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.
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。
