病理性瘢痕的光电治疗研究进展(3)
5小结
近年来,国内外文献及较多临床实践已证实,光电技术能有效预防瘢痕形成及治疗瘢痕,且创伤小、不良反应小,值得临床推广使用。但在选择光电治疗时应因瘢痕而异:PDL、IPL、532 nm KTP及点阵1 550 nm铒玻璃激光对血管增生、扩张明显的PS有效,且前二者对术后早期(4周内)瘢痕有更好地治疗效果,532 nm KTP治疗易出现疼痛不适及导致色素沉着,耐受力差及肤色深患者慎选;长脉宽Nd:YAG 1 064 nm激光、点阵CO2激光适用于较厚的瘢痕,前者还适用于有较深、粗大血管及颜色深的瘢痕;点阵2 940 nm铒激光、MPT适用于表浅性瘢痕和凹陷性瘢痕,其中,MPT色素沉着风险更小,但易有疼痛不适,治疗时需做好麻醉工作。不同光电技术均有其特点,如何根据瘢痕的特点及患者的不同需求来优化选择,还值得临床继续研究探讨。
