摘要目的:Meta分析评估黄金微针射频与其他光电类治疗面部痤疮凹陷性瘢痕的有效性及安全性。方法:检索2015年1月至2022年8月在中国知网、万方数据库、维普、中国生物医学文献服务系统、PubMed、The Cochrane Library、Embase数据库已发表黄金微针射频治疗面部痤疮凹陷性瘢痕的随机对照试验，最终纳入12篇文献；中文文献6篇，英文文献6篇，样本量612例。结果:黄金微针射频治疗面部痤疮凹陷性瘢痕的效果更优( P<0.05)，进行亚组分析后，治疗4次后观察组有效率高于对照组，差异有统计学意义( P<0.05)。临床痤疮瘢痕评估量表、疼痛评分、休工期有统计学意义( P<0.05)。 结论:黄金微针射频单独或协同其他光电类治疗面部痤疮凹陷性瘢痕休工期短，疼痛感轻微，改善瘢痕效果明显；但对冰锥型凹陷性瘢痕改善效果有限。

abstractsObjective:To evaluate the efficacy and safety of gold micrhenedle radiofrequency and other photoelectric methods in the treatment of facial acne depression scar by using a meta-analysis.Methods:From January 2015 to August 2022, gold microneedles and radio frequence for treatment of facial acne depression scar of randomized controlled trial were retrieved from CNKI, Wanfang Database, VIP, China Biomedical Literature Service System, PubMed database, Cochrane Library and Embase database, including 12 papers. There were 6 Chinese and 6 English literatures, with a sample size of 612 cases.Results:Gold microneedling radio-frequency showed better efficacy in the treatment of facial acne depression scar ( P<0.05). After subgroup analysis, the effective rate in the observation group was higher than that in the control group after 4 treatments, and the difference was statistically significant ( P<0.05). Clinical acne scarring assessment scale, pain score and recovery time had statistically significant difference ( P<0.05). Conclusions:Gold microneedling radiofrequency alone or in collaboration with other photoelectricity in the treatment of acne depression scar has short rest period, slight pain, and obvious improvement of scar effect. However, the improvement effect on icicle depression scar is limited.
