目的：：评价射频点阵技术治疗面部凹陷性痤疮瘢痕的疗效和安全性。方法：43例患者,采用MatrixTM RF射频点阵技术每4~6周治疗1次,共治疗3次。治疗结束后1个月,采用Dreno推荐的 ECCA权重评分表法评价疗效。结果：治疗前后ECCA权重评分值分别为47.50±24.35和85.60±42.74,差异有统计学意义( P＝0.000)。3例患者治疗后出现轻微色素沉着,避强光后3个月内自行消退。结论：射频点阵技术治疗面部凹陷性痤疮瘢痕安全、有效。

Objective:To evaluate the efficacy and safety of the fractional radiofrequency in the treatment of facial atrophic acne scars. Methods:Forty-three patients were treated with MatrixTM RF fractional radiofre￣quency, once every 4 to 6 weeks, for 3 times. The efficacy were assessed by Dreno’ s ECCA grading scale af￣ter the trearment for one month. Results: ECCA weight grade scale after the treatment was 47. 50 ± 24. 35, which was lower than that before the treatment (85.60±42.74), with a significant difference (P=0.000). Three patients presented slight pigmentation after treatment and resolved spontaneously after 3 months. Conclusion:Fractional radiofrequency was effective and safe in the treatment of facial atrophic acne scars.
