其实我看关键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.而我了解了国内几家医院包括北京八大处的那家,用的都还是minimicrografting.为什么不采用fut主要原因可能还是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.怎么办是好? 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." ![]() the nhi team performing stereo-microscopic dissection. in mini-micrografting, neither preserving follicular units nor even keeping hair follicles intact are felt to be that important. rather, the speed and economics of the procedure are the deciding factors. mini-micrografters use a multi-bladed knife to quickly generate thin strips of tissue and then use direct visualization (rather than microscopic control) to cut the tissue. the resulting grafts are generally larger than follicular units and since the excess skin is not trimmed away the donor sites are also larger. ![]() perfectly intact 1-, 2-, 3-, and 4-hair follicular units removed from the donor strip using a dissecting stereo-microscope. a major advantage of follicular unit transplantation, (besides preserving follicular units and maximizing growth) is the ability to use small recipient sites. grafts comprised of individual follicular units are small because follicular units are themselves small, but also because the surrounding non-hair bearing tissue is removed under the microscope and doesn´t need to be transplanted. follicular unit grafts can be inserted into tiny needle-sized sites in the recipient area, which heal in just a few days without leaving any marks. when performed by a skilled surgical team, follicular unit transplantation can provide totally natural looking hair transplants that make the full use of the patient´s donor supply to give the best possible cosmetic results in the fewest possible sessions. if its so much better why is it not performed by all doctors? the simple answer is cost. it takes longer to cut the follicles into follicular units and requires that the staff are better trained. also many doctors are reluctant to upgrade their facilities while mini micro-grafting gives reasonable results. if you are shopping by price and are looking for the lowest price per graft, you will most likely end up with micrografts and not follicular units. 这两张照片就是植发效果失败的案例. ![]()
