What Researchers Did
Researchers retrospectively reviewed charts of 40 patients who received head and neck radiation and underwent hyperbaric oxygen therapy before and after dental extractions to assess osteoradionecrosis incidence and identify risk factors.
What They Found
Immediately after hyperbaric oxygen therapy, the incidence of osteoradionecrosis was 0% among 40 patients. However, long-term follow-up (over six months) in 19 of these patients revealed the incidence of osteoradionecrosis increased to 15.8%. No significant risk factors for osteoradionecrosis development were identified.
What This Means for Canadian Patients
Canadian patients undergoing dental extractions after head and neck radiation therapy, even with hyperbaric oxygen treatment, should be aware of the potential for delayed osteoradionecrosis. Regular, long-term follow-up with their healthcare providers is important to detect and manage this complication, despite initial positive outcomes.
Canadian Relevance
This study has no direct Canadian connection as it was not conducted in Canada or with Canadian participants.
Study Limitations
Limitations include the retrospective design, the small sample size for long-term follow-up, and the inability to identify statistically significant risk factors.
