摘要目的 探讨小光斑低能量1064 nm Q开关激光治疗黄褐斑的效果.方法 2012年1月至2015年6月,上海光博士医疗美容门诊部用1064 nm Q开关激光治疗黄褐斑患者46例,光斑直径3～4 nm,能量密度2.8～3.5 J/cm2,每个月1次,6～10次为1个疗程.结果 治疗46例,基本治愈23例,占50.0％;显效18例,占39.1％;好转3例,占6.5％;无效2例,占4.3％,有效率为89.1％.治疗期间患者耐受性好,无明显不良反应.结论 1064 nm Q开关激光小光斑低能量治疗黄褐斑治疗次数少、疗效高、安全有效,可为黄褐斑治疗提供一种新方法.

abstractsObjective To evaluate the efficacy and experience of Q-switched laser with small light spot in the treatment of melasma.Methods Forty-six patients with melasma were emolled in study.Subjects received total of forty-six patients treatment with 1064 nm Q switched laser at one month intervals.Light spot of 3-4 nm were used.Results Forty-six patients completed the trial.The physician evaluation showed that 50％ of patients achieved 90％ to 100％ clearance,and 89.1％ patients achieved 60％ to 90％ clearance.Side effects was minimal and all the patients tolerated the treatment well.Conclusions Small light-spot and low-energy 1064 nm Q Switched laser is substantially effective and highly safe for the treatment of melasma.
