[Labyrinth fistula in chronic otitis with cholesteatoma].
The authors studied 116 surgically treated patients with labyrinthine fistulae due to cholesteatoma. The fistulae were most commonly localized on the lateral semicircular canal (75%) and much less frequently involved only the oval window area (7%) and the promontory (4%). The multiple fistulae were found in 14% patients. The closed technique was used, while the open technique was adopted only when the ear was deaf preoperatively, in cases of multiple fistulae and associated intracranial complications. The cholesteatoma matrix was not removed from the fistula of the oval window area or the promontory or in the cases of multiple fistulae and large fistulae of the lateral semicircular canal if the cholesteatoma matrix had penetrated into the labyrinth. The fistulae on the lateral semicircular canal were covered by a piece of fascia. Postoperatively deafness occurred only very exceptionally.
