1. During a hair transplant procedure operated with the Choi implanter, the specialized physician/surgeon or technicians transmit the harvested grafts into the implanter pen.

    The graft is inserted gently within the hollow needle, which is positioned at the end of the implanter pen, to be handed back to the specialized physician.

  2. Subsequently, the needle is inserted at an accurate angle of 40-45 degrees into the scalp by the surgeon, as the incision site is made and then the graft is implanted by pressing down on the plunger.

  3. During a procedure, normally an amount varying from 2-6 Choi implanters and approximately 15-16 needles are concurrently used, with the device coming in a variety of needle sizes to fit the follicular unit grafts.

The Choi method naturally has its advantages as well as its disadvantages over the FUE technique.

Advantages of DHI Technique

Among its advantages indicated by some hair restoration experts are as follows;

  • Reduced time of grafts remaining outside the body, thus ensuring strong and healthy placement of the grafts.
  • Adequate hair follicles survival rates.
  • Reduced bleeding during the creation of the recipient area. Reduced trauma during graft handling, thus leading to less damage in the blood supply to the implanted area.
  • Fast recovery during the postoperative phase, the patient can return back to his/her normal routine quicker.
  • The recipient site does not have to be shaved, as it is a more suitable procedure that enables this condition.

Disadvantages of DHI Technique

On the other hand the disadvantages in comparison to the FUE method include;

  • The physician and staff members are exposed to long-term training period so as to specialize in utilizing this technique.
  • It is generally a more costly procedure when compared to other hair transplantation methods.
  • This method requires more attention as well as accuracy during the procedure.
  • Due to the fact of the limitation of access to the operative area- this technique can cause the operator stress, which could likely affect both the extraction as well as the implantation process, causing possible damage while handling the grafts.
