Q: Is it true that performing FUE hair transplant procedures by hand is better because the physician can better adjust and feel the follicle when extracting? — M.H. ~ Great Neck, N.Y.
A: The ARTAS robot is a physician controlled, computerized device that uses a three-dimensional optical system to isolate follicular units from the back of the scalp in a hair transplant. The robotic system assists the physician in the extraction of grafts with precision and speed. Although there is some advantage to having “human feel” for the tissue, this is far outweighed by the fact that repetitive procedures performed manually thousands of times lead to operator fatigue and result in increased transection and damage to grafts. With the ARTAS robotic system, the quality of the first and the last graft harvested will be the same.

Dr. Bernstein presented results of his study, “Robotic Follicular Unit Graft Selection,” at the 2016 ISHRS World Congress held in Las Vegas, Nevada. Graft selection is a key advance in the ARTAS Robotic Hair Transplant System, a hardware and software suite that automates aspects of the Follicular Unit Extraction (FUE) hair transplant procedure. The enhancement makes Robotic FUE more efficient and improves patient outcomes.
A 2014 study in the journal Dermatologic Surgery measured follicular unit transection (follicle damage) during the extraction step of a robotic follicular unit extraction (R-FUE) procedure. The study found that robotic transection rates, using the ARTAS Robotic System, compared favorably with non-robotic (manual) FUE transection rates.
Posted by Updated 2017-10-06Q: What is the main difference between hair transplants using the robot versus other procedures? — M.P., Flatiron, NY
A: There are two basic types of hair transplant procedures, Follicular Unit Transplantation (FUT or strip surgery) and Follicular Unit Extraction (FUE). In FUT, donor hair is harvested by removing a long thin strip from the back of the scalp. Individual follicular units are then obtained from this strip using stereo-microscopic dissection. In FUE, individual follicular units are harvested directly from the donor area using a sharp, round cutting instrument. The ARTAS Robotic System performs the follicular unit isolation step of an FUE procedure and can also create recipient sites according to specifications determined by the hair restoration surgeon. In performing each of these steps, the robot uses its image-guided technology to locate the next target and position the cutting instrument, and it does so with precision and speed that cannot be accomplished using manual FUE techniques or instruments.

Dr. Robert M. Bernstein introduced a new capability of the ARTAS® robotic system, “Follicular Unit Graft Selection,” at the ARTAS User Group Meeting on February 6-7, 2015 in Newport Coast, CA. He presented the new technology and the preliminary results of a bilateral pilot study of the technique conducted at Bernstein Medical.
Posted by Updated 2018-07-03Q: Does Follicular Unit Extraction performed by a robot hurt more than regular FUE? — R.T., Greenwich, CT
A: As with manual FUE, robotic FUE hair transplantation is an outpatient procedure performed under long-acting local anesthesia – a combination of lidocaine and bupivacaine. After the initial injections, the patient does not experience any pain or discomfort.
Before starting local anesthesia, we give most patients oral valium and intra-muscular midazolam (a very fast acting sedative that is very relaxing). While some patients doze off at the beginning of the procedure, others prefer to watch TV, a film, or just chat.
Local anesthesia generally wears off after 4-5 hours, so for transplant sessions lasting longer than this, we will give more anesthesia before the first wears off. With Robotic FUE, there is no discomfort once the procedure is completed and the anesthesia wears off. This is in stark contrast to an FUT strip procedure which can be uncomfortable in the donor area for days to weeks.
Posted by Updated 2017-10-17Q: How many follicles can you transplant with robotic FUE compared to manual FUE? — R.V., Upper West Side, N.Y.
A: We can extract the same number of follicles robotically as we can manually.
That said, the goal of any hair transplant procedure is not to transplant as many hair follicles as possible but rather to achieve the best possible cosmetic result given your degree of hair loss and the number of hair follicles available in your donor area.
Posted by Updated 2017-12-11Q: I have read a bit about the ARTAS robot and how it uses an “image-guided” system, but what does that mean? And how is the robot’s imaging system different than a human surgeon viewing the grafts with the naked eye? — S.V., Middle Village, N.Y.
A: That is a great question and it gets to one of the key benefits of the robotic hair transplant system: its accuracy. When a surgeon is performing FUE using manual techniques, they must wear a headset that magnifies the scalp so they can see the follicular units more clearly than with the naked eye. The surgeon must visually and mentally process subtle nuances of the skin and follicular units for every one of the hundreds or thousands of units that are extracted. The ARTAS robot magnifies the surface of the skin in much the same way, but to a much greater extent. In addition, it is not subject to the limitations of the human eye, or human hand, and it is not subject to human error. The surgeon may not have exact hand-eye coordination. The surgeon may be concentrating on one aspect of the extraction, say following the angle of the hair, but might ignore another important aspect of the follicle, say its depth in the skin or its orientation. And, of course, the surgeon tires, both physically and mentally, from performing the hundreds or thousands of repetitive motions.
The robot’s image-guided system, on the other hand, does not experience these limitations. The robot magnifies the skin, detects each follicular unit and the nuances of the skin/hair characteristics, and then extracts that follicular unit with precision. When the imaging system detects changes to the skin, this new information is fed into the computer in real-time and the system adjusts automatically based on this feedback as it continues to harvest grafts. There is no distracting the robot, and the robot will not forget, or ignore, key variables in the extraction. The robot can extract thousands of follicular units without tiring from repetition or slowing down the extraction.
Based on my own practical experience using the robot, it is clear that the robot’s ability to estimate the position of the follicles under the skin and to extract it with precision is superior to manual techniques. Having used the ARTAS system for over three years, and having helped make improvements to the device since the first iteration, I have seen robotic technology substantially improve the outcome for my patients.

Dr. Robert Bernstein discusses the benefits of the ARTAS Robotic Hair Transplant system in The Aesthetic Guide, a leading periodical in the field of aesthetic surgery. The article examines how robotic Follicular Unit Extraction (FUE) procedures are an improvement over FUE using handheld devices.
Posted by Updated 2015-08-14Q: Is robotic FUE different in the number of follicular unit grafts one can extract compared to manual FUE? — R.V., Stamford, CT
A: We can extract (and transplant) the same number of follicular unit grafts robotically as we can manually.
The goal of a hair transplant is not to simply transplant as many grafts as possible but to achieve the best possible cosmetic result given the number of hair follicles in your donor reserve. Remember, this is always a limited supply.
While there is no difference between robotic and manual FUE in terms of the number of follicular unit grafts that each can extract, robotic FUE does differ from manual FUE in several important ways.
First, there is generally less transection of the hair follicles with robotic FUE, since the method is more precise. This enables us to obtain follicular units with less trauma to the grafts.
Second, while the robot is not necessarily faster than the human surgeon, the robot is much more consistent since, unlike the human surgeon, it never fatigues and the accuracy is maintained throughout the entire procedure.
Posted by Updated 2018-07-03Q: Does transplanted hair grow faster after a robotic FUE? — P.P., Flatiron, NY
A: There is no difference in the rate of growth between manual FUE verses robotic FUE. However, with robotic FUE, the actual growth should be better due to less transection (damage to follicles during the harvest).
In general, one can expect transplanted hair to start to grow within two to five months with the transplanted hair taking on its final appearance after approximately one year.

Posted by Updated 2017-12-11Q: I’ve heard that robotic-assisted FUE is better than manual FUE, but what exactly is the main advantage of Robotic FUE? — N.K., Bergen County, NJ
A: Robotic FUE is a significant improvement over other FUE techniques for a number of reasons. The accuracy and ability of a robot to perform countless repetitive motions are key reasons why robotic techniques are an improvement over manual techniques.
In a manual procedure, the skill and speed of a physician are under constant stress, as he or she must follow the angle and depth of the hair precisely hundreds to thousands of times. This task is almost impossible for even the best surgeons to perform without risking harm to the integrity of the follicles. Entering the skin at the wrong angle risks transecting or cutting the follicles and may render them useless for transplantation. Making too shallow an incision can also damage follicles, as the important base of the follicle can become sheared off when it is subsequently extracted.
The robot is engineered to avoid these problems, and so the number of viable grafts that the robot extracts is increased. As a result, the likelihood of the success of the transplant is greater using the robotic system.
