Are there any instruments that allow the physician to increase density in the recipient area?
No, there are no specific instruments that allow the physician to improve the yield when higher densities of grafts are placed into the recipient area. Studies have shown that densities above 30 grafts per square millimeter can result in a reduced follicle yield. There are two products we are currently using to help improve the yield of grafts, however. These two products are free radical scavengers and liposomal ATP. The accumulation of free radicals may be the cause of poor growth in some individuals who have grafts placed at a higher density. Free radical scavengers help reduce the concentration of free radicals and minimize oxidation by the free radicals during repercussion. Secondly, liposomal ATP provides nutrition or energy to the cells directly so that they do not need to manufacture ATP aerobically following removal of the grafts from the donor area. Minimizing production of ATP through glycolysis reduces the production of free radicals by the cells. Both products reduce free radicals so that higher density graft placement may result in a higher overall yield.
