Acne scars are extremely disturbing to patients, both physically and psychologically. This study assessed the safety and efficacy of the erbium:yttrium-aluminum-garnet (Er:YAG) laser on acne scars.
To evaluate the clinical effects of resurfacing atrophic facial acne scars with the Er:YAG laser in the Turkish population.
A total of 128 patients, aged 22-42 years, underwent laser resurfacing. The patients had Fitzpatrick skin types ranging from II to V. Photographs were taken before and 3 months after treatment. Results were evaluated for the degree of clinical improvement, pigmentary change, and any adverse events.
Clinical improvements in facial skin texture, acne scarring and dyschromia were noted in all patients. There was a 50.2% average clinical improvement. Complete wound healing occurred between 6 and 8 days. Erythema occurred in all patients and lasted longer than 3 months in five patients (3.9%). Post-inflammatory hyperpigmentation occurred in nine patients (7%) and lasted longer than 3 months in one patient (0.8%). No patient experienced hypopigmention. Mild to moderate postoperative acne flare-up occurred in 14 patients (11%). No other adverse effects were observed.
Er:YAG laser resurfacing is a safe and effective treatment modality for facial acne scars in the Turkish population who have darker skin tones.
痤疮疤痕在生理和心理上都给患者带来极大困扰。本研究评估了铒：钇铝石榴石（Er:YAG）激光治疗痤疮疤痕的安全性和有效性。
评估在土耳其人群中使用Er:YAG激光对萎缩性面部痤疮疤痕进行表面重塑的临床效果。
共有128例年龄在22至42岁之间的患者接受了激光表面重塑治疗。患者的菲茨帕特里克皮肤类型为II至V型。在治疗前和治疗后3个月拍摄照片。对临床改善程度、色素变化和任何不良事件进行评估。
所有患者面部皮肤质地、痤疮疤痕和色素异常均有临床改善。平均临床改善率为50.2%。伤口在6至8天内完全愈合。所有患者均出现红斑，5例患者（3.9%）红斑持续超过3个月。9例患者（7%）出现炎症后色素沉着，1例患者（0.8%）色素沉着持续超过3个月。无患者出现色素减退。14例患者（11%）出现轻度至中度术后痤疮爆发。未观察到其他不良反应。
对于肤色较深的土耳其人群，Er:YAG激光表面重塑是治疗面部痤疮疤痕的一种安全有效的治疗方式。
