%X 目的&#65306;对比4~16岁大前庭导水管综合征(Large Vestibular Aqueduct Syndrome, LVAS)患耳与听力正常耳的宽频声能吸收率(Wideband Absorbance, WBA)谱&#65292;探讨宽频声导抗测试在大前庭导水管综合征辅助诊断中的应用价值&#65292;为未成年LVAS的诊断和预测提供参考。方法&#65306;本研究收集11例(22耳)大前庭导水管综合征患者的患耳作为实验组&#65292;并选取18例(36耳)正常未成年人作为对照组。实验组和对照组均进行宽频声导抗测试&#65292;进而对两组的共振频率和声能吸收率进行分析和对比。结果&#65306;LVAS组在1600 Hz~2900 Hz范围内平均声能吸吸收率显著低于正常组的声能吸收率&#65292;说明此范围内声能透过率较低&#65292;在5656 Hz~6535 Hz范围内LVAS组的平均声能吸收率显著大于正常组的平均声能吸收率。结论&#65306;大前庭导水管综合症患者在中频和高频段具有显著差异&#65292;共振频率低于正常人&#65292;可作为辅助大前庭导水管综合症的早期听力学检查。<br>Objective: To compare the wideband absorbance (WBA) spectra of large vestibular aqueduct syndrome (LVAS) and normal-hearing ears from 4 to 16 years old, and to explore the application value of the WBA test in the auxiliary diagnosis of LVAS, and to provide a reference for the diagnosis and prediction of LVAS in minors. LVAS diagnosis and prediction. Methods: 22 ears of large vestibular aqueduct syndrome group and 36 ears of normal group were collected. All subjects were tested by wideband acoustic immittance test, and the sound energy absorption rates of each group under peak pressure were analyzed and compared. Results: The average absorption rate of LVAS group was significantly lower than that of normal group around 1600 Hz~2900 Hz, indicating that the sound energy transmission rate was lower in this range. The average sound energy absorption rate of LVAS group was significantly higher than that of normal group in the range of 5656 Hz~6535 Hz. Conclusion: There is a significant difference between middle frequency and high frequency in patients with large vestibular aqueduct syndrome, and the resonant frequency is lower than that in normal subjects, which can be used as an assistant for early audiological examination of large vestibular aqueduct syndrome.
