Hair loss due to scarring as a consequence of surgical procedures and trauma can impact young patients socially and emotionally. Recently follicular unit extraction (FUE) hair transplantation has been applied to scar treatment.
This report included four patients with scarring alopecia. All patients were female with a mean age of 12.5 years. Previous operations that caused scarring were sebaceous nevus excision with direct closure (n = 2), an extensive burn scar treated using an expander (n = 1) and cauterization for a congenital pigmented nevus (n = 1). The average size of the affected area was 10.5 cm . The FUE transplantation procedure was performed under local anesthesia. The number of grafts was set at approximately 25-30 grafts/ cm of scar. An electronic punch with a diameter of 0.8 mm was used for graft harvesting, and a 0.6-mm electronic punch was used to make cylindrical holes on recipient site. The donor sites were shaved followed by graft harvesting in two cases. For the other two cases, harvesting was done without shaving.
The number of transplanted grafts was 60 to 600 (mean 288), and surgical time was 38 to 220 minutes (mean 108). The average dose of lidocaine was 1.4 mg/kg. The average survival rate of the grafts was 85%.
Our experience in these cases suggests that this technique may be a viable option for the treatment of certain causes of scarring alopecia in the pediatric age group.
由于手术和创伤导致的瘢痕性脱发会对年轻患者的社交和情感产生影响。最近，毛囊单位提取（FUE）毛发移植已应用于瘢痕治疗。
本报告纳入了 4 例瘢痕性脱发患者。所有患者均为女性，平均年龄为 12.5 岁。导致瘢痕的既往手术包括：皮脂腺痣切除后直接缝合（n=2）、扩张器治疗大面积烧伤瘢痕（n=1）和先天性色素痣电灼（n=1）。受累区域平均大小为 10.5cm 。FUE 移植手术在局部麻醉下进行。每个移植区移植的毛囊数量约为 25-30 个/cm 。使用直径为 0.8mm 的电子打孔器进行毛囊提取，用直径为 0.6mm 的电子打孔器在受区制作圆柱状孔。2 例患者供区剃毛后进行毛囊提取，另外 2 例患者未剃毛直接提取。
移植的毛囊数量为 60 至 600 个（平均 288 个），手术时间为 38 至 220 分钟（平均 108 分钟）。平均利多卡因用量为 1.4mg/kg。移植毛囊的平均成活率为 85%。
我们的经验表明，对于儿童瘢痕性脱发的某些病因，该技术可能是一种可行的选择。
