Fibroma ossificante juvenil em mandíbula: relato de caso

Abstract

Ossifying Fibroma is a benign lesion of the jaws, well delimited, slow growing, asymptomatic and expressing a proliferation of fibrous cellular tissue with an amount of mineralized material. The mandible is the most affected region, it has female predilection, occurring in the third and fourth decades of life. Fibroma Ossificante Juvenil is a variation of this lesion, which affects young patients, no significant sex predilection and usually occurs in the maxilla. It has a more aggressive clinical behavior with a high relapse rate. In this work, we present a clinical case of juvenile ossifying fibroma in a female patient, 14 years old, was complaining about of a rapidly growing asymptomatic volumetric increase in the left jaw region with an evolution of approximately seven months. The treatment of choice was partial resection of the mandible and posterior reconstruction with autogenous iliac crest grafting, associated with hyperbaric oxygen therapy.
