Abstract: Objective: To discuss the clinical aspects and management of promontory fistula of the cochlear labyrinth.<br />Study Design: Case report and review of the literature.<br />Setting: University hospital, tertiary referral center.<br />Patient, Intervention, and Results: The authors describe an unusual case of cochlear fistula localized to the promontory discovered during tympanoplasty for noncholesteatomatous chronic otitis media in a 59-year-old woman. Bone conduction was slightly impaired after operation and hearing improved after a revision myringoplasty performed for reperforation.<br />Conclusion: Erosion of the bone of the labyrinth can also be observed in noncholesteatomatous otitis media. The presence of a fistula is not always associated with profound hearing loss. Overlying pathologic tissue can be removed without damaging the membranous labyrinth.
