Oral Surgery · single question

A patient with a history of head/neck radiation therapy 10 years ago needs several extractions. What is the most appropriate approach?

  1. Proceed with extractions exactly as you would for any other patient
  2. Obtain medical consultation (with the radiation oncologist/treating physician) before proceeding, given the lifelong risk of osteoradionecrosis in irradiated bone
  3. Refer the patient out permanently and decline to ever provide dental care
  4. Premedicate with antibiotics only and proceed without any consultation
Show answer and explanation

Correct answer: B. Obtain medical consultation (with the radiation oncologist/treating physician) before proceeding, given the lifelong risk of osteoradionecrosis in irradiated bone

Irradiated bone carries a lifelong risk of osteoradionecrosis (ORN) after extractions, especially within the radiation field, because radiation impairs bone vascularity and healing capacity indefinitely — this risk does not diminish much over time. Medical consultation, sometimes with consideration of hyperbaric oxygen therapy or modified surgical technique, is appropriate before extracting teeth in a previously irradiated field.
