Experimental mandibular osteomyelitis: therapeutic trials with hyperbaric oxygen
Summary
Hyperbaric oxygen therapy (HBO) improved healing in rabbit mandibular osteomyelitis, showing better bone repair and reduced fracture site mobility. While not eliminating infection, HBO therapy offers significant benefits for this condition.
Area of Science:
- Oral and Maxillofacial Surgery
- Orthopedic Surgery
- Infectious Diseases
Background:
- Mandibular osteomyelitis is a challenging condition.
- Hyperbaric oxygen (HBO) therapy shows promise for osteomyelitis treatment.
- Previous controlled studies focused on long bone osteomyelitis.
Purpose of the Study:
- To investigate the efficacy of HBO therapy in a rabbit model of mandibular osteomyelitis.
- To assess the impact of HBO on osseous repair and sinus tract healing.
Main Methods:
- Osteomyelitis was induced in rabbit mandibles using Bacteroides melaninogenicus.
- Animals were randomly assigned to HBO treatment (2 atmospheres for 2 hours daily for 40 days) or ambient air control.
- Outcomes included bacterial cultures, fracture site inspection, and mobility assessment.
Main Results:
- HBO therapy did not eradicate chronic osteomyelitis.
- Significant improvements were observed in sinus tract healing and osseous repair in the HBO group.
- Diminished mobility at the fracture site was noted in animals receiving HBO.
Conclusions:
- Hyperbaric oxygen therapy demonstrates therapeutic benefits for mandibular osteomyelitis in rabbits.
- HBO promotes healing and reduces instability in infected mandibular fractures.
- Further research may explore HBO as an adjunct treatment for similar human conditions.
