Hair transplantation History
Hair transplantation was first introduced by Okuda in 1939.
And then, Hajime Tamura reported that one to two follicles had grown after transplanted to the atrichia woman.
In the early 1950, Orentreich reported that the most important principle in hair transplantation, < Donor Dominance-the idea that grafts continue to show the characteristics of the donor site after they have been transplanted to other site >
After that, punch-graft technique was conducted but it had problems that there were many scars remaining on the donor area and uneven skin of recipient area.
In the 1990s, because smaller grafts can be easily survive and looked natural after transplantation, the micrograft technique- using a graft contains one to three follicles, and minigraft technique- using a graft contains four to six follicles, are introduced.
At ISHRS 1996 in Nashiville, Dr.Rassman emphasized the importance of follicular unit, and Dr.Seager did the advantages of using a microscope. This established the newest concept of transplant technique with a microscope.
Transplanting on Scars
The survival rate of transplanted hairs varies according to the scars´ depth and degrees.
It is desirable to consult with a plastic surgeon because it can be more efficient to take scar remove surgery at the same time. Transplanting on scars are usually conducted the situations below.
1. Surgical scars or burning scars on the scalp
2. Scars on between eyebrows
3. The surgical scars left by face-life procedure
4. Scars on the spot of mustache or beard
5. Scars around lips after cleft lip surgery
Eyebrows are protecting the eyes from rain or snow but also critical to define the way we look.
The eyebrows, whether one has innate thin ones or scars on them, can be restored by hair transplant surgery. Usually 200-300 follicular unit grafts are transplanted on the eyebrow site and it is necessary to consult with a patient the shape of newly made eyebrows.
As the donor hairs are from scalp, which are different in thickness and color of the eyebrows, we should take only thin and similar color hairs when dissecting process for making natural looking eyebrows.
Eyelashes can make the eyes look bigger and deeper. The most important thing in eyelash transplantation is its transplanted angle. The angle should be going upward in 30-40 degree to look natural and keep the eye from sticking by the lashes. Approximately 20 hairs are transplanted on each eye and the new lashes need to be cut by periods because they grow continuously.
The transplanted hairs must be thin and short vellus hairs so separate them under the microscopic dissecting.
Likewise, to make natural looking eyelashes, we should use vellus hairs. There would be no scars left after 2dyas later.
