Abstract
Surgical treatment of middle ear cholesteatoma was evaluated from the point of postoperative hearing and recurrence of cholesteatoma. Of the 36 ears operated on in the previous 5 years and 5 months, intact canal wall tympanoplasty was performed in 27 ears, and tympanoplasty with posterior canal wall removal in 9 ears. The patients were evaluated for a follow-up period of more than 6 months after tympanoplasty. The rate of success in hearing improvement was 82.4% according to the criteria of the Japan Otological Society. Recurrence of the cholesteatoma was found in 2 ears (5.6%), which had been treated by intact canal wall tympanoplasty. A retraction pocket in the attic was found in 5 ears (17.9%), following intact canal wall tympanoplasty. Reconstruction of the attic defect with cartilage and obliteration of the mastoid cavity were useful in the prevention of postoperative retraction pocket.
