title: Acquired cholesteatoma in adults.
abstract: The objectives of cholesteatoma surgery are to obtain a safe, dry, hearing ear. Controversies in regard to accomplishing these objectives center on indications for staging the operation and management of the mastoid using either a canal-wall-up or canal-wall-down procedure. The author discusses in detail the indications for each procedure.
