其实我看我们应该关心的首要问题还是头发移植后是否自然.尤其是多于三级以上的脱发患者来说更是这样,下面的文章说的就是是采用fut还是minimicro-grafting技术的区别,fut要使用显微镜分离发囊,而minimicro-grafting是直接在肉眼下操作.所以要使移植后的头发自然就要采用fut.而我问了国内的几家医院包括北京八大处的那家,用的都还是minimicrografting.为什么国内医院目前不采用fut主要原因可能还是fut所化的精力和成本太高,但如果植的发效果不自然,还不如没有头发时候好.怎英语好的朋友可以看看下面这篇关于fut与minimicro_graft植发技术进行比较的文章。有兴趣的朋友一起讨论啊. how is follicular unit transplantation different from mini-micrografting?
in follicular unit transplantation the graft sizes are determined by nature, in mini-micrografting the graft sizes are arbitrarily determined by the surgical technicians who cuts the donor tissue into the size pieces that the doctor has requested. another name for this technique is mini-micrografts "cut to size."
