Fibrous dysplasia is a benign fibro-osseous lesion of unkown etilogy. It is said that it may affect only a single bone (monostotic), or it may be present in, two or more bones (polyostotic). The disease is generally encountered in childhood or early adulthood. It grows very slowly. We recently experienced a case where this disease broke out in the right craniofacial region. A patient, a 63-year-old woman, complained of swelling in the right mandibular body at our hospital on February 25, 1983. Under the diagnosis of fibrous dysplasia, an incision was made from the second premolar to the second molar. The mucoperiosteal flap was retracted and the exposed buccal bone removed. The area was curetted, and the flap was returned and sutured in place. The histo-pathological examination of the specimens showed findings of fibrous dysplasia. Fourteen months have passed since the operation and the prognosis is favorable without any relapse tendency.
