Osteoradionecrosis in a Patient Submitted to Head and Neck Radiotherapy: A Case Report

ABSTRACT: Radiotherapy applies ionizing radiation at predetermined doses for a limited period of time in order to destroy tumors. The oral cavity, which has a high rate of cell renewal, is affected by the side effects of radiotherapy including osteoradionecrosis (ORN). This condition occurs due to i...

The oral cavity, which has a high rate of cell renewal, is affected by the side effects of radiotherapy including osteoradionecrosis (ORN). This condition occurs due to irradiated bone tissue that becomes devitalized and exposed in the oral cavity. Conservative therapies are recommended for ORN lesions that are not extensive or in an early stage. Surgical intervention is necessary for extensive areas affected by necrosis. This study reports a case of ORN in the left mandibular body which resulted in a pathological fracture. The treatment consisted of segmental mandibulectomy and the use of a reconstruction plate. Also, low-level laser therapy around bone exposure was performed. After surgery, the patient underwent 6 months of follow-up and was satisfied with the outcome. However, the patient died before control of ORN was achieved due to a heart attack.info:eu-repo/semantics/openAccessUniversidad de La Frontera.
