Keloids and other scars are different manifestations of the normal wound healing process. If located in visible areas, scars may have a psychological impact that could affect the quality of life of the scar-bearing population. Good preoperatory planning including hiding incisions in natural anatomical landmarks or placing them parallel to relaxed skin tension lines are among the techniques used to improve the cosmesis of scars. Once a prominent or noticeable scar has developed, multiple therapeutic modalities can be applied including surgical excision, although high recurrence rates precludes its use as monotherapy. Several advanced surgical correction techniques including Z-plasty and W-plasty may be useful in repositioning scars. Other modalities that have been reported to improve scar cosmesis include cryosurgery, radiotherapy, lasers, and skin substitute grafts. Adjuvant postsurgical treatment modalities have reduced dramatically the recurrence rates associated with the removal of the scar. In this review of the literature the authors discuss evidence based data related to the abovementioned modalities and other topical and intralesional therapies including occlusion, compression, silicone, corticosteroids, interferons, imiquimod, resiquimod, tacrolimus, 5-fluorouracil, retinoids, as well as the role of several over-the-counter agents such as onion extract, vitamin E and the combination of hydrocortisone, vitamin E and silicone. Finally, they address newer modalities including vascular endothelial growth factor inhibitor, transforming growth factor-3, interleukin-10, mannose-6-phosphate, UVA-1, narrowband UVB, intense pulsed light and photodynamic therapy. Ultimately, the decision of choosing the most appropriate postexcisional management treatment should be taken by physicians on a case-by-case basis in order to obtain the best cosmetically acceptable results.
瘢痕疙瘩和其他瘢痕是正常伤口愈合过程的不同表现形式。如果瘢痕位于可见部位,可能会产生心理影响,进而影响有瘢痕人群的生活质量。良好的术前规划,包括将切口隐藏在自然解剖标志处或使其与皮肤松弛张力线平行,是用于改善瘢痕美观的技术之一。一旦形成明显或引人注目的瘢痕,可应用多种治疗方式,包括手术切除,不过高复发率使其不能作为单一疗法使用。几种先进的手术矫正技术,如Z成形术和W成形术,可能有助于重新定位瘢痕。据报道,其他改善瘢痕美观的方式包括冷冻手术、放射治疗、激光和皮肤替代移植。辅助性术后治疗方式已大幅降低了与瘢痕切除相关的复发率。在这篇文献综述中,作者讨论了与上述方式以及其他局部和病灶内治疗相关的循证数据,这些治疗包括封闭、压迫、硅酮、皮质类固醇、干扰素、咪喹莫特、瑞喹莫特、他克莫司、5-氟尿嘧啶、维甲酸,以及几种非处方药物如洋葱提取物、维生素E和氢化可的松、维生素E与硅酮组合的作用。最后,他们探讨了更新的治疗方式,包括血管内皮生长因子抑制剂、转化生长因子-3、白细胞介素-10、甘露糖-6-磷酸、UVA-1、窄谱中波紫外线、强脉冲光和光动力疗法。最终,选择最合适的切除后管理治疗方案应由医生根据具体情况做出决定,以便获得最佳的美容可接受效果。
