Scarring alopecia on the head after the removal of a scalp lesion, such as a sebaceous nevus, can be a cosmetic concern. There are several reports on methods used for subgaleal dissection and incision of the galea when using simple sutures, but these methods have not been quantitatively analysed.
In this small case series, we compared 2 methods for primary wound closure following removal of scalp lesions, one involving only subgaleal dissection (group A) and the other involving both subgaleal dissection and additional galeal incisions (group B).
Fourteen patients were enrolled. The average excision width was 15.0 (range 8-22) mm in group A and 21.8 (range 18-32) mm in group B. The average width of alopecia was 5.6 (range 1-12) mm and 3.1 (range 3-4) mm, respectively.
In this case series, subgaleal dissection and an additional incision to the galea during simple scalp excisions not only expanded the limits of the closable defect width but also reduced the width of the resulting scarring alopecia.
头皮病变（如皮脂腺痣）切除后头部瘢痕性脱发可能会影响美观。有几篇关于使用简单缝线时帽状腱膜下剥离和切开帽状腱膜方法的报道，但这些方法尚未进行定量分析。
在这个小病例系列中，我们比较了头皮病变切除后一期伤口闭合的两种方法，一种仅涉及帽状腱膜下剥离（A组），另一种涉及帽状腱膜下剥离和额外的帽状腱膜切开（B组）。
共纳入14例患者。A组平均切除宽度为15.0（范围8 - 22）mm，B组为21.8（范围18 - 32）mm。平均脱发宽度分别为5.6（范围1 - 12）mm和3.1（范围3 - 4）mm。
在本病例系列中，简单头皮切除术中进行帽状腱膜下剥离和额外的帽状腱膜切开不仅扩大了可闭合缺损宽度的范围，还减小了由此产生的瘢痕性脱发的宽度。
