To gain a clear idea of the function of middle ear and hearing in cleft palate with secretory otitis media after pressure equalization tube insertion.
53 cleft palate cases with secretory otitis media including 62 ears were divided into treatment and control groups. They were examined by tympanogram and hearing threshold.
Hearing threshold in treatment group after PE tube insertion respectively was 23.3 dB and 23.4 dB in the near future and at a specified future date. It was normal. But there were still 64% tympanogram B and C.
PE tube insertion could solve hearing problem, but could not improve the function of middle ear.
明确腭裂伴分泌性中耳炎患者在插入通气管后中耳功能及听力情况。
将53例腭裂伴分泌性中耳炎患者（共62耳）分为治疗组和对照组。通过鼓室图和听力阈值进行检查。
治疗组插入通气管后近期及特定远期的听力阈值分别为23.3分贝和23.4分贝，听力正常。但仍有64%的鼓室图为B型和C型。
插入通气管可解决听力问题，但不能改善中耳功能。
