中文摘要：

将108例面部脂溢性角化病患者随机分为3组，分别用Q开关Nd：YAG532nm激光、铒激光和强脉冲光（IPL）治疗，根据患者每次治疗前的照片评估治疗效果及不良反应。结果显示3种治疗方法停工期比较差异有统计学意义（P〈0．05），IPL组优于Q开关532nm激光组及铒激光组；患者疼痛度的比较差异无统计学意义；3种治疗方法均安全有效，有效率和术后局部色素改变比较差异均无统计学意义。

英文摘要：

Abstract 108 patients with facial seborrheic keratosis were randomly divided into three groups,which were treated with Q-switched Nd：YAG 532 nm laser, erbium laser and intense pulsed light respectively. The assessment of effect and adverse reactions were based on the photos before each treatment. Three methods of treatment of downtime comparative difference was statistically significant. Intense pulsed light group was better than that of Q-switched 532 nm and erbium laser group. There was no statistically significant difference compared with the patients pain degrees. Three methods were safe and effective treatment. Efficient and postoperative local pigment change comparative differences had no statistical significance.
