咽鼓管功能状况与中耳疾患的诊疗和鼓室成形术的疗效有密切关系,是航空专业人员体检的重要项目。其测试方法亦在不断发展中。利用声阻抗计测试咽鼓管功能,不仅在鼓膜完整情况下可以测试;鼓膜穿孔时亦同样可以进行。近年来有关这方面的报道日渐增多,现择要介绍于下。一、鼓膜完整时测试方法从鼓室功能曲线(typanogram或鼓室压曲线)可以初步判断咽鼓管功能。一般说来,咽鼓管功能正常者大多为正常A型曲线,峰压点在士25mm H_2O范围内,咽鼓管功能不良者多为负压型(C型)或平坦型(B型)曲线;咽鼓管异常 Eustachian tube function and middle ear disease diagnosis and treatment and tympanoplasty are closely related to the effectiveness of aviation professionals is an important item of physical examination. Its testing methods are also evolving. The use of acoustic impedance meter test Eustachian tube function, not only in the tympanic membrane integrity can be tested; tympanic membrane perforation can also be carried out. In recent years, there has been a growing number of reports in this area, and we now want to introduce them below. First, the tympanic membrane integrity test method from the tympanic function curve (typanogram or tympanic pressure curve) can initially determine the eustachian tube function. In general, most patients with normal eustachian tube function is normal type A curve, peak pressure point in the 25mmH_2O range, dysfunctional uterine Eustachian tube mostly negative pressure (C type) or flat type (B type) curve Eustachian tube abnormalities
