Abstract
Congenital fistula in the stapedial footplate usually can be diagnosed by the recurrence of meningitis caused by spontaneous cerebrospinal fluid (CSF) in infants or young children. We report the case of a 65-year-old woman, who was initially diagnosed as having an acquired perilymphatic fistula caused by aural barotrauma and demonstrated episodic vertigo and fluctuant sensorineural hearing loss in the right ear after air travel. Surgical exploration showed a congenital circular defect in the peripheral part of the stapedial footplate with leakage of CSF. The fistula was closed by inserting a tiny piece of fascia attached to both the tympanic and perilymphatic side of the stapedial footplate utilizing the back-pressure of perilymphatic fluid and fibrin glue; hearing was preserved.
