What Researchers Did
This prospective, quasi-experimental study investigated the effect of hyperbaric oxygen therapy (HBOT) on bone formation markers and bone density in seven patients with cleft lip and palate (CLP) after alveolar bone grafts.
What They Found
Researchers observed a significant increase in bone morphogenetic protein 2 (BMP-2) and osteocalcin levels, and 3D CT Hounsfield units over time (ANOVA p < 0.001 for BMP-2 and osteocalcin, p = 0.01 for Hounsfield units). Specifically, serum osteocalcin showed an effect after the 1st HBOT session (adjusted b = 1.32), and serum BMP-2 after the third session (adjusted b = 6.61). After five sessions, BMP-2 increased by 28.06 ng/mL and osteocalcin by 6.27 ng/mL compared to baseline.
What This Means for Canadian Patients
For Canadian patients undergoing alveolar bone grafts for cleft lip and palate, hyperbaric oxygen therapy might offer a way to enhance bone healing and regeneration. This could potentially lead to improved outcomes and faster recovery following such reconstructive surgeries.
Canadian Relevance
This study was not conducted in Canada and does not have a direct Canadian connection.
Study Limitations
A significant limitation of this study is its very small sample size of only seven patients, limiting the generalizability of the findings.
