Gedetailleerde beschrijving
Post-traumatic atrophic scars are characterized by dermal collagen loss, epidermal thinning, and alterations in skin texture and pigmentation. These scars may result in significant cosmetic disfigurement and negatively affect patients' quality of life. Despite the availability of multiple treatment modalities, no single intervention has consistently demonstrated optimal efficacy.
Fractional carbon dioxide (CO2) laser induces controlled microthermal injury that stimulates collagen remodeling and skin regeneration. Autologous nanofat grafting, which is rich in adipose-derived regenerative cells and growth factors, has emerged as a promising regenerative treatment for improving skin quality and scar remodeling. Combining these two modalities may provide synergistic effects by enhancing tissue regeneration and improving both structural and aesthetic outcomes.
This prospective comparative study was conducted to evaluate and compare the safety and efficacy of fractional CO2 laser monotherapy, autologous nanofat injection monotherapy, and combination therapy in the treatment of post-traumatic atrophic scars. Clinical efficacy was assessed using physician evaluation, Vancouver Scar Scale scores, and patient satisfaction, while dermoscopic and histopathological examinations were performed to investigate treatment-induced structural changes and the mechanisms underlying scar improvement.
The study aimed to determine whether combined therapy offers superior clinical and regenerative outcomes compared with either treatment alone while maintaining an acceptable safety profile.
