| Résumé : | To ascertain if wideband acoustic immitance (WAI) measurements are useful in assessing crimping status following stapedotomy. Design: WAI measurements were obtained using the Mimosa Acoustics HearID system. Wideband chirp sound stimuli and a set of tone stimuli for nine frequencies between 0.2 and 6?kHz were used at 60?dB SPL. Five sets of measurements were performed on each temporal bone: mobile stapes, stapes fixation and stapedotomy followed by insertion of a tightly crimped, a loosely crimped and an uncrimped prosthesis. Study sample: Eight fresh-frozen temporal bones were harvested from human cadaveric donors. Results: At lower frequencies, up to 1?kHz, stapes fixation decreased absorbance. Compared to the baseline absorbance, absorbance with stapes fixation dropped by 6 to 17% in absolute terms from the baseline value (p?=?0.027). Absorbance was not affected in higher frequencies (p?=?0.725). Stapedotomy changed the absorbance curve significantly compared to the normal condition with an increase of absolute absorbance values by 6 to 36% around 0.25–1?kHz (p-value |
