In an attempt to distinguish normal from abnormal eustachian tube function, two groups of adults with nonintact tympanic membranes were tested. Six subjects had traumatic perforations of the tympanic membrane and a negative otologic histroy while five subjects had perforations as a sequela of otitis media. The subjects were tested with two methods: the middle ear inflation-deflation technique and a newly introduced forced-response technique. The comparison of the two groups revealed marked differences between normal subjects and patients with middle ear disease in active tubal dilation mechanisms and biomechanics of the eustachian tube. The forced-response test appeared to be a better method to determine the degree of actual tubal function.
为了区分咽鼓管功能正常与异常，对两组鼓膜不完整的成年人进行了测试。6名受试者鼓膜有外伤性穿孔且耳部病史阴性，而5名受试者的穿孔是中耳炎的后遗症。采用两种方法对受试者进行测试：中耳充-放气技术和新引入的强制反应技术。两组对比显示，正常受试者与中耳疾病患者在咽鼓管主动扩张机制和生物力学方面存在显著差异。强制反应测试似乎是确定咽鼓管实际功能程度的更好方法。
