One hundred and ninety-four patients with a sensation of ear fullness were examined with the audiometry, tympanometry, and tubotympanoaero-dynamic graphy (TTAG) as a eustachian tube ventilatory test. In 74 cases of 194, the eustachian tube dysfunction was thought to cause an ear fullness sensation and patulous tube was found in 19 patients which is more frequent than expected. Functional unbalance of the both eustachian tubes which results from minimum ventilatory disturbance on the complaining side was also thought to be one of the causes of this symptom. The eustachian tube dysfunctions like stenotic or patulous tube could not be fully diagnosed by the audiometry and tympanometry because most patients with the eustachian tube dysfunctions showed normal middle ear pressure measured by the tympanometry. From our study, it could be concluded that eustachian ventilatory test like TTAG was very available in the patient with an ear fullness feeling which is one of the most common symptoms in the otolaryngological field.
对194例有耳闷感的患者进行了听力测定、鼓室导抗图检查以及咽鼓管鼓室气流动态图检查（TTAG）作为咽鼓管通气功能测试。在194例患者中，有74例被认为咽鼓管功能障碍导致耳闷感，其中19例发现咽鼓管异常开放，其发生率高于预期。主诉侧最小通气障碍导致的双侧咽鼓管功能失衡也被认为是该症状的原因之一。由于大多数咽鼓管功能障碍患者的鼓室导抗图显示中耳压力正常，因此听力测定和鼓室导抗图无法完全诊断咽鼓管狭窄或异常开放等功能障碍。从我们的研究可以得出结论，像TTAG这样的咽鼓管通气功能测试对于有耳闷感的患者非常有用，耳闷感是耳鼻喉科领域最常见的症状之一。
