retrocochlear

基本解释

Since 53% of retrocochlear disorders also had an abnormal ECochG, diagnosis of cochlear disorders must depend on normal BSR and abnormal ECochG.
ECochG异常而BSR正常才能诊断为蜗内病变; 蜗后病变的诊断主要根据BSR,但也有赖于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.
结论：组织抗原性质差异，可造成自身免疫性内耳病理损伤部位和听损类型各不相同，即可表现为耳蜗性聋或蜗后性聋。
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.
结论耳声发射是灵敏度较高的新生儿听力筛查方法，但是有一定的假阴性率，对于各种原因造成的蜗后听觉通路病变所致的耳聋可能会漏诊。
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：研究以白噪声为对侧声刺激，对17例正常人(34耳)，13例蜗性聋(13耳)，9例蜗后聋(9耳)进行了DPOAE及其对侧抑制效应测试。
retrocochlear amplitude measurement
