Eustachian tube (ET) function was studied in 162 ears with otitis media with effusion (OME) and chronic otitis media (COM), using tubo-tympanoaerodynamic graphy, patency and pressure equilibration test in the inflation-deflation test. Severe impairment of active opening function was found in both OME children and adults compared with that of COM patients. This impairment in active opening was thought to result from functional obstruction of the ET in 71.8% of OME children and 51.8% of OME adults. However, 45.6% of OME adults had an organic obstruction while such was present only in 28.2% of OME children. We deduce from this study that impaired active opening function of the ET in both OME children and adults is the result of functional obstruction rather than organic obstruction, but organic obstruction is considered to be related to the pathogenesis of OME in adults.
采用咽鼓管-鼓室气动力学造影、通畅性及充气-放气试验中的压力平衡测试，对162例分泌性中耳炎（OME）和慢性中耳炎（COM）患者的咽鼓管（ET）功能进行了研究。与COM患者相比，OME儿童和成人的主动开放功能均严重受损。在71.8%的OME儿童和51.8%的OME成人中，这种主动开放功能的损害被认为是由ET的功能性阻塞所致。然而，45.6%的OME成人存在器质性阻塞，而只有28.2%的OME儿童存在这种情况。我们从这项研究中推断，OME儿童和成人ET的主动开放功能受损是功能性阻塞而非器质性阻塞的结果，但器质性阻塞被认为与成人OME的发病机制有关。
