眩晕在儿童不常见,但近年有所增多。有提出咽鼓管功能障碍、有或无中耳渗液,是儿童前庭机能障碍或眩晕的常见原因。本文研究中耳渗液对前庭的影响。一组患中耳渗液一年以上、无中耳感染的儿童100例,年龄4～7岁,平均6.3岁。由父母填表提供患儿平衡失调症状,均作神经学检查及鼓膜、纯音测听、鼓室图、眼震电图(ENG)等检查,与50名正常儿童及25名鼓膜切开放管后干耳的儿童相比较。结果:3例因中耳急性感染除外,余97例纯音测听语言听阈为20～45dB,平均28.9dB;鼓室图均为B型或C型;均为双侧性,仅2例双耳轻重不等;ENG显示35例(36%)有自发性水平性眼震,22例(22.7%)有位置性眼震,12例(12.4%)以上两眼震均有,ENG总异常率为69例(71%)。自发性眼震均单向
Vertigo is uncommon in children but has increased in recent years. Eustachian tube dysfunction is proposed, with or without middle ear effusion, is a common cause of children with vestibular dysfunction or dizziness. This article studies the effect of middle ear effusion on the vestibule. A group of middle ear exudate more than one year, 100 children without middle ear infection, aged 4 to 7 years, mean 6.3 years. All the patients were asked to fill in the questionnaire to provide the children with balance disorders. All the patients were examined with neurological examination, tympanic membrane, pure tone audiometry, tympanogram and ENG, and 50 normal children and 25 tympanic membranes Ear children compared. Results: Except acute infection of the middle ear in 3 cases, the hearing threshold of 97 pure tone audiophiles was 20 ~ 45 dB with an average of 28.9 dB; tympanogram was B or C type; ENG showed 35 cases (36%) had spontaneous horizontal nystagmus, 22 cases (22.7%) had positional nystagmus, 12 cases (12.4%) had nystagmus and ENG, and the total abnormal rate of ENG was 69 Example (71%). Spontaneous nystagmus are unidirectional
