Originating from an old technique of strip harvesting, there is a thin strip of skin which needs to removed from the back of the scalp and placed on the area of treatment. It was noticed earlier that the strip procedure is largely responsible for the unwanted results associated with donor scarring, bruising and hair plugs. The new advancement has changed the way we look at strip procedure and is now favoured by many surgeons mainly with the assurance for the great quality of hair grafts as compared to the earlier FUT procedure which required 7 long hours to complete a full head surgery.
Not only does it differ in the use of skin dissection of hair grafts from before, but also many other factors stated below:
- Use Of Local Anaesthesia
General anesthesia was used to perform the strip method previously, which is sufficed by the usage of local anesthesia of the treatable area to prevent excess blood flow.
- Use Of Single Blade Incision
Previously, what was multi blade incision is now a single blade scalpel. Not only has it reduced the chance of graft transaction while strip removal, but also helped to achieve what you always wished for.
This technique helps to perform an occasional relief of tension which occurs during the closing of the target area. Performed with the help of separating the skin layers around the edges of the suture undermining is performed to prevent slow healing, bleeding and scarring.
- Trichophytic Closure
This type of closure reduces the chances of scarring with well coordinated incision and systematic and closure patterns. This technique allows linear patterned growth of the existing hairs which can totally hide the slight scar that you may be carrying. Usually in this case the donor area is sutured than stapled.
- Use Of Absorbable Sutures And Staples
The donor wound can either be sutured or stapled, and both can reduce scarring. The benefit of choosing the staples is that it would cause lesser inflammation and result in lesser risk of damaging the existing hair after the completion of donor harvesting. This also reduces the chance of strangling the hair follicles with interrupted clipping as compared to the constant running stitch.
Among the sutures, there are chances of preferring the absorbable sutures as compared to the normal one as it would help to dissolve in the area targeted and allow the surgeon a greater precision of closing the donor area manually.
- Follicular Grafting
The normal course of a hair, mainly grows in a single hair follicle, but when it comes to hair placement there are 2-5 hair follicles close residing as a unit, known as follicular unit. The grafting process is abided by both FUE and FUT procedure for the best outcome.
