双波长非剥脱点阵激光“水增强法”治疗面部凹陷性瘢痕疗效观察

目的:探讨双波长(1320nm+1440nm)非剥脱性点阵激光"水增强法"治疗面部凹陷性痤疮瘢痕的临床疗效和安全性。方法:35例患者随机分成两组,治疗组(A组):先在凹陷性瘢痕处注射利多卡因注射液,然后再使用双波长非剥脱性点阵激光治疗;对照组(B组):仅使用双波长非剥脱性点阵激光治疗。每组间隔6周治疗1次,共5次。治疗前后均以ECCA权重评分表对瘢痕部位进行评分统计。结果:35例患者均完成治疗观察,经过整个疗程治疗后,所有凹陷性瘢痕均有不同程度的改善,A、B组治疗前后ECCA权重评分明显下降,经方差分析检验(P<0.05)差异有统计学意义。A、B组治愈率分别达55.4%和25.0%,无1例出现严重副反应,超过80%的患者表示满意和非常满意。结论:双波长非剥脱性点阵激光"水增强法"治疗面部凹陷性痤疮瘢痕疗效确切,安全性高,无明显副作用,为治疗面部凹陷性痤疮瘢痕开辟了一条新的思路。

Observation of the therapeutic effect for facial atrophic scars of acne by water augmentation Affirm double wave fractional photothermolysis laser

Objective To evaluate the efficacy and safety in the treatment for facial atrophic scars of acne by water augmentation Affirm double wave fractional photothermolysis(FP)laser.Methods 35 patients with facial atrophic acne scars were enrolled in the study.All patients were randomly divided into two groups,Group A were treated with Affirm double wave FP laser after the scars were filled with injection of Lidocaine Hydrochloride.Group B treated with Affirm double wave FP laser alone.All cases received a total of five sessions FP laser treatments at 6-week intervals.Comparative photographs were taken using B.Dreno’s ECCA grading scale to identify and quantify facial atrophic scars.Results All of the cases obtained different degree of improvement were treated by 5 times.A group and B group cure rate achieved 55.4%,25%.Over 80% patients considered their results satisfactory or very satisfactory.No severe side effect was observed.Conclusions Application of the water augmentation Affirm double wave FP laser is effective and safe in the treatment of facial atrophic acne scars,the side effects was rare,It providing a new therapeutic option for atrophic acne scars.
