OTITIS MEDIA EFFECT ON THE BALANCE SYSTEM

中耳炎是小儿最常见的疾病， 在临床上被认为是导致疾病恶化的原因之一。 平衡 尽管这种流行性中耳炎，其影响的平衡， 功能尚未得到系统评价。 总体目标 研究前庭和平衡功能以及运动 在150名2至7岁儿童的队列中进行的发育研究， 确定分泌性中耳炎的短期和长期影响 对平衡和前庭系统的影响 实验设计 包括每年的前庭和平衡评估， 中耳状态正常时儿童的运动发育。 此外，每当耳炎发作时， 中耳积液的发展与鼓膜切开术前后一样 插管 中耳状态将通过气动 耳镜检查、鼓室检查和听力检查。 前庭测试将 包括眼动筛查，热量测试，位置测试， 旋转测试、移动平台姿势描记术和光流 试验.大运动发育也将使用 皮博迪运动发育量表。 这项研究将前瞻性地 建立：1）标准年龄相适应前庭和平衡数据， 评估队列中前庭和平衡系统的成熟度 自出生以来有记录的中耳病史的儿童; 2） 分泌性中耳炎的疗效，包括单侧与 双侧积液，前庭和鼓室置管 平衡功能和运动功能;以及3）前庭的哪些方面 功能受到中耳炎和可能的适应机制的影响。

Otitis media, which is the most common disease in the pediatric population, is believed clinically one of to cause a deterioration of balance. Despite this prevalence of otitis media, its effect on balance function has not been systematically evaluated. The overall objectives of this proposal are to study vestibular and balance function and motor development in a cohort of 150 children ages 2 to 7 years, and determine the short- and long-term effects of otitis media with effusion on the balance and vestibular system. The experimental design includes yearly vestibular and balance evaluations and assessment of motor development of children when middle ear status is normal. Additionally, testing will be performed whenever an episode of otitis media with effusion develops as well as before and after tympanotomy tube insertion. Middle ear status will be assessed with pneumatic otoscopy, tympanometry, and audiometry. Vestibular testing will consist of ocular-motor screening, caloric testing, positional testing, rotational testing, moving platform posturography, and optic flow testing. Gross motor development also will be evaluated using the Peabody Developmental Motor Scale. This study will prospectively establish: 1) normative age-appropriate vestibulr and balance data and evaluate the maturation of the vestibular and balance system in a cohort of children with documented middle ear history since birth; 2) the effect of otitis media with effusion, including the effect of unilateral vs Bilateral effusion, and tympanotomy tube insertion on vestibular and balance function and motor function; and 3) which aspects of vestibular function are affected by otitis media and possible adaptive mechanisms.
