I have a case and in need of your advise and expert opinion. I have a patient who just underwent treatment for throat cancer back in June of 2020. His oncologist is concerned about osteoradionecrosis of the mandible. In your opinion what are the guide lines for timing of implant placement in maxilla and mandible in a patient who went through radiation and chemotherapy for throat cancer? Looking forward to your responses. Thankyou.

The maxilla is normally not an issue in such situations. The mandible is at risk for ORN and treatment is best avoided. If you were to proceed, hyperbaric oxygen would be advised(Marx protocol).At the time of surgery minimal tissue elevation should be undertaken. Of course, you would also want to know that the patient’s blood work is in order in addition to determining which chemotherapeutic agents had been used. It is unlikely that bisphosphonates were administered but there are also so newer anti-angiogenic medications which have been associated with implant complications.
