脑干听觉诱发电位在前庭中枢性眩晕临床分类诊断中的作用

摘要

目的 探讨脑干听觉诱发电位在前庭中枢性眩晕临床分类诊断中的作用.方法 从本院2014年9月至2016年9月收治的前庭系统性眩晕患者中随机选择90例进行研究,设为观察组,并选择90例健康者设为对照组.对两组研究对象进行脑干听觉诱发电位检测,观察两组各波的分化情况,并进行比较.结果 对照组波形均分化良好,观察组中有67例(74％)脑干听觉诱发电位异常,其中中枢性眩晕39例(58％)、周围性眩晕28例(42％).两组的脑干听觉诱发电位结果进行比较,可得其Ⅰ-Ⅲ、Ⅲ-Ⅴ、Ⅰ-Ⅴ波PL和Ⅰ～Ⅲ、Ⅲ-Ⅴ、Ⅰ-Ⅴ波IPL差异均有统计学意义(均P＜0.05).结论 利用脑干听觉诱发电位可以对前庭中枢性眩晕进行良好的临床分类诊断.%Objective To explore the clinical value of brainstem auditory evoked potentials in the clinical classification diagnosis of central vestibular system vertigo.Methods 90 patients with vestibular system vertigo in our hospital from September 2014 to September 2016 were selected as the observation group,and 90 healthy people were selected as the control group.The subjects of two groups were detected by brainstem auditory evoked potentials,and observed the differentiation of the two groups.Results The waveform of the control group was well differentiated;there were 67 cases (74％) of abnormal brainstem auditory evoked potentials in the observation group,including 39 cases (58％) of central vertigo and 28 cases (42％) of peripheral vertigo.There were statistically significant differences in the results of brainstem auditory evoked potentials (PL and IPL of Ⅰ-Ⅲ,Ⅲ-Ⅴ,Ⅰ-Ⅴ waveform) between the two groups (P＜0.05).Conclusion Brainstem auditory evoked potentials has good clinical value in the clinical classification diagnosis of central vestibular system vertigo.
