Mandibular osteoradionecrosis treated with platelets rich fibrin and Bichat fat pad: Case report

Abstract

Osteoradionecrosis is a severe oral complication that may affect patients undergoing radiotherapy for head and neck cancer. It is defined as an area of irradiated, exposed bone that does not heal for a period of three months, without any residual or recidivating tumor. The radiological aspects are nonspecific, with osteolytic areas and bone sequestra, thus resembling osteomyelitis or medication-related osteonecrosis. The diagnosis is based on the association of clinical and radiological findings. There is no treatment protocol established, and treatment can be conservative or surgical. The objective of this study was to report a case of osteoradionecrosis treated by bone sequestra removal associated with platelet-rich fibrin and Bichat's fat pad, in a 63-year-old female patient.
