Bernstein Medical Center for Hair Restoration - Pre-Making Recipient Sites

Pre-Making Recipient Sites

About Header Image

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.

Recipient Site Creation at Bernstein MedicalDr. Bernstein creating recipient sites using the ARTAS robot

Hair transplant pioneer Dr. Robert M. Bernstein and his colleague Dr. William R. Rassman have received a patent on a new method that improves the outcome of Follicular Unit Extraction (FUE) — the type of procedure used in half of all hair transplants performed world-wide. The key invention is the addition of a delay between the creation of recipient sites and the insertion of follicular units into those sites. The delay allows the healing process to commence before grafts are inserted, resulting in increased success of the transplant and an improved outcome.

Dr. Bernstein introduced the concept of “pre-making recipient sites” into medical literature in a 2012 publication in Hair Transplant Forum International, has discussed the idea extensively, and presented findings at the 2015 ISHRS Annual Scientific Meeting. However, this is the first time he has patented a hair restoration technique.

The first 24 hours after any wound to the skin is a critical period of time in the healing process. Dr. Bernstein describes this initial period in his 2012 publication:

During the first 24 hours following recipient wound creation, a flurry of biologic activities take place that facilitate healing. These include: the migration of platelets with subsequent release of cytokines, growth factors and pro-inflammatory proteins (histamine, serotonin, kinins, prostaglandins, etc.) that increase blood vessel permeability and stimulate cell migration. Allowing these processes to begin before implantation of the grafts should be beneficial to their healing and subsequent growth. ((Bernstein RM, Rassman WR. Pre-making recipient sites to increase graft survival in manual and robotic FUE procedures. Hair Transplant Forum Intl. 2012; 22(4): 128-130.))

By making recipient sites in advance of harvesting the grafts, three important things are achieved by the surgeon:

  1. The time in which follicular unit grafts are outside the body is decreased
  2. The placement of grafts is facilitated, making it less likely that they are injured in the insertion process
  3. The early phases of the healing process (e.g., blood clot formation, creation of new blood vessels) naturally complete, resulting in a more stable, “fertile” site supplied with oxygen and nutrients essential for graft survival.

Dr. Bernstein proposed “pre-making” recipient sites in 2012 as a way to improve the Follicular Unit Extraction (FUE) procedure, and robotic-assisted FUE (Robotic FUE) in particular. This is due to the fact that the positioning of the patient makes it problematic to create recipient sites and place grafts while follicular units are being extracted from the donor area. This is not the case in Follicular Unit Transplant (FUT) procedures, in which a donor strip is removed from the patient then dissected on a dissecting table. In FUT, recipient sites can be created and grafts can be placed concurrently with the dissection process.

“Pre-making” recipient sites is a protocol that should be followed during all FUE hair transplant procedures. It is also applicable in hair multiplication and hair regeneration techniques that are being studied as a way to provide an unlimited amount of donor hair for hair restoration purposes.

Dr. Bernstein at ISHRS 2015 Annual Scientific MeetingDr. Bernstein at the 2015 ISHRS Annual Scientific Meeting

Small, simple modifications in the sequence of the major steps in a Follicular Unit Extraction (FUE) hair transplant procedure will be beneficial to healing and growth following the procedure, says renowned hair restoration surgeon Dr. Robert M. Bernstein. Presenting at the 23rd Annual Scientific Meeting of the International Society of Hair Restoration Surgery (ISHRS) in Chicago, Illinois, Dr. Bernstein detailed how making recipient site incisions before harvesting follicular unit grafts can improve the outcome of an FUE procedure.

For years, it was standard operating procedure in an FUE hair transplant to first harvest follicular units, then create recipient sites in the balding areas and place the extracted units into these sites. This practice persisted despite the fact that hair restoration physicians had known for years that prolonged periods of time outside the body decreased survival of follicular unit grafts. With the widespread adoption of FUE, and the long time needed for the extraction phase of the procedure, Dr. Bernstein looked for ways to streamline the process.

By making the requisite number of recipient sites before harvesting, the grafts can be placed as soon as they are extracted. This reduces the critical period of time that grafts are out of the body. Sites created before harvesting have more time to begin healing, and so they exhibit less bleeding. This results in fewer grafts that “pop” out of the recipient site during placement. Mechanical trauma to grafts that need re-positioning after popping is also reduced. Allowing time for recipient sites to begin healing might also provide a more fertile bed for newly implanted grafts to take root. Additionally, pre-making sites provides time for crusts to form on the surface of the wound. Removing these crusts before placement decreases post-operative inflammation and promotes wound healing.

Dr. Bernstein proposed that in some large FUE sessions, in which large numbers of follicular units are transplanted, the surgeon might deliberately delay extraction to allow pre-made recipient sites additional time to heal by creating recipient sites the day before harvesting.

In sum, Dr. Bernstein provided the audience of hair restoration surgeons with a practical modification of the traditional FUE procedure that could impact the outcome of every hair transplant. Given the growth in the number of FUE hair transplants being performed (now about 50% of all hair transplant procedures) and the international platform provided by the ISHRS Annual Scientific Meeting, this small procedural adjustment could have a significant benefit for thousands of hair restoration patients around the world.

Q: I understand that in robotic hair transplantation, a robot performs the extraction part of the FUE procedure. What’s the outlook on the robot doing more of the hair transplant procedure? — B.B., Greenwich, CT

A: Currently, the ARTAS® Robotic System is a technology for extracting grafts. This is the most difficult part of a follicular unit extraction procedure, but it is only one part.

There are two other major parts to the FUE procedure: one part is the creation of recipient sites (in our practice, we create the recipient sites first, so that once we harvest the grafts, we can immediately place them into the scalp), and the other part is graft placement.

Recipient site creation involves more than merely making holes in the recipient area. It involves making decisions on hairline design, graft distribution, hair direction, recipient site size and depth. When done manually, the surgeon first designs the new hairline so that the hair transplant will look as natural as possible, particularly as the person ages. Next, the surgeon will demarcate the extent of the area to be transplanted and decide on the graft distribution (i.e., how much hair will be placed in each part of the scalp) and will then prepare a “recipient site” in the part of the scalp that has lost hair. The surgeon will then manually create incisions in the recipient site into which the follicular units will be placed.

On February 8, 2014, Dr. Bernstein unveiled “recipient site” creation capabilities of the hair transplant robot. These new capabilities allow the doctor to import a hairline design and other markings that have been made on the patient’s scalp directly into the robot. The robot then maps the design onto a precise 3-D model of the patient’s head. The physician can then program the proper distribution, direction and depth of the future recipient sites and the robot then creates the sites according to the physician’s specifications.

Graft placement, the last step, is perhaps the most challenging to automate. Engineers are currently working to design and build the capacity to automate the placement of extracted follicular units into recipient site incisions. Done manually, it requires significant hand-eye coordination and a very slow learning curve. For the hair transplant robot, it will be a significant challenge with development taking several years or more.

New York, NY (PRWEB) — Robert M. Bernstein, M.D., F.A.A.D., A.B.H.R.S., founder of Bernstein Medical – Center for Hair Restoration, introduced new technology that allows the ARTAS Robotic System to accomplish a critical step in hair transplant surgery, the creation of recipient sites. Presenting at the 2nd ARTAS User Group Meeting, Dr. Bernstein previewed the recipient site creation technology that brings the robotic system one step closer to performing critical aspects of the labor-intensive, hair transplant procedure.

The ARTAS System is currently able to harvest intact follicular unit grafts from the permanent area in back of one’s scalp using precise robotic technology. This is the most difficult aspect of a follicular unit extraction hair transplant – the newer type of hair restoration procedure that avoids a linear scar in the back of the scalp. Now that site creation can also be done robotically, only one step remains – graft placement.

The ARTAS Robotic System maps the surgeon's hairline design onto a 3-D model of the patient's headThe ARTAS Robotic System maps the surgeon’s hairline design onto a 3-D model of the patient’s head

For the recipient site creation, the doctor first draws a hairline and other markings directly onto the patient’s scalp to delineate the surgical plan. Next, multiple photographs are taken and fed into software, called the ARTAS™ Hair Studio, which converts the images into a 3-D model of the actual patient. This computer model can be manipulated and saved for the patient’s procedure. Using the ARTAS™ Hair Studio software, the physician then specifies the angle, direction, density, and randomness of the recipient site incisions to create the most natural look. During the procedure, the robot uses image-guided technology to avoid existing hairs while it creates up to 1,500 recipient sites per hour. In performing recipient site creation, the robot automates a process that can be physically demanding and prone to human error.

On the advancement, Dr. Bernstein said:

“This development is a crucial step towards a robotic system that can perform every aspect of a hair transplant. A great deal of credit goes to the engineers of Restoration Robotics who have worked to make automated recipient site creation a reality. I am proud that this work not only improves hair transplants for patients, but adds to the increasingly important trend of using robotic technology in medicine.”

The site creation technology that Dr. Bernstein debuted at the ARTAS User Group Meeting; which was held in California (Laguna Niguel, CA) on February 7th and 8th, 2014; will be available to hair restoration physicians in the fall of 2014. Gabe Zingeratti Ph.D, head of R&D at Restoration Robotics, Inc., presented details of the technology, which was beta-tested at Bernstein Medical – Center for Hair Restoration. With the next generation ARTAS® Robotic System rolling out in the coming months, the focus of research will then be on the final phase of robotic hair transplantation, the robotic insertion of follicular unit grafts into recipient sites. This last step will take several more years to develop.

The ARTAS Robotic System, developed by Restoration Robotics, is currently in use by hair restoration physicians around the world to automate the extraction of grafts of skin and hair called follicular units.. Follicular units, which are natural groupings of one to four hair follicles, form the biological basis of the modern hair transplant procedure. Once extracted from the back of the patient’s scalp, the follicular unit grafts are then inserted into recipient sites in the balding area of the scalp where they grow hairs that are immune to the effects of common hair loss.

No stranger to innovative advances in hair transplant surgery, Dr. Bernstein introduced Follicular Unit Transplantation (FUT) to medical literature in a 1995 publication. FUT transformed hair transplants from the use of large grafts of skin and hair, known colloquially as “hair plugs,” to a more medically-oriented procedure that produces completely natural-appearing results. Dr. Bernstein with his colleague Dr. Bill Rassman again broke new ground with his 2002 publication that introduced the concept of Follicular Unit Extraction (FUE) to scientific literature. Dr. Bernstein was the first physician on the East Coast of the United Sates, and one of the first in the world, to use the ARTAS System to perform FUE using the new robotic technology.

Dr. Bernstein Presenting ‘Follicular Unit Extraction: Then and Now’

Dr. Bernstein was honored to deliver the keynote address at the ARTAS International Users Forum in San Francisco, California. Dr. Bernstein’s presentation, “Follicular Unit Extraction: Then and Now,” was a review of the evolution of surgical hair restoration from Follicular Unit Transplantation (FUT) through Follicular Unit Extraction (FUE) to the cutting edge technique of Robotic-FUE.

The presentation described the steps that resulted in the use, and growth in popularity, of the state-of-the-art ARTAS Robotic System for FUE. Dr. Bernstein pointed out that with the introduction of each procedure — FUT, FUE, and Robotic-FUE — there was initially a rocky reception with physicians. In each instance, however, the surgeons’ concerns were overcome first by strong, patient interest and then by clinical studies that confirmed the procedures’ usefulness.

Dr. Bernstein discussed how FUE procedures progressed from the use of hand-held instruments to the computer-assisted, image-guided ARTAS Robot. One of the initial hurdles of FUE procedures using hand-held devices was a high rate of follicular unit transection (cutting of the follicles). Restoration Robotics, Inc., the company that developed the ARTAS system, used a “sharp/blunt” punch technique that was introduced by Jim Harris in his 2004 publication on the SAFE System for FUE. The sharp/blunt technique, that was validated in 2006 by Dr. Bernstein’s research publication, “New Instrumentation for Three-Step Follicular Unit Extraction,” reduced transection of follicles when compared to older instrumentation. Dr. Bernstein then detailed modifications to the system that he proposed in order to improve the ARTAS robot. These improvements include: a smaller tip for the sharp/blunt punch, selection of larger over smaller follicular units, tensioner placement, ‘feathering’ the ends of the tensioner, and pre-making recipient sites before extracting the follicular unit grafts.

Looking to the future, Dr. Bernstein mapped out the further evolution of the Robotic FUE procedure and the tasks it will be required to perform. In future procedures, the physician will not only guide the robot on extracting follicular units, but also in creating recipient sites and, further down the road, placing grafts into the recipient sites. Graft placement will represent the most significant challenge to the robotic system as this step is the most sensitive to patient to patient variability. Once this last step is accomplished, a fully automated hair transplant should be possible, eliminating much of the human error in the mechanical aspects of the hair restoration process.

Program biography on Dr. Bernstein

Robert M. Bernstein, M.D., F.A.A.D., A.B.H.R.S., Clinical Professor of Dermatology, Columbia University, is an early adopter of the ARTAS System for Robotic-FUE. Bernstein Medical, PC, serves as a beta-site to study new product features and enhancements. Dr. Bernstein’s contributions and expertise have materialized in making the ARTAS System more user friendly, improving the harvesting technique and making the ARTAS procedure more compelling for patients at this early stage of commercialization of the product. Pre-Making Recipient Sites to Increase Graft Survival in Manual and Robotic FUE Procedures, has been submitted for publication.

Dr. Bernstein’s comments on roundtable discussion

One of the most important new advances in hair transplantation is Robotic Follicular Unit Extraction (R-FUE). I have been using the new ARTAS Robot, manufactured by Restoration Robotics, for almost a year now. It has made FUE a more exacting and reliable procedure. The “Coffee with the Experts” session that I gave on the topic of Robotic FUE at the ISHRS was standing room only, attesting to the great interest that members of our society have in this new technology.

The theoretical advantage of using a robot to minimize human error in a very repetitive procedure was acknowledged by most members of the discussion group. The ARTAS system has the advantage of using a combination of sharp punch and blunt dissection, a model that was based on Dr. Jim Harris’ SAFE System and one that we have found to work best with the hand-held devices. It also allows us to remove grafts with forceps, rather than by suction. This feature is important since strong suction used to remove the grafts can be more damaging than mechanical removal with forceps.

Its dissection technique uses two punches which are concentrically arranged – a small diameter, sharp bi-beveled punch is nested within an outer, dull punch. The inner punch has a cutting end to score the upper most part of the skin and the outer punch has a blunt edge that dissects the follicular units from the surrounding tissue. We have also found that grafts harvested with Robotic FUE showed less transection compared to other devices that we have used and contained more of the surrounding protective tissue, so it is assumed that this will lead to improved graft survival, but this has not yet been proven.

We find that the robot is more versatile in its ability to harvest grafts from patients with different hair characteristics and from different parts of the scalp. Although there is still variability in the ease of extraction among patients of different racial backgrounds, in our experience, the differences are less when compared to a hand-held system. Also, with the robotic system it seems easier to extract grafts from the sides of the scalp where the hair lies flatter on the skin.

In our practice, we are now able to comfortably extract 2,000 grafts in one day and over 2,500 grafts in two consecutive days. Some of the doctors at the discussion claimed to be able to consistently extract far greater numbers in a single session using manual methods, but it is hard to compare speed without comparing graft quality and transection rates.

One of the exciting things about the new device is that it is continuously evolving. As a beta-site studying new enhancements and features, we have seen all the nuanced changes that continually improve the technique. The initial version of the robot required many intra-operative adjustments to depth, angulation, and the speed of punch rotation, so there were a number of adjustments to monitor. The current system needs far less human intervention than with earlier versions and is simpler to operate, but significant experience is still needed to get the best results. Of course, all the other issues of a hair transplant including; planning, design, site creation, atraumatic graft insertion, etc. persist.

One of my special interests had been to offer patients Robotic FUE with a smaller punch size. We have been working with a 0.9mm punch (the standard is 1.0mm) and have found that this shortens healing time, decreases donor scarring and increases the number of follicular units that can safely be harvested in a specific area. It also creates grafts that require less trimming. On the other side of the coin, some patients, especially African-Americans have less transection with the larger punch, so it is important to be able to customize the technique to the particular person.

Another important modification of the technique that we have implemented since the introduction of the ARTAS system, but that is also applicable to FUE in general, is pre-making recipient sites. This is done either prior to extraction in a one-day procedure or at the beginning of the first day in a two-day procedure. With this change, as soon as the grafts are harvested, they can be placed immediately into the recipient scalp. Not only does this minimize the time that grafts are outside the body, but; by allowing the healing process to begin in the recipient area; it minimizes popping, increases visibility when placing (due to less bleeding), and may create a better environment in which the newly transplanted grafts can grow.

Some of the concerns that doctors had were the relatively high start-up cost in purchasing the robot, the amount of set-up time at the beginning of each procedure and the need, at present, to use two ORs – one for robotic harvesting and one for placing. At present, the patient can only lie on the robotic device face-down. While this position is necessary for the robotic arm to have full access to the donor area, it does not allow easy access to the front or top of the scalp. As a result, graft placement must be performed using a separate operating chair, necessitating the use of two operating rooms for one patient. It is anticipated that within a year, the robotic operating table will be re-designed so that harvesting and placing can be performed in the same room.

Besides some set-up time, one of the things that slows down the robotic process is the tensioner mechanism used to stretch the scalp. Although this feature has the advantage of decreasing damage to follicles, it must be moved every 100 to 150 grafts. With a larger and easier to use tensioner already designed, the delay from its re-positioning should be significantly decreased.

Another concern expressed was that the robot harvests grafts in a somewhat geometric pattern. With experience, one is able to overlap grids and feather the edges so that this appearance, even if temporary, is minimized. New software is planned which can do this automatically.

At the time of the meeting, there were twelve centers in the United States offering Robotic FUE with additional practices in the queue. There was also a strong interest in Robotic FUE among physicians outside the US, particularly in South Korea, Taiwan and Japan.

New York, NY (PRWEB) — Robert M. Bernstein, M.D., F.A.A.D., A.B.H.R.S., a world-renowned hair transplant surgeon, presented a series of improvements to hair transplant procedures which use the ARTAS Robotic System for Follicular Unit Extraction (FUE). These updates include revisions to the FUE surgical protocol and technical adjustments to the robotic extraction system. He presented his refinements at the first user meeting held by the developers of the system; Restoration Robotics, Inc.; on September 14 – 16 in Denver, Colorado.

Dr. Bernstein described his series of improvements in a lecture to an elite group of physicians who are among the first adopters in the industry of the image-guided, robotic-assisted system. The updates are designed to improve the results of FUE hair transplantation by enhancing both the surgical protocols of the procedure as well as the functionality of the robotic system. In FUE, small groups of one to four hairs, called follicular units, are extracted individually from the back and sides of the scalp and are then implanted into recipient sites, which are tiny holes that the surgeon creates in a balding area of the scalp.

The most important update to the FUE procedure that Dr. Bernstein proposed is for surgeons to create recipient sites before they extract the grafts, rather than create the sites after grafts are extracted. Drawing on his decades of experience in hair transplantation, Dr. Bernstein developed this technique of “pre-making” recipient sites in order to maximize survival of the grafts during the hair transplant. Using this technique, extracted grafts are outside the body for a shorter duration of time. It also minimizes instances of “popping,” in which grafts are exposed to desiccation (drying) and hypoxia (low oxygen) before they are inserted back into the scalp. By “pre-making” the recipient sites, these harmful factors are mitigated and a greater number of the grafts grow into viable, hair-producing follicular units. Dr. Bernstein encourages surgeons to use this technique on all FUE procedures, whether using manual methods or robotic instrumentation.

When asked to comment on his improvements to the robotic FUE procedure, Dr. Bernstein said:

“It was fortuitous timing that the ARTAS Robot became available just as I was developing my refinements to the FUE procedure. The combination of the automated robot for graft extraction with the technique of pre-making recipient sites has led to a significant improvement in hair transplant surgery.”

Dr. Bernstein is the founder of Bernstein Medical – Center for Hair Restoration, and he is recognized world-wide for his innovative work in the treatment of hair loss. He is among the first hair transplant surgeons in North America to utilize the ARTAS Robot for FUE in his practice.

Being an early adopter of the advanced follicular unit extraction system has enabled him to work with Restoration Robotics to refine it to his exacting standards. Dr. Bernstein has, again, put his fingerprints on a revolutionary upgrade to the hair transplantation industry. He was the first to describe FUT and FUE procedures in the medical literature, in 1995 and 2002 respectively. In contrast to FUE, where follicular units are extracted individually, in FUT procedures a strip of skin is removed from the back of the scalp, it is then dissected into follicular units, and those follicular unit grafts are then implanted into recipient sites in the patient’s scalp.

Q: While I was lying awake last night your approach of making sites the day before implantation came to mind. It takes guts to have spearheaded that! I am not aware that that precedent has been set in hair transplant surgery. I would have been timid about infection; it’s a lot like closing a wound with a foreign body in it the next day. As with most things, I am a little slow to jump on board something new so I’m glad you’ve paved the way. Do you have any hesitance about this or do you have enough experience that you no longer hesitate? I would be concerned that variations of the local flora might make a difference and that, accordingly, a large sample size would be necessary to get comfortable. Glad for all of us that you are still blazing trails. — S.S., Shanghai, China

A: Thanks for your kind words. No hesitancy whatsoever. We find no increased risk. Think of it as if you did a hair transplant and ran out of grafts. The remaining sites don’t get infected, they just close up. In the process, all those chemotactic factors involved in the healing process move toward the wounds, so if a graft is placed into them, they would be less likely to get infected than a graft placed into a fresh (non-primed) wound, not more. It is like applying the surgical dressing Duoderm to a wound that helps it auto-sterilize. Putting the speculative science aside, we have not seen one single issue with it. Give it a try with an FUE or FUT procedure. Make the sites, have the patient takes his normal shower that night and you will be pleasantly surprised how little bleeding there is the next day and how easy it is to place the grafts.

Robotic FUE has improved Follicular Unit Extraction by automating what has been a labor intensive and often inexact manual procedure. It is the latest in a long line of improvements made to hair restoration procedures that lead to better results for hair transplant patients. Dr. Bernstein’s recent publication in Hair Transplant Forum International improves the FUE procedure even further, whether performing follicular unit extraction with the FUE robot or by hand.

In his article, Dr. Bernstein suggests two techniques to enhance the FUE procedure. First, he recommends that surgeons create recipient sites prior to extraction, in order to decrease the time grafts are in their holding solution outside the body. Second, he suggests adding time between site creation and graft harvesting and placement, to allow recipient site healing to progress.

Pre-Making Recipient Sites

As is discussed in the full article (which is available for viewing and download in our Medical Publications section), by making recipient sites first, the time grafts are out of the body will be reduced.FUE procedures lend themselves to easily reversing the normal hair transplant sequence of graft (strip) harvesting followed by dissection and site creation.

These “pre-made” recipient sites will also exhibit less bleeding than newly created sites and will exhibit the stickiness that makes older sites easier to place grafts into with less popping (a common source of graft injury). Besides allowing the placing step to proceed more quickly, pre-making sites will reduce the risk of mechanical injury inherent in repositioning elevated grafts.

After Site Creation, Add Delay between Graft Harvesting and Placement

While Dr. Bernstein acknowledges the expediency for the hair restoration physician, as well as the comfort of the patient in a single-day session, he suggests that, to facilitate growth after a transplant, multiple-day procedures should be considered in large hair transplant sessions that involve the placement of thousands of grafts.

In conclusion, these two modifications -— pre-making recipient sites and adding a delay before graft placement -— to the FUE procedure can potentially contribute to better growth due to easier, less traumatic graft insertion, a shortened time “out of body,” and the creation of a more fertile bed for the implanted grafts.
