With the use of the tubal compliance test and the forced response test (FRT), the compliance and ventilatory functions of the eustachian tube (ET) were examined in 19 children with otitis media with effusion (OME) and cleft palate, in 31 children with OME but without cleft palate, and in 19 individuals with traumatic perforation of the eardrum without history of other otological disease (controls). The tubal compliance results in the group with both cleft palate and OME were significantly higher than the results obtained with the controls, but did not differ significantly from the results obtained with the patients with OME but without cleft palate; this indicated that the ETs of those patients with OME and cleft palate, and the ETs of those patients with OME but without cleft palate, appeared to be more collapsible than the ETs of normal subjects. It was speculated that such an aerodynamic property of the ET observed in the group with OME and cleft palate and in the group with OME but without cleft palate may be due mainly to possible inflammatory condition of the tubal mucosa rather than to abnormal anatomy or to an abnormal physical property of the framework (such as cartilage) of the ET.
通过使用咽鼓管顺应性测试和强迫反应测试（FRT），对19例患有中耳积液（OME）和腭裂的儿童、31例患有OME但无腭裂的儿童以及19例有鼓膜外伤性穿孔且无其他耳科疾病史的个体（对照组）的咽鼓管（ET）顺应性和通气功能进行了检查。腭裂合并OME组的咽鼓管顺应性结果显著高于对照组，但与单纯OME患者组的结果无显著差异；这表明，患有OME和腭裂的患者以及患有OME但无腭裂的患者的咽鼓管似乎比正常受试者的咽鼓管更易塌陷。据推测，在OME合并腭裂组和单纯OME组中观察到的咽鼓管这种空气动力学特性，可能主要是由于咽鼓管黏膜可能存在的炎症状态，而非由于解剖结构异常或咽鼓管框架（如软骨）的物理特性异常。
