MANUAL FUE TECHNIQUE
With manual FUE technique, the grafts are extracted by means of a punch attached to a handle. With circular movements of the hand, the punch is inserted into the scalp, after which the grafts are extracted with the help of tweezers. Manual insertion of the punch, and extraction using tweezers, are the two critical moments as regards the vitality of the grafts, since the considerable mechanical trauma involved in these operations may damage the donor material.
This technique has two shortcomings, which influence the effectiveness of the procedure (the percentage of grafts that take root and the number of grafts transplanted at a single stage):
- Risk of damaging the donor material during extraction (it decreases the percentage of surviving grafts – the loss may attain from 20% to 30%)
- Insufficient speed of the procedure (it limits the number of grafts – in a period of 4 to 6 hours, only 1200 to 1500 grafts may be extracted)
- MOTORIZED FUE TECHNIQUE
