Seventy-eight tympanotomies were performed to determine the presence of perilymph fistulas (PLFs); of these, 51% were found. The oval and round windows of all patients were grafted, whether PLFs were present or not. Of those patients with PLFs, 64% had resolution of their major symptom; when no PLF was found, 44% had a similar outcome. We concluded that 1) PLFs often behave as if they are epiphenomena in relation to hearing and balance, 2) PLFs can be intermittent, 3) PLF surgery is disappointing for restoration of hearing in sudden hearing loss when compared to the rate of spontaneous recovery, 4) stabilizing a fluctuating or progressive loss is a more realistic goal, and 5) establishing preoperative criteria for exploration is still a problem.
进行了78次鼓室切开术以确定外淋巴瘘（PLF）的存在；其中，发现有外淋巴瘘的占51%。无论是否存在外淋巴瘘，所有患者的椭圆窗和圆窗均进行了移植。在有外淋巴瘘的患者中，64%的主要症状得到缓解；未发现外淋巴瘘的患者中，44%有类似结果。我们得出结论：1）外淋巴瘘在听力和平衡方面常表现为似乎是附带现象；2）外淋巴瘘可能是间歇性的；3）与自发恢复率相比，外淋巴瘘手术在突发性听力损失的听力恢复方面令人失望；4）稳定波动或进行性听力损失是一个更现实的目标；5）建立术前探查标准仍然是一个问题。
