本文报告了1975～1979年内有外伤或用力病史而突发感觉神经性聋8例,均经鼓室探查证实为圆窗破裂,其中3例卵圆窗及圆窗均有破裂。窗破裂处分别用耳垂脂肪、筋膜、静脉瓣,有的加用明胶海绵修补。作者们提出对怀疑有圆窗膜破裂的病例可绝对卧床并用镇静剂三、四天,每日测听,当测听结果无改进时则是手术探查之指征。手术探查所见:8例圆窗膜破裂病例中,5例显示有异常浅的,面向外的圆窗龛。1例为潜水员,潜水110英尺深上升时发病,术中见圆窗龛处空虚无膜,轻探证实为广泛开放,鼓阶几乎干涸。因此作者们告诫术中不可在圆窗龛处吸引,因可能造成中阶膜或螺旋器的损伤,可用无耳毒性的棉花小拭子或泡沫海绵轻轻吸净圆窗龛的血和外淋巴液。 In this paper, we report 8 cases of sudden sensory deafness with history of trauma or force from 1975 to 1979, all of which were ruptured by tympanometry, of which 3 cases had rupture of oval window and round window. Window rupture, respectively, with earlobe fat, fascia, venous flap, and some plus gelatin sponge repair. The authors suggest that patients with suspected rupture of round window membranes should be left lying in bed for three to four days with daily tranquillizers, and indications for surgical exploration should there be no improvement in audiometry. Surgical exploration findings: 8 cases of round window membrane rupture cases, 5 cases showed abnormal shallow, outward facing round window niche. One case was a diver who had a 110-foot-deep dive and had an onset of disease. During the operation, he saw an empty membrane at the round window niche, and the photolithography proved to be widely open and the drum stage almost dried up. Therefore, the authors warn intraoperative should not be attracted in the round window niche, as may cause the middle-stage membrane or spiral injury, available non-ototoxic cotton swabs or foam sponge gently suck the circular window niche blood and perilymph liquid.
