摘要
目的:观察Q开关Nd:YAG激光治疗颧部褐青色痣的临床疗效及不良反应。方法:应用Q开关Nd:YAG激光治疗280例患者,波长为1064nm,光斑直径3～4mm,能量密度9～11J/cm2,脉宽10ns。术后3～6个月复诊,根据术前术后照片判定疗效,标准分为Ⅳ级。结果:治疗1～5次,间隔时间3～12个月,共治愈107例(38.2%),平均治疗次数2.7次,总有效率77.9%,疗效与治疗次数成正相关。术后色素沉着152例(54.3%)。结论:Q开关Nd:YAG激光治疗颧部褐青色痣效果满意,虽然术后色素沉着发生率较高,但均能随时间逐渐消退,未见其他不良反应及并发症。
Objective To observe the therapeutic effect and side effect of Q-switched Nd：YAG laser irradiation on naevus fuscocaeruleus zygomaticus （NFZ）. Methods A total of 280 cases were treated with 1 064nm wave length laser.The diameter of therapy spot was 3-4mm, pulse duration was 10ns,and energy density was 9-11 J/cm^2. The therapeutic effect was judged according photograph took before treatment and 3-6 months after treatment. The judgment standards of therapeutic effect were classified into IV grades. Results The therapeutic times ranged from 1-5.The interval of therapy was 3-12 months.107 cases （38.2%） were cured, and the average times of cure were 2.7.The total effective rate was 77.9%, and the therapeutic effect was positively related with therapeutic times.Hyperpigmentation was observed in 152 cases （54.3%）. Conclusion Q-switched Nd＇YAG laser has fairly good therapeutic effect on naevus fuscocaeruleus zygomaticus.There is almost no other side effect except the high occurring of hyperpigmentaion,and it is cleaned up slowly.
