What Researchers Did
This retrospective study compared surgical outcomes in patients with advanced mandibular osteoradionecrosis (MORN) who received hyperbaric oxygen therapy (HBOT) before and after surgery with those who did not.
What They Found
The study included 311 patients with MORN, 131 of whom received HBOT. Researchers found no significant differences in postoperative complications between the HBOT and non-HBOT groups, with similar rates for complete flap failure (HBO=4, non-HBO=2), nonunion (HBO=10, non-HBO=14), and wound infections treated surgically (HBO=2, non-HBO=7).
What This Means for Canadian Patients
For Canadian patients undergoing surgery for advanced mandibular osteoradionecrosis, this study suggests that adding hyperbaric oxygen therapy may not reduce common surgical complications like flap failure or infections. Patients should discuss all treatment options and potential benefits with their healthcare providers, understanding that current evidence does not strongly support HBOT for improving these specific surgical outcomes in MORN.
Canadian Relevance
No direct Canadian connection identified.
Study Limitations
This study was limited by its retrospective design and being conducted at a single academic center, which may affect the generalizability of its findings.
