[摘 要] 皮肤受到损伤时，机体会启动修复机制，其中包括炎症反应、细胞增殖以及组织重塑等过程，会因胶原纤维大规模生成及细胞外基质的过度积累，而造成瘢痕疙瘩的出现。瘢痕疙瘩的形成不仅影响皮肤美观，还会引发诸如疼痛、瘙痒、紧绷感等功能障碍。而激光治疗具有微创、术后康复时间短和明显改善瘢痕外观的优势，已广泛应用于临床治疗。然而，将激光单独应用于瘢痕疙瘩的临床治疗中，却始终存在一定的局限性，鉴于此，本文将围绕不同激光技术在治疗瘢痕疙瘩中的应用展开论述，以期为进一步提升瘢痕疙瘩治疗的安全性和有效性提供参考。

    [Abstract] When the skin is damaged， the body will start the repair mechanism， including inflammatory response， cell proliferation and tissue remodeling， which will cause the appearance of keloids due to the large-scale formation of collagen fibers and the excessive accumulation of extracellular matrix. The formation of keloids not only affects the appearance of the skin， but also causes dysfunctions such as pain， itching， and tightness. Laser therapy has the advantages of minimally invasive， short postoperative recovery time and obvious improvement of scar appearance ......
