Depressed scars, which are unsightly outcomes of trauma or skin lesions, can lead to significant physical and mental stress. Various treatments have been developed to alleviate these burdens, among which the laser stacking method has proven effective. In this study, we compared the outcomes of laser stacking treatments with those of single-pulse ablative laser treatments for depressed scars. Eighty patients with depressed scars were divided into two therapeutic groups: the ablative laser stacking therapy group (Group 1, n = 40) and the single pulse ablative laser therapy group (Group 2, n = 40). The scars were evaluated using the modified Vancouver Scar Scale (mVSS) before and after treatment. Patient-completed questionnaires were also utilized. Comparative analyses were conducted both before and after treatment, as well as between the two groups. Eighty scars from each patient underwent the complete laser treatment protocols. Group 1 showed significantly greater improvement in the mVSS indices for pigmentation, vascularity, pliability, and height than group 2 (P < 0.05). In terms of patient-reported outcomes, group 1 rated better than group 2 across three indices: appearance, alleviation of concavity, and overall improvement (P < 0.05). Ablative laser stacking therapy effectively alleviated depressed scars, demonstrating significant improvement in both observer- and patient-reported outcomes. An energy level of 20-30 mJ was employed, resulting in more favorable outcomes compared to a single pulse laser application of 10-15 mJ. Our findings highlight the benefits of the stacking method, which shows notable improvements while minimizing complications. Further research involving various protocols may optimize clinical outcomes and patient satisfaction.
凹陷性瘢痕是创伤或皮肤损伤的难看后果，会导致严重的身心压力。人们已经开发出各种治疗方法来减轻这些负担，其中激光堆叠法已被证明是有效的。在本研究中，我们比较了激光堆叠治疗与单脉冲消融激光治疗凹陷性瘢痕的效果。80例凹陷性瘢痕患者被分为两个治疗组：消融激光堆叠治疗组（第1组，n = 40）和单脉冲消融激光治疗组（第2组，n = 40）。在治疗前后使用改良温哥华瘢痕量表（mVSS）对瘢痕进行评估。还使用了患者填写的问卷。在治疗前后以及两组之间进行了比较分析。每位患者的80处瘢痕都接受了完整的激光治疗方案。第1组在色素沉着、血管分布、柔韧性和高度的mVSS指数方面的改善明显大于第2组（P < 0.05）。在患者报告的结果方面，第1组在外观、凹陷减轻和总体改善这三个指标上的评分均高于第2组（P < 0.05）。消融激光堆叠疗法有效地减轻了凹陷性瘢痕，在观察者和患者报告的结果方面均显示出显著改善。采用了20 - 30 mJ的能量水平，与10 - 15 mJ的单脉冲激光应用相比，产生了更有利的结果。我们的研究结果突出了堆叠法的益处，该方法在显著改善的同时将并发症降至最低。涉及各种方案的进一步研究可能会优化临床结果和患者满意度。
