Traditional Stripe Method of FUT
Step 1: Donor Harvesting
The goal of donor harvesting is to remove tissue of scalp from the permanent donor area in a way that limits transection of hair follicles. In addition, minimal scar should be minimal and possibly detectable.
A stripe of scalp having with about 1-2 cm and length of about 20-25 cm is removed from permanent donor area.
This donor site closure is done with trychophytic closure .
It is important to remain within the permanent fringe area when removing the donor strip because if grafts taken from outside this area, those prepared grafts may be lost as time progress. Patient with tight scalp are poor candidate for strip technique.
Step 2: Graft Preparation
- The strip- harvested donor tissue is converted into grafts in two steps.
- Slivering: Donor strip is cut into thin slices or slivers containing single row of follicles. This procedure is performed under microscope or magnification.
- Grafts or FU dissection: from these slivers, individual units containing 1-4 follicles are separated under magnification.
- All grafts are store in retaining solution usually Chilled Ringer lactate solution.
- Temperature is maintained below 4 degrees.
Step 3: Creating Recipient Sites
Reciepient site incisions vary in size from 0.65 to 1.2 mm wide, with smaller incisions used for 1to 2 hair FUs and larger incisions are used for the 3-4 hairs FUs or curly hairs. While making slits the surgeon should create a pattern that imitate nature. he incisions also have to enter scalp at same direction and angle as the pre-existing hair follicles.
Step4: Placing Grafts:
The skill and ability to place grafts successfully is a critical step in hair ptransplant surgery. The potential for graft trauma leading to poor growth occurring at this step is high. Fine tipped Jewelers forceps are used for placing grafts in slits. During this procedure loop magnification is essential to avoid injury to hair follicle.
