Nanofat Injection and Fractional CO2 Laser for Post-Traumatic Atrophic Scars

Brief Summary

Post-traumatic atrophic scars are characterized by skin depressions caused by loss of collagen and can lead to cosmetic and psychological concerns. Several treatment options have been proposed, including fractional carbon dioxide (CO2) laser resurfacing and autologous nanofat grafting, both of which may improve scar appearance through skin remodeling and regeneration. This prospective comparative study evaluates the safety and efficacy of fractional CO2 laser alone, autologous nanofat injection alone, and combination therapy in patients with post-traumatic atrophic scars. Sixty participants were assigned to one of three treatment groups and were assessed using the Vancouver Scar Scale, physician global assessment, patient satisfaction, dermoscopic examination, and histopathological evaluation. The study aims to determine whether combining fractional CO2 laser and nanofat injection provides superior clinical and regenerative outcomes compared with either treatment alone while maintaining an acceptable safety profile.
