目的 探讨应用毛发移植技术重塑额颞部发际线的手术技巧.方法 2010年10月至2016年10月,北京大学第三医院成形外科为120例女性美容就医者重塑发际线.在发际线植入毛发时,不规则排列毛发,移植密度40~55毛囊单位(FU)/cm2,植入毛发与额部皮肤呈30°~45°,颞部呈15°~20°,挑选最细毛发放在发际线边缘.结果 120例美容就医者随访10~24个月,其中非常满意95例,满意25例.其中9例感觉额部中央毛发密度较低,进行了2次加密手术;3例感觉发际线边缘毛发较整齐,进行再次植发手术调整整齐的发际线;6例感觉发际线边缘毛发较粗硬,未做处理;1例感觉发际线降低程度不够,进行了再次植发降低发际线,6例出现移植毛发不同程度卷曲,经过1~2年基本恢复正常.发际线移植毛发密度(44.7±8.1) FU/cm2.9例美容就医者感觉额部中央区域毛发稀疏密度(36.9±3.1) FU/cm2.发际线边缘毛发直径(57.5±13.5)μm,6例感觉发际线边缘粗硬的美容就医者毛发直径(70.2±5.1) μm.额部发际线移植毛发与皮肤角度(40.2±8.5)°,颞部毛发与皮肤角度(18.2±4.7)°.结论 女性额颞部发际线植发过程中,遵循毛发的不规则排列、适当的毛发密度角度和粗细毛发的合理分布能再造出自然的发际线.
Objective To explore the operative method and skill for female frontotemporal hairline reconstruction.Methods From October 2010 to October 2016,120 female patients were performed with the hairline reconstruction.The follicular units were arranged irregularly,40-55 FUs/ cm2,with 30°-45° angle from the forehead skin and 15°-20° angle from the temporal skin.The finest hairs were selected and arranged in hairline margin.Results All the patients were followed up for 10-24 months.95 patients were very satisfied,25 patients were satisfied,and no patients were unsatisfied.9 patients complained low density in the middle of the hairline and they had another surgery to improve the density.3 patients's hairline was regular,and another graft was done to correct the unnatural appearance.6 patients's hairs of the hairline margin were thick,hut no further treatment was done.1 patient underwent hair transplantation again,because of the still high hairline.6 patients's transplanted hairs appeared curly,and the curly degree was decreased after 1-2 years.The density of the transplanted hair was (44.7±8.1) FU/cm2.The density of 9 cases who complained low density in the middle of the hairline,was (36.9 ± 3.1) FU/cm2.The hair diameter of the hairline edge was (57.5±13.5) μm.The hair diameter of 6 cases who felt the hair thick was (70.2±5.1) μm.The angle of hair and the frontal skin was (40.2±8.5)°,The angle of hair and the temporal skin was (18.2± 4.7)°.Conclusions In female frontotemporal hairline reconstruction,nature hairline is created by irregular arrangement of hairs,proper density and angle and exact arrangement of different diameter hairs.
