作者们认为,目前鼓室压测定在临床上的广泛使用已由于超过此项阻抗器械能力的测量资料的解释而变得复杂。本文的研究是为了估价达一方法在耳科临床上的诊断价值,并对其对中耳疾病的筛选价值作出结论。作者们研究了成年男性的204耳。均做测听和显微耳镜检查,并尽可能拍照记录耳镜所见。显微鼓气耳镜因难以精确调节压力故未全部都做这种检查。鼓室压测定是用Grayson-Stadler1720B型器械于220赫和660赫作声纳和声导曲线,在研究相关关系时用220赫声纳曲线。作者们将鼓室阻抗图分为:正常压力:+50
The authors argue that the wide clinical use of tympanometry at present is complicated by the interpretation of measurement data that exceeds the impedance device’s capabilities. The purpose of this study is to evaluate the diagnostic value of one method in the clinical study of otology, and to conclude its value in the screening of middle ear diseases. The authors studied 204 ears of adult men. Audiometry and microscopic otoscopy were done, and try to take pictures recorded otoscopy see. Microscopic drum otoscope because it is difficult to accurately regulate the pressure so not all do this check. Tympanometry was performed using a Grayson-Stadler Model 1720B instrument at 220 Hz and 660 Hz as a sonar and acoustic guide curve, using a 220 Hz sonar curve when studying the correlation. The authors divided the tympanogram into: Normal Pressure: +50
