摘要: 目的 探讨点阵式掺铒钇铝石榴石(Er:YAG)激光对于面部凹陷性痤疮瘢痕及毛孔粗大的疗效。方法 轻至中度凹陷性痤疮瘢痕41例,予中长脉宽、能量800 ~ 1200 mJ、定点连续发射4 ~ 8个脉冲。毛孔粗大23例,予中脉宽、能量800 ~ 1000 mJ、定点连续发射2 ~ 4个脉冲。疗程为3 ~ 5次,每次间隔1个月。由医生对治疗后皮损改善程度进行评价,由患者对疗效进行满意度评价。应用三维皮肤成像仪获取皮肤立体图像,评价治疗对皮肤粗糙度的影响。结果 医生评估痤疮瘢痕患者皮损改善程度为82.93%,毛孔粗大患者皮损改善程度为86.96%;两种皮损患者满意率分别为88.80%和91.30%;与治疗前相比,治疗后表示粗糙度的Ra值及Rz值分别下降18.74%和21.01%(P < 0.001)。结论 点阵式Er:YAG激光可有效改善面部轻中度凹陷性痤疮瘢痕及毛孔粗大。

Abstract: Objective To investigate the efficacy of ablative fractionated erbium: yttrium aluminum garnet (Er: YAG) laser in facial acne scars and enlarged pores. Methods Forty-one patients with mild to moderate pitted acne scars and 23 patients with enlarged pores were treated with 81 (9 × 9) bits of facula for 3 to 5 sessions at an interval of 1 month. For acne scars, the pulse duration was medium to long, energy at 800 to 1200 mJ, and number of stacking passes 4 to 8; for enlarged pores, the pulse duration was medium, energy at 800 to 1000 mJ and number of stacking passes 2 to 4. The clinical improvement was evaluated by 2 blinded dermatologists. Meanwhile, the satisfaction rate was self-assessed by patients. Three-dimensional (3D) microtopography imaging system was used to evaluate the improvement in surface roughness. Results The efficacy reached 82.93% and 86.96% for acne scars and enlarged pores, respectively. The satisfaction rate was 88.80% and 91.30% in patients with acne scars and those with enlarged pores, respectively. After treatment, the Ra and Rz values, as the indicators of roughness, decreased by 18.74% and 21.01%, individually (P < 0.001) in 11 patients including 6 with acne scars and 5 with enlarged pores. Conclusion Ablative fractionated Er:YAG laser can efficiently resurface pitted acne scars and shrink enlarged pores.
