铒激光联合E光治疗痤疮凹陷性瘢痕的临床效果评价

目的：评价铒激光联合E光治疗痤疮凹陷性瘢痕的临床疗效和安全性。方法：将大连市皮肤病医院美容皮肤科2013年1月至2016年6月就诊患者采用双色球方法随机分成治疗组和对照组，治疗组为铒激光联合E光治疗组；对照组为铒激光治疗组,每个月治疗一次，共3次。对照组与治疗组均于疗程结束1个月后比较两组患者治疗前后皮肤红斑、色沉，瘢痕，皱纹，粗糙度，光滑度的变化。结果：共就诊62例痤疮凹陷性瘢痕患者，治疗组31例，对照组31例，治疗组与对照组患者皮损治疗前光滑度、瘢痕、皱纹、粗糙度、色沉、红斑比较，差异无统计学意义(P＞0.05)。治疗后，治疗组，患者皮肤的光滑度,瘢痕,皱纹,粗糙度,红斑,色沉评分分别为73.32±0.236、2.21±0.152、168.6±0.177、63±0.128、8.63±0.122、5.20±0.232，对照组分别为70.45±0.354、3.28±0.138、180.6±0.412、66±0.422、13.62±0.121、11.22±0.121，两组比较差异有统计学意义(均P<0.05)。所有患者未见严重不良反应。结论：铒激光联合E光治疗痤疮凹陷性瘢痕较单独应用铒激光治疗组疗效明显提升。

Clinical effect of ELectiric Light Synergy and erbium fractional laser for treating atrophic acne scar

Objective: To assess the efficacy of electiric light synergy and erbium fractional laser in the treatment of atrophic acne scars. Methods: The patients with atrophic acne scars in the department of aesthetic dermatology, Dalian dermatology hospital from January 2013 to June 2016 were collected and randomly divided into two groups. The patients with in the treatment group were treated with erbium fractional laser and electiric light synergy and those in the control group were treated with erbium fractional laser only, once a month for three times. The efficacies of both therapies were assessed by hyperpigmentation, erythem, scar, wrinkle, roughness. Results: Sixty-two patients were collected, 31 patients in each group. There was no significant difference of hyperpigmentation, erythem, scar, wrinkle, roughness between the two groups (P＞0.05). After treatment, the score of skin smoothness, scar, wrinkles, roughness, erythema, hyperpigmentation were 73.32±0.236、2.21±0.152、168.6±0.177、63±0.128、8.63±0.122、5.20±0.232 respectively and those in the control group were 70.45±0.354、3.28±0.138、180.6±0.412、66±0.422、13.62±0.121、11.22±0.121，with significant differences (P<0.05). Conclusion: Erbium fractional laser combined with electiric light synergy is more effective in the treatment of acne sag scar than Focal erbium fractional laser alone.
