Nonossifying Fibroma in the Mandible - A Case Report

Abstract

Nonossifying fibroma usually occurs in the long bones of young people and is rarely seen in the other areas of the skeleton. A nonossifying fibroma in the mandible of a 27-year-old woman is described in this report. This patient had an asymptomatic swelling at the left mandibular angle for 5 years. The swelling enlarged abruptly with accompanying severe pain and tenderness due to contusion over her left cheek 5 days before this admission. Skull radiographs and computed tomographic scans revealed a large multilocular and well-demarcated radiolucent lesion at the left mandible. The lesion was removed by segmental resection of the mandible with immediate reconstruction using a free vascularized fibular bone graft. The final pathologic diagnosis was nonossifying fibroma. The postoperative course was smooth and the occlusion was good. Follow-up radiographs showed no evidence of recurrence and good union of the graft 10 months after surgery.
