为揭示前庭功能正常者的紧张性前庭反应是否不对称,作者观察了100例无前庭损害临床表现者的前庭动眼反应和前庭脊髓反应。受检者均无心血管、神经和前庭系统疾病,视力正常,无药物和酒精中毒史,无其他有害因素影响。受检者分二组:一组50例,年龄19～27,男22女28,无耳病,鼓膜正常;二组50例,为排除迷路外因素影响而设,又分三个亚组。2_a组21人,年龄16～28,男10女11,一耳在2.5～11年前曾行根治手术,术腔干愈,另耳正常;2_b组18人,年龄17～21男12女6,一耳鼓膜干性穿孔;2_c组11人,年龄22～38,男6女5,双耳在3.5～14年中行过根治手术,术腔干愈。观察各种前庭动眼和前庭脊髓反应,用ENG记录眼震,肉眼观测前庭脊髓反应,但用肌力计测试前臂肌张力。用相对不对称系数表示反应的不对称性(按Jongkees公式计算:
To reveal whether the tonic vestibular response in patients with normal vestibular function is asymmetric, the authors observed 100 patients with clinical manifestations of vestibular anastomosis and vestibular spasm reaction. Subjects had no cardiovascular, neurological and vestibular system diseases, normal vision, no drug and alcoholism history, no other harmful factors. Subjects were divided into two groups: a group of 50 cases, aged 19 to 27, 22 men and 28 women, no ears, normal tympanic membrane; two groups of 50 cases, to eliminate the impact of labyrinthine factors, is divided into three subgroups. 2_a group of 21 people, aged 16 to 28, 10 men and 11 women, one ear had radical surgery 2.5 to 11 years ago, the curettage more, the other ear normal; 2_b group 18, aged 17-21 male 12 female 6 , A dry eardrum perforation; 2c group of 11 people, aged 22 to 38, 6 men and 5 women, both ears in 3.5 to 14 years underwent radical surgery, dry the cavity. Various types of vestibular and vestibular spinal responses were observed, nystagmles were recorded with ENG, vestibular spinal responses were visualized with the naked eye, but the brachial muscle tension was measured using a strength meter. The relative asymmetry coefficient is used to indicate the asymmetry of the reaction (calculated according to the Jongkees formula:
