Robotic hair transplant surgery is a significant advance in the technology of the Follicular Unit Extraction (FUE) procedure.

In Robotic FUE, the ARTAS® Robotic System automates the harvesting of follicular unit grafts, enabling an FUE hair transplant to be performed with unparalleled precision. The advantages of FUE over traditional hair transplants are having no linear scar in the donor area and having no post-operative limitations on physical activity.

The ARTAS robot’s advanced optical guidance system locates and extracts follicular units according to specifications programmed by the physician. It carries out this process hundreds to thousands of times per session with speed and accuracy that is impossible to duplicate with the human hand. The robot can also create recipient sites for the placement of follicular unit grafts according to an aesthetic plan designed by the physician.

Bernstein Medical’s Robotic Hair Transplant Center of New York® is among the first facilities in the world to utilize the ARTAS robot to perform FUE, a procedure pioneered by Dr. Bernstein. Our practice is a beta-test site for this innovative hair restoration technology. Dr. Bernstein is a medical adviser to Restoration Robotics, the company that manufactures the ARTAS hair transplant robot.

In addition to enhancing the core technology, Bernstein Medical has introduced new applications of the robotic system including custom punch sizes, robotic recipient site creation and follicular unit graft selection. Every FUE procedure at Bernstein Medical is performed using the ARTAS Robotic System.

Robotic FUE Advantages

FUE, which was first described and popularized by Drs. Rassman and Bernstein in 2002[1], requires surgeons to extract hundreds to thousands of follicular units in a single session. Using hand-held instruments, this is a labor-intensive process that subjects the patient to significant human variability and error.[2]

In manual FUE procedures, the doctor visually selects the follicular units to be extracted, estimates the angle the hairs grow out of the scalp, centers the extraction tool over the unit, incises the skin at a specific angle and depth, and then manually removes the follicular unit graft from surrounding tissue. The smallest deviation with a hand-held instrument can “transect” (damage) the follicular unit rendering it of little value in the transplant. The ARTAS Robotic System helps to minimize transection caused by human error and thus improves the quality of the hair restoration procedure.

The ARTAS robot also minimizes human error in the creation of recipient sites – tiny holes created in the balding area of the scalp where grafts are placed. There are several parameters in the creation of recipient sites that affect the aesthetic outcome of the transplant. Some of these include the angle of hair elevation, hair direction, site depth, average density or spacing, and the total number of recipient site incisions.

The physician uses the ARTAS system to program these parameters and the robot executes the plan with greater precision, speed, and consistency than can be accomplished manually. Read more about robotic recipient site creation.

The robot’s software allows the physician to specify which size follicular units to harvest and thus enables the doctor to select those containing the most hair. This has many benefits, but most important are to minimize donor wounding and make the process more efficient. Read more about robotic graft selection.

Potential advantages of robotic procedures over manual FUE

  • Increased accuracy of graft harvesting
  • Increased survival of harvested follicular units
  • Reduced harvesting time
  • Computerized selection of follicular units to maximize hair and minimize wounding
  • Easier extraction of grafts from the sides of the scalp
  • Easier extraction of grafts in patients from different racial backgrounds or with atypical hair characteristics
  • Increased speed and accuracy in creating recipient sites

Dr. Bernstein collaborates with Restoration Robotics to improve the ARTAS system. Advances introduced at Bernstein Medical include more efficient harvesting, robotic recipient site creation, follicular unit graft selection, an enhanced user interface, pre-making recipient sites and a variety of other important modifications described below.

Bernstein Medical was the first practice to offer customized punch sizes to suit the individual patient. A 0.9mm punch (the standard is 1.0mm) shortens healing time, decreases donor scarring, and increases the number of follicular units that can be harvested without damaging neighboring follicles. The smaller punch also creates grafts that require less trimming of the tissue that surrounds the follicular unit. Some patients, especially African-Americans, have less transection with the larger punch, so the ability to customize the tool to the patient can have a significant effect on the outcome of the transplant.

The physician can now use the ARTAS hair studio to guide the robotic in creating recipient sites. The physician inputs the hair restoration design and specifies the angle, depth, distribution and spacing of recipient sites. The robot then proceeds in making these sites with the same uniformity and precision that it used to harvest grafts. An important capability or the robot is the ability to avoid existing hair when creating these sites – a task very tedious to carry out by hand.

The ARTAS hair transplant robot at Bernstein Medical is programmed to skip over 1-hair follicular units. By avoiding the smallest follicular units, the robot harvests more hairs per extraction attempt and, thus, creates less wounding and scarring in the donor area. If smaller FUs are needed, such as to create a natural-looking hairline, robotically-extracted follicular units of 3 or more hairs can be dissected into smaller units. The Bernstein Medical team uses its expertise at stereo-microscopic dissection, gained over years of performing FUT hair transplants, to enhance the robotic procedure.

Another important modification of the FUE technique introduced at Bernstein Medical is pre-making recipient sites.[3],[4] Using this strategy, recipient sites are created before follicular units are extracted in a typical one-day procedure (or at the beginning of the first day in a two-day procedure). As soon as harvesting is complete, grafts are placed into recipient sites. This minimizes the time grafts are outside the body, increases visibility when placing the grafts (due to less bleeding), minimizes graft popping, and allows the recipient area to start the healing process earlier. A better environment for newly transplanted grafts increases the chances that they will survive the transplant and increases the likelihood of a positive aesthetic outcome.

The ARTAS system is comprised of a robotic arm with extraction and site creation capabilities, a video imaging system, and a computer user interface. The extraction mechanism is a double-punch arrangement with an inner (sharp) punch and outer (dull) punch.

During extraction, the inner punch scores the upper-most part of the skin and mild suction stabilizes the skin and allows the robot to follow the movements of the patient’s head. The rotating blunt edge of the outer punch then dissects the follicular unit from the surrounding tissue. This minimizes mechanical trauma and injury to the grafts. The entire process uses image-guided technology, allowing this step to be accomplished with microscopic precision.

The robot also has the ability to create recipient sites according to the physician’s specifications using an imaging and design technology called the ARTAS Hair Studio. Read more about the ARTAS Robotic System for FUE.
