Abstract
We evaluated surgical results for middle ear cholesteatoma in new cases treated between 1983 and 1992. Hearing improved in 131 of 211 (62%) ears treated by single stage tympanoplasty and 22 of 48 (45.8%) ears treated by two-stage tympanoplasty. Better results were shown after single stage tympanoplasty. These results were associated with pathological deficits of the stapes. In the two-stage tympanoplasty group, supperstructural defects of the stapes were observed in 21 ears and footplate defects of the stapes in 7 ears.The closed method was performed in 84.5% of all cases; Residual cholesteatoma w as found in 3.0% during single stage tympanoplasty and 6.3% during two-stage tympanoplasty. The incidence of recurrent cholesteatoma was 8.5% after single stage tympanoplasty and 14.6% after two-stage tympanoplasty. Since two-stage tympanoplasty was used in children and advanced cases, surgical results may have been poorer.
