The repair effect of autologous fat transplantation combined with carbon dioxide lattice laser on hypertrophic scars in burn patients
Objective To evaluate the repair effect of autologous fat transplantation combined with carbon dioxide lattice laser on hypertrophic scars in burn patients.Method:A retrospective analysis was conducted on the clinical data of 54 patients with post burn hypertrophic scars admitted to the Plastic Surgery Department of Renji Hospital in Zhengzhou from October 2020 to February 2023.They were grouped according to the time of admission for treatment.27 patients with post burn hypertrophic scars treated from October 2020 to January 2022 were used as the control group,and 27 patients with post burn hypertrophic scars treated from February 2022 to February 2023 were used as the observation group.The control group patients were all treated with carbon dioxide lattice laser,while the observation group patients were treated with autologous fat transplantation combined with carbon dioxide lattice laser.Compare the treatment efficacy,scar recovery,scar blood flow perfusion,and incidence of adverse reactions between two groups of patients.After treatment,the effective rate of treatment in the observation group was higher than that in the control group(P<0.05);The Vancouver Scar Scale(VSS)score of the observation group was lower than that of the control group(P<0.05);The scar blood flow perfusion in the observation group was lower than that in the control group(P<0.05);During the treatment period,8 patients in the observation group experienced adverse reactions,while 6 patients in the control group.There was no significant difference in the total incidence of adverse reactions between the two groups(P>0.05).Conclusion:The application of autologous fat transplantation combined with carbon dioxide dot matrix laser in the treatment of hypertrophic scars after burns can improve the treatment effect,help improve the scar color,scar thickness,vascular distribution,softness,and scar congestion in patients,make the scar disappear,and have safety.
