【摘要】：目的:觀察外周性前庭損害患者眼肌前庭誘發(fā)肌源性電位(oVEMP)和頸肌前庭誘發(fā)肌源性電位(cVEMP)的引出情況并探討其臨床診斷價值。方法:選擇2011-03-2012-03期間在我院臨床診斷為外周前庭損害,并接受門診和(或)住院治療的患者13例(14耳),進行雙耳氣導短純音誘發(fā)的oVEMP和cVEMP檢測,觀察兩種電位的引出情況,分析前庭上成分(橢圓/前庭上神經(jīng)傳入通路)和前庭下成分(球囊/前庭下神經(jīng)傳入通路)機能受損的狀況。結(jié)果:13例(14耳,雙側(cè)1例)外周性眩暈患者包括:耳帶狀皰疹3例(3耳),聽神經(jīng)瘤3例(4耳),Ⅶ+Ⅷ顱神經(jīng)牽拉傷1例(1耳),前庭神經(jīng)炎2例(2耳),梅尼埃病3例(3耳),單側(cè)內(nèi)聽道發(fā)育不全1例(1耳)�？傮woVEMP正常引出2耳(正常引出率為14.3%),cVEMP正常引出3耳(正常引出率21.4%)。結(jié)論:外周性眩暈患者前庭耳石器及其傳導通路機能受損的情況可以通過臨床oVEMP和cVEMP檢測進行客觀評價,其表現(xiàn)形式根據(jù)病變波及的范圍與程度不同各異。
[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，
