What Researchers Did
Researchers retrospectively analyzed the use of hyperbaric oxygen therapy in 21 patients with radionecrosis of the head and neck at the University of Virginia.
What They Found
The study included 16 patients with osteoradionecrosis and 5 with chondroradionecrosis, all of whom showed clinical improvement and decreased pain after hyperbaric oxygen therapy. Notably, none of the chondroradionecrosis patients required laryngectomies, and two of four tracheotomy-dependent patients were successfully decannulated. Both patient and physician grading scores indicated moderate to significant improvement in both groups.
Canadian Relevance
This study has no direct Canadian connection as it was conducted at the University of Virginia.
Study Limitations
A limitation of this study is its retrospective design, small sample size of 21 patients, and lack of a control group, which limits the generalizability of the findings.
