目的:探讨超脉冲二氧化碳点阵激光治疗皮肤痤疮瘢痕的疗效和安全性。方法:本试验对26名痤疮瘢痕患者进行点阵激光治疗,并分别于术前、术后7天、术后1个月、术后3个月分别进行数码照相、无创皮肤检测、记录恢复过程和副作用。通过前后对比,观察临床效果和副作用。医生对治疗效果进行4级评分,患者对疗效的满意率也进行4级评分。结果:超脉冲二氧化碳点阵激光是痤疮瘢痕的有效治疗手段。术后3个月,80.8%的患者改善率超过50%;92.3%的患者达到满意或非常满意的效果。
Objective To investigate the efficacy and safety of fractionated ultrapulse CO2 laser in treating acne scar.Methods Twenty-six patients with acne scar were treated with fractionated CO2 laser.Digital photos and non-invasive skin measurements were taken before the treatment,1 to 7days,1 month and 3 months after the treatment to evaluate the efficacy.The recovery process and side effects were also recorded to assess the safety.Dermatologists rate the efficacy in a 4-points scales.The patients of overall satisfaction in a 4-point scales.Result Fractionated ultrapulse CO2laser is an effective way to treat acne scar with minimized side effects.Three months post treatment 80.8% of the patients have improvement of over 50% and 92.3% of the patients are satisfied or very satisfied with the overall efficacy.
