In recent years, fractional ablative lasers at low density have proven to be the centerpiece in a multimodality approach to treating hypertrophic burn scars.
To determine the safety and efficacy of fractional ablative erbium-doped yttrium aluminium garnet (Er:YAG) laser in the treatment of hypertrophic burn scars.
Eleven patients received 3 fractional ablative Er:YAG laser to hypertrophic burn scars at 400 to 800 μm, density 11%, no coagulation, and single pass at 4-week intervals.
Overall, average improvement was noted to be 2.27 of 3 as determined by blinded observers. A significant improvement was noted in all measured parameters including dyschromia, atrophy hypertrophy, vascularity, and texture.
This is a pilot study showing the safety and efficacy of fractional ablative Er:YAG laser treatment is a safe and effective treatment modality in the treatment of hypertrophic scars.
近年来，低密度的分数消融激光已被证明是治疗增生性烧伤瘢痕的多模态方法的核心。
确定分数消融铒石榴石激光（Er:YAG）治疗增生性烧伤瘢痕的安全性和有效性。
11 例患者接受 3 次分数消融 Er:YAG 激光治疗，激光波长 400-800μm，密度 11%，无凝固，间隔 4 周单次通过。
根据盲法观察者的评估，整体平均改善为 3 分之 2.27。所有测量参数均有显著改善，包括色素沉着异常、萎缩性肥大、血管生成和质地。
这是一项初步研究，表明分数消融铒石榴石激光治疗是一种安全有效的增生性瘢痕治疗方法。
