Backgrounds and Objectives：Recently congenital cholesteatoma of middle ear has been diagnosed in earlier stage and its clinical manifestation has showed changed clinical manifestation, comparing that of reported literature. Aim of this study were to elucidate of clinical finding, extent of the cholesteatoma, staging, operative procedure and rate of postoperative recurrence in congenital middle ear cholesteatoma. Materials and Methods：47 cases of congenital cholesteatoma had been treated in Department of Otorhinolaryngolgy of Pusan National University Hospital from 1997 to October of 2010 and were reviewd retrospectively. Results：Congenital cholesteatoma showed male preponderance, and had diagnosed incidentaly (46.8%) and most common symptom was hearing loss. Most were found in tympanum only (70.2%) and more found in posterior portion than in anterior portion. Rate of each stage is similar distribution in stage I, II, III, IV. Recurrence rate showed 14.9%. Conclusions：Early diagnosis and early intervention is important to avoid recurrence and morbidity.
