【摘要】：目的 探讨红外视频眼震图在外周性眩晕鉴别诊断中的应用价值。 方法： 对120例外周性眩晕患者(梅尼埃病40例、良性阵发性位置性眩晕58例、前庭神经元炎12例、突发性耳聋伴眩晕8例,迟发性膜迷路积水2例),上述疾病的诊断标准参见文献)进行红外视频眼震图(videonystagmography VNG)检查,同时选择30例健康人作为对照组。研究组和对照组均采用美国的Micromedical视频眼震图系统行前庭功能检查,检查内容依次包括：扫视、平稳追踪、视动试验、自发性眼震、摇头试验、位置试验、变位试验及前庭双温试验。 结果 研究组VNG检查记录：扫视试验8例异常；平稳追踪17例异常,视动试验7例异常；出现自发性眼震14例(11.67%),出现位置性眼震55例(45.83%),前庭双温试验异常共48例：其中梅尼埃病30例(30/40),良性阵发性位置性眩晕4例(4/58),前庭神经元炎5例(5/12),突发性耳聋伴眩晕的7例(7/8),迟发性膜迷路积水2例。 对照组VNG检查记录：扫视试验3例异常,平稳追踪6例异常,视动试验2例异常,无自发性眼震,无位置性眼震,前庭双温试验异常1例。 结论 1.眼动功能评价对外周性眩晕的诊断意义不大,但有助于外周性眩晕和中枢性眩晕的鉴别诊断。 2.不同的外周性眩晕,VNG有不同的特征性表现。VNG对外周性眩晕的鉴别诊断有重要价值。
[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，
