* * * Figure 5. A 2-year-old boy with PWS on V2 region, the photos at baseline (B), after 2 sessions of treatments (T2), after 5 sessions of treatments (T5), and after the last treatment (T9). The lesion developed fast at the beginning, so that the size at T2 was even larger than at baseline. The improvement score at T5 was 3(50-75%), and at Tfin was 4 (75-100%). * * * * Figure 8. Seventeen years old female with PWS on V1 and V2 region, the photos at baseline (B), after 1 session of treatments (T1), after 2 sessions of treatments (T2), after 3 sessions of treatments (T3), after 5 sessions of treatments (T5), and after the last treatment (T6). The improvement score at Tfin was 4 (75-100%). * * Figure 9. Fifty-one years old female with purple PWS on V2 region(no treatment to hairline), the photos at baseline (B), after 1 session of treatments (T1), after 3 sessions of treatments (T3), after 5 sessions of treatments (T5), after 7 sessions of treatments (T7), and after the last treatment (T8). The improvement score at T5 was 3(50-75%), and at Tfin was 4 (75-100%). * * 治疗前 6次治疗后1个月 Dual wave dye laser (595 1064) + fractionated laser (Active) * * 2013-12-12 T0 PWS 2014-5-20 T5P1M Dual wave dye laser (595 1064) , 4 times Dual wave dye laser (595 1064) + Fractionated laser, 1 time * * 皮损内的血管方向各异，有大量的垂直于皮面甚至和皮面呈斜角的血管。这些血管里的红细胞很难恰巧接受选择性激光的能量，更进一步将热量传导给血管内皮，是鲜红斑痣治疗抵抗的一个很重要的原因。因此，我们在双波长激光的基础上，叠加了非选择性的CO2点阵激光。点状的封闭血管。完成了对治疗区血管的进一步打击。 为比较CO2激光和双波长激光治疗的先后顺序，我们将皮损分区： 1区和3区先进行点阵激光的治疗；2区先进行双波长激光的治疗。 结果二者区别不大。 但患者疼痛感有很大区别。1.3区在刚刚擦掉表麻后治疗，对疼痛的忍耐性更好。 但CO2点阵激光治疗后，局部皮肤可能出现白色的小点（角质层空气），建议用生理盐水涂抹，促进消退。 * * * 痤疮的治疗原则从痤疮的成因出发认识：痤疮是各种因素综合作用的结果。毛囊皮脂腺角化异常和皮脂分泌过高是痤疮生成的两个基本成因，在此基础上合并痤疮丙酸杆菌生长及炎症反应，从而形成各种程度不同的痤疮。皮脂腺导管角化异常形成“角质拴”是痤疮病理生理的第一步。也是最重要的一步，痤疮的临床表现虽然形形色色，诱因也各不相同，但这一点却是无论如何变化都必须的一步，没有“角质拴”阻塞皮脂腺的开口，便不会形成粉刺进而形成痤疮。 * 因此，痤疮的治疗环节主要分为以下几个方面。 * * * * * * Titan 治疗前 2次治疗3个月后 2次治疗6个月后 治疗前 2次治疗3个月后 2次治疗6个月后 光嫩肤+2940点阵+近红外光 皮肤色素不均 老年斑 雀斑 鼻唇沟深 眼角下垂 面部下垂 治疗方法
