ABSTRACT

Cholesterol granuloma is an inflammatory tissue response occuring as the result of foreign body reaction. Cholesterol granuloma is frequently found in the middle ear and mastoid cavity in a variety of chronic ear disease. It is a rare finding that cholesterol granuloma is found in the external ear canal. Most of cholesterol granulomas do not cause the destructive change of bony structure in the temporal bone. We experienced a case of cholesterol granuloma presenting as external ear canal mass destroying the posterior canal wall and mastoid tip.
