The FUE Hair Transplant
For some years the technique of direct removal of follicular units from donor areas has been experimented (a technique known as FUE Hair Transplant and conceived by Woods in Campbell) and the immediate replanting of the recipient areas. The results are very satisfactory, giving superior aesthetics and very low morbidity. The extraction of follicular units today represents a decisive and indispensable approach within the scope of the possibilities of hair surgery. It plays a decisive role both as an initial choice directed at the problem of alopecia, and as a complementary action to be taken after classical surgery (strip, flap, etc.). In recent times, the international scientific literature has been enriching itself with contents about this innovative technique, which, however, few practice until now, but which is starting to have growth and diffusion. It is obvious that you need to know some essential aspects to undertake this technique. In fact, in this perspective it is first necessary to select the candidate patients for this type of approach, remembering that the indications for FUE Hair Transplantation are very broad, being able to resort to this method when you want to avoid post-surgical scars, when the patient's orientation is for a less invasive intervention, in patients where the donor area is not very thick not to allow the surgical strip, in patients with limited thinning, to thicken short areas such as eyelashes, eyebrows, for small areas of alopecia secondary to dermatological diseases, to resolve the unsightly scars sometimes deriving from the traditional surgical strip, in case of scars resulting from trauma or neurosurgical procedures.
The contraindications to FUE Hair Transplantation
The contraindications to FUE Hair Transplantationare essentially represented by the operators' inexperience in using the method, when the adequate armamentarium of equipment is not available, in case of lack of patient consent, in case of expectations that do not correspond to the real possibilities that the technique can offer.
From a more strictly technical point of view, the technique consists of first preparing the donor area, which is shaved until 1.5mm short hair is obtained, with subsequent infiltration of local anesthetics to induce subcutaneous analgesia. For a correct and efficient execution of the method it is essential to have: a specific binocular microscope with the possibility of magnification from 6 to 10 times the field, in order to obtain a good visualization; of specific manual or automatic punches, of different shapes and sizes (from 6 to 10 mm in diameter) to extract the follicular units.
It is essential to establish the correct positioning of the punch when penetrating subcutaneously, so that a certain angulation of the insertion between the instrument and the follicular unit results, thus avoiding the transdissection that compromises the quality and vitality of the follicular unit itself.
The extraction maneuver using the punch must be delicate but decisive.
