目的 探讨 1 565 nm非剥脱点阵激光联合硅凝胶对头面部急诊外伤后早期瘢痕修复中的临床疗效。 方法 随机选取自2021年9月至 2022年 12 月于本院就诊的80例头面部急诊外伤后早期瘢痕干预患者作为研究对象，随机分为两组，于术后分别给予硅凝胶应用、1 565 nm非剥脱点阵激光+硅凝胶治疗应用。每位患者均需要接受6次治疗，每次治疗之间的间隔为1个月。为了评估治疗的有效性，我们将在治疗前后两周，使用PSAS、OSAS和VSS三种量表，对患者的疗效进行评估。记录患者的满意度和治疗结果，并评估可能出现的副作用。 结果 两组分别有40例患者，通过对两组患者的PSAS、OSAS和VSS的对比研究，我们发现在治疗后两组的各项评分均较治疗前有所降低（P < 0.05），治疗后观察组的评分低于对照组的评分（P < 0.05）。经过比较，对照组的满意度为62.50%，而观察组的满意度却达到了87.50%。在观察组中，存在2例患者出现了色素沉着，1例患者表示疼痛。其余患者正常。 结论 经过研究发现，硅凝胶和1 565 nm非剥脱点阵激光均可以改善头面部急诊外伤患者的瘢痕，其中1 565 nm非剥脱激光的改善作用得到肯定，且副作用较小。

Objective To examine the effectiveness of a 1 565 nm non-ablative fractional laser combined with silicone gel in the early repair of scarring following head and face emergency trauma. Methods Randomly selecting 80 cases of early scar intervention patients who had experienced head and face emergency trauma at our hospital from September 2021 to December 2022 as research objects， we divided them into two groups and administered silicone gel application， as well as 1 565 nm Non-ablative fractional laser + silicone gel treatment. Each patient received 3 treatments with a 1-month interval between each treatment. Patients in two groups， each with 40 participants， were evaluated with the Patient Assessment Scale （PSAS）， Observer Assessment Scale （OSAS）， and the new Vancouver Scar Scale （VSS） prior to and two weeks after the last treatment. Results The results were documented in terms of patient satisfaction and adverse reactions during the treatment. We discovered that the PSAS， OSAS and VSS scores of the two groups of patients were lower post-treatment （P < 0.05） than before （P < 0.05）. The control group score was also lower than the control group （P < 0.05）. The control group satisfaction was 62.50%， while the observation group was 87.50%. The observation group was comprised of 2 individuals with pigmentation and 1 with pain， while the remainder were healthy. These two groups had distinct side effects. Conclusion It is found that both silicone gel and 1 565 nm non-ablative fractional laser can improve the scars of head and face emergency trauma patients， and the improvement effect of 1 565 nm non-ablative laser is affirmed， and the side effects are relatively small.
