Hypopigmented scars are challenging to treat, and the focus for successful treatment is to cause pigment cells to produce more melanin. In this study, we evaluated the repigmentation effects of 0.4 mm motorized-micropunch grafting with skin-seeding for hypopigmented scars. Twenty-one patients with hypopigmented scars on the face and neck that had been resistant to conventional treatment and who had finally undergone micropunch grafting with a skin-seeding technique (SST) were retrospectively reviewed. Repigmentation outcomes were evaluated with global assessment by a physician using a 4-point repigmentation scale. Adverse events were noted. The subjects were followed for a 2-year follow-up period post grafting. All 21 subjects exhibited excellent to complete repigmentation of more than 75% of the hypopigmented scars. More than 90% repigmentation was observed in 17 patients. The mean duration for repigmentation that the subjects were satisfied with was 5.5 months. No adverse effects or recurrence instances were observed. Motorized micropunch grafting is an effective and promising alternative treatment for repigmentation of hypopigmented scars.
色素减退性瘢痕的治疗具有挑战性，成功治疗的重点是促使色素细胞产生更多的黑色素。在这项研究中，我们评估了 0.4mm 动力微钻孔移植联合皮肤播种治疗色素减退性瘢痕的复色效果。回顾性分析了 21 例面部和颈部色素减退性瘢痕患者，这些患者对常规治疗有耐药性，最终接受了微钻孔移植联合皮肤播种技术（SST）治疗。通过医生使用 4 分复色量表对整体评估来评估复色效果。注意不良事件。在移植后 2 年的随访期间对受试者进行随访。所有 21 例患者的色素减退性瘢痕均有超过 75%的极好至完全复色。17 例患者的复色率超过 90%。受试者对复色满意的平均时间为 5.5 个月。未观察到不良反应或复发。动力微钻孔移植是治疗色素减退性瘢痕复色的一种有效且有前景的替代治疗方法。
