像素铒激光配合果酸治疗黄褐斑的疗效观察

Pixel Erbium laser treatment of melasma with the efficacy of acid

目的:观察像素铒激光(2940nm)联合羟基乙酸(果酸)治疗黄褐斑的临床疗效和安全性,掌握像素铒激光和果酸换肤的治疗方法。方法:应用质量浓度20%、35%的果酸对30例黄褐斑患者进行治疗,2～3周1次,5次为1个疗程;应用短脉宽像素铒激光对30例黄褐斑患者进行治疗,每2～3周1次,4次为1个疗程。两种方法交替使用,15天治疗1次。结果:随着治疗次数的增加,褐色斑逐渐变淡,MASI评分逐渐下降,有效率为60%。30例患者完成一个疗程的治疗,有效率表皮型黄褐斑83.33%,混合型44.44%,表皮型比混合型患者MASI下降更显著(P<0.05)。结论:像素铒激光联合果酸治疗黄褐斑是一种安全性好,修复快,不良反应少的方法,对于表皮型黄褐斑比混合型效果更明显。

Objective Observed pixel erbium laser （2940） joint-hydroxy acid （AHA） in the treatment of melasma clinical efficacy and safety,master pixel erbium laser and chemical peel treatments. Methods The concentration of 20%, 35% of the acid were 30 cases of chloasma treated 2-3 weeks time, 5 times for a course of treatment. Application of short- pulse erbium laser pixels were 30 cases of melasma treatment, once every 2-3 weeks, four times for one course, two methods are used interchangeably, 15 days of treatment time.There are two doctors on fixed lesions in patients with melasma area and severity index （MASI） score, for the use of self-efficacy before and after treatment were observed and recorded the response of patients after treatment. Results The number of treatments increases, the brown spots gradually fades, MASI score decreased, the effective rate of 60%. 30 patients completed a course of treatment, efficiency： epidermal melasma was 83.33%, 44.44% mixed type, skin type than the mixed type decreased more significantly in patients with MASI （P〈0.05）. Conclusion Pixel Erbium laser and acid treatment of melasma, is a safe and good, quick repair, adverse reaction method; for epidermal melasma is more effective than the mixed type.
