Abstract

BACKGROUND AND OBJECTIVE
It is not uncommon to encounter labyrinthine fistulae during cholesteatoma surgeries. The aim of this study is to evaluate the postoperative changes of labyrinthine fistulae after removal of matrix and closure by bone pate with fibrin glue.
MATERIALS AND METHODS
We evaluated 25 patients who had operatively closed labyrinthine fistulae of horizontal semicircular canal in the chronic otitis media with cholesteatoma using CT. Seven human temporal bones with labyrinthine fistulae were studied. The fistulae were closed with bone pate using fibrin glue and fascia.
RESULTS
Postoperative CTs show that, in all cases, the layer closing the fistulae was indistinguishable from the surrounding bony otic capsule.
CONCLUSIONS
Canal down mastoidectomy with closure of fistulae using bone pate with fascia were effective for new bone formation at the fistulae site.
