Abstract
A case of polyostotic fibrous dysplasia of the maxilla and mandibula, seen in a 35-year-old female, was reported. The patient had a progressive swelling on the right side of her face with nasal stiffness during the past year. X-ray examination revealed a high density lesion in the right maxillary sinus. CT examination on the maxillary sinus disclosed a mass lesion that consisted of many irregular high density areas with expansive low density mass. A similar lesion was also seen in the mandibula. Fibrous dysplasia was diagnosed by histologic examination of the biopsy specimen that was taken from a mass in the maxillary sinus. Removal of the mass in the maxillary sinus was done. Four months after the surgery no sign of recurrence was observed.
