This study aims to compare the characteristics of Wideband Acoustic Immittance (WAI) in Chinese infants under three months of age, with either normal or abnormal middle ear function.
We recruited 98 infants with either normal or abnormal middle ear function, and subsequently divided them into four groups based on their middle ear function and chronological age. The absorbances at tympanometric peak pressure (TPP) were collected across 1/3rd octave frequencies ranging from 226 to 8000 Hz.
Among infants with normal middle ear function, no significant differences were observed concerning ear laterality. However, significant differences were noted at 3364 Hz and 4000 Hz with respect to age. For infants with either normal or abnormal middle ear function, we found significant differences at the majority of frequencies. Additionally, the receiver operating characteristic (ROC) curves and maxima Youden index indicated that absorbances at 1682 Hz and 1297 Hz could be employed to evaluate the middle ear function of infants at 1 and 2 months of age.
This study demonstrates that WAI holds promise as a valuable tool for assessing the middle ear condition of infants at 1 and 2 months of age. Infants aged 1 and 2 years, having absorbance values equal to or greater than 0.7470 at 1682 Hz and 0.6775 at 1297 Hz respectively, may indicate normal middle ear function. Furthermore, it underscores the necessity of establishing ethnicity- and age-specific norms for WAI in infants under 3 months of age.
本研究旨在比较三个月以下中耳功能正常和异常的中国婴儿的宽频声导抗（WAI）特征。
我们招募了 98 名中耳功能正常和异常的婴儿，随后根据中耳功能和年龄将他们分为四组。在 226 至 8000 Hz 的 1/3 倍频程频率范围内收集声导抗测试峰压（TPP）的吸光度。
在中耳功能正常的婴儿中，耳侧别无显著差异。然而，在 3364 Hz 和 4000 Hz 频率上，年龄有显著差异。对于中耳功能正常和异常的婴儿，我们在大多数频率上都发现了显著差异。此外，受试者工作特征（ROC）曲线和最大 Youden 指数表明，1682 Hz 和 1297 Hz 的吸光度可用于评估 1 至 2 个月龄婴儿的中耳功能。
本研究表明，WAI 有望成为评估 1 至 2 个月龄婴儿中耳状况的有用工具。1 至 2 岁的婴儿，如果在 1682 Hz 处的吸光度值等于或大于 0.7470，在 1297 Hz 处的吸光度值等于或大于 0.6775，则可能表明中耳功能正常。此外，它强调了在 3 个月以下婴儿中建立 WAI 的种族和年龄特异性正常值的必要性。
