139 patients, 80 boys and 59 girls aged 1 1/4--13 1/2 years suffering from serous otitis media based on otoscopy and tympanometry had adenoidectomy performed and no other surgical measures taken. The efficiency of the treatment was assessed 2--4 months later. Intially flat tympanometry curves were found in 155 ears, negative middle ear pressure in 70 ears and low curves in 20 ears. 78% of all ears and 73% of the ears with flat curves were seen to normalize during the observation periods.
139例年龄在1又1/4至13又1/2岁的患儿（80名男孩和59名女孩），经耳镜检查和鼓室声导抗测试确诊为浆液性中耳炎，接受了腺样体切除术，未采取其他手术措施。在2至4个月后评估治疗效果。最初，155只耳朵的鼓室声导抗曲线呈平坦型，70只耳朵中耳压力为阴性，20只耳朵为低曲线。在观察期内，所有耳朵中有78%以及曲线平坦的耳朵中有73%恢复正常。
