levels of daily cochlear implant (CI) use in children, previous studies have investigated factors that may be of influence. The objective of this study was to investigate the degree with which new child-related and environment-related characteristics were associated with consistent CI use.
Design: The design of this study was retrospective. Data were reviewed of 81 children (51% females, mean age 6.4 years with a range of 1.3 to 17.7 years) who received a CI between 2012 and 2019. Developmental status, quantified burden of comorbidity, hearing experience, and hearing environment were investigated for correlation with consistency in daily CI use. The CIs datalog was used to objectively record the wearing times. Associations were examined using univariate correlation analyses and a linear regression analysis.
Results: On average, the CI was worn 8.6 hr per day and 59% of the children wore it more than 8 hr daily. The latter children's hearing performance was significantly higher than that of the others. Consistency in CI use correlated significantly with the child-related characteristics chronological age, nonverbal intelligence quotient (IQ), American Society of Anesthesiologists physical status class, pre CI acoustic experience, CI experience, and one of the environment related characteristics "parental communication mode." In a multivariate linear regression model, consistency in CI use was significantly dependent on nonverbal IQ and parental communication mode. These together accounted for 47% of the variation in daily CI use.
Conclusions: The findings indicate that children with lower nonverbal IQ scores and low exposure to oral communication by their parents are at risk of inconsistent CI use.DOI : 10.1097/AUD.0000000000000911|1 Disponible en ligne : Oui En ligne : https://login.ezproxy.vinci.be/login?url=http://ovidsp.ovid.com/ovidweb.cgi?T=JS [...] Permalink : https://bib.vinci.be/opac_css/index.php?lvl=notice_display&id=263924

Acouphène ; Electroencéphalographie (EEG) ; Inhibition acoustique résiduelle (ARI)Résumé : Objectives: Tinnitus is the perception of sound in the absence of an external physical sound source, for some people it can severely reduce the quality of life. Acoustic residual inhibition (ARI) is a suppression of tinnitus following the cessation of a sound. The present study investigated the effect of ARI on brain activity measured using EEG.
Design: Thirty adult participants (mean age of 58 years) experiencing chronic tinnitus (minimum 2 years) participated. Participants were presented broad band noise at 10 dB above minimum masking level (1 min followed by 4 min of silence, 4 times) counterbalanced with a control treatment of broad band noise at threshold (1 min followed by 4 min of silence, 4 times) while 64-channel EEG was simultaneously recorded. Tinnitus loudness was measured using a 9-point tinnitus loudness rating scale.
Results: The ARI stimulation resulted in a self-reported reduction in tinnitus loudness in 17 of the 30 participants. Tinnitus rating reduced following stimulation but gradually returned to near baseline during 4 min of silence post sound exposure; successive sound exposures resulted in lower loudness ratings. No significant reductions in loudness rating were found with the control stimulation. The EEG showed increases in power spectral density, particularly in the alpha and gamma bands, during ARI compared to the control periods.
Conclusions: These results contribute to the understanding of ARI and tinnitus. We recommend that there be a closer examination of the relationship between onset and offset of sound in both tinnitus and nontinnitus control participants to ascertain if EEG changes seen with ARI relate to tinnitus suppression or general postsound activity.DOI : 10.1097/AUD.0000000000000907|1 Disponible en ligne : Oui En ligne : https://login.ezproxy.vinci.be/login?url=http://ovidsp.ovid.com/ovidweb.cgi?T=JS [...] Permalink : https://bib.vinci.be/opac_css/index.php?lvl=notice_display&id=263935

Titre : Band-Limited Chirp-Evoked Compound Action Potential in Guinea Pig: Comprehensive Neural Measure for Cochlear Implantation Monitoring Type de document : Article Auteurs : Youssef Adel ; Jochen Tillein ; Hannah Petzold ; Tobias Weissgerber ; Uwe Baumann Année de publication : 2021 Article en page(s) : p. 142-162 Langues : Anglais (eng) Descripteurs : HE Vinci
Electrocochléographie ; Implants cochléaires ; Pépiement (Chirp) ; Stimulation électriqueRésumé : Objectives: Patients with severely impaired high-frequency hearing and sufficient residual low-frequency hearing can be provided with a cochlear implant (CI), thereby facilitating ipsilateral electric and acoustic stimulation with established advantages over electric stimulation alone. However, partial or complete hearing loss often occurred after implantation due to, inter alia, acute mechanical trauma to cochlear structures during electrode insertion. Possibilities of intraoperative monitoring using electrocochleography (ECochG) have recently been studied in CI patients, primarily using the ongoing response to low-frequency tone bursts consisting of the cochlear microphonic (CM) and the auditory nerve neurophonic. By contrast, the transient neural response to tone bursts, that is, compound action potential (CAP), was generally less detectable or less sensitive as a monitoring measure, thus falling short of providing useful contribution to electrocochleography analysis. In this study, we investigate using chirps to evoke more robust CAP responses in a limited frequency band by synchronizing neural firing, and thereby improving CAP sensitivity to mechanical trauma in a guinea pig model of cochlear implantation.
Design: Stimuli were band-limited between 100 Hz and 10 kHz to investigate their frequency range selectivity as a preliminary model for low-frequency hearing. They were constructed by adding a harmonic series either with zero phase delay (click) or by adjusting the phase delay at a rate that is inversely related to a traveling wave delay model (chirp), with three different parameters to examine level-dependent delay compression. The amplitude spectrum was thus identical between stimuli with differences only in phase. In Experiment 1, we compared input-output functions recorded at the round window in normal-hearing guinea pigs and implemented a high-pass noise masking paradigm to infer neural contribution to the CAP. In Experiment 2, guinea pigs were implanted with a custom-built CI electrode using a motorized micromanipulator. Acute mechanical trauma was simulated during the electrode insertion. At each insertion step, CAP and CM responses were measured at the round window for the following stimuli: broad-band click, band-limited click, and band-limited chirps (3 parameters), and tone bursts at frequencies 1, 2, 4, and 8 kHz.
Results: Chirps compared with the equal-band click showed significantly lower thresholds and steeper slopes of sigmoid-fitted input-output functions. The shorter chirp evoked significantly larger amplitudes than click when compared at equal sensation level. However, the click evoked larger amplitudes than chirps at higher levels and correspondingly achieved larger saturation amplitudes. The results of the high-pass noise masking paradigm suggest that chirps could efficiently synchronize neural firing in their targeted frequency band, while the click recruited more basal fibers outside its limited band. Finally, monitoring sensitivity during electrode insertion, defined as relative amplitude change per unit distance, was higher for chirp-evoked CAP and tone burst-evoked CM, but smaller for CAP responses evoked by clicks or tone bursts.
Conclusion: The chirp was shown to be an efficient stimulus in synchronizing neural firing for a limited frequency band in the guinea pig model. This study provides a proof of principle for using chirp-evoked CAP as a comprehensive neural measure in CI patients with residual hearing.DOI : 10.1097/AUD.0000000000000910|1 Disponible en ligne : Oui En ligne : https://login.ezproxy.vinci.be/login?url=http://ovidsp.ovid.com/ovidweb.cgi?T=JS [...] Permalink : https://bib.vinci.be/opac_css/index.php?lvl=notice_display&id=263942

Titre : Do Impedance Changes Correlate With a Delayed Hearing Loss After Hybrid L24 Implantation? Type de document : Article Auteurs : Simon Konrad ; Theodor Framke ; Eugen Kludt ; Andreas Buchner ; Thomas Lenarz ; Gerrit Paasche Année de publication : 2021 Article en page(s) : p. 163-172 Langues : Anglais (eng) Descripteurs : HE Vinci
Impédancemétrie ; Implants cochléaires ; Inhibition acoustique résiduelle (ARI) ; Seuil auditifRésumé : Objectives: Preservation of residual hearing is one of the main goals in present cochlear implantation surgery. Especially for this purpose, smaller and softer electrode carriers were developed that are to be inserted through the round window membrane to minimize trauma. By using these electrodes and insertion technique, residual hearing can be preserved in a large number of patients. Unfortunately, some of these patients with initially preserved residual hearing after cochlear implantation lose it later on. The reason for this is unknown but it is speculated about a correlation with an increase in impedance, since increased impedance values are linked to intracochlear inflammation and tissue reaction. Our hypothesis for this study design was that an increase in impedance predicts changes in residual hearing under clinical conditions.
Design: Data of all adult patients (N = 122) receiving a Hybrid-L24 cochlear implant at our center between 2005 and early 2015 were retrospectively evaluated. Impedance values in Common Ground mode as measured during clinical routine and referring audiological test data (audiometric thresholds under headphones) were collected. Changes between consecutive measurements were calculated for impedance values and hearing thresholds for each patient. Correlations between changes in impedances and acoustic hearing thresholds were calculated. Average values were compared as well as patients with largest impedance changes within the observation period were evaluated separately.
Results: Group mean values of impedances were between 5 and 7 k[OMEGA] and stable over time with higher values on basal electrode contacts compared with apical contacts. Average hearing thresholds at the time of initial fitting were between 40 to 50 dB (250 Hz) and 90 dB (1 kHz) with a loss of about 10 dB compared with preoperative values. Correlation between impedance changes and threshold changes was found, but too inconsistently to imply a true relationship. When evaluating the 20 patients with the largest impedance changes during the observation period (all >1 k[OMEGA] from one appointment to the next one), some patients were found where hearing loss is timely connected and highly correlated with an unusual impedance change. But large impedance changes were also observed without affecting hearing thresholds and hearing loss was found without impedance change.
Conclusions: Changes in impedance as measured during clinical routine cannot be taken as an indicator for a late acoustic hearing loss.DOI : 10.1097/AUD.0000000000000914|1 Disponible en ligne : Oui En ligne : https://login.ezproxy.vinci.be/login?url=http://ovidsp.ovid.com/ovidweb.cgi?T=JS [...] Permalink : https://bib.vinci.be/opac_css/index.php?lvl=notice_display&id=264023

Dépistage auditif du nouveau-né ; Facteurs de risque ; Suivi médicalRésumé : Objectives: This study examines the unique factors that influence loss to follow-up after newborn hearing screening for patients at a Massachusetts urban safety-net hospital. We seek to characterize our patient population, investigate correlations between patient factors and rates of follow-up, and understand gaps in care.
Design: A retrospective chart review was conducted of patients born at an urban safety-net hospital from January 2015 through May 2018 who did not pass the newborn hearing screening in one or both ears. A total of 197 infants were included in our study. Outcomes of interest included rates and latency of follow-up appointments, infant demographics (sex, race, birth weight, risk factors for hearing loss), and maternal factors (age, marital status, smoking status, number of children).
Results: From January 2015 through May 2018, 17% (n = 34) of infants were lost to follow-up. Of those who attended an initial audiology evaluation, the median time between screening and appointment was 29 days. Newborns were 3.5 times at risk of being lost to follow-up if their mothers smoked during pregnancy compared to those whose mothers did not smoke. Further, newborns with multiple siblings in the home were less likely to utilize any audiological services. High-risk infants, such as those with an extended stay in the neonatal intensive care unit, were found to have higher rates of loss to follow-up.
Conclusions: Our results indicate that patients at urban safety-net hospitals require increased support to decrease rates of loss to follow-up. In particular, strategies to aid mothers who smoke, have multiple children, or have high-risk infants can address gaps in care for newborns after hearing screening.DOI : 00003446-202101000-00015|1 Disponible en ligne : Oui En ligne : https://login.ezproxy.vinci.be/login?url=http://ovidsp.ovid.com/ovidweb.cgi?T=JS [...] Permalink : https://bib.vinci.be/opac_css/index.php?lvl=notice_display&id=264024

Electrophysiologie auditive ; Implants cochléaires ; Nerf vestibulocochléaireRésumé : Objectives: This study aimed to create an objective predictive model for assessing the functional status of the cochlear nerve (CN) in individual cochlear implant (CI) users.
Design: Study participants included 23 children with cochlear nerve deficiency (CND), 29 children with normal-sized CNs (NSCNs), and 20 adults with various etiologies of hearing loss. Eight participants were bilateral CI users and were tested in both ears. As a result, a total of 80 ears were tested in this study. All participants used Cochlear Nucleus CIs in their test ears. For each participant, the CN refractory recovery function and input/output (I/O) function were measured using electrophysiological measures of the electrically evoked compound action potential (eCAP) at three electrode sites across the electrode array. Refractory recovery time constants were estimated using statistical modeling with an exponential decay function. Slopes of I/O functions were estimated using linear regression. The eCAP parameters used as input variables in the predictive model were absolute refractory recovery time estimated based on the refractory recovery function, eCAP threshold, slope of the eCAP I/O function, and negative-peak (i.e., N1) latency. The output variable of the predictive model was CN index, an indicator for the functional status of the CN. Predictive models were created by performing linear regression, support vector machine regression, and logistic regression with eCAP parameters from children with CND and the children with NSCNs. One-way analysis of variance with post hoc analysis with Tukey's honest significant difference criterion was used to compare study variables among study groups.
Results: All three machine learning algorithms created two distinct distributions of CN indices for children with CND and children with NSCNs. Variations in CN index when calculated using different machine learning techniques were observed for adult CI users. Regardless of these variations, CN indices calculated using all three techniques in adult CI users were significantly correlated with Consonant-Nucleus-Consonant word and AzBio sentence scores measured in quiet. The five oldest CI users had smaller CN indices than the five youngest CI users in this study.
Conclusions: The functional status of the CN for individual CI users was estimated by our newly developed analytical models. Model predictions of CN function for individual adult CI users were positively and significantly correlated with speech perception performance. The models presented in this study may be useful for understanding and/or predicting CI outcomes for individual patients.DOI : 10.1097/AUD.0000000000000916|1 Disponible en ligne : Oui En ligne : https://login.ezproxy.vinci.be/login?url=http://ovidsp.ovid.com/ovidweb.cgi?T=JS [...] Permalink : https://bib.vinci.be/opac_css/index.php?lvl=notice_display&id=264025

Titre : Acclimatization to Hearing Aids by Older Adults Type de document : Article Auteurs : Dominique Wright ; Jean-Pierre Gagné Année de publication : 2021 Article en page(s) : p. 193-205 Langues : Anglais (eng) Descripteurs : HE Vinci
Acclimatation ; Adaptation à l'aide auditive ; Aides auditives ; Reconnaissance auditive ; Sujet âgéRésumé : Objectives: Audiologists and hearing aid users (HAUs) generally agree that an adaptation period is needed following the first hearing aid (HA) experience. The main purpose of this study is to investigate the acclimatization of older adult listeners with hearing loss to HAs using listening effort and behavioral measures.
Design: Participants (N=47) were older adults with mild to moderately severe sensorineural hearing loss. Thirty-two participants were new HAUs and 15 participants were experienced HAUs. New HAUs were randomly assigned to one of two groups: noise reduction algorithms and directional microphones activated or noise reduction algorithms and directional microphones deactivated. Speech recognition in noise and listening effort were assessed on 8 different occasions during a 10-month period. A dual-task paradigm was used to measure the listening effort deployed to recognize speech in noise. The primary task consisted of the Hearing in Noise Test which also served as the behavioral speech in noise measure. The secondary task was a tactile pattern-recognition task in which participants had to identify a sequence of three tactile stimuli that varied in duration. The two listening effort outcomes were the proportional dual-task cost and the response time on the secondary task. Cognitive abilities, including working memory and speed of processing, were evaluated using the Reading Span Test and the Digit Symbol Substitution Test, respectively.
Results: Results show a significant time*group interaction. Both groups of new HAUs showed improvement over time in speech in noise performances (change of ~2 dB signal to noise ratio) and the experienced HAUs did not improve over time. The acclimatization effect was observed over a period of 4 weeks. There was no significant change over time on both measures of listening effort. There was no association between amplitude of acclimatization and the cognitive abilities measured.
Conclusion: An acclimatization effect following HA experience was observed. Specifically, the new HAUs displayed a clinically significant change of 2 dB in signal to noise ratio on the Hearing in Noise Test 4 weeks following their initial fitting. The acclimatization effect is not correlated to cognitive abilities.DOI : 10.1097/AUD.0000000000000913|1 Disponible en ligne : Oui En ligne : https://login.ezproxy.vinci.be/login?url=http://ovidsp.ovid.com/ovidweb.cgi?T=JS [...] Permalink : https://bib.vinci.be/opac_css/index.php?lvl=notice_display&id=264027

Instabilite motrice ; Test retestRésumé : Objectives: This investigation was conducted to measure the test-retest reliability of the Dizziness Symptom Profile (DSP). The DSP was developed to assist primary care providers, general otolaryngologists, and other health care providers in the development of a differential diagnosis for patients who present with dizziness, vertigo, or unsteadiness. The DSP yields a score ranging from 0 to 100% for each of 7 subscales. Each subscale represents a different diagnosis including benign paroxysmal positional vertigo, Meniere's disease, persistent postural-perceptual dizziness (PPPD), superior semi-circular canal dehiscence, vestibular migraine, vestibular neuritis, and general unsteadiness.
Design: Subjects were 150 adult patients (mean age 56.79 years, SD 15.69 years) referred to the Balance Disorders Clinic at Vanderbilt University Medical Center. Subjects completed two administrations of the DSP. The mean interval between test administrations was 1.58 days (SD 1.78 days). The response modes for the DSP were both a 0 to 100 mm visual analog scale (scored 0 mm = "strongly disagree" to 100 mm = "strongly agree") and, by extrapolation, the original 5-point Likert scale where the anchors were "strongly disagree" (scored 0 points) and "strongly agree" (scored 4 points).
Results: Pearson correlation coefficients were calculated to assess test-retest reliability for individual DSP items, and ranged from r = 0.67 to 0.91 (mean 0.80; p 0.7) with the exception of PPPD which approached 0.7. Intraclass correlation coefficient estimates and their 95% confidence intervals were also calculated to assess the relative reliability of the subscales. All 7 subscales showed moderate to strong test-retest reliability, with intraclass correlation coefficients ranging from 0.85 to 0.94. Minimal detectable change (MDC) scores were calculated to assess absolute variability/measurement error for the seven subscale scores (which range from 0 to 100%). MDC values ranged from 16% (PPPD) to 25% (unsteadiness).
Conclusions: (1) The test-retest reliability of the DSP is moderate to strong. (2) MDC values for each subscale were determined. (3) The DSP coupled with the Dizziness Handicap Inventory enables the clinician to evaluate the constructs of dizziness impairment, and disability/handicap. (4) The DSP may help provide a window to the natural history of dizziness disease(s). (5) The DSP provides a less biased assessment of the symptoms reported by the patient.DOI : 10.1097/AUD.0000000000000918|1 Disponible en ligne : Oui En ligne : https://login.ezproxy.vinci.be/login?url=http://ovidsp.ovid.com/ovidweb.cgi?T=JS [...] Permalink : https://bib.vinci.be/opac_css/index.php?lvl=notice_display&id=264029

myélineRésumé : Objectives: Individuals with early- and late-onset deafness showed different functional and morphological brain changes, but white matter alterations in both deaf groups still need to be elucidated. This study aimed to investigate changes in white matter integrity and white matter anatomical connectivity in both early- and late-onset deaf groups compared with hearing group.
Design: Diffusion tensor imaging data from 7 early-onset deaf (50.7 +/- 6.5 years), 11 late-onset deaf (50.9 +/- 12.3 years), and 9 hearing adults (48.9 +/- 9.5 years) were preprocessed using FSL software. To find changes in white matter integrity, tract-based spatial statistics was used, which implemented on FSL software. Fractional anisotropy (FA), axial diffusivity (AD) and radial diffusivity (RD) were calculated and compared among the groups with age as a nuisance variable. To find out the effect of onset age or duration of deafness to the white matter integrity, onset-age or duration of deafness was treated as a variable of interest in the general linear model implemented on tract-based spatial statistics. White matter connectivity was constructed by a deterministic tractography and compared among the groups.
Results: In comparison to the hearing group, the early-onset deaf group did not show any significant changes but the late-onset deaf group showed decreased FA and increased RD in the several white matter areas. AD in the late-onset deaf group was not significantly different compared with the hearing group. The regions included the corpus callosum, posterior and superior corona radiata, internal capsule, posterior thalamic radiation, superior longitudinal fasciculus, and tapetum of the right hemisphere. Increased RD was also additionally observed in the right external capsule, fornix, and cerebral peduncle. The onset age or duration of deafness was not significantly correlated with the white matter integrity in the early-onset deaf group. In contrast, the onset age showed a significantly positive correlation with the RD, and a negative correlation with the FA, in the late-onset deaf group. The correlated white matter areas were also similar to the findings of comparison with the hearing group. In comparison to the hearing group, the early-onset deaf group did not show altered white matter connectivity, while the late-onset deaf group showed decreased white matter connectivity in between the right lingual and hippocampal areas.
Conclusions: The present results suggest that late-onset deaf adults showed decreased FA and increased RD, and early-onset deaf adults showed no difference compared with the hearing group. In the late-onset deaf adults, onset-age showed a significantly positive correlation with RD and negative correlation with FA. Duration of deafness was not significantly correlated with the changes. Increased RD indicating demyelination occurred in the brain, and the changes were not limited to the auditory cortex but expanded to almost whole brain areas, suggesting significant effect of auditory deprivation on the brain later in life. The altered white matter connectivity in between the right limbic-occipital areas observed in the late-onset deaf group might be caused by altered language functions after auditory deprivation. Future studies are necessary incorporating functional and anatomical aspects of the brain changes in deaf group.DOI : 10.1097/AUD.0000000000000917|1 Disponible en ligne : Oui En ligne : https://login.ezproxy.vinci.be/login?url=http://ovidsp.ovid.com/ovidweb.cgi?T=JS [...] Permalink : https://bib.vinci.be/opac_css/index.php?lvl=notice_display&id=264045

Titre : Insomnia, Anxiety and Depression in Adult Cochlear Implant Users With Tinnitus Type de document : Article Auteurs : Robert H. Pierzycki ; Pádraig Thomas Kitterick Année de publication : 2021 Article en page(s) : p. 235-243 Langues : Anglais (eng) Descripteurs : HE Vinci
Acouphène ; Anxiété ; Dépression ; Implants cochléaires ; Troubles de l'endormissement et du maintien du sommeilRésumé : Objective: Determine the prevalence of clinical insomnia and its associations with anxiety, depression, and tinnitus in adult cochlear implant (CI) users.
Design: Self-reported information on tinnitus, sleep, and demographic variables was collected from adult CI users (n = 127). Tinnitus presence, its persistence, related emotional distress, and difficulties with sleep were assessed using questions from the UK Biobank study (
www.ukbiobank.ac.uk
). Tinnitus-related handicap was assessed using the Tinnitus Handicap Inventory. Clinical insomnia symptoms were characterized using the Insomnia Severity Index (ISI), and clinical anxiety and depression symptoms using the Hospital Anxiety and Depression Scale (HADS). Regression models were used to compare the data from CI users with and without tinnitus, and to test the associations between clinical insomnia, anxiety, depression and tinnitus handicap.
Results: About a half (53%) of CI users reported tinnitus, of whom 54% described it as persistent, 41% as emotionally distressing and 73% reported having difficulties with sleep based on the UK Biobank questions. The ISI suggested that clinically abnormal insomnia symptoms were more likely to occur with tinnitus (odds ratio [OR] = 2.60, 95% confidence interval 1.04 to 6.45; p = 0.040) and were found in 41% of CI users with tinnitus. Post-hoc exploratory analyses on the ISI suggested that CI users with tinnitus experienced greater levels of difficulty falling asleep, lower satisfaction with sleep patterns, greater interference of sleep problems with daily activities, and a greater impact on their quality of life. The HADS scores suggested that those with tinnitus were also more likely to have clinically abnormal anxiety (42%; OR = 3.50, 95% confidence interval 1.49 to 8.22; p = 0.004) and depression symptoms (14%; OR = 6.18, 95% confidence interval 1.17 to 32.82; p = 0.032). The clinical insomnia observed in CI users with tinnitus was associated with tinnitus handicap (p = 0.028), and the levels of clinical anxiety (p = 0.012) and depression (p
Conclusions: Clinically abnormal insomnia symptoms are prevalent, potentially affecting over 40% of CI users with tinnitus. The associations between clinical insomnia, anxiety, and depression symptoms, and tinnitus-related handicap suggest that all of these symptoms should be considered when assessing the tinnitus-related burden and its impact on the quality of life after cochlear implantation. The present findings also have potential implications for the clinical management of CI recipients with tinnitus, in whom it may be advisable to monitor sleep problems so that they can be addressed where appropriate. Further research is needed to investigate the mechanisms and causal links behind insomnia and tinnitus-related symptoms in this population. Future studies should also investigate the feasibility and effectiveness of night time use of CIs to alleviate tinnitus-related insomnia. The potential impact of insomnia on the quality of life of CI users with tinnitus highlights the importance of including sleep measures in future evaluations of the effectiveness of cochlear implantation for the alleviation of tinnitus.DOI : 10.1097/AUD.0000000000000900|1 Disponible en ligne : Oui En ligne : https://login.ezproxy.vinci.be/login?url=http://ovidsp.ovid.com/ovidweb.cgi?T=JS [...] Permalink : https://bib.vinci.be/opac_css/index.php?lvl=notice_display&id=264046

Titre : The Effect of Increasing Interphase Gap on N1 Latency of the Electrically Evoked Compound Action Potential and the Stimulation Level Offset in Human Cochlear Implant Users Type de document : Article Auteurs : Jeffrey Skidmore ; Shuman He Année de publication : 2021 Article en page(s) : p. 244-247 Langues : Anglais (eng) Descripteurs : HE Vinci
Electrophysiologie auditive ; Implants cochléaires ; Nerf vestibulocochléaireRésumé : Objective: This study reports two potential biomarkers of the physiological status of the cochlear nerve (CN) in cochlear implant users.
Design: This project represents a complementary analysis on a subset of electrophysiological data from our recently published study. This study compared changes in N1 latency and stimulation level (i.e., N1 latency offset and stimulation level offset) with increasing interphase gap of a biphasic pulse between children with cochlear nerve deficiency and children with normal-sized CNs.
Results: Children with cochlear nerve deficiency showed smaller N1 latency offsets and larger stimulation level offsets than children with normal-sized CNs at all electrode locations tested.
Conclusions: The N1 latency and stimulation level offsets differ in two patient populations with different physiological statuses of the CN. These parameters may be useful for evaluating CN function in individual cochlear implant patients.Disponible en ligne : Non En ligne : https://login.ezproxy.vinci.be/login?url=http://ovidsp.ovid.com/ovidweb.cgi?T=JS [...] Format de la ressource électronique : http://ovidsp.ovid.com/ovidweb.cgi?T=JS&CSC=Y&NEWS=N&PAGE=fulltext&D=yrovftw&AN=00003446-202101000-00022 Permalink : https://bib.vinci.be/opac_css/index.php?lvl=notice_display&id=264048
