Fenestration of the horizontal semicircular canal enables the otologic surgeon to restore hearing in those patients with congenital conductive deafness who are not candidates for stapedectomy, ossicular reconstruction, or tympanoplasty. Since the development of stapedectomy, much of the finesse technique of fenestration surgery has been lost, and many otologic surgeons today are unfamiliar with the fenestration operation. The surgical technique for creating a permanently patent fenestra in the horizontal semicircular canal is described. The causes of failure in fenestration surgery are reviewed. Thirty-three patients who have undergone fenestration for congenital conductive deafness over a 30-year period, and 100 patients who underwent fenestration for otosclerosis in 1950, are reviewed to demonstrate patient selection and the efficacy of this operation in establishing long-term hearing improvement.
水平半规管开窗术能使耳科外科医生为那些不适合镫骨切除术、听骨链重建术或鼓室成形术的先天性传导性耳聋患者恢复听力。自镫骨切除术发展以来，开窗手术的许多精细技术已经失传，如今许多耳科外科医生并不熟悉开窗手术。本文描述了在水平半规管中创建永久性开放窗口的手术技术。回顾了开窗手术失败的原因。回顾了33例在30年期间接受先天性传导性耳聋开窗手术的患者，以及1950年接受耳硬化症开窗手术的100例患者，以展示患者选择情况以及该手术在实现长期听力改善方面的疗效。
