Three cases of congenital cholesteatoma associated with cholesterol granuloma

Abstract

Congenital cholesteatoma sometimes escapes detection because of its silent growth. We report threecases of children who had congenital cholesteatoma associated with cholesterol granuloma. Two of them hadbeen treated as otitis media with effusion before detection of congenital cholesteatoma. In the third case, unilateralhearing loss was found by school screening audiogram.
Congenital cholesteatomas grow slowly, but potentially disturb the middle ear ventilation. It might leadto otitis media with effusion and furthermore to cholesterol granuloma.
Clinicians must be aware of congenital cholesteatoma, and cholesterol granuloma in a case of persistentotitis media with effusion.
