摘　　要：目的　探讨耳鸣与椎 基底动脉缺血发作 (VBI)的关系。方法　对有耳鸣的VBI患者作脑干听觉诱发电位 (BAEP)和听力检查 ,以无耳鸣的VBI患者作为对照组。结果　耳鸣组各波的潜伏期 (PL)明显延长 ,波Ⅰ最显著 ,随着各波的出现 ,这种差异变小 ,各波峰间期 (IPL)改变不明显 ,常有程度不同的听力障碍。结论　耳鸣应是VBI的常见或早期症状 ,BAEP有助于VBI的诊断。Objective To study the relation of the tinnitus and vertebrobasilar transient ischemic attacks (VBI).Methods The determination of brainstem auditory evoked potentials (BAEP) and auditory disorders is given to the patients of VBI with tinnitus.The patients of VBI without tinnitus are as a control group.Results The peak latency (PL)of all waves is significantly leng in the group of VBI with tinnitus.Wave I is the longest in PL.With presence of the posterior waves,this difference is gradually getting small.The changes of interpeak latencies(IPL)of wave Ⅰ～Ⅲ,Ⅲ～Ⅴ and Ⅰ～Ⅴ are not significant.The patients of VBI with tinnitus often have minor auditory disorders.Conclusion The tinnitus is may be earlier symptom and often complain of VBI.BAEP is useful to the diagnosis of VBI.
