摘要
目的:探讨RamsayHunt综合征患者听性脑干诱发电位(ABR)改变。方法:对36例单侧发病,对侧耳正常的RamsayHunt综合征患者进行纯音测试及ABR检查。以健侧耳为对照,分析双耳Ⅰ、Ⅲ、Ⅴ波潜伏期及Ⅰ～Ⅲ、Ⅰ～Ⅴ、Ⅲ～Ⅴ间期的差异。结果:RamsayHunt综合征患者的患侧耳Ⅲ、Ⅴ波潜伏期及Ⅰ～Ⅲ、Ⅰ～Ⅴ间期较健侧耳延长,其差异有统计学意义(P<0.05)。结论:RamsayHunt综合征患者常存在听觉通路损害,表现为蜗性损害、蜗后损害或蜗性损害并发蜗后损害,单纯蜗性损害较少见。
Objective:To discuss the changes of the auditory brain stem response in patients with Ramsay Hunt syndrome.Method:Thirty-six patients of Ramsay Hunt syndrome,who have only unilateral involvement with contralateral good ear,were studied with pure tone test and auditory brain stem response.The latencies of peaksⅠ,Ⅲand Ⅴ and interpeak latencies ofⅠ～Ⅲ,Ⅰ～Ⅴand Ⅲ～Ⅴin bilateral ears were analyzed by SPSS 10.0 for windows.Result:Compared to the controlateral,the affected ears were significantly increased in latencies of Ⅲ,Ⅴ and interpeak latencies ofⅠ～Ⅲ,Ⅰ～Ⅴ (P<0.05).Conclusion:The audiological data suggested that cochlear or retrocochlear involvement or involvement at more than one site along the auditory pathway existed in Ramsay Hunt syndrome, but pure cochlear hearing loss is not common.
