Follicular Unit Extraction (FUE) Hair Transplant
Follicular unit extraction or FUE is a hair transplant technique in which a small round punch is used to extract follicular units from a patient's bald resistant donor areas. These 1, 2, 3 and 4 hair follicular unit grafts are then transplanted into a patient's balding areas.
Given the time consuming and tedious nature of this procedure a physician is often limited to transplanting 500 to 600 follicular unit grafts in one day. The cost per graft of FUE is also typically twice the cost of the standard follicular unit hair transplant procedure in which a strip of donor tissue is removed from the back of the head and trimmed under magnification into individual follicular unit grafts.
How a FUE Hair Transplant is performed
During the Follicular Unit Extraction or FUE procedure individual follicular unit grafts are excised one at a time using a tiny one millimeter or less sized punch. Typically the patient's hair in the donor area where these grafts are being removed is cut short so that the physician is able to see the patient's scalp.
The follicular units are extracted using a multiple step process. First a small sharp punch scores the skin around a follicular unit. Then a small dull punch is used to go deeper into the soft tissue surrounding the follicular unit.
Since the direction and angle of the follicular unit beneath the skin can't be seen and can often differ from the direction of the hair on the surface, a sharp punch if used below the surface of the skin might transect or severe the underlying follicular unit. However, the dull punch tends to envelope the follicular unit, while separating it from the surrounding soft tissues. This process is typically referred to as "blunt dissection".
Once the underlying follicular unit is separated from the surrounding tissues it can then be extracted, often by a forceps gripping the hair above the surface.
The small hole left behind after the follicle is extracted then heals over the next few days. This tiny wound contracts as it heals making the resulting round scar smaller and less noticeable. The FUE patient typically ends up with hundreds of small round white scars, which are normally not detectable to the naked eye once the patient's hair grows out.
The aim of this article is to give you a general information about the surgical intervention in question. You need to make more research about possible complications and risks of this selected procedure in order to make an informed decision. Please note that complications occur more frequently with patients who are obese, smoke, and have a history or lung or other chronic underlying medical conditions.
Smokers are recognized to have a significantly higher risk of post operative wound healing problems with a subsequently higher potential of infection as well as operative and post operative bleeding. Patients should discontinue smoking for two weeks before and two weeks after surgery. Although it helps to stop smoking before and after surgery, this does not completely eliminate the increased risks resulting from long term smoking. Smoking also has a long term adverse effect on the skin and ageing process.
