What Researchers Did
Researchers conducted a narrative review of the literature to update clinicians on the risk of osteoradionecrosis (ORN) associated with oral surgery in head and neck radiotherapy patients, focusing on suitable timing and possible preventive treatments.
What They Found
They found that osteoradionecrosis (ORN) is a serious complication of head and neck radiotherapy, often triggered by dental extractions, and a pre-radiotherapy dental visit is highly recommended to minimize future extractions. Proposed post-radiotherapy preventive strategies for dento-alveolar surgery include antibiotics, hyperbaric oxygen (HBO), and the "PENTO protocol" (pentoxifylline and tocopherol), though established standards of care are currently lacking.
What This Means for Canadian Patients
Canadian patients undergoing head and neck radiotherapy should prioritize a comprehensive dental evaluation before treatment to reduce the risk of osteoradionecrosis (ORN) from future dental extractions. If oral surgery is necessary after radiotherapy, patients should discuss proposed preventive strategies, such as antibiotics or specific drug protocols, with their multidisciplinary care team, understanding that standard protocols are still evolving.
Canadian Relevance
This study has no specific Canadian connection.
Study Limitations
As a narrative review, this study may not have systematically synthesized all available evidence, potentially leading to selection bias.
