Bilateral promontory fistula due to noncholesteatomatous chronic otitis media.
The authors describe a case of bilateral promontory fistula due to noncholesteatomatous chronic otitis media in a 46-year-old male. We performed both open cavity mastoidectomy and left staged ossiculoplasty. One year postoperatively, the audiogram showed an improved left air conduction threshold and maintenance of bone conduction. We suggest that noncholesteatomatous chronic otitis media can induce various destructive changes via the chronic inflammatory reaction.
