What Researchers Did
Doctors in the United States reported the case of a 61-year-old woman with cancer undergoing chemotherapy who developed jaw osteomyelitis caused by Actinomyces bacteria, and was treated with antibiotics and HBOT.
What They Found
The patient presented with jaw pain and white spots on the mandible that were initially confused with other conditions. After confirming Actinomyces-induced osteomyelitis, she was treated with 6 weeks of penicillin V combined with a course of HBOT. The infection completely resolved by the end of treatment.
What This Means for Canadian Patients
For immunocompromised Canadians, including those receiving cancer chemotherapy, unusual jaw infections can occur and may be misdiagnosed. HBOT has an established role in treating jaw bone infections (osteomyelitis), and Canadian cancer patients with non-healing dental or jaw infections should ask their care team whether a hyperbaric referral is appropriate.
Canadian Relevance
No direct Canadian connection identified. Osteoradionecrosis and osteomyelitis of the jaw are conditions where HBOT has supporting evidence; radiation-related jaw necrosis is an OHIP-covered HBOT indication in Ontario.
Study Limitations
This is a single case report, and the relative contributions of antibiotics versus HBOT to the complete recovery cannot be determined.
