摘　　要：目的探讨前庭诱发肌源性电位(VEMP)对前庭下神经炎的诊断价值。方法回顾分析我科眩晕门诊18例前庭下神经炎的临床资料,尤其是VEMP检测结果。结果 18例患者中,15例表现为旋转性眩晕,3例为平衡障碍,所有患者纯音测听、冷热试验及眼性前庭诱发肌源性电位(oVEMP)正常而颈性前庭诱发肌源性电位(cVEMP)异常。其中14例cVEMP检查不能引出,4例振幅低下。3个月后复诊10例患者症状消失,复查cVEMP 9例恢复正常,1例振幅低下;半年复诊18例患者症状全部消失,复查cVEMP只有2例振幅低下,其余均恢复正常。结论 VEMP检查对前庭下神经炎的精准诊断及判断预后有重要临床价值。OBJECTIVE To invst igat e the diagnosis role of VEMP for inferior vestibular neuritis.METHODS 18 patients with inferior vestibular neuritis were studied. Especially, the oVEMP and cVEMP were recorded in all cases. RESULTS All 18 patients with VN（vertigo symptom in 15 cases, and balance disorders in 3cases） presented normal in PTA, caloric test and Ovemp test.By contrast, the cVEMPs was abnormal in all patients with VN, including flat/no amplitude of cVEMP in 14 cases, and lower amplitude in 4 cases. After three months, 10 patients recovered, with nomal amplitude of cVEMP in 9 cases and lower amplitude in 1 case. And after half-a-year-follow-up,18 patients went back to normal, with lower amplitude in only 2 cases. CONCLUSION The VEMP examination is valuable in the diagnosis and prognosis of inferior vestibular neuritis.
