摘　　要：目的 探讨前庭神经炎患者颈肌性前庭诱发电位(cervical vestibular evoked myogenic potential,cVEMP)检测的临床意义。方法选取2011年4月～2012年10月武警总医院眩晕研究所病房收治的前庭神经炎患者65例,正常对照组选自武警总医院健康工作人员48例,所有研究对象均行听力学检查和前庭功能检查。前庭功能检查包括冷热试验为水平半规管功能检查,主要反映前庭上神经功能;cVEMP为球囊功能检查,主要反映前庭下神经功能。结果65例前庭神经炎患者冷热试验结果均异常,其中45例cVEMP检测结果异常,异常率为69.2%。48例正常对照者中冷热试验结果均正常,其中2例cVEMP检测结果异常,异常率为4.2%。两组cVEMP检测比较差异具有显著性(χ2=18.3712,P=0.005)。结论cVEMP可以反映前庭神经炎患者前庭下神经分支的受累情况,对进一步认识和诊断前庭神经炎临床类型有一定价值。Objective To evaluate the clinical significance of cervical vestibular evoked myogenic potential（cVEMP） in vestibular neuritis. Methods Sixty five patients with diagnosis of vestibular neuritis at Department of Otorhinolaryngology, General Hospital of Chinese People＇s Armed Police Forces from April 2011 to October 2012 and 48 normal persons as control group were included in our study. Auditory and vestibular function test were carried out in all the patients and normal persons. Caloric test was used to measure horizontal semicircular canal and superior vestibular nerve function, while cVEMP was used to evaluate the function of saccule and inferior vestibular nerve. Results Forty five cases of all the 65 patients（69.2%） with vestibular neuritis had an abnormal cVEMP result. In the control group, only 2 out of 45（4.2%） had an abnormal eVEMP result. There was significant difference between both groups（x^2= 18.3712, P=0.005 ）. Conclusion Vestibular neuritis mostly involves the superior portion of the vestibular nerve.
