目的 观察Q开关Nd∶YAG激光治疗颧部褐青色痣的疗效及不良反应。方法 用波长为倍频 53 2nm ,光斑 3 .0mm ,脉宽 5~ 10ns ,能量密度 1.6~ 1.8J/ 2 ,脉冲频率 5~ 10Hz治疗 3 50例 ,术后 3~ 6个月复诊 ,根据术前照片判定疗效 ,标准分Ⅳ级。结果 治疗次数最少 1次 ,最多 5次 ,共治愈13 3例 ( 3 8.0 % ) ,平均治愈次数 2 .1次 ,总有效率 82 .0 % ,疗效与治疗次数成正相关。结论 Q开关Nd∶YAG激光波长为倍频 53 2nm对颧部褐青色痣有很好疗效 ,一般治疗 2~ 4次可基本痊愈。术后除部分病例色素沉着外 。
Objective To observe the therapertic effect and side-e ff ect of Q-switched Nd∶YAG laser irradiation in the treatment of nevus Fusco- Caeruleus zygomaticus (NFZ). Methods A total of 350 cases were treated with 532nm wave length laser; the diameter of therapy spot was 3.0mm, p ulse duration was 5~10ns, and energy density was 1.6~1.8 J/㎝ 2. The therape utic effects were judged by comparision of the photograph before operation with that after treatment for 3~6 months. The judgement standards of therapeutic eff ect were classified into 4 grades.Results The time of therapy r anged from 1 to 5 (average 2.14). The number of cure was 133 cases (38.00 %). Th e therapeutic effect was positively related to the times of therpy. Conc lusion The 532nm wave length of Q-switch Nd∶YAG laser has fairly good therapeatic effect on NFZ. Generaly, the time of cure is 2~4. There is almost no other side-effect except hyperpigmentation in some cases.
