前庭神经炎视频头脉冲测试结果的动态变化

A follow-Up Study with the Video Head Impulse Test for the patients with vestibular neuritis

目的:运用视频头脉冲试验(vHIT)了解前庭神经炎(VN)患者不同时间半规管高频区的受损程度及恢复进程。方法:收集单侧急性VN患者29例,总结并分析其一般资料及急性期、1个月、3个月vHIT结果。结果:29例VN患者急性期水平半规管、上半规管、后半规管异常率分别为89.7%、86.2%、44.8%;发病1个月时水平半规管、上半规管、后半规管恢复率分别为23.8%、75.0%、15.4%;至发病3个月水平半规管、上半规管、后半规管恢复率为47.1%、87.5%、25.0%。结论:vHIT可有效动态检测VN患者半规管高频区的受损和恢复情况;上半规管功能受损恢复最好,水平半规管次之。

Objective:To detect the impairment degree and recovery process of the semicircular canals of patients with vestibular neuritis(VN)by video head impulse test(vHIT)over different periods.Method:The clinical data of patients with VN,who were diagnosed by Vertigo clinic’physicians in the Department of ENT,Dalian Municipal Central Hospital from Sept.2018 to Sept.2019,were analyzed and followed up at 1 and 3 month.The damage degree and recovery process of each semicircular canal function were evaluated by vHIT.Result:During the onset period,89.7%horizontal semicircular canal HSC,86.2%anterior semicircular canal ASC and 44.8%posterior semicircular canal PSC were abnormal in 29 patients.23.8%HSC were back to normal,75.0%ASC were back to normal,15.4%PSC were back to normal at 1 month;47.1%HSC were back to normal,87.5%ASC were back to normal,25.0%PSC were back to normal at 3 month.Conclusion:vHIT can effectively and dynamically detect the damage and recovery of the high-frequency region of the semicircular canal in patients with VN;the damaged function of the ASC is best recovered,followed by the HSC.
