Of the 38 ears operated on from 1978 to 1984 in this series, 71% required reoperation, 26% for revision and 3 % for a second look. Of the 27 reoperated ears, 89% had discharge preoperatively; 80% of them showed improvement postoperatively. Discharge was greatly reduced in 91.3% of the ears treated with the closed method. This figure is significantly higher than the 25% of those improved by the open method. Of the 27 reoperated ears, 48% were believed to have recurrence of cholesteatoma, and in 26% of these there was a disturbance of drainage. Although recurrence of cholesteatoma was found in 66.7% of the ears treated with revision or second look operations, discharge was reduced in all cases. These results indicate that ear surgery should be done by the closed method, especially revision or second look operations in cases of cholesteatoma.
