HAIR STEM CELL TRANSPLANTATION
WHEN THE DONOR AREA IS INSUFFICIENT OR FULLY UTILISED
Some patients have already had one, sometimes even two hair grafts, perhaps with the FUE technique or even with FUT STRIP. Or they want to restore with auto-transplantation a large bald spot.
When alopecia is very high, those who suggest hair transplantation procedures attempt to please the patient as much as possible. Every time, when these interventions are carried out abroad at low cost, in order to avoid to return the patient a second time, a mega operation is promised to him, after having extracted, even 5000 follicular units.
The risks of a major hair transplant : necrosis and depletion of the donor
A massive hair transplant has two major disadvantages. The first concerns the risk of necrosis of the scalp, which is traumatized by an exorbitant number of lesions caused by the implantation of so many transplants. The second is that the removal of as many follicular units from the donor area often results in it being completely emptied. Maybe even to the limit of the follicular capital he’s got.
Sometimes wanting to remove a lot of follicular units the surgeon or the nurse also access nonadhydroxysterone in sensitive areas. The patient is then transplanted sometimes also follicle units which are rather intended to fall, because similar to those already fallen. With large withdrawals of this kind, to avoid necrosis, it is nea certain in the majority of cases that you get an emptying of the donor zone, and this in greater proportions. This is even more happening when the area is meager.
Consequences of transplanting too many follicular units with FUE technique
The impact of that is unfortunate and disappointing. Even with 5000 follicular units, you won’t get a satisfying restoration if we are Norwood scale 5 or above. The patient often will get a frontal line quite backward, so, at least in front of the mirror, he will have an idea of density. Then, by going back to the head, the follicular units will be transplanted less densely, hoping to reach the maximum possible surface area.
In most cases, however, the vertex will remain exposed or, at best, quite sparse. Aving depleted the donor zone of almost everything it could give in terms of donor capital, the patient finds himself no longer having the opportunity to repeat the surgery having almost exhausted the units to be transplanted and finding himself with a transplant with an incomplete and therefore unsatisfactory appearance, compared to the idealistic idea that every patient has of the transplant : you dream of becoming again like when you had a thick hair.
It’s disappointing to find yourself with a half-bald head or at best half-naked. When the desire drives the patient to consult again to finally arrive at that result that despite the illusions he could not achieve, unfortunately, his donor zone will not be able to have any more grafts extracted because completely exploited.
An exploited donor zone is aesthetically unpresentable
After many withdrawals, the patient will get a donor zone with many small shortages. This. will make it impossible to wear short hair because the shortages will be unpleasantly in evidence. This is about the FUE hair tecnhique.
Donor area subject to FUT strip technique
Things do not improve if the patient for restoring his hair has chosen FUT technique (Follicular Unit Transplantation) also known as STRIP. This type of surgical procedure cuts the donor area a whole part of the scalp. It is divided into several sections of tissue containing follicle units. With a good surgeon, large amounts of follicular units are obtained from such a sample, even in excess of 4500.
In the case of a big intervention of FUE (Follicular Unit Extraction), the price paid by the patient for this surgery is quite high. It is instead primarily the operation itself which is much more challenging than a simple extraction of follicular units, This surgical operation involves a suture at the origin of a long scar and a complex post-operative course, sometimes painful and unpleasant to see.
The stitches shall be removed after a week. the cicatrization may be originating annoying itches. The follicular units are cut into tiny squares of tissue. They are inserted into holes of round shape, so there is the possible formation of orange peel surfaces.
As for FUE even when many follicular units are extracted, the result could be incomplete. Some areas at the best will be only slightly repopulated. The long scar on the back of the head will impeach the wearing of short-cut hair.
HST : Hair Transplant for extensive baldness and depleted donor areas
There is a technique that provides the patient with an optimum solution when he is in one of the following situations: a large baldness of at least 5 in Norwood scale. In this case, at least 30/40 percent follicular units are missing. Either the patient has never had surgery, or he may have had one or more procedures with traditional techniques without solving his problem. If the situation is that a large area of baldness has to be treated, and the donor is still insufficient with the amount of follicular units still available in the donor area, HST is the solution.
The technique that is the solution to the problem is called HST English acronym that means Hair Stemcell Transplantation and in longer form is called PL FUT ie Partial Longitudinal Follicular Unit Transplantation. This technique consists in the only partial collection, through the use of punches from 0.5/ 0.6 mm , very small Grafts, preticamente free of skin tissue.
Hair Stem Cells create Hair Multiplication by cloning
If the hair stem cells contained in a follicular unit, are divided into two portions, one partially removed and the other remaining in situ in the donor zone, both are cloning the follicular unit in two places. Each follicular unit processed in this way generates two of identical type and nature. This is called hair multiplication, which is the multiplication of follicular units.
The hair multiplication replaces the insufficient Hair from donor areas. This can happen with successive phases, spaced at least of 9 months between two successive procedures.
The previous cases can find solutions for the patients and they will have multiple benefits, a simple post-operative period, without itching, without bandages and without risk of necrosis. Without fibrous hardening of the scalp. In addition, at each operation its donor zone will regenerate as before, with a situation incomparable to the cases previously examined.
