超脉冲点阵CO2激光治疗面部外伤后瘢痕疙瘩疗效观察OA

Objective To explore the aesthetic effect of ultra-pulse fractional CO2 laser on facial trauma scar.Methods Ninety-six patients with facial trauma keloid admitted to the hospital from January 2022 to February 2024 were randomly divided into control group and observation group,48 cases in each group.The control group was given triamcinolone acetonide injection,and the observation group was given ultra-pulse fractional CO2 laser combined with triamcinolone acetonide injection.The clinical efficacy,scar repair,aesthetic effect and adverse reactions were compared between the two groups.Results The clinical curative rate of the observation group was significantly higher than that of the control group[95.83%(46/48)vs.81.25%(39/48),P＜0.05].After 3 and 6 months of treatment,the scores of Vancouver Scar Scale(VSS)and scar tissue thickness in both groups decreased,and the VSS scores and scar tissue thickness in the observation group were significantly lower than those in the control group(P＜0.05).After treatment,the scores of comfort,acceptability,social influence,self-perception,pigmentation,skin texture,softness and smoothness in the observation group were significantly higher than those in the control group(P＜0.05).There was no significant difference in the total incidence of adverse reactions between the control group and the observation group[12.50%(6/48)vs.16.67%(8/48)](P＞0.05).Conclusion Ultra-pulse fractional CO2 laser combined with triamcinolone acetonide is effective in the treatment of facial trauma keloid,which can promote scar tissue repair and enhance aesthetic effect,and has certain safety.
