189例前庭系统性眩晕的脑干听觉诱发电位临床分析

189 Cases Brainstem Auditory Evoked Potentials(BAEP) Analysis in Vestibular System Vertigo

目的:探讨脑干听觉诱发电位(BAEP)对鉴别前庭周围性眩晕和中枢性眩晕的诊断价值。方法:对189例前庭系统性眩晕的患者进行了脑干听觉诱发电位的检查。结果:脑干听觉诱发电位异常的有151例,异常率为79.9%。其中表现为内耳型30例,占19.9%,脑干型97例,占64.2%,混合型24例,占15.9%。结论:BAEP可作为前庭系统性眩晕患者辅助诊断的一个敏感指标,对前庭系统性眩晕的临床诊断有重要的定位价值。

Objective：To explore the differential diagnosis value of in the central vestibular vertigo and peripheral vestibular vertigo.Methods：BAEP was detected in 189 patients with vestibular system vertigo.Results：BAEP were abnormal wave forms in 151 cases of the patients,the abnormality rate was 79.9 %.Including 30（19.9%） cases of inner-ear type,97（64.2%） cases of brainstem type and 24（15.9%） cases of mixed type.Conclusion：BAEP can be used as a sensitive indicator in the diagnosis of vestibular system vertigo patients,and plays an important role for the value of localization in the diagnosis of vestibular system vertigo.
