Perilymphatic fistula is suspected on clinical symptoms, but must be confirmed by surgery. Exploratory tympanotomy was realized in 38 patients, presenting one or several symptoms of perilymphatic fistula. A leak was observed in 23 patients (61%). When a leak was not observed, the oval and round windows were filled with connective tissue. Preoperative and post-operative symptoms were compared in patients with or without leak: there was not significant difference between the two groups of patients. 63% of patients presenting fluctuant or sensorineural hearing loss improved or stabilized hearing after surgery. One patient, presenting a post-traumatic total deafness due to round window rupture, was immediately operated on, and recovered normal hearing. 84% of patients with vertigo or dizziness improved after surgery. The authors conclude that exploratory tympanotomy should be widely proposed when a perilymphatic fistula is suspected. Oval and round window should be grafted with connective tissue even if a leak is not observed.
根据临床症状怀疑存在外淋巴瘘，但必须通过手术确诊。对38例出现一种或多种外淋巴瘘症状的患者实施了探查性鼓室切开术。23例患者（61%）观察到有渗漏。当未观察到渗漏时，卵圆窗和圆窗充满结缔组织。对有或无渗漏患者的术前和术后症状进行了比较：两组患者之间无显著差异。63%出现波动性或感音神经性听力损失的患者术后听力得到改善或稳定。1例因圆窗破裂导致创伤后全聋的患者立即接受手术，听力恢复正常。84%患有眩晕或头晕的患者术后病情改善。作者得出结论，当怀疑存在外淋巴瘘时，应广泛建议实施探查性鼓室切开术。即使未观察到渗漏，也应对卵圆窗和圆窗进行结缔组织移植。
