0fficacy of melasma treated by Q-switch Nd:YAG laser

目的:观察Q开关Nd:YAG激光治疗黄褐斑的疗效。方法:应用Medlite C6激光治疗仪(美国HOYA-ConBio公司生产),波长1064nm,光斑大小6mm,能量2.5～3.5J/cm2,治疗120例黄褐斑患者,每周一次,共治疗10次,观察临床疗效及副作用。结果:120例患者经过治疗后,43例(35.8%)完全消退,68例(56.7%)明显消退,总有效率为92.5%。所有患者均述面部治疗区域皮肤质地较以前更光滑、细腻,无严重不良反应出现。结论:采用MedliteC6 1064nm大光斑、低能量治疗黄褐斑疗效显著、安全,副作用少。

Objective To investigate the efficacy of melasma treated by Medlite C6 Q-switch Nd：YAG laser.Methods 120 melasma outpatients were treated by Medlite C6 Q-switch Nd：YAG laser with 1064nm wavelength,6mm spot,2.5～3.5J/cm2 energy.The clinic efficacy and adverse effect were recorded.Results Among the 120 patients,43 cases（35.8%） with melasma were disappeared completely,68 cases（56.7%） regression obviously.The total efficient rate reached 92.5%.All patients skins feeled more better texture,smooth than that before treatment.No severe adverse reactions were seen.Conclusions Medlite C6 Q-switch Nd：YAG laser with low energy and large spot is an effective and safe option for the treatment of melasma.
