Follicular unit Extraction (FUE) and Follicular Unit Transplantation (FUT)are the main techniques used to harvest follicles from the donor region. FUE involves extracting grafts one by one from the donor area using special instruments. FUT involves dissecting the grafts from a strip of the scalp obtained from the back or the sides of the head.
History of Hair Transplantation
First hair replacement surgery was performed by a Japanese dermatologist Dr. Okuda in 1940. Unfortunately, Dr. Okuda died in 2nd World War and the scientific publications could be discovered after so many years. In 1970, an American dermatologist Dr. Orentreich published the rules of hair implantation and in 1998 an American dermatologist Dr. Bernstein submitted his scientific article relating possibility of natural looking scalp hairs with transplanting natural occurring groups of follicular units. FUT was a major advance over the mini-micro grafting technique that preceded it. In mini-micro grafting, the graft sizes were arbitrarily determined by the doctor who cut the donor tissue into different size pieces (this technique was also called grafts “cut to size.”). Mini-grafts, which might contain up to 12 hairs, were bulky and could produce a tufted appearance. They also could result in a dimpling of the underlying skin. Micro-grafts, on the other hand, were frequently damaged during the removal process or were too fragile to survive. Since 2002, FUE method where follicles are extracted one by one from the donor area has been in use. American board certified (ABHRS) surgeonDr. Civashas been deeply researching and studying about hair transplantation while also attending hair-loss and treatment conferences overseas. The content of this website will provide you information about the causes of hair loss in men and women, their classifications, appropriate treatments for their problems and also the right way can only be determined by specialist.
FUE and FUT Techniques
FUTa thin strip of hair is taken from the back and/or sides of the scalp, and the area is stitched back. The hair from above the incision covers scar so that it is not visible. The donor strip is placed under a series of special dissecting microscopes where the individual follicular units, of one to four hairs, are carefully dissected into tiny grafts. These grafts are stored in a special holding solution and refrigerated while awaiting placement in the bald or thinning scalp (the recipient area). Meticulous stereo-microscopic dissection is a crucial part of the procedure, to achieve maximum yield from the donor strip.
With lateral slit technique, recipient sites (tiny incisions) are then made in the bald scalp where the grafts are to be inserted. This technique ensures fuller denser and natural appearance. You do not need to shave the existing hair at the recipient area since the doctor can work within the existing hair.
Once the recipient sites are made, the grafts are carefully inserted into the scalp. The 1FUs are placed at the hairline; the 2′s immediately behind them and the larger 3 and 4FUs are placed in the central, forelock area. The recipient site sizes are matched to the different size follicular unit grafts, so that a snug fit is created. This facilitates healing, enhances growth of the follicles and permits a very easy post-op care.
InFUEa relatively large area in the back and sides of the scalp is shaved to approximately 1-mm in length. Instead of removing a single strip, as in FUT, a tiny circular incision is made around each follicular unit group. The grafts are then extracted, one-by-one, directly from the scalp. The tiny wounds are small enough to be left open and heal on their own, which takes about a week. The remainder of the procedure is similar to Follicular Unit Transplantation.
In both procedures, the hair transplant is visible only for a week. Patients can resume normal daily activities the second day following the procedure, new hair growth starts to appear in 2 to 3 months and is generally completed in 10 to 12 months.
