Objective To observe the clinical curative effect analysis of Q switch laser for nevus fuscoceruleus. Methods 120 cases with facial nevus fuscoceruleus patients in our hospital from June 2012 to September 2015, were randomly divided into two grou the observation group with wavelength 1064nm treatment, pulse frequency 10-15Hz, energy density 4-5.5/cm2, spot diameter 3-4mm; control group with the wavelength of 532nm, pulse frequency 2.5-4Hz, energy density 1.8-21J/cm2, spot diameter 2-3mm, the clinical effects of different treatment times, compared the treatment efficacy and adverse reactions of the two groups were detected. ps, Results The better curative effect more times of treatment; the treatment efficiency of observation group was significantly better than the control group (P<0.05), no statistical significance two groups of patients with adverse reactions difference (P>0.05). Conclusion The treatment of Q switch laser for the treatment of nevus, the longer the wavelength, the more the number of treatment, the more obvious the effect, and its side effects are small, no scar, worthy of clinical application.%目的:观察分析不同波长调Q激光对褐青色痣的临床疗效.方法:选取笔者科室2012年6月-2015年9月收治的120例面部褐青色痣患者,随机分为两组.观察组:采用波长1064nm调Q激光治疗,脉冲频率10~15Hz,能量密度4~5.5/cm2,光斑直径3~4mm;对照组:采用波长532nm调Q激光,脉冲频率2.5~4Hz,能量密度1.8~21J/cm2,光斑直径2~3mm,分析不同治疗次数的临床疗效,比较两组患者的治疗有效率及不良反应发生情况.结果:治疗次数越多,疗效越好;观察组治疗有效率明显优于对照组(P<0.05),两组患者不良反应情况差异无统计学意义(P>0.05).结论:不同波长调Q激光治疗褐青色痣,其波长越长、治疗次数越多,效果越明显,同时其副作用小,不产生瘢痕,值得临床推广应用.
