Although FUE is considered to be minimally invasive technique ,the injury to the donor area caused by scoring with a punch, during donor harvesting is still of concern to patients and FUE hair surgeons, because when healing is complete multiple small white dots known as hypopigmentation can be noticeable .The increased scar formation or fibrosis from wound healing is not only an important cosmetic problem for a patient with very short hair but it also results in a donor site that potentially makes a future FUE procedure problematic.
To efficiently manage the problem Dr Zontos has innovated a technique named Vertical Extraction .Using this technique during the harvesting process both physician and patient can benefit from its application during FUE. Specifically VE minimizes injury to the donor area, while allowing for an easier and more efficient extraction. Based on the premise that the higher the initial trauma , the higher the degree of scarring will be, then we can suppose that VE can limit scar formation on the donor area in FUE. This implies an important improvement to the condition of the donor area, especially during a subsequent FUE session.It is well known to FUE hair surgeons that any follow-up FUE session after a large one may be compromised and associated with technical difficulties such as high transection and low harvesting rates. To clarify, when scar formation or fibrosis is extensive, increased force of friction exerted on the punch, causing follicular displacement and higher transection rate. The latter inevitably results in further injury to the donor area. As more harvesting attempts are required to obtain the desired number of grafts the scar formation from wound healing is increased. Moreover, because the scarring on the donor area is additive, the necessity of decreasing the injury to the donor area becomes very demanding.
