Abstract

© 2021 The British Association of Oral and Maxillofacial SurgeonsPatients with osteoradionecrosis (ORN) of the mandible pose additional challenges to the attending clinician when it comes to major reconstructive head and neck surgery. We present a novel technique to assist in the virtual surgical planning of mandibular ORN, which involves deforming previously delivered radiation dosimetry data on to the virtual mandible to aid in the assessment of surgical resection margins. This is a retrospective case series of patients whose treatment involved a traditional virtual surgical planning approach or dosimetry-guided virtual surgical planning. All the patients whose treatment involved dosimetry-guided virtual surgical planning had evidence of bony consolidation between the native mandible and fibular free flap. In comparison, only three of the nine patients in the traditional virtual surgical planning group demonstrated bony healing on subsequent imaging. In this known cohort of difficult-to-manage patients, any technique that helps to improve outcomes is a welcome addition to the armamentarium of the surgeon.
