Fue Hair Transplant Excision (Harvest)
It is important not to cause a deficiency in the harvest area during root harvesting. In patients whose hair root density is more than 1.5 mm, 2 to 1 harvest is made. Harvest rate is 3 to 1 for sparse hair from 2mm.
The harvest area is the oxipital area, when the harvest area expands towards the nape and top, it becomes difficult to obtain healthy roots. Before the harvest, donor area borders are determined with a surgical pen. A mixture of Bupivacaine (brandin) and Lidocaine + Prilocaine (citanest) is used for anesthesia. The mixture is adjusted according to the desired anesthesia time.
Bupivakain (marcaine) has an effect time of up to 10 hours. However, the effect is increased 30-45 minutes after the application. The effect of Lidocaine + Prilocaine (citanest) starts within 5 minutes and lasts for 2-3 hours.
First of all, regional anesthesia is performed by taking into account the oxipital region anatomy. Block anesthesia performed correctly provides sufficient anesthesia with minimum pain. However, most doctors prefer to strengthen anesthesia by turning the intake area into a frame.
Bringing the anesthetic to body temperature before the procedure and cooling the tissue reduces the pain and burning sensation during anesthesia. The use of needle-free injection pens does not reduce the pain and burning sensation, contrary to popular belief.
After anesthesia, an inflation called thymocele is applied to the receiving area. It helps to straighten the thymocel root pains, to remove the dermis from the vascular nerve packs and to control bleeding. It is 1/10000 serum containing low dose adrenaline. The amount of adrenaline used for bleeding control must be kept at the minimum dose due to the risk of systemic side effects and surgical necrosis. Generally, 1 ampoule 0.5 adrenaline in 100cc mai provides bleeding control.
High-dose adrenaline-containing mailer or excessive thymocele applications can invite necrosis. The pallor of the tissue after the application indicates that high adrenaline or excess thymocele was applied.
HARVESTING
Harvest is made with punches of 0.6-0.8, the diameter of which is determined according to the patient, larger diameter punches will delay wound healing in the removal area and also negatively affect the frequency of sowing as larger tissue pieces will be removed.
The post-harvest area must be carefully covered with special medical materials. We use wound care products in our clinic for this purpose.
During the harvest, the roots are carefully washed in petri dishes and arranged accordingly. The broken roots are selected and packaged in the refrigerator and removed. It is vital that the roots and surrounding tissue are not dried. Especially in high-graft operations, channel opening can be taken forward in order to shorten the time that the roots remain outside.
