眼震视图与脑干听觉诱发电位在前庭性偏头痛临床诊断中的应用

Application of Videonystagmusgraphy and Brainstem Auditory Evoked Potentialin the Clinical Diagnosis of Vestibular Migraine

目的探讨眼震视图(VNG)和脑干听觉诱发电位(BAEP)在前庭性偏头痛(VM)临床诊断中的应用价值。方法选取2017年8月至2019年12月就诊于南京医科大学康达学院附属连云港中医院的50例VM患者作为观察组,选取同期30例健康成年人作为对照组,均接受VNG和BAEP检查。比较两组VNG和BAEP检查结果。结果VNG结果显示,观察组自发性眼震试验、扫视试验、视动试验、平稳跟踪试验和冷热试验异常率高于对照组(P<0.05),两组凝视试验异常率比较,差异无统计学意义(P>0.05)。观察组BAEP异常率高于对照组,BAEP的波峰潜伏期(PL)和峰间潜伏期(IPL)长于对照组(P<0.05)。结论部分VM患者的VNG和BAEP检查结果存在异常,VNG和BAEP同步检查有助于VM患者的临床诊断。

Objective To study the application value of videonystagmusgraphy(VNG)and brainstem auditory evoked potential(BAEP)in the clinical diagnosis of vestibular migraine(VM).Methods A total of 50 patients with VM who were treated in Lianyungang TCM Hospital Affiliated to Kangda College of Nanjing Medical University from August 2017 to December 2019 were selected as observation group,and 30 healthy adults were selected as control group during the corresponding period.All of them were given VNG and BAEP examination.The results of VNG and BAEP examination were compared between the two groups.Results VNG results showed that the abnormal rates of spontaneous nystagmus test,saccade test,optokinetic test,smooth pursuit tracking test and caloric test in observation group were higher than those in control group(P<0.05).There was no statistical difference in the abnormal rate of gaze test between the two groups(P>0.05).The abnormal rate of BAEP in observation group was higher than that in control group(P<0.05).The peak latency(PL)and interpeak latency(IPL)of BAEP in observation group were longer than those in control group(P<0.05).Conclusion VNG and BAEP examination results of some patients with VM were abnormal.Synchronous examination of VNG and BAEP is helpful to the clinical diagnosis of patients with VM.
