Restoration of form and function after burn injury remains challenging, but emerging laser and pulsed light technologies now offer hope for patients with hypertrophic scars, which may be associated with persistent hyperemia, chronic folliculitis, intense pruritis, and neuropathic pain. In addition to impairing body image, these scars may limit functional recovery, compromise activities of daily living, and prevent return to work. Three different platforms are now poised to alter our reconstructive algorithm: (1) vascular-specific pulsed dye laser (PDL) to reduce hyperemia, (2) ablative fractional CO(2) laser to improve texture and pliability of the burn scar, and (3) intense pulsed light (IPL) to correct burn scar dyschromia and alleviate chronic folliculitis. In this paper, we will provide an overview of our work in this area, which includes a systematic review, a retrospective analysis of our preliminary experience, and interim data from our on-going, prospective, before-after cohort trial. We will demonstrate that laser- and light-based therapies can be combined with each other safely to yield superior results, often at lower cost, by reducing the need for reconstructive surgery. Modulating the burn scar, through minimally invasive modalities, may replace conventional methods of burn scar excision and yield outcomes not previously possible or conceivable.
烧伤后形态和功能的恢复仍然具有挑战性,但新兴的激光和脉冲光技术现在为患有增生性瘢痕的患者带来了希望,增生性瘢痕可能与持续性充血、慢性毛囊炎、剧烈瘙痒和神经性疼痛有关。除了损害身体形象外,这些瘢痕还可能限制功能恢复、影响日常生活活动并阻碍重返工作岗位。现在有三种不同的平台有望改变我们的重建算法:(1)血管特异性脉冲染料激光(PDL)以减轻充血,(2)剥脱性分数CO2激光以改善烧伤瘢痕的质地和柔韧性,以及(3)强脉冲光(IPL)以纠正烧伤瘢痕色素沉着异常并减轻慢性毛囊炎。在本文中,我们将概述我们在该领域的工作,包括一项系统综述、对我们初步经验的回顾性分析以及我们正在进行的前瞻性前后队列试验的中期数据。我们将证明,基于激光和光的疗法可以安全地相互结合,通过减少重建手术的需求,通常以更低的成本产生更好的效果。通过微创方式调节烧伤瘢痕可能会取代传统的烧伤瘢痕切除方法,并产生以前不可能或无法想象的结果。
