Abstract

The estimated incidence of recurrent or residual cholesteatoma requiring revision mastoid surgery ranges from 2% to 10% in canal wall down mastoidectomy. The causes of failure of mastoidectomy include recurrent cholesteatoma, suppuration in unexentrated cells, and mechanical factors promoting retention of debris within the mastoid cavity. The authors have experienced a case of long-term residual cholesteatoma, without connection to the previous radical mastoidectomized cavity, which showing subscalp fistula and extradural granulation with continuous purulent discharge. So we report with a review of literature.
