Effective canal wall down mastoid surgery requires attention to certain key principles. We reviewed all cases requiring revision surgery at the Royal Victoria Eye and Ear Hospital over a 6 year period 1999-2004. Intraoperative findings which contributed to the need for revision surgery were identified. During this 6 year period 291 canal wall down mastoidectomies were performed. Thirty-seven were revision procedures. Nineteen (51%) cases were found to have recurrent or residual cholesteatoma. Sixteen (43%) cases had a high facial ridge, thirteen (35%) cases had an open middle ear. Nine (24%) cases had an inadequate meatus, 2 (5%) cases had a cavity sump. This study illustrated that a high facial ridge, an open middle ear segment, an inadequate meatoplasty and recurrent cholesteatoma were common intraoperative findings in this revision group. Eighty-nine percent of revision cases had dry, healed and safe cavities on follow up. Poor performance of the open technique is the most important factor in failure.
