用耳导纳计和听力计检查用同种鼓膜移植和用颞筋膜作的Ⅰ型鼓室成形术各10例。患者均无中耳病变,检查时间在术后1～6年。颞筋膜组的静态声顺值,在G220,G660,及B660都与正常值不同,B220的值在正常范围内(这相当于220 Hz的阻抗的静态声顺测定)。同种鼓膜组则只有G660与正常值不同。听力计检查结果两组无统计学意义上的差别,但临床看来用同种鼓膜的气-骨导间距缩小的 With ear admittance meter and audiometer examination using the same type of tympanic membrane transplantation and the temporal fascia for type tympanoplasty in 10 cases. Patients without middle ear lesions, check the time after 1 to 6 years. The temporal compliance of the temporal fascia group was different from normal at G220, G660, and B660, with B220 values ​​within the normal range (this corresponds to a static acoustic compliance of 220 Hz impedance). The same tympanic membrane group only G660 and normal different. There was no significant difference between the two groups in the audiometer examination, but it seems clinically that the gas-bone conduction distance of the same tympanic membrane is reduced
