retrocochlear

基本解釋

Since 53% of retrocochlear disorders also had an abnormal ECochG, diagnosis of cochlear disorders must depend on normal BSR and abnormal ECochG.
ECochG異常而BSR正常才能診斷為蝸內(nèi)病變; 蝸后病變的診斷主要根據(jù)BSR,但也有賴于EcochG。
Conclusions:It was comfirmed that the inner ear antigens come from different part of auditory system,which could cause cochlear or retrocochlear autoimmune disease.
結(jié)論：組織抗原性質(zhì)差異，可造成自身免疫性內(nèi)耳病理損傷部位和聽損類型各不相同，即可表現(xiàn)為耳蝸性聾或蝸后性聾。
Conclusion Auditory screening by OAE had high sensitivity, but also there were a few false negative cases in practices.Some cases with hearing loss due to retrocochlear disease would be missed.
結(jié)論耳聲發(fā)射是靈敏度較高的新生兒聽力篩查方法，但是有一定的假陰性率，對于各種原因造成的蝸后聽覺通路病變所致的耳聾可能會漏診。
Method:Seventeen subjects (34 ears) with normal hearing,13 ears with cochlear hearing loss and 9 ears with retrocochlear hearing loss were studied on their DPOAE and contralateral suppression.
方法：研究以白噪聲為對側(cè)聲刺激，對17例正常人(34耳)，13例蝸性聾(13耳)，9例蝸后聾(9耳)進(jìn)行了DPOAE及其對側(cè)抑制效應(yīng)測試。
