Earlier this month, Bernstein Medical physician Dr. Robert M. Bernstein presented at the annual ARTAS Users Meeting in Las Vegas, Nevada discussing the newest hair restoration techniques and the upgrade of the ARTAS 9x. Over 200 medical professionals met to share their knowledge of and experience with the ARTAS Robot for hair restoration.

Dr. Bernstein Presents Advances of the ARTAS 9x Robotic Hair Transplant System

On March 9th, 2018 at the 2018 ARTAS Users Meeting in Las Vegas, Nevada Dr. Robert M. Bernstein, a Clinical Professor of Dermatology at Columbia University and founder of Bernstein Medical – Center for Hair Restoration, presented the latest in Robotic Hair Transplantation using the ARTAS® Robot. Dr. Bernstein described the benefits of the new technology, such as decreased time and increased accuracy of the robotic procedure.

Dr. Bernstein worked with ARTAS engineers in the development of these new advances and tested them in our New York facility. These updates make Robotic FUE a faster and more efficient procedure.

The ARTAS 9x includes software and hardware updates such as white LED lights that are easier on the users’ eyes, a base extender, smaller size needle options, a more ergonomic headrest, automated scar detection, faster harvesting, and streamlined ARTAS Hair Studio software.

One important upgrade of the ARTAS 9x is the use of white LED light and yellow colored tensioner. This allows technicians to extract the grafts while the system is still harvesting the hairs — without causing eye fatigue. This advance alone can significantly reduce operating time. The base extender and the smaller robotic head of the ARTAS 9x allows for a longer reach so less repositioning of the patient is needed.

The ARTAS 9x also has artificial intelligence that detects and blocks out existing scarred portions of the donor area from being harvested. The streamlined ARTAS Hair Studio of the ARTAS 9x only requires one picture to create a 3D image of the patient’s scalp, while the previous version needed multiple.

Long-Hair Robotic FUE

Dr. Bernstein discussed Long-Hair Robotic FUE and its immediate cosmetic benefit to the patient. Traditional FUE procedures require the hair in the entire donor area to be clipped close to the scalp leaving a wide band of the harvested area visible. In Long-Hair FUE, the patient grows his hair longer on the back and sides of the scalp which can then be used to cover the harvested area. Dr. Bernstein explained that before the procedure the surgeon lifts the hair up and clips a long thin band of donor hair and then extracts the follicular units from this part of the donor area. After the procedure, the patient can comb his hair down to cover this harvested area. He explained how this can be done through one long band or, when more grafts are needed, two parallel bands in order to harvest the maximum number of grafts.

Dr. Bernstein Presents Advanced Robotic Hair Transplant Techniques at 2017 ARTAS Users Meeting

Dr. Bernstein closed the 2017 ARTAS Users Meeting with a discussion of five advanced techniques in robotic hair transplant procedures that he developed at Bernstein Medical. His presentation covered the benefits of pre-making recipient sites, long-hair FUE, tensioner placement, feathering edges in harvesting, and robotic graft selection. The “Hair Restoration Pearls” presentation included case studies, photographs, and videos demonstrating the techniques to the audience of hair restoration physicians. The two-day affair; which was held in Coronado, California; was a huge success, with over 260 attendees from around the world representing 204 robotic hair restoration practices.

Pre-Making Recipient Sites
There are several advantages of pre-making recipient sites in Robotic FUE procedures. One of the most important is that grafts are out of the body for a shorter period, which increases graft survival. During placement, there is less bleeding and greater graft stickiness, which result in increased visibility for the physician, less graft popping, and up to a 30% decrease in placing time. By pre-making sites, the physician can determine the exact number of grafts needed in the hair transplant. Also, the healing process can begin in the recipient area in advance of placing. This creates a fertile bed of oxygenated tissue with factors that promote healing and the subsequent growth of the follicular unit grafts.

Long-Hair Robotic FUE

In Long-Hair Robotic FUE, the patient has their hair temporarily lifted with tape during the hair transplant surgery. The physician then harvests from the donor area in a linear configuration so that, after the procedure, the long hair is let down covering the harvested area. The long-hair technique can be applied using one harvesting row (which yields up to 1,600 grafts), a double-row (2,000 grafts), or two separate rows (2,400). Long-Hair Robotic FUE, using the ARTAS Robotic Hair Transplant System, allows the donor area to be camouflaged immediately after surgery and does not limit a patient’s ability return to work. It also makes robotic hair transplants more practical for women, who usually prefer not to shave their donor area.

Tensioner Placement

Dr. Bernstein discussed a new two-handed technique for applying the robotic tensioner to the patient’s scalp. The tensioner applies traction to the scalp, stabilizes the skin, limits bleeding, and provides a system of fiducials that the ARTAS robot “reads” for proper orientation. Dr. Bernstein showed a video in which he demonstrates the technique and discusses the importance of applying the silicon straps as vertically as possible to ensure the greatest tension and stability. The two-hand technique allows for reduced stress on the physician’s hands, better control, and more accurate placement of the tensioner. It also facilitates easier edge engagement to create tension on the skin in preparation for harvesting.

Feathering Edges
Feathering is a common technique to avoiding a squared-off, geometric look after the FUE procedure. It allows the patient to maintain a natural look while wearing their hair short after the procedure. Dr. Bernstein presented two different ways to feather using existing capabilities of the ARTAS system. Dr. Bernstein showed how the physician can both round the edges of the harvest area and decrease the density on the outer edges, with simple, reproducible techniques. Most importantly, he discussed the situations in which feathering is important and the ones in which it should not be used.

Robotic Follicular Unit Graft Selection

Robotic graft selection is an advance over the harvesting technique used in earlier iterations of the ARTAS robot. The robot previously harvested grafts at random. By creating a software algorithm designed to skip over one-hair units and select only the larger follicular units, the harvesting process improved in efficiency. According to Dr. Bernstein’s study, the clinical benefit is 11.4% more hairs per graft and 17% more hairs per harvest attempt using this technique. Larger follicular unit grafts can be dissected into one-hair units for use in the frontal hairline and other cosmetically important areas in order to create the most natural aesthetic outcome in the hair transplant while minimizing the number of recipient wounds.

Key Advance in Robotic Hair Transplants Presented by Dr. Robert Bernstein at 2016 ARTAS Users Meeting

Dr. Robert M. Bernstein, a Clinical Professor of Dermatology at Columbia University and founder of Bernstein Medical – Center for Hair Restoration, presented results of a study on a major new advance in follicular unit harvesting using the ARTAS® Robotic Hair Transplant System at the 2016 ARTAS User Group Meeting in Dana Point, CA on February 20, 2016. Dr. Bernstein described the clinical benefit of the new advanced graft harvesting capability, a technique with wide implications for the increasingly popular robotic hair restoration procedure.

Dr. Bernstein Presenting at the 2016 ARTAS User Group Meeting

New York, NY — Dr. Robert M. Bernstein, a pioneer of robot-assisted hair transplantation, presented results of a study on a major new advance in robotic follicular unit harvesting, a key step in the surgical procedure, at the 2016 ARTAS User Group Meeting in Dana Point, CA. He reported that the new robotic technique resulted in a clinical benefit of up to 15% more hairs per harvest attempt and 11.4% more hairs per graft than with the current iteration of the ARTAS® Robotic Hair Transplant System. The improvement in graft harvesting should result in better aesthetic outcomes for patients, and this will have wide implications around the world as robotic hair transplant procedures are booming in popularity. Dr. Bernstein presented the findings to a “who’s who” group in the new field of robotic hair restoration surgery at their annual meeting held on February 20th, 2016.

When asked about the significance of advanced robotic harvesting, Dr. Bernstein said:

“Through the hard work and ingenuity that went into developing the robot’s new graft selection capability, we have moved this new ARTAS application from the ‘proof of concept’ phase into an enabling technology that improves patient care.”

In robotic follicular unit extraction (Robotic FUE) hair transplants, the surgeon seeks to harvest as much hair as possible through the fewest number of donor sites. By maximizing the hair-to-donor wound ratio, they can maximize the cosmetic benefit of the procedure. The ARTAS robot’s new advanced graft selection capability uses its updated computer algorithm to determine which of the hundreds of follicular units — naturally-occurring groupings of one to four hair follicles — to harvest. By programming the computer to select only the larger follicular units (i.e., ones containing two or more hairs), the robot can automatically maximize the hair-to-wound ratio. The result is more hairs harvested with fewer post-transplant scars and an improved cosmetic outcome for the patient. Previously, the robot randomly selected follicular units to harvest.

To demonstrate the benefit of advanced automated graft selection, Dr. Bernstein presented findings of a randomized, bilaterally-controlled study performed on robotic FUE patients at Bernstein Medical – Center for Hair Restoration. The robot was programmed to select follicular units of two or more hairs in a first pass, and then all follicular units in a second pass. The control for the experiment was an area, on the contra-lateral side, that was harvested with the graft selection capability disabled. The first pass yielded 15% more hairs per harvest attempt and 11.4% more hairs per graft compared to the control. The second pass yielded 12.3% more hairs per harvest attempt and 6.4% more hairs per graft. These findings suggest that there is a significant clinical benefit in using the advanced graft selection capability when compared to random selection of follicular units.
