Follicular unit extraction (FUE) is becoming more popular in hair restoration. However, its potential for treating extensive scarring alopecia is unknown.
Patients with scarring alopecia larger than 100 cm2 were enrolled from 2015 to 2018. After assessing scar quality regarding vascularity, pliability, and thickness, dense-packing megasession (DPM)-FUE was performed on high-quality recipient sites. Patients were followed up at 1 week and 12 months postoperatively to evaluate complications, survival rates of grafts, and patient satisfactions. Cases of nonscarring alopecia were reviewed as controls.
Fifty-two scarring alopecia and 55 nonscarring alopecia patients were enrolled. The mean scar area was 120 cm2, and the procedure required an average of 8 operative hours, with no difference between groups (p > .05). Graft amount and postoperative complications were similar as well (p > .05). The survival rate in scarring alopecia was lower than that in the control but was still 85% (p < .05). Follow-up photographs showed effective scar camouflage after DPM-FUE. Most patients were very satisfied with the final results (p > .05).
DPM-FUE is a safe and effective treatment for extensive scarring alopecia.
毛囊单位提取（FUE）在毛发修复中越来越受欢迎。然而，其在治疗广泛瘢痕性脱发方面的潜力尚不清楚。
2015 年至 2018 年期间，我们招募了瘢痕性脱发面积大于 100 cm2 的患者。在评估血管化、柔韧性和厚度等瘢痕质量后，在高质量的受区进行密集型 megasession（DPM）-FUE。术后 1 周和 12 个月对患者进行随访，评估并发症、移植体存活率和患者满意度。回顾非瘢痕性脱发病例作为对照。
共纳入 52 例瘢痕性脱发和 55 例非瘢痕性脱发患者。平均瘢痕面积为 120 cm2，手术平均需要 8 个小时，两组间无差异（p >.05）。移植体数量和术后并发症也相似（p >.05）。瘢痕性脱发的存活率低于对照组，但仍为 85%（p <.05）。随访照片显示 DPM-FUE 后有效掩盖了瘢痕。大多数患者对最终结果非常满意（p >.05）。
DPM-FUE 是治疗广泛瘢痕性脱发的一种安全有效的方法。
