摘要
本文总结２８例４２耳蜗后病变的瞬态诱发性耳声发射（ＴＥＯＡＥｓ）表现，不同性质蜗后病变的ＴＥＯＡＥｓ出现率分别为：中枢性低频感音神经性聋２８／２８（１００％）；听神经瘤３／１１（２７．３％）；额骨骨折２／２；脑干肿瘤０／１。对蜗后病变的ＴＥＯＡＥｓ、听性脑干电反应（ＡＢＲ）、耳蜗电图（ＥＣｏｃｈＧ）和纯音听力之间的关系进行比较和讨论。ＴＥＯＡＥｓ结合其它听力学检查方法会有助于蜗性和蜗后病变的鉴别诊断。
Abstract Trasient evoked otoacoustic emissions(TEOAEs)were recorded in 42 ears of 28 pa-tients affected with retrocochlear diseases.The presence of TEOAEs was as follows:central low-frequency sensorineural hearing losses 28/28(100%);acoustic neuromas 3/11(27.3%);temporal bone fractures 2/2;brainstem tumor 0/1.The results of TEOAEs were compared with BAR,ECochG and pure tone audiometry;The combination of TEOAEs with audiometries is helpful to the differential diagnosis between cochlear and retrocochlear diseases.
