Q: Why is using the robot to create recipient sites useful in a hair transplant? — S.K., Jersey City, NJ

A: The ARTAS® Robotic Hair Transplant system eliminates the inconsistencies inherent in creating large numbers of recipient sites by hand. The robot can create sites at a rate of up to 2,000 per hour. Although there is more set-up time compared to sites made manually, once the physician specifies the parameters such as punch depth, punch angle, and site direction, recipient site creation is precise and rapid.

One of the benefits of robotic site creation is that the distribution of grafts over a fixed area of the scalp can be exact. For example, if one wants to transplant 1,000 grafts evenly over 50cm2 of area, this can be done with great precision and with uniform site spacing. In addition, the physician can vary the densities in select regions of the scalp and the robot will adjust the densities in other areas so that the total number of sites remains the same.

Another benefit of the new technology is that the robot can be programmed to avoid existing hair and select which specific hair diameters to avoid. The robot is programmed to keep a specified distance from the existing hair to ensure that the resident follicles will not be damaged and that the distribution of new hair is even and natural. This computerized mechanism appears to be more accurate than what can be done by hand and, importantly, does not sacrifice speed in the process.
