Eyebrows play an important role in protecting the eyes, and also transmit facial expression. Restoration of eyebrow loss after deep thermal burns is a challenging task because a scarred recipient area may affect the success rate of the hair transplantation outcome. Trials to improve this outcome via preparation of pretransplantation recipient area are mandatory.
Seventeen patients (20 eyebrows) with partial or total postburn eyebrow loss were recruited. Nanofat injection was done as a preparatory step before hair transplantation. Patients were followed up monthly for 6 months after follicular unit extraction. The outcome was assessed both objectively by phototrichoscopy and patient satisfaction, and by incidence of complications.
The mean eyebrow density of the recipient side was found to be 88.60 ± 29.96 hair follicle per cm, compared with 133.95 ± 38.38 on the control side. The mean eyebrow thickness of the recipient side was found to be 0.07 ± 0.01 mm, compared with 0.06 ± 0.01 on the control side, The overall satisfaction was 60% regarding the density, 80% regarding direction, and 65% regarding symmetry. However, when it comes to texture, 45% were satisfied.
Restoration of eyebrow loss after deep facial burn is a challenging procedure. Improving the recipient area before hair transplantation is recommended to achieve a satisfactory outcome. Waiting until maturation of the scarred tissue of the recipient area and preparation of it with nanofat can achieve a satisfactory outcome.
眉毛在保护眼睛方面起着重要作用，同时也传递面部表情。深度热烧伤后眉毛缺失的修复是一项具有挑战性的任务，因为瘢痕化的受区可能会影响毛发移植的成功率。通过术前准备受区来改善这一结果的试验是必不可少的。
招募了17例（20侧眉毛）部分或全部烧伤后眉毛缺失的患者。在毛发移植前，先进行纳米脂肪注射作为准备步骤。在提取毛囊单位后，对患者进行了6个月的每月随访。通过毛发镜检查和患者满意度客观评估结果，并统计并发症发生率。
发现受区一侧眉毛的平均密度为每平方厘米88.60±29.96个毛囊，而对照侧为133.95±38.38个。受区一侧眉毛的平均厚度为0.07±0.01毫米，对照侧为0.06±0.01毫米。总体满意度方面，密度为60%，方向为80%，对称性为65%。然而，在质地方面，只有45%的患者感到满意。
面部深度烧伤后眉毛缺失的修复是一个具有挑战性的过程。建议在毛发移植前改善受区，以获得满意的效果。等待受区瘢痕组织成熟并用纳米脂肪进行处理可以取得满意的效果。
