Abstract
- Congenital cholesteatoma of the middle ear classically presents as a white retrotympanic middle ear mass. In spite of many theories on congenital cholesteatoma, its pathogenesis is still unclear. There are two distinct pathologic types of congenital cholesteatoma, closed and open type. The closed cystic form can be easily removed, but the open type has a tendency to make strong contact with the middle ear mucosa and to infiltrate into the surrounding structures. We report a rare case which presented both open and closed types of congenital cholesteatoma.
