A patient previously irradiated for oropharyngeal cancer has exposed mandibular bone, pain and a pathological fracture without recurrent tumour. What management principle is most appropriate?
A pathological fracture indicates advanced osteoradionecrosis. Infection control, nutrition, dental assessment and exclusion of recurrence are necessary, but major resection and vascularised reconstruction may be required.
A. Repeated antibiotics alone indefinitely: Antibiotics do not remove devitalised fractured bone.
B. Immediate radiotherapy: Further radiation worsens tissue injury and is not treatment for necrosis.
C. Ignore the fracture if biopsy is negative: Mechanical instability and necrosis still require management.
D. Stage the osteoradionecrosis and plan specialist debridement or resection with reconstruction for advanced disease: A pathological fracture indicates advanced osteoradionecrosis. Infection control, nutrition, dental assessment and exclusion of recurrence are necessary, but major resection and vascularised reconstruction may be required.
E. Extract all teeth without planning: Unplanned dental trauma can worsen radionecrosis.
If disease were limited superficial exposed bone without fracture, conservative measures and limited debridement might be considered first.
