Cholesterol granuloma of the maxillary sinus.

Cholesterol granuloma is usually associated with middle ear disease and is very rare in the paranasal sinuses. We report a case of cholesterol granuloma originating in the maxillary sinus of a 36-year-old female. Endoscopic sinus surgery was performed on the left maxillary, sinus, and the cholesterol granuloma was successfully removed by the middle meatal antrostomy.
