Five hundred fifty ears with chronic otitis media were treated surgically at our hospital between 1981 and 1990. They consisted of 313 ears with cholesteatoma and 237 ears without cholesteatoma. The former affected men more often than women, especially in children. Tympanoplasty type I was most frequently performed, and type III-C was the second choice. Surgery for recurrence of cholesteatoma was required in 19.8% of all cholesteatoma cases.10.2% of the cholesteatomas were caused by a tympanoplasty. Tympanoplasty type I was successful in 73%, type II in 50%, type III in 44%, Type III -C in 62%, type IV in 18% and type IV-C in 37%.
