Split-skin grafting is a routine reconstructive technique associated with large variation in practice. Grafts from the thigh, buttock, or abdomen take a long time to heal and may leave unpleasant, hypopigmented scars. Retrospective reports favor the scalp as a donor site in burn patients.
Evaluation of duration of healing, cosmetic outcome, and safety of split-skin grafting from the scalp in patients receiving dermatologic surgery.
One hundred sixty-six consecutive patients (85 men, 81 women) were treated for coverage of chronic leg ulcers or other large skin defects with a split-skin graft taken from the posterior scalp. Area and thickness of the graft, healing time, and adverse events were documented.
Mean healing time until complete reepithelization was 5.4+/-1.0 days for a single harvest (median 5 days). No major complications occurred. Spotted alopecia was a rare event. Almost all (96.5%) of the patients would undergo split-skin harvesting from the occipital scalp again if needed.
Advantages of the scalp as a donor site include rapidity of wound healing, low risk of complications, and excellent cosmetic results. The large number of hair follicles containing the epidermal stem cell pool can explain these advantages.
游离皮片移植是一种常规的重建技术，但在实践中存在很大差异。大腿、臀部或腹部的皮片需要很长时间才能愈合，并且可能留下令人不快的色素减退性瘢痕。回顾性报告倾向于将头皮作为烧伤患者的供皮区。
评估头皮游离皮片移植在接受皮肤科手术的患者中的愈合时间、美容效果和安全性。
166 例连续患者（85 名男性，81 名女性）接受了头皮后枕部游离皮片移植，用于覆盖慢性腿部溃疡或其他大面积皮肤缺损。记录皮片的面积和厚度、愈合时间和不良事件。
单次取皮的平均愈合时间（中位数为 5 天）直至完全上皮化需 5.4+/-1.0 天。无重大并发症发生。点状脱发是一种罕见的事件。如果需要，几乎所有（96.5%）患者都会再次接受枕部头皮的游离皮片移植。
头皮作为供皮区的优点包括伤口愈合迅速、并发症风险低和美容效果好。含有表皮干细胞池的大量毛囊可以解释这些优点。
