This study aims to investigate the effects of adenoid hypertrophy on negative middle ear pressure and diagnostic efficiency of tympanogram in the detection of otitis media with effusion in children without parental suspicion of hearing loss.
Fifty-six children (26 boys, 30 girls; mean age 5.9±2.2 years; range, 3 to 12 years) who underwent adenoidectomy were analyzed using otoscopy, nasal endoscopy, and tympanometry (before 1 week and 3 months after adenoidectomy).
The median negative middle ear pressure before the adenoidectomy was significantly higher from after adenoidectomy (p=0.045). Type B tympanogram were detected in 13 of the 112 ears preoperatively. About 17.9% (n=20) of the ears with otitis media with effusion were confirmed by myringotomy.
Our study findings suggest that the adenoid hyperthrophy is associated with increased negative pressure in the middle ear. We believe that it is necessary to perform the middle ear examination and tympanometry in children before adenoidectomy and in children without parental suspicion of hearing loss, even.
本研究旨在探讨腺样体肥大对中耳负压的影响以及鼓室图在未被家长怀疑有听力损失的儿童中检测分泌性中耳炎的诊断效率。
对56例行腺样体切除术的儿童（26名男孩，30名女孩；平均年龄5.9±2.2岁；范围3至12岁）在腺样体切除术前1周及术后3个月进行耳镜检查、鼻内镜检查和鼓室图检查并分析。
腺样体切除术前的中耳负压中位数显著高于术后（p = 0.045）。术前112只耳中有13只检测到B型鼓室图。通过鼓膜切开术确诊17.9%（n = 20）的分泌性中耳炎耳。
我们的研究结果表明腺样体肥大与中耳负压增加有关。我们认为即使在未被家长怀疑有听力损失的儿童中，在腺样体切除术之前也有必要对中耳进行检查和鼓室图检查。
