Tympanometry is a new procedure in determining the status of the middle ear and can be helpful in assessing the function of the eustachian tube. Of 274 male aviators examined, 174 were normal, 40 cases had acute aerotitis media, and 60 cases had chronic aerotitis media. Impedance audiometry and pure tone audiometry were carried out by means of an electroacoustic impedance bridge and audiometer, respectively. Altitude chamber test was also performed. This study presents the results of tympanometry and inflation-deflation test in aviators. The normal average static compliance is 0.75 cc. Most normal aviators and patients with chronic aerotitis media in remission show a type A tympanogram, whereas type B and type C tympanograms are characteristic of acute aerotitis media. It is of interest that patients with chronic aerotitis media do not response normally to the inflation-deflation tympanometric tests. Tympanometry has been proved to be a very useful adjunct in the evaluation of the aerotitis media in aviators.
鼓室导抗测量法是确定中耳状况的一种新方法，有助于评估咽鼓管的功能。在接受检查的274名男性飞行员中，174人正常，40例患有急性航空性中耳炎，60例患有慢性航空性中耳炎。分别通过电声阻抗桥和听力计进行声阻抗测听和纯音测听。还进行了高空舱测试。本研究展示了飞行员鼓室导抗测量法和鼓膜张缩试验的结果。正常平均静态声顺为0.75毫升。大多数正常飞行员和处于缓解期的慢性航空性中耳炎患者呈现A型鼓室图，而B型和C型鼓室图是急性航空性中耳炎的特征。有趣的是，慢性航空性中耳炎患者对鼓膜张缩鼓室导抗测试反应不正常。鼓室导抗测量法已被证明是评估飞行员航空性中耳炎的一种非常有用的辅助手段。
