Commentary on robotic follicular unit extraction in hair transplantation.

In their excellent article, “Robotic Follicular Unit Extraction in Hair Transplantation,” Avram and Watkin give a review of the salient aspects of the newly evolving field of robotic hair transplantation. A significant contribution of this article is the data on transection rates. The authors found that the mean transection rate of robotic extraction is 6.6% in their 20 cases. This compares favorably with manual extraction techniques. They stress the need for welldesigned long-term studies comparing the various harvesting techniques currently being used.
