摘要(Abstract)：

本文分析了同侧镫骨肌声反射反向曲线在不同程度听力损失,不同性质耳聋以及各型鼓室压图中的出现率。引起反向曲线的刺激声强度一般为100～125dB(spl)(1000Hz),以115dB 为多见;反向曲线出现率随听力损失程度的增加而增高;患有各种性质耳聋的耳反向曲线,出现率均比正常耳高;鼓膜听骨链活动度增高(AD 型)或降低(As 型)的耳,其反向曲线出现率均此正常鼓室压图(A 型)者高。本文还报道了 B 型鼓室压图者也出现了反向曲线。
The author discuss the incidence of the directional inverse curve in ipsila- teral stapedial reflex measurement among patients with different degrees of hea- ring loss,different causes of deafness and differens types of tympaogram. Generally,the sound intensities used to evoke the curve were 100-125dB SPL (1000 Hz). The incidence of this curve was increased propnrtionally with the degreo of hearing loss,and manifested mainly in ears with median or profound deafness (82.69%).It appeared more frequent in deaf ears and ears with increased(AD) or decreased(AS)tympanogram than normal ears significantly(p<0.05). The highest incidence(48.72%)was observed in ears with AS type tympanogram. The author found that this carve could also appear in ears with B type tympa- nogram.
