镫骨切除术采用钢丝-特氟隆法或不锈钢活塞法,其成功率在95％以上。然而要取得听力的持久改善,应对此手术失败的原因清楚了解。作者们统计在1961—1971年间的1000余例镫骨切除术中,需行再次探查术者82例。本文则重点分析其中44例,共56次探查术,原病均为耳硬化症,随访最少一年。听力下降的类型简单分类如下:(1)持久性或复发性传导性聋;(2)在语言频率范围的明显感觉神经性聋;(3)混合性聋,语言频率骨导下降,但气-骨导差仍显著,语言识别力往往降低,或兼有眩晕症状。分述如下:
Tarsus resection using wire - Teflon or stainless steel piston method, the success rate of 95% or more. However, to achieve lasting improvement in hearing, a clear understanding of the reasons for the failure of this operation should be clear. Authors statistics in more than 1000 cases of osteotomy in 1961-1971, 82 cases need to revisit the operation. This article focuses on analysis of which 44 cases, a total of 56 exploration techniques, the original disease are otosclerosis, at least one year follow-up. The categories of hearing loss are briefly categorized as follows: (1) persistent or recurrent conductive deafness; (2) significant sensory nerve deafness in the linguistic frequency range; (3) mixed deafness with reduced language frequency bone conduction, Bone conduction is still significant, language recognition is often reduced, or both dizziness symptoms. As follows:
