OTITIS MEDIA EFFECT ON THE BALANCE SYSTEM

中耳炎，这是儿科最常见的疾病 临床上被认为是导致疾病恶化的原因之一 平衡。尽管中耳炎很普遍，但它对平衡的影响 功能还没有得到系统的评估。总体目标 这项建议的目的是研究前庭和平衡功能以及运动 在一个由150名2至7岁儿童组成的队列中发育，以及 确定渗出性中耳炎的近期和远期疗效 平衡和前庭系统。实验设计 包括年度前庭和平衡评估和评估 中耳状态正常时儿童的运动发育。 此外，每当中耳炎发作时，都会进行测试 鼓室切开前后渗出性中耳炎的发展 管插入。中耳状况将通过气动进行评估 耳镜、鼓室导纳和测听。前庭测试将 包括眼球运动筛查，卡路里测试，位置测试， 旋转测试、移动平台位姿图和光流 测试。粗大运动发育也将使用 皮博迪发育运动量表。这项研究将前瞻性地 建立：1)标准的适合年龄的前庭和平衡数据以及 在队列中评估前庭和平衡系统的成熟度 自出生以来有记录的中耳史的儿童；2) 渗出性中耳炎的影响，包括单侧VS的影响 双侧积液，鼓室切开置管术治疗前庭和 平衡功能和运动功能；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.
