摘要目的 探讨应用高密度显微外科毛发移植技术,综合移植多种微小型毛胚,治疗脂溢性秃发的临床效果.方法 切取患者头发生长浓密的枕、颞部头皮作为毛发移植供体,5倍专用手术显微镜下分离毛囊,制成多种微小移植毛胚,以三棱针、微型刀片和卵圆形打孔器在受区打孔,用显微外科移植镊,由前向后顺序将移植毛胚植入受区孔隙,术后定期随访.结果 32例脂溢性秃发,移植毛发的平均成活率为90%,Ⅰ期手术后患者满意度为81%,6例不满意患者行Ⅱ期手术后均达到了满意的治疗效果.随访12～24个月,毛发生长自然、密集,发质良好无脱落.结论 应用高密度显微毛发移植技术,综合移植多种微小型毛胚,具有手术时间短、植发密度高、覆盖效果好等优点,大部分患者Ⅰ期手术后即可获得满意的治疗效果.

abstractsObjective To investigate the therapeutic effect of dense-packing auto hair grafting technique on the restoration of seborrheic alopecia. Methods With local anesthesia, a scalp strip was harvested from the back of the head. Under operating microscope (Various graft was created from the scalp strip, including micro-grafts with 1-2 hairs, mini-grafts with 3-4 hairs and sliver graft with 5-6 hairs. In the alopecia recipient area, micro slots were made with a small triangle-edged needle for the micro-grafts,mini slits were made with mini blade for the mini-grafts and foramen ovale were made with a slot punch. The grafts were then implanted into these holes. Results 32 cases of seborrheice alopecia were treated with the above mentioned technique from March 2007 to July 2009. Postoperative following up for 12-24 month showed that the grafted hairs were growing well with average 90 % survival of the hair. 81 % of the patients obtained satisfactory results with only one stage operation. Six patients needed the second operation to improve the appearance. All of the patients were satisfied with the appearance. Conclusions The dense-packing hair grafting technique with various grafts not only saves time of operation, but also obtains dense grafted hair and well appearance. The results are satisfactory to most patients with only one stage operation.
