摘　　要：目的:比较CO_2点阵激光和2 940nm点阵铒激光治疗凹陷性痤疮瘢痕的疗效及安全性。方法:凹陷性痤疮瘢痕患者55例,采用CO_2点阵激光治疗29例,2 940nm点阵铒激光治疗26例。治疗前后使用ECCA权重评分表对治疗部位进行评分并记录不良反应的发生率,比较两种治疗方法的疗效差异和安全性。结果:CO_2点阵激光治疗组治疗前ECCA评分平均为(259.12±213.51)分,治疗后为(152.63±168.32)分,治疗前后比较差异有统计学意义(t=2.526,P=0.014),有效率为93.1%,治愈率为58.6%;2 940nm铒激光点阵治疗组治疗前ECCA评分平均为(223.54±235.08)分,治疗后为(139.62±130.35)分,治疗前后比较差异有统计学意义(t=3.853,P=0.026),有效率为84.6%,治愈率为30.8%。两组治疗有效率比较,差异无统计学意义(P>0.05)。CO_2点阵激光治疗组色素沉着等并发症发生率均大于2 940nm点阵铒激光治疗组。结论:两种点阵激光治疗痤疮凹陷性瘢痕均安全、有效,CO_2点阵激光更适合较粗大瘢痕的磨削,而2 940nm点阵铒激光更适合精细的瘢痕磨削且热损伤更小。Objective To compare the clinical effects and safety of acne scars treated by the CO2 fractional laser and Fractional Erbium Laser（2 940 nm）, for exploring a safety, efficacy physical method. Methods Give different treatments in 5 months to two groups of acne scars patients, respectively with the CO2 fractional laser and Fractional Erbium Laser（2 940 nm）.ECCA grading scale, pain level and complications were assessed and compared. Results In the group of 29 patients with the CO2 fractional laser, total effective rate was 93.1%; in the group of 26 patients with the Fractional Erbium Laser（2 940 nm）,total effective rate was 84.6%.There was not statistics difference between two groups in clinical effective rates（P〉 0.05）. However,the later had less complications. Conclusion Two kinds of laser therapeutic methods are safety and efficacy.
