91例明显存在外淋巴瘘的患者表现出一系列令人惊讶的体征和症状，从单侧耳鸣和耳闷到突发性极重度听力损失、咆哮性耳鸣和旋转性眩晕。1977 ~ 1984年间，对177例疑有外淋巴瘘（PLF）的患者行214次鼓室探查术。在95耳中发现了106例原发（初始）瘘管，并确定了26例复发瘘管。91例PLF患者中有82%有听觉症状，8%的患者以听觉症状为唯一主诉。81%的患者有前庭症状，12%的患者仅有前庭症状。听力损失的类型和前庭症状的性质有很大的差异。在58例术前有听觉症状的患者中，49%的患者在PLF闭合后听力改善（23%改善至可用范围）。95%出现前庭症状的患者的头晕症状消除或减轻，不再干扰他们的日常活动。瘘复发率最高的是使用脂肪组织的移植物。Mondini畸形患者瘘管复发的风险特别高。
Ninety‐one patients with demonstrable perilymph fistulas presented with an amazing array of signs and symptoms ranging from unilateral tinnitus and aural fullness to sudden‐and‐profound hearing loss, roaring tinnitus, and whirling vertigo. Between 1977 and 1984, 214 exploratory tympanotomies for suspected perilymph fistula (PLF) were performed on 177 patients. One hundred six primary (initial) fistulas were found in 95 ears and 26 recurrent fistulas were identified. Eighty‐two percent of the 91 patients with PLF had auditory symptoms, 8% with auditory symptoms as the sole complaint. Eighty‐one percent of the patients had vestibular symptoms, 12% with vestibular symptoms alone. The type of hearing loss and the nature of the vestibular symptoms were widely variable. Of the 58 patients with preoperative auditory symptoms, 49% had improved hearing (23% improved to serviceable range), after closure of PLFs. Ninety‐five percent of the patients who presented with vestibular symptoms had elimination of or decrease in their dizziness to the extent that it no longer interfered with their daily activities. The highest incidence of recurrent fistula was associated with grafts using fatty tissue. Patients with Mondini deformity were at particularly high risk for fistula recurrence.
