Extraction of porous units (FUE): What is it?
Extraction of porous units (or FUE) is a way to grow hair follicles from the donor area (the back of the scalp and its sides as areas where hair does not fall throughout the patient’s life).
When culturing the hair in the extraction of porous units, the surgeon extracts each porous unit separately using a fine hole that varies in diameter from 0.7 mm to 1.1 mm. There are many types of holes and methods that can be used (manual holes, mechanical holes, etc.), all of which are capable of providing good culture results if carried out by experts. A significant difference in outcomes is determined by the surgeon’s ability and experience. In addition, there is a robot capable of assisting the surgeon in the extraction process.
Hair transplantation is similar to the method of extraction of porous units from the traditional technique known as “extinction” or “pore culture” (FUT) because the latter involves surgically removing part of the scalp from the donation area and then preparing the porous units outside the body by technicians Using a microscope. After suturing the scalp remains a longitudinal scar in the donation area. However, the extraction of porous units involves taking units one after the other. There is no cut or scrape in the scalp and there is no longitudinal scar; It is important to note that the extraction of porous units is not a scars procedure, rather than a longitudinal scar.
The porous units can be one, two, three, or four hairs grouped in each unit. This is critical to the success of hair culture; this is the natural way to grow hair. These porous units are very similar to the extraction of porous units and the culture of porous units.
To achieve the natural appearance in the culture, it depends on many factors – such as the front hairline pattern, good density, direction of culture, use of appropriate porous units in each location, etc. This can be achieved through either of these procedures.
As for the scars in the donation area, the method of extraction of porous units leaves many (hundreds or even thousands) of raster scars that are less than one millimeter in diameter. When the procedure is performed efficiently, it is not possible to see the scars even when shaving is short, but it shows the hair shaved completely in the form of white dots.
That is, the large point scars have ended with the use of new tools; if the diameter of the old holes is up to 0.5 cm or more; now the diameter of the holes is reduced by way of drawing the porous units to less than 1 mm. That is, the area of the cut is limited enough to the skin of the skin around the porous unit. Thus, the result of culture is similar to the extraction of porous units with the natural result of the culture of porous units in the form of displacement. In addition, every hole in the old style took about 15 to 20 hairs together to make its appearance as if it were stripped of doll hair, but that was now the past.
The extraction of porous units usually take longer than that of porous units. However, the time taken by the extraction surgeon varies according to the surgeon’s experience and speed in the culture, as well as from one patient to another. Thus, it may take up to two hours or more to extract 200 patches to correct a scar; up to a two-day operation to perform a larger session of 2,500 to 3,500 patches.
The donation area is recovering very quickly with this procedure; all the cut and guts are recovered within two or three days, especially with no surgical thread. The rate of recovery of the patient itself is similar to the culture of porous units: Hair begins to grow within 3 to 4 months after surgery at a monthly growth rate of 1 cm.
