Effect of PRF & Fractional CO2 Laser in Postburn Hypertrophic Scars

Recent advancements in scar management include the use of Plasma Rich Fibrin (PRF) injections and fractional CO2 laser treatments. Both modalities are considered innovative approaches that offer promising outcomes in scar revision .

Plasma Rich Fibrin (PRF) is a newer modality in regenerative medicine derived from the patient's own blood. Unlike platelet-rich plasma (PRP), PRF does not use anticoagulants during processing, leading to a natural fibrin matrix that supports prolonged release of growth factors and cytokines . This matrix has been shown to enhance wound healing and improve scar texture and appearance. Studies have demonstrated PRF's efficacy in treating various skin conditions, including acne scars and general skin rejuvenation, suggesting potential benefits for postburn scar management .

Fractional CO2 laser therapy is a well-established technique for scar treatment, including postburn scars. This technology utilizes laser energy to create microthermal zones in the skin, which stimulates collagen production and skin remodeling while minimizing damage to surrounding tissues . Clinical trials have validated the effectiveness of fractional CO2 lasers in reducing scar thickness and improving skin texture, making it a popular choice for scar revision .

Postburn scars often result in significant functional and aesthetic challenges for plastic surgeons. These scars can cause physical limitations, psychological distress, and a decrease in quality of life. Traditional treatments, including topical therapies, silicone gel sheets, and surgical interventions, frequently fall short in providing optimal results, particularly for extensive or complex scars .

Despite the individual benefits of PRF and fractional CO2 laser treatments, there is a lack of direct comparative studies assessing their relative efficacy in postburn scar management. Comparative research is essential to determine which treatment provides superior outcomes and to guide clinical decision-making .
