This study aims to compare the examination results of the vestibular evoked myogenic potential（VEMP） and video head impulse testing（vHIT） in patients with vestibular neuritis（VN）, thus exploring the methods to distinguish superior and inferior vestibular nerve damages in VN patients, and their feasibility. A total of 25 patients with unilateral VN treated in the Otology Department of the First Hospital of Qinhuangdao from May 2018 to July 2021 were recruited. They were respectively tested for ocular VEMP（oVEMP）, cervical VEMP（cVEMP） and vHIT, and the examination results were analyzed. Examination results of oVEMP showed that 96%（24/25） patients had one-ear abnormalities with the amplitude decline or no waveform introduced, and 4%（1/25） patient had no waveform introduced of both ears. The overall abnormal rate examined by oVEMP was 100%（26/26）. Examination results of cVEMP showed that 36%（9/25） patients had one-ear abnormalities with the amplitude decline or no waveform introduced, and 4%（1/25） patients had no waveform introduced of both ears. The overall abnormal rate examined by cVEMP was 40%（10/25）, and 60%（15/25） patients had normal waveforms of both ears. Examination results of vHIT showed that 100%（25/25） patients had semicircular canal gain decline of one side, 92%（23/25） had anterior Semicircular canal decline of one side, and 36%（9/25） had posterior semicircular canal decline of one side. VEMP and vHIT results were compared. Examination results of VEMP showed that 60%（15/25） VN patients had superior vestibular nerve damage, and 40%（10/25） had both superior and inferior vestibular nerve damages. Examination results of vHIT showed that 64%（16/25） VN patients had superior vestibular nerve damage, and 36%（9/25） had both superior and inferior vestibular nerve damages. There was no significant difference in the ratio of VN patients with superior and inferior vestibular nerve damages examined by VEMP or vHIT（²=0.085, >0.05）. The matching ratio of VEMP and vHIT results was 80%（20/25）, and the non-matching ratio was 20%（5/25）. Consistent results obtained from both VEMP and vHIT can preliminarily identify the type of vestibular nerve damage. If their results are not consistent, it is recommended not to identify the scope of the vestibular nerve damage.
本研究旨在比较前庭神经炎（VN）患者的前庭诱发肌源性电位（VEMP）和视频头脉冲测试（vHIT）的检查结果，从而探索区分VN患者前庭上下神经损伤的方法及其可行性。招募了2018年5月至2021年7月在秦皇岛市第一医院耳鼻喉科接受治疗的25例单侧VN患者。分别对他们进行眼震VEMP（oVEMP）、颈震VEMP（cVEMP）和vHIT测试，并对检查结果进行分析。oVEMP检查结果显示，96%（24/25）的患者单耳异常，表现为波幅下降或未引出波形，4%（1/25）的患者双耳均未引出波形。oVEMP检查的总体异常率为100%（26/26）。cVEMP检查结果显示，36%（9/25）的患者单耳异常，表现为波幅下降或未引出波形，4%（1/25）的患者双耳均未引出波形。cVEMP检查的总体异常率为40%（10/25），60%（15/25）的患者双耳波形正常。vHIT检查结果显示，100%（25/25）的患者一侧半规管增益下降，92%（23/25）的患者一侧前半规管下降，36%（9/25）的患者一侧后半规管下降。比较VEMP和vHIT结果。VEMP检查结果显示，60%（15/25）的VN患者存在前庭上神经损伤，40%（10/25）的患者前庭上下神经均损伤。vHIT检查结果显示，64%（16/25）的VN患者存在前庭上神经损伤，36%（9/25）的患者前庭上下神经均损伤。VEMP或vHIT检查的VN患者前庭上下神经损伤比例无显著差异（²=0.085，>0.05）。VEMP和vHIT结果的匹配率为80%（
