BACKGROUND Hypertrophic scars from severe burns cause physical and psychological stress. Proper treatment, including CO₂ laser systems, can alleviate these burdens by enabling skin remodeling and collagen production. This study assessed the efficacy of a new laser device with 2 wavelengths (10 600 nm/1540 nm) and 2 scanning units on hypertrophic burn scar management. CASE REPORT A 34-year-old African woman sought treatment for a large hypertrophic burn scar on her right foot. The scar, formed at age 9, was complicated by infection. She underwent 2 CO₂ sessions (Scar3 scanner), followed by 3 cycles of fractional CO₂ +1540 nm laser (µScan DOT scanner) once a month, combined with topical hyaluronic acid. She also had 2 maintenance sessions with a 595-nm dye laser to prevent scar reactivation. The CO₂ and 1540 nm laser synergy improved laxity through volumetric thermal effects, causing contraction and stimulation. This led to a softer, smaller scar with less consistency. The patient experienced significant improvement in quality of life due to alleviation of pain and restored footwear comfort. CONCLUSIONS The hypertrophic burn scar was effectively treated using 10 600 nm and 1540 nm wavelengths, along with dye laser treatment for recurrence prevention.
严重烧伤引起的增生性瘢痕会造成身体和心理负担。适当的治疗，包括 CO₂ 激光系统，可以通过皮肤重塑和胶原蛋白生成来缓解这些负担。本研究评估了一种新的激光设备，该设备具有 2 个波长（10600nm/1540nm）和 2 个扫描单元，用于治疗增生性烧伤瘢痕。
一位 34 岁的非洲女性因右脚的大面积增生性烧伤瘢痕寻求治疗。该瘢痕于 9 岁时形成，合并感染。她接受了 2 次 CO₂ 治疗（Scar3 扫描仪），随后每月进行 3 次分数 CO₂+1540nm 激光（µScan DOT 扫描仪）治疗，同时外用透明质酸。她还进行了 2 次 595nm 染料激光维持治疗，以防止瘢痕再激活。CO₂ 和 1540nm 激光的协同作用通过体积热效应改善了松弛度，导致收缩和刺激。这使得瘢痕变得更软、更小，质地更均匀。患者的生活质量显著改善，疼痛减轻，穿着更舒适。
通过使用 10600nm 和 1540nm 波长以及染料激光治疗来预防复发，有效地治疗了增生性烧伤瘢痕。
