Abstract

Background: Adenoids are common childhood upper respiratory tract problem which frequently obstruct the nasopharyngeal opening with tubal occlusion causes reduction in middle ear pressure with conductive hearing loss. Objective: To observe middle ear pressure and level of hearing in children with enlarged adenoids. Methods: This cross sectional observational study conducted among 72 children of enlarged adenoids admitted or attended in Dhaka Medical College Hospital and Bangabandhu Sheikh Mujib Medical University Dhaka. Results: 72 children of enlarged adenoids of age ranges between 5-12 years with male female ratio was 1.25:1. Mouth breathing (65.27%), hearing impairment (59.72%), nasal obstruction (55.55%) and snoring (56.94%) were the presenting symptoms of the patients. Majority of the patients of this study came from middle class (52.77%). Most of the patients with enlarged adenoids were grossly enlarged (51.38%). 43.05% grossly enlarged adenoids had significant hearing loss . In this series 65 ears (45.13%) had type A Tympanogram. 58 ears (40.27%) has Type B Tympanogram and 21 ears (14.58%) has Type C Tympanogram. Conclusion: This study revealed significant association between enlarged adenoids and conductive hearing loss of variable degree and negative middle ear pressure.
腺样体肿大对中耳压力和听力的影响
背景:腺样体是儿童常见的上呼吸道问题,常因输卵管阻塞而阻塞鼻咽开口,导致中耳压力降低并伴有传导性听力损失。目的:观察腺样体肥大患儿的中耳压力和听力水平。方法:对达卡医学院医院和Bangabandhu Sheikh Mujib医科大学收治的72名腺样体肥大儿童进行横断面观察性研究。结果:72例5~12岁腺样体肥大患儿,男女比例为1.25:1。口腔呼吸(65.27%)、听力障碍(59.72%)、鼻塞(55.55%)和打鼾(56.94%)是患者的主要症状。本研究的大多数患者来自中产阶级(52.77%)。腺样体肥大的患者大多为重度肥大(51.38%)。43.05%的重度肥大腺样体有明显的听力损失。在该系列中,65耳(45.13%)具有A型鼓室图。B型鼓室图58耳(40.27%),C型鼓室图21耳(14.58%)。结论:本研究揭示了腺样体肥大与不同程度传导性听力损失和中耳负压之间的显著联系。
