What Researchers Did
A researcher performed a systematic meta-analysis of studies on treating osteoradionecrosis (ORN) of the jaw, bone death caused by radiation therapy, comparing HBOT alone, surgery alone, and the combination of both.
What They Found
The combination of HBO and surgery had a 69% success rate (95% CI: 47-85%), significantly outperforming either HBOT alone (38% success) or surgery alone (36% success). The difference between combination therapy and each individual approach was statistically significant (p = 0.015 for HBOT vs. combination; p = 0.008 for surgery vs. combination). HBOT alone and surgery alone performed similarly to each other.
What This Means for Canadian Patients
For Canadians who develop jaw bone damage after radiation therapy for head and neck cancer, a condition that can cause severe pain, infection, and jaw fractures, the evidence strongly favors combining HBOT with surgery over using either treatment on its own. Patients should ask their oncologist or oral surgeon about combined treatment planning.
Canadian Relevance
Osteoradionecrosis (mandibular radiation injury) is an OHIP-covered indication for HBOT in Ontario; this meta-analysis directly supports that coverage with quantified success rates.
Study Limitations
The included studies had varied definitions of treatment success and different HBOT protocols, which limits the precision of the pooled estimates.
