Static acoustic impedance tympanometry was used to examine 80 subjects prior to and after exposure to decreased ambient pressure in a hypobaric chamber. The predictive value of tympanometry in detecting those individuals likely to suffer from otitic barotrauma (aerotitis media) was evaluated. The results suggest that testing prior to altitude exposure is of no value in identifying those individuals who will suffer from otitic barotrauma during flight. Tympanometry however proved a useful tool in confirming the presence of barotrauma following flight, but it was no more useful than taking a history and performing an ear examination.
采用静态声阻抗鼓室图法对80名受试者在低压舱内暴露于降低的环境压力之前和之后进行检查。评估了鼓室图法在检测可能患耳气压伤（航空性中耳炎）个体方面的预测价值。结果表明，在海拔暴露前进行测试对于识别那些在飞行期间将患耳气压伤的个体没有价值。然而，鼓室图法被证明是确认飞行后气压伤存在的有用工具，但它并不比询问病史和进行耳部检查更有用。
