Lux1540nm fractional laser treatment for superficial scar

目的观察非剥脱性点阵激光Luxl540nm治疗浅表性瘢痕的临床疗效。方法根据Fitzpatrik皮肤分型以及瘢痕性状，选择不同的能量和脉宽治疗浅表性瘢痕32例，术后6个月浅表性瘢痕表观和术前数码照相对照评定其疗效及不良反应。结果本组32例中有效25例（78．12％），无效7例（21．88％）；随着治疗次数增多，疗效逐渐提高。术后短暂的红斑在治疗后4～24h消失；一过性色素沉着3例（9．38％），3～6个月消退。结论非剥脱性点阵激光Luxl540nm对浅表性瘢痕疗效较好，不良反应小。

Objective To observe the effect of non-ablative fractional laser Lux1540nm in superficial scars therapy. Methods According to the Fitzpatrik skin type and scar appearances, appropriate laser energy and pulse width were selected for scar treatment. Therapeutic effect and side-effect was evaluated by preoperative photos and 6 months of postoperative photos. Results The total effective rate was 78. 12% （28/32）. 7eases （ 21.88% ） showed ineffective results. The therapeutic effect was improved along the increase of treatments. Temporary hyperpigmentation was found in 3 cases （9.38%） and faded away within 3-6 months. Temporary erythema faded away within 4-24 hours. Conclusion The treatment of non-ablative fractional laser Lux1540nm for superficial scar is effective with minimum side effect.
