摘要
借助声导抗仪进行定量的Valsalva和反Valsalva咽鼓管鼓室功能测试，得出正常人Valsalva法引起的中耳声顺变化值为0．57±0．23ml，反Valsalva法为0．26±0．12ml。不同咽鼓管功能状态者，其鼓室的压力和顺应性明显影响测值。提示本测试对咽鼓管狭窄、阻塞或开放均有诊断意义；此外，根据声导抗仪所描记的曲线也可分析咽鼓管功能障碍的类型和程度，作为临床治疗的参考指标；本方法具有简便、定量等优点。
This paper studied a simplified and quantified valsalva and reverse valsalva maneu-ver eustachian tube tympanometry with otoadmittance meter. In normal groups, the compliance changes were 0. 57±0. 23 ml with valsalva maneuver and 0. 26±0. 12 ml with reverse valsalva ma-neuver. Otherwise,the recordings were performed in various tympanic functions induced by various eustachian tube functions,and the results showed that this method was significant for the diagnosis of eustachian tube structure,obstruction or patency. The recording curves helped to determine the types and degrees of eustachian tube abnormality.
