Evaluating the Role of Hyperbaric Oxygen Therapy in Enhancing Skin Graft Outcomes: Mechanisms, Clinical Evidence, and Comparative Efficacy

Skin grafting is a critical procedure for treating skin defects from burns, trauma, and surgical interventions, yet complications such as ischemia, necrosis, and infection can limit graft success. Hyperbaric Oxygen Therapy (HBOT) has emerged as a promising adjunctive treatment that enhances skin graft viability through mechanisms including enhanced oxygenation, angiogenesis, reduced inflammation, and anti-infective effects. This review synthesizes findings from clinical studies, comparative analyses, and case reports to clarify HBOT’s efficacy in improving skin graft outcomes. Methods include a comprehensive analysis of HBOT’s impact on graft take rates, healing times, and complication rates. Results indicate that HBOT significantly improves graft survival by mitigating ischemia and infection, while comparative studies show a reduction in major amputations and improved healing in complex cases, such as diabetic foot ulcers and traumatic injuries. These findings suggest that HBOT can serve as a valuable adjunct to standard grafting procedures, offering a multifaceted approach to improve graft viability, especially in high-risk cases. This review highlights HBOT’s potential for integration into wound management protocols, providing a foundation for further exploration into its efficacy and applications in reconstructive surgery.
