The purpose was to evaluate the clinical outcomes of laser skin resurfacing using an ultra-pulse carbon dioxide (CO) laser and manual dermabrasion with a medium-grit drywall sand screen for scar revision in adults with Fitzpatrick skin type III to V.
A total of 20 postsurgical and post-traumatic scars in individuals with Fitzpatrick skin type III to V were included in this study. Preoperative evaluation of the scars was performed by 3 blinded observers using the Manchester scar rating scale. Each scar to be treated was divided into 2 equal halves, and each half was randomly allotted to either ultra-pulse CO laser resurfacing (group A) or manual dermabrasion (group B). Postoperative clinical evaluation was performed by the same observers using the Manchester scar rating scale at the end of the first month, third month, and sixth month.
This study showed that both methods were effective in improving the appearance of the postsurgical and post-traumatic scars. No significant difference was found between them (P = .978). Hyperpigmentation occurred in 4 scars in both the half treated with manual dermabrasion and the half treated with laser resurfacing; however, it had resolved by the end of the sixth month in all 4 scars.
CO laser resurfacing and manual dermabrasion are equally efficacious and safe methods for scar resurfacing in adults with Fitzpatrick skin type III to V.
本研究旨在评估使用超脉冲二氧化碳(CO)激光进行皮肤磨削术以及使用中粒度干墙砂筛进行手动磨皮术对 Fitzpatrick III 至 V 型皮肤的成人瘢痕修复的临床效果。
本研究纳入了 20 例 Fitzpatrick III 至 V 型皮肤个体的术后及创伤后瘢痕。3 名盲法观察者使用曼彻斯特瘢痕评定量表对瘢痕进行术前评估。将每个待治疗的瘢痕分成两个相等的部分,每部分随机分配至超脉冲 CO 激光皮肤磨削术(A 组)或手动磨皮术(B 组)。在术后第 1 个月、第 3 个月和第 6 个月,由相同的观察者使用曼彻斯特瘢痕评定量表进行术后临床评估。
本研究表明,两种方法在改善术后及创伤后瘢痕外观方面均有效。两者之间未发现显著差异(P = 0.978)。手动磨皮术治疗的一半瘢痕和激光皮肤磨削术治疗的一半瘢痕中均有 4 个瘢痕出现色素沉着;然而,所有 4 个瘢痕在第 6 个月末色素沉着均已消退。
对于 Fitzpatrick III 至 V 型皮肤的成人,CO 激光皮肤磨削术和手动磨皮术是同样有效且安全的瘢痕修复方法。
