摘要： 目的 评价高能量CO2点阵激光和点阵射频治疗萎缩性痤疮瘢痕的疗效及安全性。方法 随机分配半脸进行治疗,一侧使用DeepFx CO2点阵激光,另一侧使用点阵射频。第一遍单点治疗凹陷痤疮瘢痕,第二遍全部痤疮瘢痕区域扫描。每次治疗间隔2个月,5次治疗结束后随访3个月,采用4分位数评分量表评价痤疮瘢痕改善情况,并观察并发症情况。结果本组共28例患者,治疗后两侧痤疮瘢痕改善无显著差异,CO2点阵激光治疗侧色素沉着显著高于点阵射频治疗侧,CO2点阵激光治疗时疼痛明显低于点阵射频治疗。两侧均未出现永久性色素改变和瘢痕。结论 高能量CO2点阵激光和点阵射频均能有效改善萎缩性痤疮瘢痕,无永久性不良反应,均可作为痤疮瘢痕的治疗选择。

Abstract: Objective To evaluate the safety and effectiveness of CO2 fractional laser and fractional radio frequency for the treatment of atrophic acne scars. Methods Half face was randomly assigned to CO2 fractional laser with DeepFx mode or fractional radio frequency. The atrophic acne scars were firstly treated by pinpoint irradiations with one pass, the second scanning was performed for whole area. Three months after five treatment sessions with interval of 2 months, improvements of acne scars were scored using a quartile grading scale, and side effects were monitored at each follow-up visit. Results Twenty-eight patients completed the study. There was no significant difference of improvements on both sides of the acne scar. Hyperpigmentation was significantly higher in CO： fractional laser treatment side than fractional radiofrequency treatment side, the pain scores of CO2 fractional laser treatment side was less than the fractional radio frequency treatment side. No permanent hypopigmentation and scarring formation were observed. Conclusion Both CO2 fractional laser and fractional radio frequency can safely and effectively improve atrophic aene scars.
