Successful treatment of acne scars in ethnic skin requires procedures that are safe and effective with a low incidence of hyper or hypopigmentation postoperatively.
In this study, the safety and efficacy of a combined treatment protocol including tumescent anesthesia, subcision, trichloracetic acid peel, and fractional erbium laser resurfacing was evaluated.
This is a retrospective study of 56 patients (22 women and 34 men) with predominantly rolling acne scars and Fitzpatrick skin Types IV-VI who were treated using a combination of tumescent anesthesia, extensive subcision, fractional ablative erbium laser, and a blending 20% trichloracetic acid (TCA) peel.
The mean improvement after a single treatment, assessed by 3 independent evaluators (2 dermatologist and 1 dermatology physician assistant), was 2.52 (SD = 1.04) on a scale of 1 to 4.
The combination of tumescent anesthesia, extensive subcision, fractional ablative erbium laser resurfacing, and a blending 20% TCA peel (combined procedure) is both safe and effective in the treatment of rolling acne scars in ethnic skin types with acceptable temporary adverse effects.
成功治疗有色人种的痤疮疤痕需要安全且有效的程序，术后色素沉着过度或不足的发生率要低。
本研究评估了包括肿胀麻醉、皮下分离术、三氯乙酸（TCA）剥脱术和铒激光微剥脱术联合治疗方案的安全性和疗效。
这是一项回顾性研究，共纳入 56 例（22 名女性和 34 名男性）主要为滚动型痤疮疤痕和 Fitzpatrick 皮肤类型 IV-VI 的患者，采用肿胀麻醉、广泛皮下分离术、铒激光微剥脱术和 20%三氯乙酸（TCA）混合剥脱术联合治疗。
3 名独立评估者（2 名皮肤科医生和 1 名皮肤科医生助理）评估单次治疗后的平均改善程度为 2.52（SD=1.04），评分范围为 1 至 4。
肿胀麻醉、广泛皮下分离术、铒激光微剥脱术和 20%TCA 混合剥脱术（联合治疗）联合治疗在治疗有色人种的滚动型痤疮疤痕方面是安全且有效的，具有可接受的暂时不良反应。
