毛发单元移植行前额发际美人尖再造

Aesthetic anterior hairline (beauty-arch) reconstruction by using dense-packing follicular-unit hair grafting technique

目的探索应用一种高密式毛发单元移植技术,进行前额美人尖再造的新方法。方法切取近后发际区域处含有完整毛发毛囊的条形头皮组织,借助于手术放大镜,将之分割,制备成毛发单元(每单元含毛发1～3根),即显微毛发移植物。然后,在前额按个性化设计出弓尖形发际线,采用高密式移植技术,将毛发移植物移植至该区域内的预制洞穴中。结果本组58例患者,术后随访1年以上,其再造的前额美人尖毛发生长良好,美人尖形态、走向自然,其发际内无可见的瘢痕形成。毛发的成活率平均达98%。结论高密式毛发单元移植技术再造的前额美人尖,其手术方法简便,创伤小,外形自然美观,是目前美容性前额美人尖再造的理想方法。

Objective To search a new method for aesthetic anterior hairline （beauty- arch） reconstruction, Methods Under the local anesthesia, a scalp strip containing abundant hair follicle was harvested from the back of the head, closing to the posterior hairline. A series of follicular - unit micrografts with 1 3 hairs were then divided under surgical magnifier. Usually, 200-800 micrografts were needed for the anterior hairline reconstruction. After the micro- holes were prepared using an injective needle in the recipient site, the grafts were implanted by a dense - packing grafting technique into the holes, parallel to the original hair directions. Results Fifth - eight patients with a flatted anterior hairline were treated by the above - mentioned technique from Apr. 1998 to Aug. 2005, All of the patients were satisfied with the results. The survival rate of the grafted hairs were 98 %. The appearance of the reconstructed hairline was quite natural without visible scar. Conclusion The above - mentioned technique could be a simple, safe and effective method for anterior hairline reconstruction.
