Abstract
After a mean follow-up period of 7.3 years, a recurrence was found in 43 (12.3 per cent) out of 349 consecutive patients undergoing surgical treatment for acquired cholesteatoma. The great majority of residual cholesteatomas detected in the 'second-look' operations arose from the oval window area. Chronic otorrhoea and a reperforation were the most common signs of late recurrences. In eight ears a recurrent cholesteatoma developed from a retraction pocket. The recurrence rate was higher in children than in adults. The type of surgical technique had no significant effect on recurrence rate. Recurrences were more frequent in pre-operatively discharging ears than in dry ears. Some suggestions have been made to improve the results of surgery for cholesteatoma.
