Another advantage of making small recipient wounds is the ability to create a "snug fit" for the follicular unit grafts. Unlike the punch grafts and some mini-grafting techniques; each of which removes a small bit of tissue in the recipient area; the trimmed follicular unit grafts used in FUT fit into small, needle-made incisions without any need for removing tissue. This preserves the elasticity of the scalp and holds the tiny grafts snugly in place. After surgery, the snug fit facilitates wound healing and helps to ensure that the grafts will get enough oxygen from the surrounding tissue in order to maximize their survival.
