Hyperbaric Oxygen Therapy as an Adjunct for Treating an Individual with Poorly Healing Bilateral Mandibular Fractures Suspect of Developing Towards Osteomyelitis: A Case Report and Clinical Experience.

Purpose: To present a case that benefited from utilizing hyperbaric oxygen therapy in conjunction with antibiotics for a non-healing mandibular fracture that was highly suspicious of osteomyelitis. Also, to discuss research set forth by Undersea and Hyperbaric Medical Society that supports the use hyperbaric oxygen in such cases.

Case: A 25-year-old male status post fist to face resulting in bilateral mandibular fracture. He underwent two surgeries in an attempt to plate the fracture with the assistance of a bone graft. After failure of the bone graft and significant soft tissue wound breakdown, the surgeon was concerned for osteomyelitis and began therapy with intravenous antibiotics and hyperbaric oxygen therapy.

Conclusion: The patient completed 30 hyperbaric oxygen treatments and 30 d of intravenous antibiotics. Clinically, the patient responded well and showed healed intraoral wounds and an objective decrease in erythrocyte sedimentation rate over the course of treatment. Unfortunately, on serial imaging the patient showed to have fibrous non-bony union of left fracture site. Even though the patient will need a final definitive plate for his fracture, it will be performed from an extraoral approach with no evidence of underlying infection.
