We have treated five patients with fibrous dysplasia in the paranasal sinuses for ten years. There were one male and four females of 11-64 years old. In all patients, operation was performed and diagnosis of monostotic fibrous dysplasia was made from surgical specimens. Blood testing showed no abnormal data. CT of the paranasal sinuses revealed a diffuse high density mass in four cases and a cystic mixed density mass in one.RI scintigraphy was performed in four cases and showed abnormal 99mTC-DTPA accumulation in all patients and no 67Ga accumulation in one patient. So, CT and 99mTC scintigraphy were useful for regional diagnosis. In the surgical therapy we chose the total resection in one patient and partial resection in four patients. As to post-operative courses, cosmetic and functional problems were not encountered, but tumor enlargement was found in two cases which was performed partial resection. Patients, age, region and size of the tumor should be considered when we choose a surgical method. Careful postoperative observations is mandatory for a long time.
