Between November 1987 and April 1996, 110 cases with middle ear cholesteatoma were operated on in Kagawa Medical University Hospital. Seventy-three cases (66%) were followed more than 5 years after surgery with the average duration of 90 months (60 to 150 months).<BR>Surgical procedures were classified according to surgical methods and approaches in tympanoplasty for chronic otitis media 2000 proposed by the Organizing Committee of Otology Japan. Thirteen-three cases were operated on by canal wall up tympanoplasty, and 60 cases by canal wall down tympanoplasty. Twentyone cases of them underwent staged tympanoplasty. Type I tympanoplasty was performed in 6 ears, type II tympanoplasty 1 ear, type III tympanoplasty 2 ears, modified type III 49 ears, and modified type IV 15 ears.<BR>We evaluated the successful rate of hearing on 12 months and 60 months after surgery to investigate the change of the hearing level. The successful rate with modified type III tympanoplasty was stable for a longterm follow up. The successful rate with modified type IV tympanoplasty, however, was decreased 60 months after the surgery.<BR>Recurrent cholesteatoma occurred in 5 ears of canal wall up tympanoplasty (31%), 3 ears of canal wall down with canal reconstruction and mastoid obliteration (21.4%) and one ear of canal wall down tympanoplasty (2%). The recurrence rate in children (33.3%) was significantly higher than that in adult (6.9%). Mastoid obliteration was a useful method to prevent the postoperative cavity problem.
