摘　　要：目的 探讨交感神经皮肤反应（SSR）对不同病因所致前庭系统性眩晕的临床评定价值.方法 将120例急性前庭系统性眩晕患者分为中枢性眩晕组70例和周围性眩晕组50例,分别行SSR检测评定,并与60名健康人（正常对照组）作对照.结果 中枢性眩晕组在急性发作期SSR潜伏期延长、波幅降低,SSR总异常率为87.1%（61/70）,与周围性眩晕组及正常对照组比较,差异有统计学意义（P＜0.05）;周围性眩晕组SSR总异常率为18.0%（9/50）,潜伏期和波幅改变与正常对照组比较,差异无统计学意义（P＞0.05）.结论 前庭中枢性眩晕患者在急性发作期可出现交感神经系统功能损害,SSR检测评定可作为临床鉴别前庭中枢性眩晕和周围性眩晕的重要参考指标之一.Objective To evaluate the diagnostic value of sympathetic skin response（SSR）in patients with vestibular vertigo.Methods SSR tests were performed on 1 20 patients with acute vestibular system vertigo,including 70 cases of central vertigo and 50 eases of peripherM vertigo.60 healthy subjects were also examined to serve as controls.Results In those with central vertigo,the abnormality rate in the SSR results was 87.1%（61/70）.SSR latency was longer and its amplitude wag lower than in those with peripheral vertigo and in the heMthy controls.In those with peripheral vertigo the abnormality rate was 18.0%（9/50）,but the average latency and amplitude were not significantly different from those of the healthy controls.Conclusion Persons with acute central vestibular vertigo may have sympathetic nerve dysfunction.SSR test results can be used as an electrophysiological index to distinguish central from peripheral vestibular vertigo.
