黄褐斑激光治疗有用吗 [Pixel激光治疗黄褐斑的疗效和安全性分析]

　　[摘要]目的:评估Pixel激光治疗黄褐斑的疗效及安全性。方法:采用Pixel激光治疗黄褐斑患者72例,3～4周治疗1次,3～5次为一个疗程,每次复诊由医生和患者共同评定疗效和安全性。结果:72例患者中,痊愈17例(23.61%),显效18例(25.0%),有效率48.61%。轻度组:痊愈率45.45%(15例),显效率36.36%(12例),有效率81.81%;重度组:痊愈率5.13%(2例),显效率15.38%(6例),有效率20.51%;两组比较有显著性差异。病程小于2年者,有效率68.42%,疗效高于病程大于2年者。21例患者术后出现轻度色素沉着,均于术后3个月消退。结论:Pixel激光治疗黄褐斑安全有效,病程短、颜色浅者疗效更佳。
