二氧化碳激光联合皮下分离技术在痤疮凹陷性瘢痕中的运用

Application of CO2 laser combined with Subcision on Facial Acne Atrophic Scar

目的观察二氧化碳激光联合皮下分离技术治疗痤疮凹陷性瘢痕中的临床疗效。方法收集2018年3月~2019收集2019年12月至我院皮肤科门诊就诊的痤疮凹陷性瘢痕患者共58例,利用随机对照表法按1:1比例分为联合组和对照组。联合组29例,采用二氧化碳激光联合皮下分离技术治疗;对照组29例,采用二氧化碳激光治疗。比较两组患者治疗前、后临床疗效、ECCA评分、脱痂时间及不良反应发生率等情况。结果治疗前、后临床疗效、ECCA评分比较,差异均具有统计学意义(治疗前、后临床疗效、ECCA评分比较,差异均具有统计学意义(P<0.05);两组患者术后色素沉着率、面部持续性红斑发生率比较,差异均无统计学意义(P>0.05);联合组脱痂时间稍晚于对照组,差异有统计学意义(P<0.05)。结论二氧化碳激光联合皮下分离技术治疗凹陷性瘢痕安全有效,值得在临床推广运用。

Objective To observe the clinical efficacy of CO2 laser combined with Subcision in treating acne depression scars.Methods A total of 58 patients with acne pitting scars who visited our dermatology clinic from March 2018 to December 2019 were collected.Randomized control table method was used to divide the combination treatment group and control group according to the ratio of 1:1.The combined treatment group included 29 patients and was treated with CO2 laser combined with Subcision;the control group was 29 patients;The control group contained 29 patients and was treated with CO2 laser.The clinical efficacy,ECCA score,exfoliation time,and incidence of adverse reactions were compared between the two groups of patients.Results The differences in clinical efficacy and ECCA score before and after treatment were statistically significant(P<0.05);the postoperative pigmentation rate and the incidence of persistent erythema in the two groups were not statistically significant(P>0.05));The time of exfoliation was slightly later in the combination treatment group than in the control group,and the difference was statistically significant(P<0.05).Conclusion CO2 laser combined with Subcision is safe and effective in treating depression scars,and is worthy of clinical application.
