The basic answer to this question lies on the patient’s concerns. Most patients are scared of having a visible linear scar, others are scared of shaving off all the hair.
FUT and FUE are equally effective depending on the physician handling the case. There is no better or worse method. The patient needs to think about issues like if he/she minds having a scar depending on whether they want to wear their hair short or not, if they are fine with shaving or not. Another aspect to consider is the healing of the donor area; FUE patients heal faster since the method is less invasive.
The number of grafts that can be extracted in my opinion does not depend on the method; both FUE and FUT can harvest equally sufficient grafts.
On the overall outlook of the result, there is no difference in FUT and FUE since the result completely depends on the skill of the physician in creating recipient sites that would mimic the natural hair growth; and is completely independent of the harvesting technique.
Hair grows in tiny little groups of 1-4, called Follicular Units a concept that was discovered by Dr. Bernstein in 1995. The development of Follicular Unit Extraction FUE technique evolved to eradicate the permanent scar that results from the FUT method.
In FUE, circular trephine punches combined with high power magnification are used to extract the individual follicular units from the donor area, which are then transplanted to the recipient sites. This is such a delicate procedure, involving a lot of care and attention, not to damage the hair follicles.
The injuring or cutting off of hair follicles during the extraction is known as transection. Dr Civas has acquired experience and skills in hair transplantation, and has very low transection rates of around 3%. FUE allows versatility of punch size and depth therefore high graft quality. In Civas clinic we use punch sizes of 0.6mm for 1s Follicular Units, 0.8mm for 2s Follicular Units, 1mm for 3s and 4s Follicular Units.
FUE also gives the surgeon a chance to select the best hair follicles and regulate the number of grafts to be transplanted, hence high quality grafts with minimal invasion.
