In order to determine the prevalence of hearing impairment and otitis media in rural primary school children, a pilot study of 284 children aged 6-10 years was performed. These children were screened by otoscopy, pure tone audiometry and tympanometry. The overall prevalence of otological abnormalities (excluding wax) was 21.5%. Hearing impairment was detected in 34 children (11.9%). Conductive hearing impairment was predominant (10.9%). Otitis media was diagnosed in 17.6% of children. While 91.2% of children with hearing impairment had associated middle ear disease, only 53.4% of those with middle ear disease were detected as have hearing impairment. The importance of including tympanometry as part of the screening protocol is highlighted.
为了确定农村小学生听力障碍和中耳炎的患病率，对284名6至10岁的儿童进行了一项试点研究。这些儿童通过耳镜检查、纯音听力测定和鼓室图检查进行筛查。耳部异常（不包括耵聍）的总体患病率为21.5%。在34名儿童（11.9%）中检测到听力障碍。传导性听力障碍占主导（10.9%）。17.6%的儿童被诊断为中耳炎。虽然91.2%的听力障碍儿童伴有中耳疾病，但中耳疾病儿童中只有53.4%被检测出有听力障碍。强调了将鼓室图检查纳入筛查方案的重要性。
