Objective: Osteoradionecrosis (ORN) is a severe and devastating late complication of radiotherapy in patients with head and neck cancer, especially in the mandible.

Methods: We report a case of a 47-year old woman who is suffering from osteoradionecrosis and bone exposure 5 years after irradiation therapy for squamous cell carcinoma (SCC) of the tongue. Segmented resection of the mandible was performed followed with reconstruction using a plate.

Results: ORN can cause a pathological fracture of the mandible and should be treat with a surgical approach.

Conclusion: ORN affects the mandible more often than the maxilla or any other bones of head and neck because it has high density and low blood vasculature that can cause pathological fracture of the mandible. Preventive measures must be evaluated to reduce the risk or severity of ORN
