For more than 15 years, rupture of the round window membrane has been discussed as a possible cause of sudden sensineural hearing loss. With regard to the pathophysiological basis for such a rupture, an abnormality in the width of the aquaeductus cochlearis as well as anatomical variations of the round window membrane itself are presumed as causative factors. The authors report on six cases concerning this incidence. The indication for tympanoscopy and the technique for the closure of the round window fistula are reported. In 5 of the 6 patients treated in this manner, surgery the resulted in a significant and lasting hearing gain.
15年多来，圆窗膜破裂一直被认为是突发性感音神经性听力损失的一个可能原因。关于这种破裂的病理生理基础，推测蜗水管宽度异常以及圆窗膜本身的解剖变异是致病因素。作者报告了6例该发病率的病例。报告了鼓膜镜检查的适应症以及圆窗瘘管的封闭技术。用这种方式治疗的6例患者中有5例手术后听力显著且持久提高。
