镫骨手术经常遇到大片的耳硬化灶充满与闭塞前庭龛,且术后有再闭塞之倾向,这种病例常因耳蜗功能不良而不适宜施行传统的内耳开窗术,因此许多学者主张采用前庭窗径路,其成功率约83～86％。作者给1000例患者作了1157次镫骨底板切除术,其中138次术后又发生了闭塞(相当于手术次数的11.93％;患者人数的11.2％),作者连续地给109例耳硬化性闭塞病例作了前庭窗手术,方法如下:9例采用静脉移植及聚乙烯管;100 Tarsus surgery often encounter a large area of ​​otorhinolaryngitis full and occlusion of the vestibule, and postoperative occlusion tendency, this case often due to cochlear dysfunction and not suitable for the traditional inner ear fenestration, many scholars advocate the use of The vestibular window path, the success rate of about 83 ~ 86%. The authors performed 1,157 stapes resections on 1000 patients, of which 138 were occluded after surgery (equivalent to 11.93% of the number of procedures; 11.2% of patients). The authors gave 109 consecutive otosclerosis occlusions Case made of vestibular surgery, as follows: 9 cases of vein graft and polyethylene pipe; 100
