镫骨手术能明显改善听阈,特别是在0.25～8KHz 频率范围。但手术前后,8～20KHz 频率的感觉神经性的功能,了解尚少。作者对1985～1988年所施行手术的53例耳硬化症病人(女36例,男17例,右耳26例,左耳27例)的资料进行统计分析。镫骨切开术40例,部分镫骨切除术13例。手术时根据足板窗的大小,使用不同的赝复物。38例放置 Causse 氏特氟隆袢,8例放置普通特氟隆袢,7例放置 Shea 氏特氟隆杯状活塞。在手术时根据镫骨固定状况,并将其分为四级:Ⅰ级:镫骨固定,足板无耳硬化的改变;Ⅱ级:镫骨固定,足板只有一个耳硬化病灶;Ⅲ级:镫骨固定,足板有二个以上的耳硬化病灶;Ⅳ级:前庭窗龛全部由
Tarsus surgery can significantly improve the hearing threshold, especially in the 0.25 ~ 8KHz frequency range. However, before and after surgery, 8 ~ 20KHz frequency of sensory neurological function, little is known. The authors conducted a statistical analysis of 53 patients with otosclerosis (36 males, 17 males, 26 right and 27 left ears) undergoing surgery between 1985 and 1988. Tarsus suturing in 40 cases, partial tarsal resection in 13 cases. Surgery based on the size of the foot plate window, the use of different prostheses. 38 cases placed Causse’s Teflon 袢, 8 cases placed ordinary Teflon 袢, 7 cases placed Shea Teflon cup piston. In operation under the stapes fixation, and will be divided into four levels: Ⅰ level: stapes fixation, foot-free changes in otosclerosis; Ⅱ level: stapes fixation, foot plate only one ear sclerosis; Ⅲ grade: Stapes fixation, foot plate has more than two ear sclerosis lesions; Ⅳ grade: vestibular alcove all by
