abstract: The case of a residual aural cholesteatoma extending into the posterior cranial fossa after radical mastoidectomy is presented. The importance of distinguishing this lesion from primary cholesteatoma of the cerebellopontine angle is discussed. The safety of canal-wall-down procedures is also discussed.
