摘要目的 分析皮秒翠绿宝石激光治疗太田痣的疗效、安全性和影响因素.方法 2015年10月至2017年10月,中国医学科学院皮肤病医院激光科对49例太田痣患者进行皮秒翠绿宝石激光治疗,并根据患者性别、发病年龄、治疗1次年龄、皮损Tanino分型和颜色分级进行分组,对临床特征、治疗效果、不良反应、疗效影响因素等进行分析.结果 49例太田痣患者接受1～4次治疗,痊愈9例,其中治疗1次痊愈3例.治疗1次显效率达28.6％,有效率达53.1％,8例治疗3次全部有效,5例治疗4次全部显效.不同性别、发病年龄、Tanino分型、颜色分级各组之间的治疗1次疗效比较,差异无统计学意义(P＞0.05).治疗1次年龄与疗效差异有统计学意义(P＜0.05),年龄与疗效呈反比关系,年龄越小,效果越好.2例患者治疗后出现色素沉着,6个月后消退,无明显瘢痕、色素减退等不良反应出现.结论 皮秒翠绿宝石激光治疗太田痣疗效好,安全性高.
