초록
A higher residual rates after surgery have been reported in patients with congenital cholesteatoma than those with acquired cholesteatoma. The aim of this study was to document the risk factors of residual cholesteatoma after surgery for congenital cholesteatoma. Subjects and Method：From 1989 to 2006, 90 patients with congenital cholesteatoma treated at the Department of Otorhinolaryngology, Seoul National University Hospital were investigated retrospectively. Data were analyzed according to the location, type, stage, ossicular involvement, and initial surgery types for residual cholesteatoma. Results：Residual cholesteatoma was detected in 18.9% (17/90) of total patients. With respect to residual cholesteatoma, significant risk factors were found with the open type, mastoid involvement and stapes supra-structure erosion. On the other hand, location, initial surgery types did not show statistical significance. Conclusion：The Staged 2nd look operation should be performed for patients with congenital cholesteatoma, especially in either case of the open type, advanced stage or in the presence of supra-structure erosion.
