Abstract
Fibrous dysplasia of bone is a benign disease characterized by the progressive replacement of normal bone elements by fibrous tissue. The disease can involve any bone in the body. However, involvement of the zygomatic arch is relatively rare. Moreover, depending on the site and extent, fibrous dysplasia may be accompanied by functional disorder. We report a case of fibrous dysplasia of the zygomatic arch that extended to the pterygoid fossa, producing trismus.A 56-year-old woman was referred to our hospital because of a painless swelling in the left cheek and trismus. Computed tomography and simple X-ray examinations of lesion revealed a ground-glass appearance. Biopsy was performed, leading to a suspected diagnosis of osteoma. The lesion interfered with the movement of the mandible. The lesion was resected under general anesthesia. The histopathological diagnosis was fibrous dysplasia. The postoperative course was uneventful, and the lesion has not recurred for 6 years.
