This depends on how many grafts are going to be transplanted. Generally under 1,000 grafts can be transplanted in a single day. In my clinic, and in select clinics in the USA, cases over 1,000 grafts are split into 2 separate days: an afternoon, followed the next morning by an early start the next morning. At 1pm on Day 1, patients arrive and we go over the consent forms, take the necessary pre-operative photographs, trim the hair for the ARTAS procedure (to be performed first thing in the morning the next day), anesthetize the scalp, perform the PRP with ACell procedure, and make all of the recipient sites for the grafts that will be transplanted. Then, the following morning the patient returns to our Center for the ARTAS procedure. The scalp is anesthetized, and the extractions begin with the ARTAS robot. As soon as the extractions are completed, the patient is escorted to the placement room, and with zero delay, the grafts are placed into the recipient sites created the previous day. This has two advantages: (1) it minimizes the time the grafts spend outside of the head, and (2) it gives the scalp a near 24 hour head start on the neovascularization of the new sites. Both of these greatly help to keep the survival rate of the transplanted grafts at a maximum.
