How Does the ARTAS Robotic System Make Recipient Sites in a Hair Transplant?

April 6th, 2015

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.

How Does Robotic FUE Differ from Other Hair Transplant Procedures?

April 3rd, 2015

Q: 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.

Does Propecia Work for Life or Does it Stop Working Over Time?

April 2nd, 2015

Q: Can Propecia (finasteride) completely halt androgenic alopecia for the duration of your lifetime, or does it just slow down the progression of androgenic alopecia? — L.B., Scarsdale, N.Y.

A: In many patients we have found finasteride to hold on to a patient’s hair for at least 15 years. We don’t have much longer data than that since it was approved for hair loss in 1998. Although finasteride will usually continue to work as long as you take it, it may lose some of its efficacy over time. Generally after about 5 years we may notice that the patient’s hair is starting to thin again and we will increase the dose slightly. It is important to understand that even if someone thins on finasteride it doesn’t mean the medicine is not working, because they might have thinned much more without it. To my knowledge, there are no studies that have looked at the effects of finasteride for such an extended period of time.

Melatonin Solution Found to Reverse Early Hair Loss in Men and Women

March 31st, 2015

Topical application of the solution containing melatonin, ginkgo biloba and biotin was found to reduce hair loss, and in some cases grow new hair. Incidence of seborrhea was also reduced by the treatment. While the exact mechanism for this result is unknown, if effective, it is likely related to the antioxidative effect of melatonin and/or a melatonin receptor-mediated antiandrogenic effects. More research on melatonin needs to be conducted, but this study acts as a proof of concept for the use of melatonin as a treatment for early hair loss in men and women and potentially as a treatment for seborrhea.

America’s Top Doctors Guide Includes Dr. Bernstein in 14th Consecutive Edition

March 26th, 2015

Dr. Bernstein is honored to appear among the top 1% of medical specialists in the country in the 14th edition of Castle Connolly’s America’s Top Doctors.

His inclusion is in recognition of his pioneering career in surgical hair restoration and the treatment of hair loss. Dr. Bernstein has been selected for every edition of the national guide.

High-Grade Prostate Cancer Risk Increases in Heavy Drinkers Who Take Dutasteride

March 24th, 2015

A new 4-year study, published in the journal European Urology, found that men who take dutasteride (part of a class of medications called 5-alpha reductase inhibitors) and who also drink heavily (more than seven alcoholic drinks per week) have a greater risk of developing high-grade prostate cancer than men who take dutasteride and do not drink.

How Does a Hair Transplant Surgeon Operate the ARTAS Robot for FUE?

March 11th, 2015

Q: I have been reading about Robotic FUE and have seen some photos on your website of you operating the ARTAS robot using what looks like a remote control. What is that thing and how does it control the robot? — C.B., Greenwich, CT

A: The ARTAS robot uses a dual operating system when performing follicular unit extraction. One station consists of a desktop computer adjacent to the robot. This station is used to establish the basic parameters of the transplant such as the spacing of grafts, the angle and depth of the harvest, which size follicular units will be targeted, and a host of other important variables.

The hand-held pendant is used by the operator situated next to the patient. The remote has more limited options – the main ones being depth adjustment and to immediately suspend the action of the robot. Many of the parameters are determined automatically by the robot’s computer to maximize the accuracy of the harvesting. The robot also makes real-time adjustments to these variables during the hair restoration procedure.

The physician sets the parameters at the computer monitor and, once the settings are determined, he/she sets the tensioner grid on the patient’s scalp. The tensioner determines where the grafts will be harvested. The grid is moved approximately every 130 harvests. The robot can be operated at the computer terminal and through a mobile pendant. The physician often alternates with a trained assistant between that station and using the pendant.

Besides the involvement in the operation of the robot, there are many other important physician-dependent steps to the hair transplant including the planning and design of the procedure, and recipient site creation. Other steps, such as the microscopic sorting and trimming of harvested follicular unit grafts and graft placement, are often performed by trained staff, but require the physician’s close supervision.

Commentary on Robotic FUE in Hair Transplantation

March 10th, 2015

Synopsis: 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. As the authors state, the appeal of robotic FUE is part of the “inexorable trend” toward minimally invasive surgical procedures. As with any new technology, it is up to the practicing physician to make sure that it is used appropriately and to the maximum benefit of our patients.

ARTAS Robotic System Provides Minimized Donor Area Scarring

March 8th, 2015

Synopsis: The ARTAS® Robotic System provides a unique, comprehensive suite of tools that physicians can use to minimize donor area scarring and offer the patient greater styling options post-surgery. Factors that influence scarring in the donor area include: dissection punch size, density of harvest sites, distribution of the harvest sites, total number of sites, and the ‘blending in’ of harvest zones with un-harvested areas.
