单位毛囊移植在毛发缺损修复中的应用

Application of Follicular Unit transplantation in repairing hair loss

目的：探讨使用单位毛囊移植修复毛发缺损的方法及效果。方法：取枕部的优势供区毛发按需要将其分割为含有1～4根毛发的毛囊单位，存于4℃的冰盐水中待用；受区使用局部肿胀麻醉加神经阻滞麻醉，然后用18～21号gauge注射器针头按不同受区毛发分布的角度及方向进行刺孔，在显微镊子配合下以插秧的方法将备好的毛囊单位植入受区，弹力绷带加压包扎固定。结果：2005～2010年，笔者使用单位毛囊移植修复各种毛发缺损患者11例，术后随访6个月-1年，毛发成活良好，修复后的毛发外观自然，供区瘢痕不明显。结论：单位毛囊移植在毛发缺损修复后毛发的外观接近自然毛发分布特征，供区瘢痕不明显，是修复毛发缺损的一种好方法。

Objective Our objective is to explore the methods and effects of application of Follicular Unit transplantation in repairing hair loss. Methods During the operation, we cut the dominant donor site of occipital scalp and converted into follicular unit grafts containing 1 to 4 hairs with tumescence anesthetic. And then, all the follicular units grafts prepared for transplantation were stored into 4℃ chilled saline solution. After tumescence anesthetic or field nerve block, we began to transplant using 18 to 21 gauge needles and micro-forceps by stick-and-place technique in different angles and orientations. Last, we protect the recipient site with pressure bandage. Results From 2005 to 2010, 11 cases with different kinds of hair loss were repaired by follicular unit transplantation. The hair survival is good in 11 cases which were followed up 6 months to 1 year after operation. The appearance of recipient site is nearly the same to natural and donor site scar is not notable. Conclusion The hair appearance after operation is close to the natural. Follicular unit transplantation is a superior method contrast to traditional methods in hair loss repairing.
