Cholesterol granuloma is a disease in which cholesterol crystals act as a foreign substance in the surrounding tissues and cause granulomatous reaction and fibrosis within the chamber. It is found in various locations of the body, but the most common location is the temporal bone associated with middle ear disease. Because the disease is associated with breathing disturbance, it may also occur in the paranasal sinus. However, it has been rarely reported since its first report by Graham and Michaels in 1978. Recently, we experienced a case of cholesterol granuloma of the right maxillary sinus of a 63-year-old female patient without any nasal symptoms. We successfully managed this case with Caldwell-Luc operation. Also, we summarized the cases of cholesterol granuloma of the sinonasal region reported in Korea.
