摘要
目的了解打孔同步植入毛囊单位法治疗烧伤后瘢痕性脱发的效果。方法2002年1月-2008年4月，2家笔者单位应用打孔同步植入毛囊单位技术，治疗166例患者共217个烧伤后瘢痕性脱发区域。根据移植需求量，于枕、颞部切取相应的含有完整毛发的头皮组织条，在显微镜或放大镜下分割成一定数量含1-3根毛发的毛囊单位。根据所需移植物大小，选用相应型号的注射针头于瘢痕脱发区内制备孔洞，在针头退出的同时，植入制备好的毛囊单位。对I期术后毛发密度不满意患者，半年后行Ⅱ期毛囊单位移植。I期术后即刻，随意选择10例患者共10个边界清晰的受区，肉眼观测毛囊单位移植密度及移植毛发数量；后期随访时，肉眼观测这10个受区的毛发成活数量，计算毛发成活率。另对患者术后满意度进行问卷调查。结果83例患者I期手术完成治疗，另83例患者Ⅱ期手术完成治疗。I期术后毛囊单位移植密度达15-25个／cm^2，移植毛发数量为40-70根／cm^2。所有患者术后随访8个月以上，移植毛发生长自然、良好。I期手术后选定的10个观察区（受区）毛发平均成活率为96.5％。仅行I期手术的患者术后非常满意者61例占73.5％，满意者22例占26.5％。Ⅱ期手术患者非常满意者76例占91.6％，满意者7例占8.4％。结论打孑L同步植入毛囊单位的移植技术安全，手术创伤小、出血少，术后伤口恢复快。应用该技术移植在瘢痕性受床上的毛发成活率高、生长良好。
Objective To study the effect of the technique of synchronously perforating and trans-planting hair follicular-units in the treatment of cicatricial alopecia after burn. Methods One hundred and sixty-six patients with 217 bald scar areas after burn were treated with above-mentioned technique from January 2002 to April 2008. Scalp strips, with conforming the necessity for grafting, were harvested from the occipital or temporal region. A series of follicular-units, each composing 1-3 hairs, were dissected from the strips under microscope or magnifying glass. Size-matching micro-slots were made in the scarred recipient area with 16-20 G needles to accept the grafts. The prepared follicular-unit was synchronously implanted into the bottom of the micro-slot as the needle being withdrawn. Patients who were not satisfactory with the density of hairs after I stage surgery underwent Ⅱ stage surgery a half year later. Ten recipient areas with clear boundary in 10 patients were optionally chosen to observe the density of follicular-units and hair amount with naked eyes after I stage surgery. Survived transplanted hairs in above-mentioned 10 areas were counted to calculate hair survival rate at follow-up. Patients＇ postoperative satisfaction ratings were surveyed with questionnaire. Results In one half of the patients, treatment was finished after I stage surgery, the other one half received 2 stages of surgery. The follicular-unit density reached 15-25 grafts/cm^2 with 40-70 hairs/cm^2 after I stage surgery. All patients were followed up for over 8 months. Grafted hairs grew well in a natural way. 96.5% mean hair survival rate was observed in the 10 recipient areas. From patients who received only I stage surgery, 61 patients （73.5%） were very satisfactory and 22 patients （26.5%） satisfactory with the results. From the other half of patients, 76 patients （91.6%） were very satisfactory and 7 patients （8.4%） satisfactory with the results. Conclusions The technique of perforating and transplanting follicul
