title: Management of labyrinthine fistula in middle ear cholesteatoma.
abstract: Labyrinthine fistula is a complication of chronic otitis media with cholesteatoma. Canal wall down tympanoplasty with partial mastoid cavity obliteration and complete removal of cholesteatoma matrix was adopted in five cases of labyrinthine fistula. The operation resulted in elimination of vertigo. Sensory hearing has been saved in two cases. Air conduction hearing improved in one case. In three cases whose air conduction deteriorated post-operatively, bone conduction worsened in two cases and remained unchanged in one case (Tympanoplasty type 0 was performed in the other one case.) During the follow-up period, otorrhea improved in all cases and there was no evidence of recurrence of cholesteatoma. If the hearing of the other ear is acceptable, we suggest one-stage canal wall down tympanoplasty with complete removal of cholesteatoma matrix and partial mastoid cavity obliteration. It provides low recurrence rate of cholesteatoma and there is no need of re-operation.
