Abstract
Twenty-two ears of residual cholesteatomas, which were found in 81 cases undergoing revised surgery, were analyzed.
1. The residues were found in 20% of the PF (Pars flaccida) type cholesteatomas, while they were found in 53% of the PSQ (posterior-superior quadrant) type.
2. In 67% of the total residues, the 2-dimensional size of the residues were less than 1 quarter of the tympanic membrane.
3. In the PSQ type, the residues were most frequently found in the stapes foot plate area.
4. The residues of the child cases were larger than those observed in the adult cases.
5. The wet cases tended to result in the presence of a large residue.
