摘　　要：目的：探讨不同年龄组正常人群颈肌前庭诱发肌源性电位（cVEMP）及眼肌前庭诱发肌源性电位（oVEMP）的差异及临床意义。方法：纳入60例健康人,其中20-40岁20例,41-60岁20例,60岁以上20例。采用短纯音刺激方式,对研究对象进行前庭诱发肌源性电位检查。采用SPSS 16.0软件进行统计分析。结果：随着年龄增加,cVEMP中P1波潜伏期延长,P1-N1振幅下降,振幅不对称比增加;oVEMP中N1波潜伏期延长,N1-P1振幅下降,振幅不对称比增加。结论：随着年龄老化,耳石器反射通路时间延长、耳石器功能呈下降趋势且两侧下降程度不一致。Objective：The purpose of this study is to assess the effects of aging on air-conducted sound elicited cervical vestibular evoked myogenic potential（cVEMP）and ocular vestibular evoked myogenic potential（oVEMP）in normal people.Method：Sixty normal subjects were recruited for the vestibular evoked myogenic potential exam ination.Among them,20-40year-old group was setted as the first group,41-60year-old group was setted as the second group,〉60-year-old group was setted as the third group.Each group included 20 normal subjects.SPSS 16.0software was used to analyze the data.Result：As the age growing,P1 latency prolonged,N1-P1 amplitude decreased,and amplitude asymmetric ratio increased in cVEMP;N1latency prolonged,P1-N1 amplitude decreased,and amplitude asymmetric ratio increased in oVEMP.Conclusion：With the age growing,the time of otolithic organ input pathways prolonged,the function of otolithic organ decreased and the decrease level may be asymeetrical on both sides.
