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800～1200mJ、定点连续发射4～8个脉冲。毛孔粗大23例，予中脉宽、能量800～1000mJ、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，南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。
Objective To investigate the efficacy of ablative fraetionated erbium： yttrium aluminum garnet （Er： YAG） laser in facial aene seam and enlarged pores. Methods Forty-one patients with mild to moderate pitted aene sears 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 usecl to evaluate the improvement in surface roughness. Results The efficacy reached 82.93% and 86.96% for aene sears and enlarged pores, respectively. The satisfaction rate was 88.80% and 91.30% in patients with aene 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 ache sears and 5 with enlarged pores. Conclusion Ablative fractionated Er：YAG laser can efficiently resurface pitted ache scars and shrink enlarged pores.
