超脉冲CO2点阵激光多模式联合治疗面部痤疮凹陷性瘢痕的疗效观察

［摘要］目的　观察国产超脉冲CO2点阵激光多模式联合治疗面部痤疮凹陷性瘢痕的效果和安全性．方法　选80例面部凹陷性痤疮瘢痕患者，随机分为2组，对照组40例单纯点阵模式治疗，观察组40例采用超脉冲CO2点阵激光多模式联合治疗，观察并比较2组患者的治疗效果及并发症．结果　观察组中患者治疗总有效率95%，对照组患者总有效率70%，2组患者比较差异有统计学意义（P＜0.05）；2组均无永久色素沉着、色素脱失及明显疤痕．结论　国产超脉冲CO2点阵激光治疗面部凹陷性痤疮瘢痕有效安全，且多模式联合治疗效果优于单纯点阵模式.

Curative Effect of Multimode Combined Treatment of Ultrapulsed CO2 Laser on Facial Atrophic Acne Scars

［Abstract］Objective　To observe the safety and effectivity of the multimode combined treatment of domestic ultrapulsed CO2 laser on infacial atrophic acne scars. Methods　Eighty patients with facial atrophic acne scars were randomly divided into Simple lattice model therapy group and multimode combinedultrapulsed CO2 laser group.The therapeutic effects and complication were observed and compared between two groups．Results　The total effective rate in multimode combinedultrapulsed CO2 lasertherapy group was 95%， the total effective rate in Simple lattice model therapy group was 70%. There was a significant difference between two groups（ P＜0.05）. No permanent hyperpigmentation，depigmentation and obvious scar were observed. Conclusions　Multimode combined treatment of domestic ultrapulsed CO2 laser is effective and safe in the treatment of facial atrophic acne scars. It is better than Simple lattice model therapy.
