点阵激光在瘢痕防治中的应用进展

Application of fractional lasers in the prevention and treatment of scars

点阵激光单独应用或联合其他方法治疗浅表性瘢痕、萎缩性瘢痕、增生性瘢痕及瘢痕疙瘩均有不同程度的改善,偶有加重.点阵激光可减少早期创伤、手术瘢痕发展成增生性瘢痕的机会.其疗效与瘢痕类型、治疗参数的选择、皮肤类型、术后护理等有关.点阵激光的不良反应主要为暂时性或持久性红斑、炎症后色素沉着、疼痛、水泡、结痂、感染等,常较轻或一过性,遗留永久性和严重并发症较为少见,偶可出现瘢痕增生.

Fractional lasers alone or in combination can improve superficial scars, atrophic scars, hyperplastic scars and keloids to different degrees, but occasionally aggravate the condition.They can effectively reduce the possibility that early-stage trauma or surgical scars develop into hyperplastic scars.The therapeutic effect of fractional lasers is associated with the type of scars, treatment parameters, Fitzpatrick skin types, postoperative care, etc.The main adverse reactions of fractional lasers include temporary or persistent erythema, post-inflammatory hyperpigmentation, pain, blisters, crusts, infections, etc.These adverse reactions are usually slight or temporary, and permanent or serious complications rarely occur, but hyperplastic scars occasionally form.
