To study the method on comprehensive evaluation of the middle ear function in children with secretory otitis media (SOM) after tympanotomy tube insertion.
Ear canal volume (ECV), pure tone audiometry and distortion product otoacoustic emission(DPOAE) were carried out in 31 children(43 ears) with SOM before and 1 month after tube insertion,in the meantime Eustachian tube function was recorded. The tympanotomy tube was observed under microscope.
After one month of tube insertion, the hearing level was improved in 39 ears with an ECV > 2.0 ml. In addition,the detection rate and amplitude of DPOAE were significantly increased in these 39 ears. No case of the function of Eustachian tube was complete recovered.
ECV, pure tone audiometry, DPOAE and inflation-deflation test are significantly clinical worth for comprehensive evaluation of the middle ear function in children with SOM after tympanotomy tube insertion.
探讨鼓膜置管术后分泌性中耳炎（SOM）患儿中耳功能综合评估方法。
对31例（43耳）SOM患儿在鼓膜置管术前及置管后1个月进行耳道容积（ECV）、纯音听力测试及畸变产物耳声发射（DPOAE）检测，同时记录咽鼓管功能。在显微镜下观察鼓膜置管情况。
置管1个月后，39耳ECV＞2.0 ml者听力水平提高，且这39耳DPOAE检出率及幅值明显增加。咽鼓管功能无1例完全恢复。
ECV、纯音听力测试、DPOAE及鼓室压力变化试验对鼓膜置管术后SOM患儿中耳功能综合评估具有重要临床价值。
