Fibro-osseous lesions of the jaws

Abstract

In the first volume of the Journal of Oral Surgery, Dr G. Victor Boyko presented a case of osteofibroma of the mandible associated with leontiasis ossea of the skull (Boyko GV: J Oral Surg 1:100, 1943). The patient was a 32-year-old white woman who had complaints of right mandibular enlargement and a prominence of the right frontal and temporal areas of uncertain duration in August 1939. Mandibular radiographs showed an area of reduced radiodensity. Skull films showed a marked increase in density of the inferior part of the right temporal region and of the frontal bone, with evidence of both bone destruction and proliferation in the inferior frontal and orbital regions. A mandibular biopsy was reported as osteofibroma. The patient was kept under observation for 8 months after the biopsy, with little change in her condition. A course of deep x-ray therapy was then delivered to the mandibular lesion. She subsequently developed a pathologic fracture that was treated by maxillomandibular fixation. The fracture stabilized and at the last clinical examination, in June 1942, the patient had a union with good functional occlusion and was reported to be in good mental and physical condition.
