Methods Nineteen patients with large superficial facial scars were treated by the same surgeon with dermabrasion combined with ReCell？. According to the etiology, patients were classified into post-burning group （n=5）, post-traumatic group （n=7） and post-acne group （n=7）. Fifteen patients completed the follow-ups, 5 patients in each group. Healing time, complication rate, the preoperative and 18-month-post-operative assessments using Patient Satisfaction Score （PSS）, Vancouver Scar Scale （VSS）, and Patient and Observer Scar Assessment Scale （POSAS） of each group were analyzed to compare the effect of the combined therapy on outcomes.Results The healing time of post-burning group （19.6±4.0 days）, post-traumatic group （15.8±2.6 days）, and post-acne group （11.4±3.1 days） varied remarkably （F=7.701, P=0.007）. The complication rates were 60%, 20%, and 0 respectively. The post-operative POSAS improved significantly in all groups （P〈0.05）, where the most significant improvement was shown in the post-acne group （P〈0.05）. The post-operative PSS and VSS improved only in the post-traumatic group and post-acne group （all P〈0.05）, where the more significant improvement was also shown in the post-acne group （P〈0.05）. Conclusions The combined treatment of dermabrasion and ReCell has remarkable effect on acne scars, moderate effect on traumatic scars and is not suggested for burn scars. POSAS should be applied to assess the therapeutic effects of treatments for large irregular scars.展开更多
目的:采用Meta分析比较A型肉毒毒素联合类固醇激素与单独类固醇激素治疗病理性瘢痕的疗效及安全性。方法:计算机检索截止2021年3月的Pubmed、EMbase、Cochrane Central Register of controlled Trail、中国知网、万方、维普以及中国生...目的:采用Meta分析比较A型肉毒毒素联合类固醇激素与单独类固醇激素治疗病理性瘢痕的疗效及安全性。方法:计算机检索截止2021年3月的Pubmed、EMbase、Cochrane Central Register of controlled Trail、中国知网、万方、维普以及中国生物医学文献数据库中公开发表的关于A型肉毒毒素联合类固醇激素与单独类固醇激素治疗病理性瘢痕的临床对照实验。由2名研究员根据纳入及排除标准独立筛选文献、提取资料及质量评价。使用RevMan 5.3和Stata 14.0统计软件,对结局指标进行Meta分析。结果:共纳入11项研究,包括8项随机对照试验,3项病例-队列研究,试验组采用A型肉毒毒素联合类固醇激素局灶内注射,对照组采用类固醇激素局灶内注射,纳入文献总体质量较高。Meta分析结果表明,试验组在目测类比评分[WMD=-2.26,95%CI(-3.07,-1.46),P<0.00001]、瘢痕厚度[WMD=-0.94,95%CI(-1.82,-0.06),P=0.04]、满意度评分[WMD=1.51,95%CI(1.21,1.81),P<0.00001]、有效率[RR=1.30,95%CI(1.17,1.43),P<0.00001]、复发率[RR=0.23,95%CI(0.11,0.49),P=0.0002]、不良反应发生率[RR=0.65,95%CI(0.42,0.99),P=0.04]等指标均优于对照组,而治疗后两组间瘢痕长度无显著性差异[SMD=-4.30,95%CI(-11.56,2.96),P=0.25]。结论:A型肉毒毒素联合类固醇激素治疗病理性瘢痕的疗效及安全性均优于单独使用类固醇激素。展开更多
