Résumé : | To study the developmental characteristics of sweep frequency impedance (SFI) measures in healthy infants from birth to 6 months. Design: All infants were assessed using high-frequency tympanometry (HFT), distortion product otoacoustic emission (DPOAE) and SFI tests. SFI measures consisted of measurement of resonance frequency (RF) and mobility (?SPL) of the outer and middle ear. A mixed model analysis of variance was applied to the SFI data to examine the effect of age on RF and ?SPL. Study sample: Study included 117 ears from 83 infants of different age groups from birth to 6 months. Results: The mean RF of the outer ear increased from 279?Hz at birth to 545?Hz at 4 months, whereas mean ?SPL of the outer ear decreased from 7.9?dB at birth to 3.7?dB at 4 months of age. In contrast, the mean RF and ?SPL of the middle ear did not change significantly with age up to 6 months. Conclusions: Developmental characteristics should be considered when evaluating the function of the outer and middle ear of young infants (?6 months) using the SFI. The preliminary normative SFI data established in this study may be used to assist with the evaluation. |
