The rupture of the round window membrane with consecutive perilymph fistula has gained in importance in the discussion of the pathogenesis of sudden hearing loss. In a retrospective study, the results of 23 tympanoscopies performed at the ENT Department of the University of Hamburg are reported. Two confirmed perilymph fistulas were seen, whereas in three cases they could not be excluded. After obliteration of the window niches with connective tissue an improvement of the hearing loss was seen in 9 cases. In comparison with our intraoperative findings, the number of perilymphatic fistulas mentioned in literature often seems very high. Nevertheless, tympanoscopy and obliteration of the window niches have their definite place in the therapeutic concept of sudden hearing loss, although the indication must be severely restricted.
圆窗膜破裂伴发连续性外淋巴瘘在突发性听力损失发病机制的讨论中愈发重要。在一项回顾性研究中，报告了汉堡大学耳鼻喉科进行的23例鼓膜镜检查结果。发现2例确诊的外淋巴瘘，而有3例不能排除存在外淋巴瘘。在用结缔组织封闭窗龛后，9例患者的听力损失有所改善。与我们的术中发现相比，文献中提及的外淋巴瘘数量似乎常常非常多。然而，鼓膜镜检查和封闭窗龛在突发性听力损失的治疗理念中确有其明确的地位，尽管适应证必须严格限制。
