Twenty-three patients suffering from secretory otitis media were examined. The mean age of the group was 6 years. Adenoidectomy and insertion of polyethylene tympanostomy tubes was made. The tubal function was studied by measuring the middle ear pressure on the morning after operation and once a month during the following five months by using the air pressure equilibration technique. In 23 ears (79%) the pressure was considered to be normal and in 10 ears (30%) abnormal at the first measurement. After 5 months the corresponding groups were 26 (79%) and 7 (21%).
对23例分泌性中耳炎患者进行了检查。该组患者的平均年龄为6岁。实施了腺样体切除术并插入了聚乙烯鼓膜造孔管。通过在术后次日早晨以及随后五个月每月一次使用气压平衡技术测量中耳压力来研究咽鼓管功能。首次测量时，23只耳朵（79%）的压力被认为正常，10只耳朵（30%）异常。5个月后，相应的组别分别为26只耳朵（79%）和7只耳朵（21%）。
