摘要
目的探讨Q开关Nd∶YAG激光治疗咖啡斑的临床疗效及副作用。方法应用Q开关Nd∶YAG激光仪治疗咖啡斑患者30例,波长1064nm,脉宽为3～7ns,光斑直径6mm,频率10Hz,能量密度为2.8～3.3 J/cm2,根据患者的病情选择适当的治疗参数,光斑照射到皮损表面后皮肤呈红色为参数适度。7～10 d治疗1次,治疗7～10次。结果痊愈6例,显效12例,好转9例,无效3例,总有效率达60.0%。无色素沉着及瘢痕形成。结论 Q开关Nd∶YAG激光治疗咖啡斑疗效确切,副作用小,安全性高。
Objective To explore the clinical effect of MedliteC6 Q-switched Nd ∶YAG 1064nm laser irradiation treatment on café-au-lait spots. Methods Thirty café-au-lait spots patients were treated with Q-switched Nd ∶YAG laser in our department,and the parameters of laser therapy were as follows： wavelength 1 064 nm,wave width 3 to 7 ns,light spot diameter 6 mm,frequency 10 Hz,and energy 2.8 to3.3 J/cm2.We chose the proper parameters of laser to treat the patients according to the index skin character,and then the laser was irradiated to the involving skin.The treated skin turning red was thought to be proper endpoint after several times of treatment. Results All of the patients were successfully treated by 7 to 10 times of laser irradiation without severe complications.Among the 30 patients,the cured,effective,clinically improved and ineffective cases were 3,6,9 and12,and the effective rate was 60% without hyperpigmentation or scar formation case. Conclusions Q-switched Nd ∶YAG 1 064 nm laser therapy is an effective and safe treatment to café-au-lait spots.
