Facial scars can develop as a result of trauma, surgery, burns, acne, or other conditions. These scars are often quite distressing to patients. Lasers were first used to treat these scars in the 1990s. Recently, new laser technology has been used to prevent and treat scars. This literature review and the report of the senior author's recent experience summarize the recent advances in laser treatment of scars.
With the development of new laser technology, the treatment options for hypotrophic scars and developing scars have increased. Furthermore, there are expanded options for treatment of established hypertrophic scars. Recent studies have shown that nonablative and fractionated lasers can be effective for treating hypotrophic and developing scars. Scar improvements may be due to direct effects of the laser and/or histochemical effects, including production of heat shock proteins and tumor growth factors. Nonablative and fractionated lasers have a shorter recovery period than CO2 resurfacing lasers. This can vary from a few hours to up to 7 days.
Recent new laser technology has increased the options for treatment of scars. These have been shown to be beneficial for hypotrophic, incipient, and established scars. The benefits of laser therapy may be due to direct and/or histochemical effects.
面部瘢痕可因外伤、手术、烧伤、痤疮或其他情况而形成。这些瘢痕常常给患者带来很大困扰。激光在20世纪90年代首次用于治疗这些瘢痕。最近，新的激光技术已被用于预防和治疗瘢痕。这篇文献综述以及资深作者近期经验的报告总结了激光治疗瘢痕的最新进展。
随着新激光技术的发展，对萎缩性瘢痕和正在形成的瘢痕的治疗选择有所增加。此外，对于已形成的增生性瘢痕也有了更多的治疗选择。最近的研究表明，非剥脱性和分次激光可有效治疗萎缩性和正在形成的瘢痕。瘢痕改善可能归因于激光的直接作用和/或组织化学作用，包括热休克蛋白和肿瘤生长因子的产生。非剥脱性和分次激光的恢复期比二氧化碳磨皮激光短。恢复期从几小时到长达7天不等。
最近的新激光技术增加了瘢痕的治疗选择。这些已被证明对萎缩性、初期和已形成的瘢痕有益。激光治疗的益处可能归因于直接和/或组织化学作用。
