Abstract
Objective To explore the clinical effects of pulsed dye laser(PDL)combined with ultra-pulsed fractional CO2 laser(UFCL)in the treatment of mild hypertrophic scars.Methods From May 2019 to May 2022,99 patients with post-surgical and post-traumatic mild hypertrophic scars treated at our hospital were selected and divided into two groups.The control group was treated with UFCL(n=56),while the observation group received combined treatment with PDL on the basis of the control group(n=43).The clinical efficacy,scar recovery time,repair outcomes[assessed by the Patient and Observer Scar Assessment Scale(POSAS),University of North Carolina(UNC)Scar Scale,and Vancouver Scar Scale(VSS)],and the incidence of adverse reactions were compared between the two groups.Results Three months after treatment,the total effective rate of the observation group was significantly higher than that of the control group(χ2=4.029,P=0.045).The durations of residual erythema,inflammatory exudation,and crusting in the observation group were all lower than those in the control group(P＜0.05).At three months post-treatment,the scores of POSAS,UNC,and VSS in the observation group were lower than those in the control group(P＜0.05).No significant difference was found in the incidence of adverse reactions between the two groups during the treatment period.Conclusion PDL combined with UFCL was superior to UFCL alone in terms of clinical efficacy,scar recovery quality,and repair outcomes,and can be considered an effective and safe treatment option,which could be more widely used and promoted in the treatment of post-surgical and post-traumatic hypertrophic scars.关键词
