Comparisons With Follicular Unit Transplantation
Follicular unit extraction generally has a quicker patient recovery time and significantly lower post-operative discomfort than follicular unit transplantation (FUT). FUE provides an alternative to FUT when the scalp is too tight for a strip excision and enables a hair transplant surgeon to harvest finer hair from the nape of the neck to be used at the hairline or for eyebrows.
However, with FUE, the follicles are harvested from a much greater area of the donor zone compared to FUT, estimated to be eight times greater than that of traditional strip excision so requires patients to have hairs trimmed in a much larger donor area. As a result, the hair in the lower and upper parts of the donor area, where the grafts were taken from, may thin and this can make the donor scars visible. Follicles harvested from borderline areas of the donor region may not be truly “permanent,” so that over time, the transplanted hair may be lost.Maximum follicular unit graft yield is lower than with FUT and may result in greater follicular transection (damage). Due to the scarring and distortion of the donor scalp from FUE it makes subsequent sessions more difficult, and grafts are more fragile and subject to trauma during placing, since they often lack the protective dermis and fat of microscopically dissected grafts, ultimately which may result in poor growth. A problem of buried grafts can occur during the blunt phase of the three-step technique when the graft is pushed into fat and must be removed through a small incision. FUE can also be more expensive and take longer to perform than FUT, so grafts are usually out of the body longer, risking sub-optimal growth.

Famous quotes containing the words comparisons with, comparisons and/or unit:
“I don’t like comparisons with football. Baseball is an entirely different game. You can watch a tight, well-played football game, but it isn’t exciting if half the stadium is empty. The violence on the field must bounce off a lot of people. But you can go to a ball park on a quiet Tuesday afternoon with only a few thousand people in the place and thoroughly enjoy a one-sided game. Baseball has an aesthetic, intellectual appeal found in no other team sport.”
—Bowie Kuhn (b. 1926)
“The surest route to breeding jealousy is to compare. Since jealousy comes from feeling “less than” another, comparisons only fan the fires.”
—Dorothy Corkville Briggs (20th century)
“During the Suffragette revolt of 1913 I ... [urged] that what was needed was not the vote, but a constitutional amendment enacting that all representative bodies shall consist of women and men in equal numbers, whether elected or nominated or coopted or registered or picked up in the street like a coroner’s jury. In the case of elected bodies the only way of effecting this is by the Coupled Vote. The representative unit must not be a man or a woman but a man and a woman.”
—George Bernard Shaw (1856–1950)
