【摘要】 目的对超脉冲CO2激光和连续CO2激光治疗睑缘色素痣临床效果和安全性进行比较.方法采用队列研究,病例共205例,其中超脉冲CO2激光治疗组100例,连续CO2激光治疗组105例,观察各自的疗效、色素沉着、疤痕、结痂时问、脱痂时间情况.结果两组病例有效率差异无统计学意义(P>0.05),超脉冲CO2激光治疗组皮损处色素沉着及疤痕率明显较连续CO2激光治疗组低(P<0.05);结痂时间、脱痂时间也均较短(P<0.05).结论超脉冲CO2激光治疗睑缘色素痣的效果优于较连续CO2激光.更多还原

【Abstract】 Objective To compare the therapeutic effect and safety of ultrapulse CO2 laser and continuous CO2 laser on palpebral margin pigmented nevus.Methods We used cohort study to research 205 patients with palpebral margin pigmented nevus,including 100 patients received ultrapulse CO2 laser treatment(ultrapulse CO2 laser group)and 105 patients received continuous CO2 laser treatment(continuous CO2 laser group).And then we observed the effect,pigmentation,scar,time of incrustation and the decrustation.Results There was no significant difference in the therapeutic effect between the two groups(P>0.05).The pigmentation and scar rates of ultrapulse CO2 laser group were significantly lower than continuous CO2 laser group(P<0.05).And the time of incrustation and decrustation in ultrapulse CO2 laser group were shorter than continuous CO2 laser group(P<0.05).Conclusion The therapeuticeffect of ultrapulse CO2 laser was better than continuous CO2 laser in treatment of palpebral margin pigmented nevus.更多还原
