【摘要】：目的:观察外周性前庭损害患者眼肌前庭诱发肌源性电位(oVEMP)和颈肌前庭诱发肌源性电位(cVEMP)的引出情况并探讨其临床诊断价值。方法:选择2011-03-2012-03期间在我院临床诊断为外周前庭损害,并接受门诊和(或)住院治疗的患者13例(14耳),进行双耳气导短纯音诱发的oVEMP和cVEMP检测,观察两种电位的引出情况,分析前庭上成分(椭圆/前庭上神经传入通路)和前庭下成分(球囊/前庭下神经传入通路)机能受损的状况。结果:13例(14耳,双侧1例)外周性眩晕患者包括:耳带状疱疹3例(3耳),听神经瘤3例(4耳),Ⅶ+Ⅷ颅神经牵拉伤1例(1耳),前庭神经炎2例(2耳),梅尼埃病3例(3耳),单侧内听道发育不全1例(1耳)。总体oVEMP正常引出2耳(正常引出率为14.3%),cVEMP正常引出3耳(正常引出率21.4%)。结论:外周性眩晕患者前庭耳石器及其传导通路机能受损的情况可以通过临床oVEMP和cVEMP检测进行客观评价,其表现形式根据病变波及的范围与程度不同各异。
[Abstract]:Objective: to observe the elicitation of myogenic potential (oVEMP) of ocular vestibular evoked potential (oVEMP) and (cVEMP) of vestibular evoked myogenic potential (cVEMP) in patients with peripheral vestibular injury and to explore its clinical diagnostic value. Methods: thirteen patients (14 ears) who were diagnosed as peripheral vestibular lesion in our hospital between 2011-03-2012-03 and received outpatient and / or inpatient treatment were examined for oVEMP and cVEMP induced by bicaural air conduction and short pure tone. To observe the elicitation of the two potentials and to analyze the impairment of the function of the superior vestibular component (elliptical / superior vestibular afferent pathway) and the subvestibular component (balloon / subvestibular afferent pathway). Results: thirteen patients (14 ears, 1 bilateral) with peripheral vertigo included: herpes zoster 3 (3 ears), acoustic neuroma 3 (4 ears), 鈪，
