This article presents 6 cases with idiopathic perilymph fistulae. The etiology of idiopathic perilymph fistula may be congenital malformation of the otic capule. Diagnosis of idiopathic perilymph fistula primarily depends on history and exploratory tympanotomy, but ENG-fistula test and positional audiometry are worth of diagnosing. During microsurgical procedure, attention must be paid to the presence of membrane of the round window niche. If a good repair of fistula is not followed by a good result, other lesions such as double labyrinth membrane rupture should be considered.
本文介绍了6例特发性外淋巴瘘患者。特发性外淋巴瘘的病因可能是耳囊的先天性畸形。特发性外淋巴瘘的诊断主要依靠病史和探查性鼓室切开术，但ENG瘘管试验和位置性听力测定也有助于诊断。在显微手术过程中，必须注意圆窗龛膜的存在。如果瘘管修复良好但效果不佳，应考虑其他病变，如双迷路膜破裂。
