Abstract：
BACKGROUND: When adenoids enlarge and elicit symptoms it is referred to as symptomatic adenoids, which is a preventable cause of hearing loss and nasal obstruction in the pediatric age group. This study was done to correlate conductive hearing loss with the size of adenoids and to emphasize the importance of screening in the pediatric age group.
METHODS: An observational case-control study was conducted to analyze the degree of hearing impairment in children with adenoid hypertrophy. In total, 98 patients with at least one symptom of adenoid hypertrophy aged between 5 and <15 years were recruited. Those with conductive hearing loss were in the case group and those with normal hearing were in the control group. Audiometry, tympanogram, X-ray, and fibreoptic nasal endoscopy were conducted and compared.
RESULTS: The mean age of presentation of conductive hearing loss with adenoids was 7.67 years. The mean conductive hearing loss on audiometry was 31.69 dB. Tympanogram showed a type B curve in 40.81% of ears and type C in 26.53%. On X-ray nasopharynx, the majority of cases had grade III hypertrophy followed by grade II and grade IV. In nasal endoscopy, most cases had second-degree adenoid hypertrophy followed by third degree, first degree, and then fourth degree. The highest degree of hearing loss of 32-48 dB was present with fourth-degree adenoids. Conductive hearing loss was five times more in patients with third- and fourth-degree adenoids.
CONCLUSIONS: In our study, adenoid hypertrophy has a positive correlation with conductive hearing loss in pediatric patients. So proper screening and early management should be done to prevent hearing loss in children.

摘要：
背景：当腺样体增大并引起症状时，它被称为有症状的腺样体，这是儿童年龄组听力损失和鼻塞的可预防原因。这项研究旨在将传导性听力损失与腺样体的大小相关联，并强调在儿科年龄组进行筛查的重要性。
方法：进行观察性病例对照研究，分析腺样体肥大患儿的听力损害程度。总的来说,招募了98名年龄在5至<15岁之间的至少一种腺样体肥大症状的患者。传导性听力损失者为病例组，听力正常者为对照组。测听法,鼓室图,X光片,并进行纤维鼻内镜检查。
结果：伴有腺样体的传导性听力损失的平均年龄为7.67岁。测听法的平均传导性听力损失为31.69dB。鼓室图显示40.81%的耳朵为B型曲线，26.53%为C型曲线。在X射线鼻咽上，大多数病例有III级肥大,其次是II级和IV级.在鼻内窥镜检查中，大多数病例有二度腺样体肥大，其次是三度，一级,然后是第四学位。四度腺样体的听力损失程度最高，为32-48dB。患有三度和四度腺样体的患者的传导性听力损失是后者的五倍。
结论：在我们的研究中，腺样体肥大与儿童传导性听力损失呈正相关。因此，应进行适当的筛查和早期管理，以防止儿童听力损失。
