Success in follicular unit extraction requires an understanding of forces, fluid dynamics, instrumentation, and individual patient variation. Sharp punches require a lower axial and tangential force to dissect follicular groups. The angle of hair emergence and the size of a punch influence the wound size and the depth of an incision. A procedure must be individualized based on surface follicular group characteristics; hair splay; and strength of attachment between the outer root sheath, inner root sheath, and adipose with regard to hair follicles.
毛囊单位提取的成功需要理解力量、流体动力学、器械使用以及个体患者差异。锋利的打孔器在解剖毛囊组时需要较低的轴向和切向力。毛发的生长角度和打孔器的尺寸会影响伤口大小和切口深度。手术必须根据表面毛囊组特征、毛发散开情况以及毛囊外根鞘、内根鞘和脂肪之间的附着强度进行个体化操作。
