What are the steps in Follicular Unit Transplantation technique? - Dr. K Prapanna Arya

Following are the steps followed for Follicular Unit Transplantation. First preparation of the donor area. Local anesthesia is used for the entire procedure. The donor area that is the occipital area is trimmed for about 2 to 4 mm and local anesthetic solution is injected just below the donor area. The next step is harvesting. The donor area is harvested with a single bladed knife. The hair in the lower part in the occipital area and the temporal areas are finer and they should be used to form a hairline. After the strip is harvested, it can be closed with staples or sutures. The next step is strip preparation. The harvested donor strips are immediately immersed in chilled normal saline. The proper hydration of the donor grafts with proper saline is very import throughout the surgery as it increases the survival rate throughout the grafts .if a single large strip is to be harvested, it can be divided into smaller pieces or sleevers before cutting the individual grafts. Graft dissection with a dissection stereomicroscope, a little slower, but it is much more accurate. The next step is the preparation of the recipient site. Anesthesia for that includes a supratrochlear and a supraorbital nerve block followed by a ring block in the frontal area beyond the zone of hair transplantation. While making the slits, or while using the implantors, it is very essential to follow the directions of the existing hair in that region. The hairline should have a roughened or a saw tooth like appearance to give a natural look. About 250 to 300 micrografts are necessary to create a natural hairline. The grafts are placed in to the slits using a fine angled forceps. If an implanter is used, you will not generally need a forceps. It is important to use an atraumatic technique in graft placement. A steady pressure is employed to ensure that the grafts are flushed with the surrounding skin. The grafting session can last upto 5 to 6 hours in which 2000 to 3000 follicular units may be transplanted.
