Objective:To analyze the site of vestibular nerve damaged in patients with acute vestibular neuritis. Methods:Fifty-seven patients with acute vestibular neuritis were recruited, and each patient underwent caloric irrigation test, video head impulse test（vHIT） and vestibular evoked myogenic potentials（VEMPs）. The results were further analyzed. Results:Analysis of abnormal rates of different vestibular function tests: the abnormal rate of caloric irrigation test, horizontal semicircular canal vHIT, anterior semicircular canal vHIT, and posterior semicircular canal vHIT were 92.98%, 92.98%, 92.98%, and 52.63%, respectively. The abnormal rate of cervical vestibular evoked myogenic potentials（cVEMP） and ocular vestibular evoked myogenic potentials（oVEMP） were 52.63% and 89.47%. The abnormal rate of caloric irrigation test, horizontal semicircular canal vHIT, anterior semicircular canal vHIT, and oVEMP were significantly higher than posterior semicircular canal vHIT and cVEMP（P<0.01）. Combination analysis of different vestibular function tests: there are twenty-six patients（45.61%, superior and inferior vestibular nerve） with abnormal caloric irrigation test, video head impulse test, and VEMPs. There are twenty-five patients（43.86%, superior vestibular nerve） with abnormal caloric irrigation test, horizontal semicircular canal vHIT, anterior semicircular canal vHIT, and oVEMP. There are 4 patients（7.02%, inferior vestibular nerve） with abnormal posterior semicircular canal vHIT and cVEMP. There are two patients（3.51%, ampullary vestibular nerve） with abnormal caloric irrigation test, horizontal semicircular canal vHIT, and anterior semicircular canal vHIT. The rate of superior and inferior vestibular neuritis and superior vestibular neuritis were significantly higher than inferior vestibular neuritis and ampullary vestibular neuritis（P<0.01）. Conclusion:Acute vestibular neuritis subtypes can be divided into four categories: superior and inferior vestibular neuritis, superior vestibular neuritis, inferior vestibular neuritis, and ampullary vestibular neuritis. Video head impulse test can accurately assess the site of vestibular nerve damage in patients with acute vestibular neuritis. In addition, vHIT combined with VEMPs can provide objective evidence for the diagnosis of ampullary vestibular neuritis.

前庭功能检查在急性前庭神经炎患者损伤部位分析中的应用

目的：分析急性前庭神经炎患者前庭神经损伤部位。方法：纳入57例急性前庭神经炎患者，对每例患者进行热量冲洗试验、视频头脉冲试验（vHIT）和前庭诱发肌源性电位（VEMPs）。对结果进行了进一步分析。结果:不同前庭功能测试异常率分析:热量冲洗测试、水平半规管vHIT、前半规管vHIT、后半规管vHIT的异常率分别为92.98%、92.98%、92.98%、52.63% 。颈部前庭诱发肌源性电位（cVEMP）和眼部前庭诱发肌源性电位（oVEMP）异常率分别为52.63%和89.47%。热量冲洗试验、水平半规管vHIT、前半规管vHIT、oVEMP异常率显着高于后半规管vHIT、cVEMP（P<0.01）。不同前庭功能测试的组合分析：26例患者（45.61%，前庭上、下神经）热灌试验、视频头脉冲试验、VEMPs异常。25例患者（43.86%，前庭上神经）热量冲洗试验、水平半规管vHIT、前半规管vHIT、oVEMP异常。4例（7.02%，前庭下神经）后半规管vHIT和cVEMP异常。有2例患者（3.51%，壶腹前庭神经）热量冲洗试验、水平半规管vHIT、前半规管vHIT异常。上下前庭神经炎和上前庭神经炎的发生率显着高于下前庭神经炎和壶腹前庭神经炎（P<0.01）。结论：急性前庭神经炎亚型可分为四类：上、下前庭神经炎、上前庭神经炎、下前庭神经炎、壶腹前庭神经炎。视频头脉冲试验可以准确评估急性前庭神经炎患者前庭神经损伤部位。此外，vHIT联合VEMPs可为壶腹前庭神经炎的诊断提供客观证据。
