异常声反射和语言识别率回跌(rollover)是蜗后疾患的表现。面瘫患者声反射消失也可有语言识别率回跌。作者对可以用交叉声刺激引出患侧声反射的听神经瘤患者进行研究。这些患侧面神经未受侵犯的听神经瘤患者的同侧声刺激的结果可分为:(A)镫肌反射全部消失,(B)镫肌反射部分消失,和(C)镫肌反射全都正常。在C组患者中90％以上的语言识别率回跌超过“临界比率”。经统计学处理,C组和A组间、C组和B组间,回跃比率有显著差别,而A和B组间无显著差别。声反射状态和第八神经疾患的语言识别率回
Abnormal acoustic reflexes and speech recognition rollover are manifestations of post-cochlear disorders. Acoustic reflex in patients with facial paralysis may also have language recognition rate fell back. The authors studied patients with acoustic neuromas that could elicit ipsilateral acoustic reflexes with cross-over stimulation. The results of ipsilateral sonic stimulation of these patients with acoustic neuromas who did not infiltrate the lateral nerves were categorized as: (A) all the reflexes of the goitem, (B) the disappearance of the goblet reflex, and (C) the reflexes of the goblet. More than 90% of speech recognition rates in Group C patients fell back above the “critical ratio.” Statistically, there was significant difference between the C group and A group, C group and B group, but there was no significant difference between A group and B group. Acoustic reflex status and speech recognition rate of the eighth neuropathy back
