Photoshop评价激光治疗痤疮凹陷性瘢痕疗效的探索

1、I一论文发表专家一）中国学木期刊网wwwrqikanwang,netPhotoshop评价激光治疗座疮凹陷性瘢痕疗效的探索摘要目的：探索 photoshop 在点阵 er: yag 激光治疗座疮凹 陷性瘢痕疗效分析中应用的可行性。方法：将点阵 er: yag 激光治 疗座疮凹陷性瘢痕患者的术前、术后照片输入计算机，并用 photoshop cs5 对每例患者正常部位及凹陷性瘢痕部位进行灰度值 计算，然后计算激光术前灰度值差异率、激光术后灰度值差异率及 凹陷性瘢痕改善率。结果：激光术后灰度值差异率小于激光术前 灰度值差异率，两组之间差异有显著性（pv0.05 ）;随着视觉评 分的增高，凹陷性瘢痕

2、灰度值改善率增加，评分为 1 分、2 分组与 评分为 3 分、4 分组之间差异有显著性（pv0.05 ）;激光治疗次 数为 3 次及 3 次以上组与治疗次数为 2 次及 2 次以下组凹陷性瘢痕 灰度值改善率分别为 3.3%及 1.6%,但两组之间无显著性差异（p 0.05 ）。结论：photoshop 可以作为座疮凹陷性瘢痕疗效性评价的 客观评价方法；点阵 er : yag 激光治疗座疮凹陷性瘢痕有效。关键词座疮；凹陷性瘢痕；photoshop ;点阵 er: yag中图分类号r758.73+3 文献标识码a 文章编号1008-6455 （2012） 05-0806-03explore of
