目的探讨脑干听觉诱发电位对鉴别前庭周围性眩晕和中枢性眩晕的诊断价值。方法对106例临床诊断为前庭系统性眩晕的患者进行了脑干听觉诱发电位的检测。结果脑干听觉诱发电位异常的有76例,异常率为71.6%。其中表现为外周性29例,中枢性47例。结论脑干听觉诱发电位对前庭系统性眩晕患者听通路受损的检出具有较高的敏感性,对于鉴别周围性眩晕和中枢性眩晕有重要的参考价值。 Objective To investigate the diagnostic value of brainstem auditory evoked potentials in the differential diagnosis of peripheral vertigo and central vertigo. Methods The brainstem auditory evoked potentials were detected in 106 patients with clinically diagnosed vestibular systemic vertigo. Results There were 76 abnormal brainstem auditory evoked potentials, the abnormal rate was 71.6%. Which showed peripheral 29 cases, central 47 cases. Conclusions Brainstem auditory evoked potentials are highly sensitive to the detection of auditory pathway impairment in patients with vestibular system vertigo. It is of great value in distinguishing peripheral vertigo from central vertigo.
