The lateral slit technique, used in combination with custom-sized openings, creates the opportunity for larger graft numbers, higher density, and more natural results especially with one day Fue hair Transplant procedure.
Recipient sites refer to the precise location where the prepared follicular units are placed. Recipient sites are made by making small incisions to exactly fit the size of the patient’s follicular units. The surgeon prefers to create lateral slits (also called coronal or horizontal slits) vs perpendicular slits as lateral slits have the advantage giving the maximum degree of control of the direction that the hairs will grow and also the precise angle that they grow out of the skin.
The lateral slit technique allows to us to provide maximal density and coverage, as the hairs tend to fan out over the surface of the scalp in a layering effect giving the illusion of higher density, and ultimately a more natural appearance. The perpendicular technique (also referred as the sagittal technique) can result the hairs to stick up giving an unnatural appearance.
The angle that the hair exits the scalp is absolutely critical in achieving a natural appearing result. In the frontal hairline and the central crown areas, the hairs exit the scalp in a very acute angle. In the mid-scalp region, the hairs exit the scalp in a forward angle, but not as acute. Utilizing the lateral slit technique, the surgeon is able to specifically create an opening for the follicular units at the exact angle for the particular area that is being transplanted.
The surgeon is able to make more openings in a given space maximizing graft density and ultimately a more natural result. Furthermore, recovery time is also developed because the grafts will fit perfectly into the recipient sites maximizing oxygenation, promoting faster healing, and increasing graft survival.
