Hairline Design and General Recipient Area :
The primary landmark that needs to be determined is the peak of the anterior hairline (AHL) (discern 1). In most instances, the location of the maximum anterior, mid-frontal portion of the hairline is between 7.5 and 9.5 cm above the glabella. The shape of the pinnacle, expected destiny hair loss, and donor potential are factors to consider in this innovative choice. One ought to vicinity the hairline in the sort of vicinity that it’ll look natural because the patient matures and continues to lose hair. If the temporal factor is anticipated to recede, a higher hairline ought to be taken into consideration due to the fact a low hairline with a misplaced temporal point shows a hairpiece. The temple factor has to be even or barely posterior to the frontal hairline. In conjunction with the aforementioned principles, a gently curving hairline has to be created, with care taken to always preserve a widespread frontal-temporal recession.
The most important factor to attaining a natural appearance to the hair transplant is the creation of a tremendous AHL (figure 11). This is achieved through the right location and design of the hairline as well as the usage of huge numbers of small grafts. The form of the frontal hairline should no longer be linear but ought to be damaged up with principal irregularities (triangles and gaps). The hairline must consist of a transition from the bald brow to a zone along with random placement of unmarried hair grafts from the softest hair to be had in donor; typically, those unmarried hairs are taken from the temporal donor fringe. Posterior to the unmarried hair grafts are FU containing 2 and three hairs with more potent bodily characteristics (figure 12). Recreating a woman hairline requires a design that consists of an extra rounded temporal infill and decrease hairline than the only generally created for guys (Figures 13 and 14). The lead writer prefers to create a tapered posterior forelock pattern of trailing design that renders the crownless round and mimics a herbal variant on the balding system (figure 15). A distribution of grafts recreating a natural whorl sample can be constructed at the posterior issue of the forelock.
Recipient Site Creation
There are various contraptions and methods with which to create a domain wherein a hair graft is placed. The fundamental standards that ought to underlie any technique consist of matching the size of the person recipient site with the length and width of the patient’s FU. As an instance, if short, unmarried hair grafts are located at the anterior hairline in a thin scalp, a smaller and shallower site is created that might be required to accommodate a bigger 3- to 4-hair FU positioned inside the thicker scalp. The maximum easy and value-powerful instrument for recipient web page creation is a hypodermic needle. Needle sizes starting from 23 to 18 gauges are usually used. A 19-gauge needle will produce a 1.1-mm slit so as to accommodate the size of the majority of FU of common density (figure sixteen). Any other famous device for site online creation is the sharp-point, 22.5-degree or the “mini” knife. Those devices, as well as microscopes designed for hair recuperation surgical procedure, are available through distinct vendors (Ellis devices, Madison, New Jersey; Tiemann-Bernsco & A to Z Surgical, Hauppauge, NY). Custom designed recipient blades can also be reduced to unique length from flat surgical prep blades the use of specialized slicing devices. In a few situations, a 08-mm to at least 15-mm hollow punch might be applied as well.
The angle of the recipient web page ought to mimic the angles of the no transplanted, existing hair increase. When hair is absent, a natural waft of hair is created. On most hair-lines, the angle of graft web page advent needs to be approximately 30 to 45 degrees anteriorly off the scalp. These effects within the illusion of extra insurance as well as a natural attitude. The hair at the left aspect of the hairline needs to be angled anteriorly and in the direction of the midline. As the hair progresses to the proper aspect, a switch must be made so that the hair on the opposite aspect is angled toward the midline. As cited above, a whorl is created at the midpoint of the crown vertex location through a spiraling of the angulation of recipient websites through a 360-degree rotation (figure15).
With site creation, several techniques and instruments are to be had for graft placement. The unique forceps used for planting are essentially diversifications of those utilized in the microvascular surgical procedure. The essential principles of this issue of the process consist of mild grasping of the grafts, maintenance of graft hydration, placement of grafts in the identical perspective of website creation, and additionally maintaining appropriate rotation of the herbal curvature of the hair graft. As with graft coaching, considerable skill is required to carry out this sensitive undertaking in a repetitive, traumatic, and greenway. Frequently, numerous “planters “working simultaneously to finish the process in an efficient way. A skilled assistant or physician can plant 200 to 300 grafts in step with an hour. Normally, the recipient websites are designed first and the grafts are located in the following step. But, some other approach known as the “stick-and-location” method incorporates each maneuver in a sequential manner. The “sticker” creates the blade of preference, and the “placer” inserts the graft right away before the next slit is evolved.
