Surgical scarring is a common cosmetic problem that occurs in various surgical fields, including dermatology. Many trials have been conducted to determine how to prevent this distressing scar formation. A 1,550-nm fractional erbium-glass laser has been used to improve the appearance of surgical scars, but an appropriate treatment time has not been established.
To determine the appropriate time to apply 1,550-nm fractional erbium-glass laser treatment for thyroidectomy scars.
Korean patients with linear surgical suture lines after thyroidectomy (N = 65) were treated using a 1,550-nm fractional erbium-glass laser. Patients were divided into three groups according to postoperative treatment time. Laser treatment was started in 40, 15, and 10 patients 3 weeks, 3 months, and 6 months postoperatively, respectively. Each patient was treated three times at 1-month intervals using the same parameters (14 mJ, 100 spots/cm(2) , 2 passes).
Mean Vancouver Scar Scale scores were significantly lower after laser treatment (p < .01), with the greatest difference in the group that began treatment 3 weeks postoperatively. Global assessment also indicated better cosmetic outcomes in the 3-week postoperative treatment group.
Early postoperative 1,550-nm fractional erbium-glass laser treatment of thyroidectomy scars is more effective than later treatment.
手术瘢痕是一种常见的美容问题，发生在包括皮肤科在内的多个外科领域。已经进行了许多试验来确定如何预防这种令人痛苦的瘢痕形成。1550nm 铒玻璃激光已被用于改善手术瘢痕的外观，但尚未确定合适的治疗时间。
确定应用 1550nm 铒玻璃激光治疗甲状腺切除术瘢痕的合适时间。
对 65 例甲状腺手术后线性缝合线的韩国患者使用 1550nm 铒玻璃激光进行治疗。根据术后治疗时间将患者分为三组。分别于术后 3 周、3 个月和 6 个月开始激光治疗，每组 40、15 和 10 例。每个患者以相同的参数（14mJ、100 个光斑/cm²、2 次通过），间隔 1 个月治疗 3 次。
激光治疗后温哥华瘢痕量表评分显著降低（p<.01），术后 3 周开始治疗的组差异最大。总体评估也表明，术后 3 周治疗组的美容效果更好。
甲状腺切除术瘢痕的早期术后 1550nm 铒玻璃激光治疗比后期治疗更有效。
