Methods The GSI-16 clinical two channel audiometer with built in sound field system was used to observe 143 cases(168 ears)with various hearing aids.

应用GSI-16纯音听力计附声场测听系统，观察168耳不同类型助听器使用者助听前的听力损失和助听后的听力补偿；测试裸耳及佩戴不同类型耳内式助听器后外耳道共振峰幅值；测试22耳耳内式助听器使用者的言语分辨率。

objective to explore the clinical characteristics and treatment of external auditory canal cholesteatoma.

目的 探讨外耳道胆脂瘤的临床特征和治疗方法。

Objective In order to explore the effect of oto-endoscope on aural media operation.

目的探讨耳内镜在门诊外耳道疾病治疗中的应用价值。

The tissues round the tragus was not enough to make the tragus in the patients who had cavity of auricular concha or external auditory canal reconstructed . So the free composite tissue of residual ear ,which will be deserted in the reconstructed auricular repair usually , could be used to make the tragus .

对于存在耳甲腔或外耳道再造后，仍无耳屏的患者，拟再造耳屏的周边组织量有限，不足以行耳屏的再造，而采用多余的残耳复合游离移植，则可以合理利用组织，组织的成活率高，再造的耳屏形状良好。

Result:The content of cholesteatoma tissues and postauricular skin specimens are a normal euploid.
