Background: Scar management remains a significant challenge in plastic and reconstructive surgery, particularly when addressing atrophic, retractile, or fibrotic scars. Autologous fat grafting and hybrid fractional laser therapy have independently shown efficacy in improving scar quality. This study aims to evaluate the synergistic effect of their combination on clinical and functional scar outcomes. Methods: A prospective, comparative study was conducted on patients with cutaneous scars of various etiologies. Participants were treated with either hybrid fractional laser therapy alone (CO2 and 1570 nm Erbium-glass wavelengths) or a combined protocol of laser plus autologous lipofilling. Clinical outcomes were assessed at baseline and at 30, 60, and 90 days post-treatment using the Vancouver Scar Scale (VSS), patient satisfaction scores, and Visual Analog Scale (VAS) for pain and discomfort. Results: Patients receiving the combined treatment demonstrated significantly greater improvement in scar pigmentation, elasticity, pliability, and thickness compared to those treated with laser alone. Subjective symptoms, including pain and itching, were also more effectively alleviated. The volumetric and regenerative properties of adipose tissue, particularly its content of adipose-derived stem cells (ADSCs) and stromal vascular fraction (SVF), likely contributed to the enhanced outcomes observed. Conclusions: The combination of hybrid fractional laser therapy and autologous lipofilling offers a superior therapeutic strategy for scar remodeling compared to laser monotherapy. This integrated regenerative approach addresses both structural and biological aspects of scar tissue, making it a valuable protocol for personalized and effective scar management. Further randomized trials with larger sample sizes and histological validation are warranted to confirm these preliminary findings and refine therapeutic protocols.

Abstract
Background: Scar management remains a significant challenge in plastic and reconstructive surgery, particularly when addressing atrophic, retractile, or fibrotic scars. Autologous fat grafting and hybrid fractional laser therapy have independently shown efficacy in improving scar quality. This study aims to evaluate the synergistic effect of their combination on clinical and functional scar outcomes. Methods: A prospective, comparative study was conducted on patients with cutaneous scars of various etiologies. Participants were treated with either hybrid fractional laser therapy alone (CO2 and 1570 nm Erbium-glass wavelengths) or a combined protocol of laser plus autologous lipofilling. Clinical outcomes were assessed at baseline and at 30, 60, and 90 days post-treatment using the Vancouver Scar Scale (VSS), patient satisfaction scores, and Visual Analog Scale (VAS) for pain and discomfort. Results: Patients receiving the combined treatment demonstrated significantly greater improvement in scar pigmentation, elasticity, pliability, and thickness compared to those treated with laser alone. Subjective symptoms, including pain and itching, were also more effectively alleviated. The volumetric and regenerative properties of adipose tissue, particularly its content of adipose-derived stem cells (ADSCs) and stromal vascular fraction (SVF), likely contributed to the enhanced outcomes observed. Conclusions: The combination of hybrid fractional laser therapy and autologous lipofilling offers a superior therapeutic strategy for scar remodeling compared to laser monotherapy. This integrated regenerative approach addresses both structural and biological aspects of scar tissue, making it a valuable protocol for personalized and effective scar management. Further randomized trials with larger sample sizes and histological validation are warranted to confirm these preliminary findings and refine therapeutic protocols.Pubblicazioni consigliate
