Perilymph Fistulas Secondary to Gunshot Wound

Abstract
• The symptoms, clinical evaluation, routes of formation, and repair of perilymph fistulas are reviewed. We report a case with oval and round window perilymph fistulas secondary to a gunshot wound. A radioactive pharmaceutical was injected into the subarachnoid space in the lumbar area. Subsequent radioactivity was detected at the sites of the fistulas. We discuss the implications and a suggested technique for fistula detection. (Arch Otolaryngol 103:98-102, 1977)
