摘　　要：目的探讨高密度毛发移植术在瘢痕性脱发修复中的疗效及其特点。方法首先根据脱发区的面积及毛发的移植密度计算出移植毛囊的单位数；然后以患者的枕后部为供区，切取优势的头皮条，采用显微分割的方法将其制成保留正常解剖结构的毛囊单位后植入脱发区。自2005年1月至2010年12月，对76例瘢痕性脱发患者行高密度毛发移植术。结果术后随访76例患者6～18个月，其中脱发区被完全覆盖者36例，为优；基本覆盖者24例，为良；毛发的密度较低，仍有部分脱发区外露者13例，为可；头皮瘢痕明显外露者3例，为差。移植后的毛发外形自然，患者满意。有2例患者发生表皮样囊肿，经局部处理后愈合。结论高密度毛发移植治疗瘢痕性脱发具有创伤小、恢复快、移植密度和成活率高、毛发生长形态自然等特点，术后效果满意，值得推广使用。Objective To investigate the effect of high-density hair transplantation on the treatment of cicatrieial alopecia and its features. Methods The units of transplanted hair follicle were counted according to the area of cieatricial alopeeia and required hair density. Scalp strip from the occipital region （ donor site） was harvested, and then it was transplanted into the recipient sites （cicatricial alopecia ） after the taken scalp was made into hair follicle units with anatomic structure reservation by microscopic dissection. From January 2005 to December 2010, totally 76 patients with cieatrieial alopecia underwent the operation metioned above. Re- sults After 6 - 18 months follow-up in 76 patients, excellent results （ complete cover） were achieved in 36 pa- tients, good （basic cover） in 24 patients, so-so （lower-density transplanted hair or part uncovered cicatricial alopeeia ） in 16 patients. All cases were satisfied with the results except for 2 patients with epidermoid cysts which were healed with local treatments. Conclusion The high-density hair transplantation is a good method for treating cieatrieial alopeeia with such advantages as slight invasion, quick recovery, high transplanting den- sity, high survival rate and satisfactory postoperative results. It is worth extending in clinic.
