The optimal timing of laser epilation with expanded forehead flaps in facial defect reconstruction remains undetermined. To compare the efficacy and safety of hair removal during or after flap expansion. This prospective exploratory study included 15 (11 women and 4 men, 16.47 ± 16.331 years of age) and 26 (19 women and 7 men, 10.69 ± 10.899 years of age) patients who underwent 755 nm long-pulsed alexandrite laser epilation during flap expansion and after surgery, respectively. Facial reconstruction was performed in these patients because of congenital melanin nevus, scar or port-wine stains. Evaluation included hair reduction rate, patient satisfaction, and adverse events. The median number of laser sessions for hair removal during flap expansion was significantly lower than that after surgery (2.00 vs. 3.00, < 0.01), and the hair reduction rate was also significantly higher during flap expansion (79.5% ± 21.93% vs. 68.3% ± 17.44%, < 0.05). No severe adverse events were reported. Laser hair removal is safe and efficient when performed both during flap expansion period and after surgery, but its efficacy was significantly higher, and fewer sessions were required when performed during tissue expansion.

在面部缺损重建中，使用扩张额瓣进行激光脱毛的最佳时机仍未确定。为了比较在皮瓣扩张过程中或之后脱毛的效果和安全性，本前瞻性探索性研究纳入了 15 名（11 名女性和 4 名男性，年龄 16.47±16.331 岁）和 26 名（19 名女性和 7 名男性，年龄 10.69±10.899 岁）患者，分别在皮瓣扩张过程中和手术后进行 755nm 长脉冲翠绿宝石激光脱毛。这些患者因先天性黑色素痣、瘢痕或葡萄酒色斑而行面部重建。评估包括毛发减少率、患者满意度和不良反应。皮瓣扩张过程中脱毛的激光治疗次数中位数明显低于手术后（2.00 次比 3.00 次， < 0.01），皮瓣扩张过程中的毛发减少率也明显更高（79.5% ± 21.93%比 68.3% ± 17.44%， < 0.05）。未报告严重不良事件。在皮瓣扩张期和手术后均可安全有效地进行激光脱毛，但在组织扩张时进行脱毛，效果显著提高，所需治疗次数更少。临床试验注册号：ChiCTR1900026090。
