摘　　要：目的探讨前庭下神经炎的临床特点。方法回顾性分析我科眩晕门诊就诊的8例前庭下神经炎患者资料,综合病史、查体、听力学、影像学、冷热试验及前庭诱发的肌源性电位(vestibular evoked myogenic potential,VEMP)检查结果 ,给予明确诊断。结果 8例患者眩晕发作特点均符合前庭神经炎表现,纯音听力测试及冷热试验结果 均正常,颅脑CT或MRI检查正常,排除中枢病变。VEMP8例均异常,其中6例一侧不能引出,2例一侧振幅低下。结论前庭下神经炎属于前庭神经炎的一个亚型,临床特征为病变单纯累及前庭下神经,VEMP检查可辅助诊断。对临床怀疑前庭神经炎患者应常规行VEMP检查,以利于明确诊断及评估病变范围。OBJECTIVE To evaluate the clinical features of inferior vestibular neuritis.METHODS The clinical data of 8 patients in vertigo clinic of our hospital were retrospectively analyzed.All the patients were diagnosed as inferior vestibular neuritis based on a comprehensive analysis of medical history,inspection and auditory test,radiological test,caloric test,and vestibular evoked myogenic potential（VEMP）.RESULTS The clinical features of 8 patients with vertigo were consistent with the characteristics of vestibular neuritis.The results of pure tone audiometry and caloric test were normal,and the central lesions were excluded with craniocerebral CT or MRI.Six cases had unilateral loss of vestibular evoked myogenic potential,whereas,two cases had unilateral lower amplitude of VEMP.CONCLUSION Inferior vestibular neuritis is a subtype of vestibular neuritis,which involves the inferior vestibular nerve alone.VEMP is a useful test in diagnosis of inferior vestibular neuritis.VEMP should be routinely performed in patients with vestibular neuritis,and that can help to establish the diagnosis and evaluate the extent of the lesion.
