【摘要】：目的 探討紅外視頻眼震圖在外周性眩暈鑒別診斷中的應用價值。 方法： 對120例外周性眩暈患者(梅尼埃病40例、良性陣發(fā)性位置性眩暈58例、前庭神經(jīng)元炎12例、突發(fā)性耳聾伴眩暈8例,遲發(fā)性膜迷路積水2例),上述疾病的診斷標準參見文獻)進行紅外視頻眼震圖(videonystagmography VNG)檢查,同時選擇30例健康人作為對照組。研究組和對照組均采用美國的Micromedical視頻眼震圖系統(tǒng)行前庭功能檢查,檢查內(nèi)容依次包括：掃視、平穩(wěn)追蹤、視動試驗、自發(fā)性眼震、搖頭試驗、位置試驗、變位試驗及前庭雙溫試驗。 結果 研究組VNG檢查記錄：掃視試驗8例異常；平穩(wěn)追蹤17例異常,視動試驗7例異常；出現(xiàn)自發(fā)性眼震14例(11.67%),出現(xiàn)位置性眼震55例(45.83%),前庭雙溫試驗異常共48例：其中梅尼埃病30例(30/40),良性陣發(fā)性位置性眩暈4例(4/58),前庭神經(jīng)元炎5例(5/12),突發(fā)性耳聾伴眩暈的7例(7/8),遲發(fā)性膜迷路積水2例。 對照組VNG檢查記錄：掃視試驗3例異常,平穩(wěn)追蹤6例異常,視動試驗2例異常,無自發(fā)性眼震,無位置性眼震,前庭雙溫試驗異常1例。 結論 1.眼動功能評價對外周性眩暈的診斷意義不大,但有助于外周性眩暈和中樞性眩暈的鑒別診斷。 2.不同的外周性眩暈,VNG有不同的特征性表現(xiàn)。VNG對外周性眩暈的鑒別診斷有重要價值。
[Abstract]:Objective to evaluate the value of infrared video nystagmus in differential diagnosis of peripheral vertigo. Methods: 120 cases of peripheral vertigo (40 cases of Meniere's disease, 58 cases of benign paroxysmal positional vertigo, 12 cases of vestibulitis, 8 cases of sudden deafness with dizziness and 2 cases of delayed membrane labyrinth hydrops) were examined by (videonystagmography VNG). 30 healthy people were selected as control group. Both the study group and the control group were examined by Micromedical video nystagmus system in the United States. The contents of the examination included scanning, steady tracking, visual movement test, spontaneous nystagmus, head shaking test, position test, displacement test and vestibule double temperature test. Results in the study group, 8 cases were abnormal in scan test, 17 cases were abnormal in stable follow-up test, 7 cases were abnormal in visual movement test, 8 cases were abnormal in scan test, 7 cases were abnormal in visual movement test. Spontaneous nystagmus occurred in 14 cases (11.67%), positional nystagmus occurred in 55 cases (45.83%). Abnormal vestibule double temperature test was found in 48 cases: Meniere's disease in 30 cases (30 鈮，
