What Researchers Did
Researchers conducted a prospective study to evaluate the impact of hyperbaric oxygen therapy on the success of implant-retained lower dentures in 26 head and neck cancer patients who had received radiotherapy.
What They Found
In the hyperbaric oxygen therapy (HBO) group, 8 implants were lost, resulting in an 85.2% survival rate, compared to 3 implants lost and a 93.9% survival rate in the non-HBO group. Peri-implant tissues appeared healthy in both groups, and all patients reported good function with their dentures, with comparable improvements in quality of life. One patient in the HBO group developed osteoradionecrosis.
What This Means for Canadian Patients
This study suggests that hyperbaric oxygen therapy may not offer a significant advantage in improving implant survival or oral function for Canadian head and neck cancer patients undergoing rehabilitation with implant-retained dentures after radiotherapy. Patients and clinicians should carefully consider the potential benefits versus risks, such as osteoradionecrosis, when deciding on HBO for this specific treatment.
Canadian Relevance
This study has no direct Canadian connection.
Study Limitations
A limitation of this study is its relatively small sample size of 26 patients, which may limit the generalizability of the findings.
