目的　探讨瘢痕整形对比点阵CO₂激光对烧伤后患者美容效果的影响。方法　选取2021年2月—2024年2月收诊的50例深度烧伤后需进行整形的患者,采用随机数字表法分为对照组与观察组,每组各25例。给予观察组瘢痕整形治疗,给予对照组点阵CO₂激光治疗。观察不同时间节点两组患者温哥华瘢痕量表（VSS）评分情况,观察并对比两组瘢痕增生情况,并记录两组治疗期间出现的不良反应。结果　截止末次随访时间（治疗后6个月）,本次研究纳入50例患者均得到随访,随访期间未见脱落、失访病例。两组VSS评分随时间呈下降趋势,治疗后不同时间节点VSS评分差异有统计学意义（P<0.05）,不同治疗方案和时间对VSS评分有交互作用（P<0.05）;观察组的轻度增生人数多于对照组,中度增生与重度增生人数少于对照组（P<0.05）,满意率高于对照组（P<0.05）。两组患者创面感染、红肿及疼痛等情况发生率均较低,观察组的创面感染风险及红肿、疼痛等发生率与对照组间差异无统计学意义（P>0.05）。结论　瘢痕整形相较点阵CO₂激光治疗能更加有效改善烧伤后患者的美容效果,并减少瘢痕增生的程度。

Objective To evaluate the effects of scar plastic surgery versus dot matrix CO₂ laser on the cosmetic outcomes of burn patients. Methods A total of 50 patients with deep burns requiring plastic surgery, who were admitted between February 2021 and February 2024, were selected and randomly divided into a control group and an observation group using a random number table, with 25 cases in each group. The observation group received scar plastic surgery treatment, while the control group received dot matrix CO₂ laser therapy. The Vancouver Scar Scale （VSS） scores of both groups at different time points, scar hyperplasia, and adverse reactions during the treatment were recorded and compared between the two groups. Results By the end of the last follow-up （6 months after treatment）, all the 50 patients included in this study were followed up, and there were no cases of drop-out or loss to follow-up. The VSS scores of the two groups showed a downward trend over time, and there were significant differences in VSS scores at different time points after treatment （P<0.05）. Different treatment schemes and time had interactive effects on VSS scores （P<0.05）. The number of mild hyperplasia in the observation group was more than that in the control group, while the numbers of moderate and severe hyperplasia in the observation group were less than those in the control group （P<0.05）. The satisfaction rate in the observation group was higher than that in the control group （P<0.05）. The incidence rates of wound infection, redness, and pain in both groups of patients were low, and the rates were not different between the two groups （P>0.05）. Conclusion Scar plastic surgery is more effective in improving the cosmetic outcomes of burn patients and reducing the degree of scar hyperplasia than dot matrix CO₂ laser treatment.
