Abstract:

The osteoradionecrosis (ORN) is a severe, disabling complication caused by radiological exposure of vital bone in patients previously diagnosed with malignant tumors in the maxillofacial region. The treatment of osteoradionecrosis is defined for every clinical stage. The question about the prognosis and the prediction of progression is still open, although there is an adherence to the therapy protocols. The aim of the current review is to summarize the current literature data and to suggest a novel classification and staging system of the osteoradionecrosis. Accurate staging of the ORN is mandatory for the correct treatment plan and management, as well as for the prognosis and follow up. In spite of the great efforts, osteoradionecrosis stays one the most difficult conditions to overcome. It is possible to temporary stop the condition but the prognosis remains poor.
