title: Cochlear fistula in a noncholesteatomatous ear.
abstract: Bony destruction of the labyrinth is usually associated with long-standing cholesteatomatous otitis media. The promontory is not a common site for bone resorption because (1) it is not an area that is involved in accumulation of cholesteatoma perimatrix substances, (2) it is the densest bone of the human body, and (3) pressure necrosis from overlying tissue is uncommon. We report a case of cochlear erosion associated with noncholesteatomatous middle ear disease. As far as we know, this is only the second such case reported in the literature. We also review decision-making factors and techniques for the safe management of this condition.
