308nm准分子激光治疗白癜风皮肤病进展

Advances in Vitiligo Treatment by 308 nm Excimer Laser

临床研究表明波长308 nm准分子激光治疗白癜风皮肤病效果明显。治疗效果与病人的性别、年龄、病程没有明显关联,但与皮肤类型、皮损部位、治疗频度和疗程等有明显关联。在一定剂量范围内随治疗剂量和治疗时间增加治疗效果越来越明显,呈线性变化。而皮损部位的影响,疗效从明显到不明显的顺序是:面部,颈部和头皮,生殖器,四肢,躯干,手脚或肢端关节。皮肤类型对治疗效果影响明显。另外,在一定的观察时间内发现308 nm准分子激光疗效明显高于NB UVB。

This study is a retrospective review of the clinical efficacy of 308 nm excimer laser in vitiligo treatment. Clinical studies have reported that 308 nm excimer laser shows effective treatment of vitiligo. The treatment efficacy has showed no obvious correlation with the patients＇ sex, ageand course of disease, but obviously correlated with skin type, skin lesions, treatment frequency and duration. The treatment efficacy increased linearly with the dose and duration of treatment in a certain dose range. The treatment response showed anatomical preferences, in a decline order of face, neck, scalp, genitals, limbs, trunk, extremities joints. Another factor on the efficacy was skin type. In addition, 308 nm excimer laser treatment appears to be more effective than NB UVB phototherapy in a certain observation period.
