Today I will discuss the custom cut recipient blade sizes in hair transplant procedures that I use to create the recipient sites for my hair transplant grafts. I have a machine which allows me to cut custom sized blades. Typically my blades range in size from .5mm-1.1mm and I have blade sizes in every size in between in .05mm increments. This allows me to use the smallest possible blade for the patients natural follicular units. The hair type and caliber are defining characteristics that determine which size blade to use. Typically I try to find the smallest possible blade which still allows for easy placement. An extra .1mm opening may not seem like much, but when multiplied by 1500-3000, which is the number of recipient sites I create in a typical hair transplant procedure, an extra .1mm can add up to significantly more injury to the scalp and circulation, which in most cases is not necessary. I also custom cut my blades with a 45 degree angle at the end and I angle the deepest portion of the blade so that it is at the superior aspect of the incision. This means that the blade also causes less injury to the scalp circulation and positions the graft at a more acute angle which gives a better final result. Minimizing damage to the scalp and the vascular bed minimizes scar tissue in the scalp and thus minimizes the potential of “shock loss” (which I will address in another blog entry).
I hope this blog entry clarifies why the blade size is very important in Hair Transplant Procedures.
All the best,
