What Researchers Did
This review article discussed the pathophysiology, risk factors, prevention, and treatment of osteoradionecrosis (ORN), a severe complication of radiation therapy for head and neck cancer.
What They Found
They found that ORN is theorized to be radiation-induced fibroatrophy, with key risk factors including primary tumor location, cancer stage, radiation dose, oral hygiene, and smoking and alcohol use. Prevention focuses on thorough dental care before, during, and after radiation therapy, while treatment options range from conservative management with oral rinses to radical resection with microvascular free tissue transfer.
What This Means for Canadian Patients
Canadian patients receiving radiation for head and neck cancer should prioritize comprehensive dental care to mitigate the risk of osteoradionecrosis. If ORN develops, a variety of treatment approaches, from conservative to surgical, are available to manage this condition.
