The main objective of improving them more and more is to reduce the discomfort and pain perceived by the patient during the surgical procedure. There are basically two important phases in the FUE technique, where anaesthesia is essentially used to avoid causing pain to the patient:
The extraction of hair follicles from the donor area: this phase is carried out with the help of micro motors and micropunch tips. Together with these devices there are blades or scalpels (of surgical steel or sapphire) which are responsible for extraction in the donor region. The scalp is penetrated by blades, so administrating local anesthetics is a must. Besides using anesthesia, minimizing the scalpels’s rotation speed and using sharp blades can increase the patient’s ease during surgery.
The incision processing and the receiving area implantation phases: taking the DHI technique as example, the implant phase is preceded by the elaboration of the incisions where the hair follicles will be implanted in the receiving area. In the DHI technique, these two movements occur at the same time using a Choi implanter pen, which creates the incision and inserts the follicle into the scalp. The quality of the needles used will be proportional to that of the final result. Another case is that of sapphire blades, which are used to create the incisions before implanting the follicles, creating the conditions for a better postoperative process. This happens because the sapphire blades have a smoother surface, thus decreasing the risk of capillary complications.
