Small, simple modifications in the sequence of the major steps in a Follicular Unit Extraction (FUE) hair transplant procedure will be beneficial to healing and growth following the procedure, says renowned hair restoration surgeon Dr. Robert M. Bernstein. Presenting at the 23rd Annual Scientific Meeting of the International Society of Hair Restoration Surgery (ISHRS) in Chicago, Illinois, Dr. Bernstein detailed how making recipient site incisions before harvesting follicular unit grafts can improve the outcome of an FUE procedure.

For years, it was standard operating procedure in an FUE hair transplant to first harvest follicular units, then create recipient sites in the balding areas and place the extracted units into these sites. This practice persisted despite the fact that hair restoration physicians had known for years that prolonged periods of time outside the body decreased survival of follicular unit grafts. With the widespread adoption of FUE, and the long time needed for the extraction phase of the procedure, Dr. Bernstein looked for ways to streamline the process.

By making the requisite number of recipient sites before harvesting, the grafts can be placed as soon as they are extracted. This reduces the critical period of time that grafts are out of the body. Sites created before harvesting have more time to begin healing, and so they exhibit less bleeding. This results in fewer grafts that “pop” out of the recipient site during placement. Mechanical trauma to grafts that need re-positioning after popping is also reduced. Allowing time for recipient sites to begin healing might also provide a more fertile bed for newly implanted grafts to take root. Additionally, pre-making sites provides time for crusts to form on the surface of the wound. Removing these crusts before placement decreases post-operative inflammation and promotes wound healing.

Dr. Bernstein proposed that in some large FUE sessions, in which large numbers of follicular units are transplanted, the surgeon might deliberately delay extraction to allow pre-made recipient sites additional time to heal by creating recipient sites the day before harvesting.

In sum, Dr. Bernstein provided the audience of hair restoration surgeons with a practical modification of the traditional FUE procedure that could impact the outcome of every hair transplant. Given the growth in the number of FUE hair transplants being performed (now about 50% of all hair transplant procedures) and the international platform provided by the ISHRS Annual Scientific Meeting, this small procedural adjustment could have a significant benefit for thousands of hair restoration patients around the world.

Q: How do recipient sites get made in Robotic FUE? And how does the robot know where to create the sites? — K.K., Bergen County, NJ

A: In performing recipient site creation, the ARTAS Robotic Hair Transplant system automates another part of the hair transplant process that is repetitive and prone to human error. In robotic site creation, the physician first designs the hair restoration and then specifies the angle of hair elevation, hair direction, site depth, average density, and total number of the recipient site incisions. The robot then creates the sites according to these specifications.

During site creation, the robot automatically uses its image-guided technology to avoid hairs of a certain diameter (specified by the doctor). The robot creates sites at a minimum distance from hairs of the specified diameter (the distance is also specified by the physician) and will do so randomly throughout the areas where the hair is finer or the scalp is bald. With this important feature, the new distribution of sites can be made to complement the distribution of existing hair. Observation of the ARTAS System suggests that it performs recipient site creation with greater precision and consistency than can be accomplished manually.
