Abstract：
BACKGROUND: Congenital melanocytic nevi (CMN), benign pigmented birthmarks caused by the mutation of melanocytic cells during embryofetal development, can cause aesthetic problem when it is located on the face. Surgical managements of facial CMN are required by both pediatric patients and their parents. Surgical management, including excision or staged excision, skin grafting, dermabrasion, tissue expansion or multiple re-expansion combined with flaps transplantation, have been reported previously. However, a systematical report about facial CMN management is still scarce.
OBJECTIVE: Herein, we have reviewed our serious of patients with facial CMN, noting their size, location, and histological examination, summarizing the surgical relation behind reconstructive and cosmetic treatment, and proposing a newly classification for facial CMN among pediatric patients, hoping to share a useful surgical algorithm for these lesions on this specific part.
CONCLUSIONS: Proper surgical strategy should be made based on the size and location of the nevi and the adjacent relationship between the location and relaxed skin tension lines and aesthetic units. Postoperative ant-scar treatment improves aesthetic outcomes. With our experience and surgical algorithm about facial CMN surgery, a favorable outcome can be achieved.

摘要：
背景：先天性黑素细胞痣（CMN），胚胎发育过程中黑素细胞突变引起的良性色素性胎记，当它位于脸上时，会导致美学问题。儿科患者及其父母都需要对面部CMN进行手术管理。手术管理，包括切除或分期切除，植皮,磨皮术,组织扩张或多次再扩张结合皮瓣移植，以前有报道。然而,关于面部CMN管理的系统报告仍然很少。
目的：在此，我们已经回顾了我们严重的面部CMN患者，注意到它们的大小，location,和组织学检查，总结重建和美容治疗背后的手术关系，并提出了儿科患者面部CMN的新分类，希望在这一特定部位分享这些病变的有用手术算法。
结论：应根据痣的大小和位置以及位置与松弛的皮肤张力线和美学单位之间的相邻关系制定适当的手术策略。术后抗瘢痕治疗改善美学效果。根据我们关于面部CMN手术的经验和手术算法，可以取得有利的结果。
