Perilymphatic fistula occurs in a patient after various trauma-lifting, straining, coughing of other vigorous activities, barotrauma, stapedectomy, and perilymphatic hypertension etc. Traumatic perilymphatic fistula is found frequently in round window, oval window or both, whereas in general perilymphatic fistula is found mostly in lateral semicircular canal. Hearing loss following activities is thought to be an indication for surgical exploration. Perilymphatic fistula is grafted with bone chips, periosteum, cartilage, perichondrium, bone paste, musculoperiosteal flap, gelfoam, fat or fascia etc. On April 18, 1991, we experienced a case of traumatic perilymphatic fistula by umbrella's rod in a 42 year old female. Perilymphatic fistula was grafted with blood clot and musculoadipose tissue around oval window. And perforated tympanic membrane was grafted with deep temporalis fascia.
