Robotic Follicular Unit Extraction in Hair Transplantation
Marc R. Avram, MD,* and Shannon A. Watkins, MD†
BACKGROUND In recent years, there has been a shift toward minimally invasive procedures. In hair trans- plantation surgery, this trend has manifested with the emergence of follicular unit extraction (FUE). Recently, a robot has been introduced for FUE procedures.
OBJECTIVE- To determine the transection rate of a robotic FUE device. In the attached article, the authors discuss the procedure, technical requirements, optimal candidates, advantages, and disadvantages of robotic FUE compared with the standard ellipse.
RESULTS- Optimal candidates for robotic FUE are those with dark hair color who can sit for 45 to 120 minutes and are willing to shave a large area for donor harvesting. The main advantages of robotic FUE compared with the standard ellipse are its minimally invasive nature and the lack of a linear scar.
CONCLUSION- The robot is a new and innovative method for FUE hair transplantation of which hair transplant surgeons should be aware.page1image10600 page1image10760
In the 1990s, hair transplant surgery underwent a revolution in the graft size used for transplantation. From the 1960s into the mid 1990s, 2 to 4 mm grafts containing 10 to 20 hair follicles were the standard graft used in the procedure. In spite of its scientific success, they were often a cosmetic failure because they resulted in a “pluggy” unnatural appearance. In the 1990s, there was a shift toward smaller graft sizes. Currently, the follicular unit, which contains 1 to 4 hair follicles, is the standard graft size used in transplant surgery.1,2 This shift in graft size has allowed patients to consistently grow naturally appearing transplanted hair, as it mimics the natural size of follicular groupings on the scalp1 (Figure 1). In addition, the use of follicular groupings eliminates textural changes and scarring in the recipient area. Large grafts containing 10 to 20 hair follicles required larger recipient sites, which resulted in unnatural “cobblestone” scarring on the scalp. Recipient sites for follicular groupings are less than
In the era of follicular unit transplantation, the only visible scar on the scalp is the linear scar left from the donor ellipse. For the majority of men and women, a linear scar has no short or long- term practical effect. Their existing donor hair will camouflage the scar. A linear scar can create an issue, however, for some patients who wear their hair shorter or want the option of a shorter hairstyle in the future. In addition, there has been an inexorable trend in all surgical procedures toward minimally invasive procedures, which result in less scarring and quicker recovery times.
Donor Harvesting Techniques
Over the past several years, the focus of discussion in the field has begun to shift away from the size of the graft used to transplant hair toward the harvesting method used to obtain the donor grafts. For decades, 2 to 4 mm punch trephines were used to obtain donor hair from the posterior scalp. Typically, the grafts were removed and wounds were allowed to heal by secondary intention. This resulted in widespread “hon- eycomb” scarring (Figure 2). In 1994, the concept of elliptical donor harvesting, also known as strip har- vesting, was introduced and has been the standard method for obtaining donor grafts.3 It is based on the same dermatologic surgery techniques used in removing nevi, skin carcinomas, and cysts. It allows efficient harvesting of hundreds to thousands of fol- licular groupings. As with any cutaneous excision, there is a scar created from removing the donor ellipse. For the majority of patients, this is neither a medical nor a cosmetic issue. For a minority of patients, medical and cosmetic challenges may arise. A small percentage of patients will develop hyper- trophic or broad scars. Others feel limited in the hair styling options because of the donor scar. For these
Follicular Unit Extraction Versus Elliptical Donor Harvesting
The concept of follicular unit extraction (FUE) was introduced in the early 21st century and refined over the past decade.4–6 Follicular unit extraction used the same concept of using a steel trephine to harvest donor hair, but instead of being 2 to 4 mm in diameter as was used in the past, the FUE punches range from 0.8 mm to 1.2 mm. This technique is a natural extension of the concept of follicular unit hair transplantation—the utilization of individual follicular groupings in the recipient and donor sites.
Challenges of this technique include the following: increased risk of transection of hair follicles, operator fatigue when harvesting hundreds of follicular groupings, and appropriate spacing of harvested grafts to yield the maximum amount of donor hair without creating the appearance of a depleted donor density.6 Throughout the posterior scalp, the angle of hair growth varies, which presents a challenge to surgeons. Magnification and excellent lighting reduce but do not eliminate the risk of transecting follicles. Compounding this challenge is the need to remove dozens to many hundreds of follicular groupings for each case. Harvesting larger numbers of grafts can result in increased operator fatigue and a higher rate of transected hair follicles. Some experienced sur- geons are able to harvest large numbers of follicular groupings with minimal transections, but others are unable to do so.
To improve the accuracy and efficiency of FUE, numerous FUE devices have been developed; of which some are motorized, some are suction assisted, and some are single user-directed robotic system. The NeoGraftautomatedhairtransplantsystem,7–9 SAFE (surgically advanced follicular extraction) system,10 and ARTAS Robotic System (Restoration Robotics, Inc, San Jose, CA) are a few of the more well-known FUE devices on the market. In this article, the authors discuss about robotic follicular unit extraction with the robot.
Robotic Follicular Unit Extraction

Technical Aspect
The robotic system was approved by the Food and Drug Administration for hair transplantation in 2011.  This robotic device is used to harvest follicular units from the donor region (Figure 3). A 1-mm punch is attached to the robotic arm consisting of a “needle- within-needle”; there is a sharp inner punch sur- rounded by a blunt outer punch. The sharp inner punch creates a shallow 1-mm incision, subsequently, the blunt outer punch spinning at 400 to 800 rpm dissects deeper and separates the follicular units from surrounding tissue. A suction system attached near the punch elevates the follicular unit from the surrounding skin allowing for easier extraction of the graft. A combination of stereoscopic cameras managed by image processing software allows the sharp and blunt punches to identify the precise angle and direction of hair growth. This continuous imaging feedback allows the robot to precisely harvest each follicular grouping. Because of the high level of automation, the robot is able to remove 400 to 600 grafts per hour.11–13 The software requires a minimum distance of 1.6 mm between extracted follicular groupings to minimize risk of overharvesting donor hair. In Table 1, the authors compare strip harvesting with robotic FUE donor harvesting.

Robotic Hair Transplant Pioneer Introduces Automated Graft Selection

Dr. Robert M. Bernstein, Clinical Professor of Dermatology at Columbia University and founder of Bernstein Medical – Center for Hair Restoration, introduced robotic follicular unit graft selection using the ARTAS® Robotic System at the 2015 ARTAS User Group Meeting in Newport Coast, CA. By automatically selecting follicular units with two or more hairs, the robot can harvest the number of donor hairs needed to achieve the greatest cosmetic benefit in the transplant while creating the least amount of wounding to the scalp.
 


Dr. Bishara’s office locations in Mansfield and Southlake, TX have also added this important step in the Follicular Unit Extraction (FUE) procedure, a step that until now needed to be performed by hand. The goal of the new function is for the robot to automatically obtain the maximum number of donor hairs with the least amount of wounding and the greatest cosmetic benefit for the patient.  Dr. Bishara is the only doctor in Texas that offers Graft Site Selection.
How Does it Work?
Using robotic graft selection, the hair restoration surgeon programs the ARTAS robot to harvest follicular units which contain two or more hairs by selectively skipping over the 1-hair units. Using its advanced optical guidance system, the robot orients itself to the scalp by way of special markings on a tensioner, a plastic frame-like device that is positioned on the donor area. The software then rapidly analyzes each graft and selects the appropriate ones for extraction. It then dissects these follicular units from the surrounding scalp tissue.
The Importance of Graft Selection in FUE
In FUE hair transplant procedures, the surgeon wants to harvest as much donor hair as possible while leaving the fewest number of wounds. To minimize the number of wounds, you would want to extract only the units that contain the largest amount of hair. However, smaller grafts of 1-hair are typically needed to create a natural-looking hairline and temples. By selecting and extracting larger grafts first, and then extracting smaller ones only as needed, surgeons can both minimize wounding and harvest an adequate number of follicular units of varying size so as to enhance the cosmetic benefit of the procedure. Smaller grafts can be generated by dividing the larger grafts without increasing the donor wounding.

A recent survey conducted by the International Society of Hair Restoration Surgery (ISHRS) showed that men and women around the world are seeking to correct hair loss while they’re younger rather than putting it off until later in life.
Since the ISHRS starting tracking data on hair restoration in 2004, the extrapolated worldwide volume of surgical hair restoration procedures performed from 2004 to 2012 increased 85 percent.  What explains this tremendous increase in people seeking help for hair loss, even during tough economic times?  We believe the unprecedented growth and increased popularity in hair restoration over the past decade can be directly attributed to the continual refinements and advances in this type of surgery – together with proven medical therapies – that produce natural-looking, permanent results.
Other key findings of the survey include:

  • The number of women undergoing hair restoration surgery worldwide increased 20 percent from 2004 to 2012
  • Patients aged 30 to 49 sought treatment for hair loss more than any other age group
  • In 2012, ISHRS members chose John Mayer and Sofia Vergara as the celebrities with the best hair

Hair Transplantation
During a hair transplant, hair is redistributed from fuller areas of the head, typically the sides and back of the head, to the balding or thinning areas. These grafts are placed to create a natural appearing result. The new hair follicles act as your normal hair, growing at the same rate as the rest of the area. The procedure can help you achieve a fuller head of hair and the results are permanent.

Like good health and youth, most of us take a thick head of hair for granted — that is, until it is gone. For many people, hair transplant procedures can help bring back the appearance of a full — or at least a fuller — head of hair.

Overview of Robotic Hair Transplant Procedures

Robotic hair transplant surgery is a logical advance in the technology of Follicular Unit Extraction (FUE). The potential advantages of Robotic FUE (R-FUE) over traditional FUE procedures include:

  • Increased accuracy of harvesting grafts to minimize damage to follicles
  • Ability to use FUE in a wider variety of patients
  • Reduced harvesting time
  • Increased graft survival

Follicular Unit Extraction is a harvesting procedure where hair is removed directly from the donor region of the scalp as individual, naturally-occurring groups of 1-4 hairs. The technique consists of two main steps: 1) Separation of the follicular units from the surrounding skin, and 2) Extraction (removal) of the follicular units from the scalp.
Step one, the separation of the follicular units from the surrounding donor tissue, is a highly repetitive and labor intensive process that requires great precision. This step requires the centering of the punch over the follicular unit and the alignment of the dissecting instrument with the follicles to prevent damage. This step, which must be repeated manually hundreds to thousands of times in a typical FUE procedure, subjects the patient to significant human variability and error.
The problem associated with the initial step of separating follicular units from the surrounding tissue has been a major challenge for FUE practitioners. A significant advance towards minimizing trauma to follicular units in this first step was to divide it into two parts; sharp, followed by blunt dissection. This additional step reduces the chance of injury to the lower part of the follicles during dissection. The current robotic system is based on this concept.

 

Risks and Costs of Treatment

 
The cost of hair transplantation will depend largely on the amount of hair to be transplanted, but it generally ranges from $4,000 to $15,000. The procedure is rarely covered by insurance.
As with any surgical procedure, hair transplantation carries risks, including bleeding and infection. Other risks that can occur with hair transplants include scarring and unnatural-looking new hair growth.
Around the time new hair growth starts, some people experience inflammation or infection of the hair follicles, called folliculitis. This can be relieved with antibiotics and compresses. Another potential risk is the sudden loss of transplanted hair, called shock loss. Fortunately, this hair loss is rarely permanent.
If you are bothered by thinning hair or balding, hair transplantation can significantly improve your appearance and self-confidence. However, it is important to understand that hair transplantation is just that — transplantation of hair you already have to a place where it is more visible. It does not create new hair.
To minimize the risks and improve the success of surgery, it is important to undergo hair transplantation only if you are healthy. You should always discuss the potential risks and benefits of any surgery with your doctor.

The ARTAS Robotic System

ARTAS Robot's Imaging System
The ARTAS Robot’s Imaging System

The ARTAS FUE robot is an image-guided system composed of a robotic arm, dual-needle punch mechanism, video imaging system, and a user interface. Its extraction technique consists of a double-punch arrangement with an inner (sharp) punch and outer (dull) punch. The inner punch has cutting capabilities to score the upper most part of the skin and the outer punch has a blunt edge used for dissection of the follicular units from the surrounding tissue that minimizes injury to the grafts. The image-guided system allows this step to be accomplished with great precision. The patient lies on a specially designed operating table that allows access of the robotic arm to the donor area of the scalp.
The ARTAS System is an interactive, computer assisted equipment employing image guidance to enhance the quality of hair follicle harvesting. ARTAS is the first hair transplant robot to improve the most challenging aspects of Follicular Unit Extraction (FUE).
There are two common ways to treat balding including strip harvesting and follicular unit extraction (FUE).  Strip harvesting is the most commonly used technique right now, and it is an efficient means of harvesting large quantities of follicles.
FUE offers less discomfort and a faster return to normal daily activities than traditional, more invasive methods of hair restoration. Performed in Dr. Bishara’s office, FUE with ARTAS moves healthy, functioning follicles to the areas of the patient’s scalp most impacted by baldness for more dramatic results. The implanted hairs develop their own blood supply, begin to grow and new hairs are seen a few months after the procedure has taken place. New hair continues to grow over the course of a full year, making the change in the patient’s appearance gradually noticeable to others. Healing time is short, and there is no resultant linear scar as happens with other methods of hair restoration. The only evidence is tiny, white scars left in the donor area, which are the same as those produced by manual FUE.

Benefits of ARTAS System
Robotic technology is used in numerous surgical and diagnostic procedures to improve the efficacy of treatments.  Restoration Robotics has incorporated robotic technology into FUE resulting in the ARTAS system which is the first and only FDA-cleared technology that allows the physician to control the image-guided robot.  I am able to make minor adjustments to dissection depths and angles during the extraction process ensuring my patients receive optimal results.
