Abstract: OBJECTIVE To invstigate 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 3 cases) 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.
