Abstract
A retrospective analysis has been conducted of 57 labyrinthine fistulae found in 375 cholesteatoma cases, primarily treated by removal of the matrix of the cholesteatoma and covering the fistula with a mixture of bone paste and fibrin glue. CT-scan with slices of 1 mm demonstrated the fistula in almost 90% of the cases. Eighteen percent of the ears were pre-operatively totally deaf. Large fistulae are riskier than smaller ones for post-operative perceptive losses, but even in very large and multiple fistulae the hearing may be preserved in most cases.
