摘要
目的:探讨老年性耳聋患者脑干听觉诱发电位改变特征,为临床研究和早期防治提供依据。方法:对90例老年性耳聋患者采用美国产VIKINGQUEST型肌电/诱发电位仪进行检测。结果:90例脑干听觉诱发电位异常率100%,主要表现在仅V波可见39只耳,Ⅰ、Ⅲ、Ⅴ波未引出6只耳,Ⅰ波缺失2只耳,Ⅰ、Ⅲ、Ⅴ波分化差34只耳,I波峰潜伏期延长56只耳,Ⅰ~Ⅴ峰间期延长15只耳,Ⅰ~Ⅲ峰间期延长7只耳,Ⅲ~Ⅴ/Ⅰ~Ⅲ>121只耳,两耳间波峰潜伏期与峰间期之差大于0.3ms10只耳。结论:老年性耳聋患者不仅有耳蜗功能的损害,也可有蜗后的病变。
Objective: To explore the features of brainstem auditory evoked potential (BAEP) in deafness of aged people. It would provide the basis for the clinical study and treatment. Methods: BAEP were examined in 90 patients with deafness in aged people. Results: The abnormal rate was 100%. Wave Ⅰ disappeared in 2 ears; wave Ⅰ and wave Ⅲ disappeared in 39 ears; wave Ⅰ , and wave Ⅲ and wave Ⅴ disappeared in 6 ears. The undifferentiated wave were recorded in 34 ears. The latency of wave Ⅰ were delayed in 56 ears. The inter- peak latency of wave Ⅰ- Ⅴ were delayed in 15 ears, wave Ⅰ- Ⅲwere delayed in 7 ears. Ⅲ -Ⅴ/Ⅰ - Ⅲ〉 1 were 21 ears. The difference of latency and the inter - peak latency more than 0. 3ms between two ears in 10 ears. Conclusion: It suggests the patients with deafness have cochlewr functional damage and diseases after cohlea.
