Cholesteatoma in children is well known to be more expansive than in adults. To remove cholesteatoma in children with closed technique is very difficult, but in open technique there are more often cavity problems than in adults. In this paper 38 ears with cholesteatoma were reviewed. These ears were operated on from 1987 to 1995 and followed up for more than two years. The mean follow-up periods were 63.8 months (with a range of24 to 126 months).

A one-stage operation was performed in 8 ears and two or more stage operations in 30 ears. Residual cholesteatoma was found in 20 ears (66.7%) in the second stage operation. In the first operation closed technique was performed in 21 ears, canal down and reconstruction technique in 15 ears, open technique in one ear and open technique with partial mastoid obliteration in one ear. In the final operation closed technique was performed in 16 ears, canal down and reconstruction in 9 ears, open technique in 5 ears, open technique with partial mastoid obliteration in 3 ears and total mastoid obliteration in 5 ears.

The mean postoperative air conduction hearing level was within 20dB in 6 ears, within 30dB in 17 ears and within 40dB in 28 ears. Recurrent cholesteatoma was found in 4 out of7 ears with one stage and closed technique, and in 2 out of 29 ears with two or more stage operation and closed or canal reconstruction technique.
