| الوصف: | Purpose: The aims of this study were to develop normative data for wideband acoustic immittance (WAI) measures in Caucasian and Australian Aboriginal children and compare absorbance measured at 0 daPa (WBA(0) ) and tympanometric peak pressure (TPP; WBA(TPP)) between the 2 groups of children. Additional WAI measures included resonance frequency, equivalent ear canal volume, TPP, admittance magnitude (YM), and phase angle (YA).Method: A total of 171 ears from 171 Caucasian children and 87 ears from 87 Aboriginal children who passed a test battery consisting of 226-Hz tympanometry, transient evoked otoacoustic emissions, and pure tone audiometry were included in the study. WAI measures were obtained under pressurized conditions using wideband tympanometry. Data for WBA(0,) WBA(TPP), YM, and YA were averaged in one-third octave frequencies from 0.25 to 8 kHz.Results: There was no significant ear effect on all of the 7 measures for both groups of children. Similarly, there was no significant gender effect on all measures except for WBA(TPP) in Aboriginal children. Aboriginal boys had significantly higher WBA(TPP) than girls at 1.5 and 2 kHz. A significant effect of ethnicity was also noted for WBA(TPP) at 3, 4, and 8 kHz, with Caucasian children demonstrating higher WBA(TPP) than Aboriginal children. However, the effect size and observed power of the analyses were small for both effects.Conclusion: This study developed normative data for 7 WAI measures, namely, WBA(0) , WBA(TPP), TPP, Veq, RF, YM, and YA, for Caucasian and Aboriginal children. In view of the high similarity of the normative data between Caucasian and Aboriginal children, it was concluded that separate ethnic-specific norms are not required for diagnostic purposes. |
