Standardization of the Terminology Used in FUE
Dr. Jean Devroye MD, en collaboration avec le Dr. John P. Cole, le Dr. Bob True et le Dr. Jose Lorenzo
Part I
Anatomy

The definition of the follicular units, according to Headington (1984), is:

“The follicular unit (FU) of the adult human scalp usually consists of two to four terminal follicles and one or
rarely two vellus follicles, the associated sebaceous lobules, and the insertions of the arrector pili muscles
of the terminal follicles. At superficial dermal levels follicular canals may or may not join each other, although
it is common to find two or three hair shafts within a single canal at the level of the infundibulum. The vellus
follicle of the follicular units may remain separate or may be joined to the confluent infundibula of the terminal
follicles.”


Follicular Group, Follicular Family, Follicular Cluster, or Follicular Bundle :

These are defined as clusters of hair in the scalp that exit the skin in close proximity to each other and are
separated by a gap from other clusters of hair. The follicular group may consist of more than one follicular unit in a tightly packed distribution on the surface of the skin. In complex donor areas consisting of multiple large bundles or closely aligned bundles, the number of separate bundles obscures individual interpretation and leads to variable individual assessment

Sub-Follicular Group Graft: This is a graft extracted from a follicular group where a portion of the follicular group remains in the donor area.
CTS : connective tissue sheath
ORS : outer root sheath
IRS : inner root sheath
DP : dermal papilla
Splay : This describes divergence of follicles from one another, typically occurring at the lower one-third of the follicular unit. The degree of splay is widely varied from no splay to substantial splay. Splay may involve one follicle within a group or all follicles within a group.
Anchor System of the Follicular Units : This defines the structures that impede the extraction of the follicular group from the surrounding tissue. The follicular adherence includes the sebaceous gland, and the insertion of the arrector pili muscle, the attachment of the dermis, and the connections between the CTS and the surrounding adipose tissue.
Tethering : This is the term to describe the attachment of the connective tissue sheath and outer root sheath to the surrounding adipose of a follicle. In most individuals, the strength of this attachment is very weak, so we can extract the graft once we cut the superior anchor system, but in others, it is quite strong, requiring more tension during extraction.
Hypopigmentation : This is the name given to the loss of skin color caused by loss of melanin, loss of the hue from individual follicles, and the loss of circulation from the skin surface during the healing process. Following the harvesting process from the scalp or body, the extraction sites often heal by secondary intention. The surface area of hypopigmentation (commonly named white dots) can be extremely variable depending on
different factors, such as skin or hair color, and the tools used for the extraction. Based on experience, hypopigmentation is more common in the inferior part of the donor area of the scalp, chest, and abdomen, and less noticeable on the traditional recipient area of the balding scalp, legs, and beard.

Transection

Capping or Topping : This occurs when, after incising a targeted graft and attempting to remove it with the forceps, we obtain a small cap or top of tissue (epidermis and dermis) with no terminal hair follicles, which remain in the donor site. In most cases, this is due to not having achieved sufficient depth with the punch
to liberate the graft. In other instances, this may occur when sub-optimal force, or when improper forceps
placement is applied to the graft during the extraction process. On occasion, a telogen or vellus hair may be
removed within the cap during this process.
Pluck : This is one or more than one terminal hairs removed by pulling out a follicular group with a forceps with the aim of the removal of viable follicles from the donor area that can be inserted in the recipient area. A pluck could comprise one or more naked follicles devoid of all components of the connective tissue sheath (CTS), outer root sheath (ORS), and inner root sheath (IRS) and dermal papilla (DP), or a fraction of the CTS, ORS, and IRS. In some instances, only the IRS remains. Generally, when the distal portion of the ORS is left in the donor area as a result of a pluck, the DP also remains in the donor area.
Broken or Fractured Follicle(s) : The broken or fractured follicle(s), as opposed to transection, retains both ends of the hair with a separation of a follicle into two, or more, pieces due to stress at some point along the length of the follicle.
Paring or De-Sheathing: These are grafts where the CTS, ORS, and perhaps the IRS are slashed in a longitudinal fashion by the cutting edge of a sharp punch.
Splitting : This is the action of separating with the punch in vivo (or in situ) a portion of the follicles from a group (follicular family or follicular unit). The extracted graft will contain fewer follicles than are in the group. Splitting can be produced deliberately or unintentionally.
Partial Follicular Family Harvesting : This involves the entire process of harvesting (i.e., splitting and then extracting) a fraction of a follicular unit such that one portion of the follicular unit is harvested from the donor area while the other portion of the follicular unit remains in the donor area. It’s also called “vertically split
harvesting” or “vertically cut harvesting.”
Individual Group Harvestin : This involves harvesting an intact group of follicles based upon their proximity and position as they exit the epidermis consisting of one or more than one follicular unit at a time.
Transection : Term used to report any microscopically visible breakage of a follicle anywhere along its entire Transection length. A graft could be a completely transected graft when all of the follicles are cut transversally or a partially transected graft when one or more follicles are cut leaving one or more intact follicle.
External Dissection (Figure 13): This action details how a graft is divided under the microscope into singles or groups containing fewer follicles than the original intact group, for example, to be used in or near the front hairline.
Graft Cleaning : This refers to the removal of the transected part of a follicle from an FUE graft under the microscope.
Trimming : This refers to the removal of the dermis and other undesired perifollicular tissues of an FUE graft under the microscope with the aim of making the graft slimmer. The advantage of trimming is to make a graft fit into a smaller recipient site or to reduce the volume of tissue inserted into recipient sites so that volumetric expansion of the recipient area or ridging is minimized

Different Techniques Employed

Follicular Unit Extraction : The concept of FUE was first published in the tabloid newspaper “The Sun Herald” in Australia on October 15, 1995. It was an advertisement for Dr. Woods & Dr. Campbell’s top-up
microsurgical technique where the donor extraction was done one follicular unit at a time (Figure 14).
In the advertisement, the concept of FUE was actually described as “Hair Follicle Single Unit Extraction,” which accurately depicts the pure idea of the technique: one follicular unit at a time. Drs. Bill Rassman and Bob Bernstein officially described the term FUE in 2002 as “the removal of individual clusters of follicles from
the donor area using a sharp dissecting punch or trephine.” In the original article, the grafts were harvested
using a 1.0mm sharp trephine2.
In strict terminology, the term “follicular unit extraction” is inappropriate and misleading because it is a
histological term rather than an accurate anatomical surgical term. More appropriate would be term FIT
(Follicular Isolation Technique), but the use of FUE has prevailed and the term is too difficult to eradicate
today.
Follicular Isolation Technique : Also known as FIT, Dr. Paul Rose derived this term to more appropriately describe the procedure commonly referred to as FUE in 2002. The term FIT includes the possibility that a graft does not always get all the follicles of a follicular unit or it might include follicles in more than one follicular unit. It is possible that during removal the surgeon may extract, intentionally or not, one or several follicles, leaving behind a viable hair in the donor site. Alternately, the surgeon might extract more than one intact follicular unit. Therefore, the preferred term by the early pioneers in FUE was “follicular isolation” rather than “follicular unit extraction"
Cole Isolation Technique (CIT) : Developed by Dr. John Cole, CIT is a follicular extraction technique that incorporates a variety of highly sharpened, thin wall punches along with a precise depth control mechanism.
The goal of CIT is to minimize the follicle transection rate by varying the punch diameter, limiting depth, modifying punch geometry, and altering tangential forces. The objectives of CIT are to match donor harvesting
methods to the individual physical characteristics of each patient along with overall goals of both short- and long-term patient planning. CIT may involve harvesting a portion of a follicular group or intact follicular groups.
Harris Safe Technique : The method introduced by Dr. James Harris in 2004 is both a manual and mechanical method of graft harvesting. Initially, the method consisted of using a sharp punch to score the dermis of Different Techniques Employed the skin followed by deeper dissection with an unsharpened dull, or blunt, punch developed by Dr. Harris, which he called a two-step method. Following the second step, the graft is removed with a pair of forceps. Subsequently, Dr. Harris attached his unsharpened to a rotating drill. With the mechanical version, the surgeon may perform the procedure in a single step.
Body Hair Transplant : Donor follicles are harvested from any region of the body except the traditional scalp donor area. Body hair includes all hair inferior to and inclusive of the neck and beard. Body hair has an unpredictable and variable yield.
Beard Hair Transplant: Donor follicles are harvested from the beard area on the face and neck of a patient. Beard hair transplants have a higher mean yield than other sources of body hair and a much faster rate of growth than other sources of body hair.
Woods Technique : This is the original term given to Follicular Unit Extraction by Drs. Ray Woods and Angela Campbell. Even though they never published their results or shared their experience with other physicians, they can be considered an essential part in the development of the FUE technique based on their Internet publications.
Fox Test : This refers to a test procedure performed when a physician wants to confirm that a patient is a good candidate for FUE. Drs. Bill Rassman and Bob Bernstein coined the term in their 2002 paper that described the FUE procedure

Motorized and Robotic Devices

Powered Cole Isolation Device (PCID) : This programmable device developed by Dr. John Cole allows for a more precise control of rotation, oscillation (and the duration of both), speed, rate, and arc of oscillation.
Harris Safe System (Figure 16): Developed by Dr. James Harris, this follicular extraction device utilizes an unsharpened, dull, or blunt punch (0.8-1.2mm) with full rotation at variable speeds and a fixed depth stop.
NeoGraft : This is a motorized rotating extraction device utilizing a sharp punch with both negative and positive pressure mounted on a right-angled handpiece. Negative pressure allows the surgeon to suck the
graft into a collection chamber and keep the operating field clear of blood. A deep incision is required to loosen the graft enough to allow the weak suction to remove the graft from the donor site. Grafts may also be removed using a pair of forceps. The grafts can be inserted in the recipient area using positive pressure.
The NeoGraft is similar to the Calvitron, originally conceived by Dr. Pascal Boudjema. The term Omnigraft is
primarily used in Asia for thie device.
True Device : Aseptico Porta-Tip – AEU-03SS and Ossada SH28S handpiece. This is a rechargeable rotary hand engine with variable speed control and autoclavable handpiece that Dr. Robert True uses. He inserts
Cole Instrument Serrounded punches varying in size from 0.8 to 1.25mm. A silicone collar is fitted onto the
punch and adjusted for precise control of incision depth.
Alphagraft : This is another FUE device that uses a rotating sharp punch to harvest follicles from the donor area.
Devroye Device : Developed by Dr. Jean Devroye, this FUE battery powered device uses an oscillating sharp punch controlled by a very sensitive foot pedal. The device allows very short punch oscillation.
Feller Device : Designed by Dr. Alan Feller, this is an oscillating battery powered FUE device with sharp internal diameter cutting edge punches.
ARTAS System : Developed by Restoration Robotics, this robotic FUE device uses a two-step process where a V-shaped sharp punch the skin followed by an unsharpened rotating punch, which penetrates deeper into the tissue to liberate the graft. This is an “automated” system that evaluates follicular unit density, hair angle, and proper depths of sharp and unsharpened punch insertion, based on the physician input data. With that information, the device has the capability to suggest the target units and align the system with the proper direction for dissection. Grafts are harvested while using a tension device developed by Restoration Robotics. The graft is then removed with a pair of forceps.

Standardization of the Terminology Used in FUE

Part II
Characteristics of the Techniques

Rotating Extraction : The punch is rotated a full repetitive 360-degree cycle during penetration of the skin. This is usually done by motor.
Oscillating Extraction: The punch is rotated back and forth through different arcs and repetitions per minute (RPMs) during penetration. This may be done by hand or by a motor.
Rotating and Oscillating Extraction: When rotation followed by oscillation is employed during penetration of the punch. Rotational speed, arc of rotation, ramp (amplitude from starting position to ending position) of rotation, ramp of arc, and duration of each individual cycle may be controlled.
Step Methods: These methods relate the steps that need to be applied, with a punch or other cutting tool, to release the graft from the surrounding tissue. All methods take a last final step common to all the techniques, which is the collection of the follicle with forceps or suction:
-One Step Method uses an extraction punch that is inserted to the desired depth in a single incision using a rotational force, oscillating force, axial force, or combination of rotation and oscillation forces.
-Two Step Method uses a sharp punch to first score the skin using a rotational, oscillating, or axial action. Then either the same sharp punch or a different punch is inserted through the epidermis via the same incision to the desired depth using a rotating or oscillating action. The second punch may be a different sharp punch or a dull punch.
-Three Step Method : uses a sharp punch to score the skin followed by a sharp or unsharpened punch to penetrate as in the two-step method. Then a needle or other sharp device is used to cut the graft free at the base while traction is applied with a forceps to remove the graft.
Sequential Method: The surgeon holds the punch and the forceps in both hands at the same time. The grafts are first cut with the punch in one hand and then removed with the forceps held in the other hand,
one graft at a time and in rapid sequence.
Coring Method: A sharp punch is inserted with a single axial force applied along the axis of hair growth without rotation or oscillation. Following the initial axial force a tangential force may be applied to help
loosen the graft prior to removal with forceps.
Open Method: Also called Lift and Look. The skin is cut using a punch to first score around the graft. Next, the cluster is pulled from the surface of the skin so that the surgeon can see the direction of hair growth and splay. Then a series of maneuvers may be used to dissect down along the follicular unit. The process may be assisted using suction to clear the visual field.
Sharp Dissection : This is when a sharp punch is inserted along the course of the follicle to facilitate its extraction.
Dull Dissection : This is when an unsharpened punch is inserted along the course of the follicle to facilitate its extraction. The dull dissection uses a dull punch with an unsharpened edge that has a wide wall to allow a wedge-like configuration with the aim of separation of the follicles from the surrounding tissue.
Pulling : This is defined as the anterior traction used for the removal of the graft, after it has been punched. Grafts may be pulled with a one-hand pull with a single forceps, a two-hand pull with two forceps, with an ATOE (see below), or with suction.
Scoring : This is a superficial cutting of the epidermis and dermis with a punch, to produce a superficial circumferential or semicircle incision around a follicular grouping.
Depth Control : This refers to the utilization of different accessories on or around the punch to precisely control the depth to which the punch can be inserted.
Limited Depth Extraction : The punch is inserted only to a depth of 1.8-3mm, but typically 2-3mm, in order to release the follicles from the surrounding tissue with the help of forceps. Limited depth extraction
minimizes follicle transection.
Full Depth Extraction : The punch is inserted the full length of the follicle (from 4 to slightly more than 6mm depending on the patient) to meet or exceed the level of the bulbar region of the follicular group and
completely free the follicle(s).
Follicle Distortion : This is the physical movement of the follicle in reaction to the axial and tangential forces resulting from the physical process of follicular unit extraction.
Axial Force : This is the force applied parallel down the centreline of the hair follicles during graft extraction. When the force is evenly distributed, the force is concentric. When the force is unevenly distributed, the force is termed eccentric. Because the inferior margin of the punch touches the skin first due to angle of
hair growth, the force is often greater on the inferior aspect of the tissue during graft removal. This uneven
force often causes follicle displacement.
Tangential Force : This is the force applied through rotation or oscillation of a punch around a follicle or group of follicles.
Donor Tension or Traction : Tension may be applied to the donor area to stabilize the fluidity of the tissue. Tension may be applied by a variety of means including the following: tumescence, clamps, or manual or
stretching forces applied through other means such as tensioners or stapling a latex material from one side
of the scalp to the other.
Bulls Eye : This is when the follicles being extracted within a follicular group are perfectly centered in the punch during its insertion.
ATOE (Aide to Extraction): This is a specialized forceps with specialized design, created to facilitate a rapid extraction of the previously dissected grafts.
Delay in Extraction: This is the temporal difference between the time when the punch incises the grafts using a single step or multiple step process and the time when the grafts are physically removed from the
donor area. Following the delay in extraction, the grafts may be placed in a holding solution or reinserted into the scalp immediately.
Follicle Depth: Defined by the distance from the surface of the skin to the full length of the follicle below the hair bulb.
Time Out of Body: This is the quantity of time between the removal of the graft containing one or more than one follicles from the donor area with forceps or suction and the reinsertion of the graft into the
recipient area. The graft may go into a holding solution first or it may be immediately placed into a recipient
site.

Punch

Handle : The tool by which the punch is held, carried, and depth controlled. There are some different
handles for the manual FUE technique, the most popular are the Versi handle and the CIT manual punch
handle.
Cannula Punch : This is a cylindrical punch usually made of stainless steel.
TiN Coated Punch : This is a punch whose tip is coated with titanium nitride (TiN) so that the punch has a
characteristic gold colored tip. This improves the lifespan of a sharp punch.
Serrated Punch or Wave Punch : This is a punch with a serrated cutting edge that offers many small points of contact with the skin. It can also be called a triple wave punch (Rassman).
Serrounded Punch : This is a very sharp, thin walled punch with serrated tips that reduce the surface area in contact with the skin with the aim to diminish the amount of frictional force (Cole Instruments) diameter in a center bevel punch. Attention should be paid to the specifics of the size of the
punch as different manufacturers vary in their production standards.
Classification of Punch by the Cutting Edge:
-Outside Diameter Punch (or inside bevel punch) has the cutting edge of the bevel located on the external surface of the wall of the punch.
-Middle Diameter Punch (or middle bevel punch) has the cutting edge of the bevel located on the middle of the wall of the punch. The location of the cutting edge is not always EXACTLY in the middle wall of the punch.
- Inside Diameter Punch (or outside bevel punch) has the cutting edge of the bevel located on the inside
face or at the inner part of the wall of the punch.
Classification of Punch by the Diameter of the Cutting Edge:
- Small Punch has a cutting edge diameter that is equal to or less than 0.8mm.
- Medium Punch has a cutting edge diameter that is greater than 0.8mm and less than 1mm.
- Large Punch has a cutting edge diameter that is equal to or greater than 1.0mm.
Classification of Punch by the Sharpness of the Cutting Edge:
-Sharp Punch : has a sharpened cutting edge.
-Dull Punch : has an edge that is not sharpened.
Safe Donor Area : The portion of the scalp that contains follicles presumed to be the permanent hair within the donor area. This presumed permanent “safe donor area” is based on years of experience in
hair restoration by a number of physicians, but it is impossible to accurately define this surface area in all
patients. In some individuals, this surface area may be greater, while in others, it may be less. Furthermore,
there is no guarantee that all follicles within a “safe donor area” are permanent. This is a very difficult area
to define, especially in young patients.
Donor Area Template : This is a template that allows the margins of the presumed safe donor zone and extraction zones to be marked.
Donor Area Regions : This defines the zones of the safe donor area from which grafts should be
extracted:
-Major Donor Regions are within the presumed safe donor zones of the occipital and temporal regions.
-Minor Donor Regions are zones of secondary use and include the nape of the neck and areas located
inferior to the major donor regions. Hair in these regions is less reliably presumed to be in the safe donor zone in patients who do not have extreme degrees of hair loss. Individuals with higher degrees of hair loss will often lose hair in these regions as they age. Often hairs are finer in these regions and contain a higher percentage of hair in the telogen phase.
-Additional Donor Regions include the temporal areas in front of the ears, the supra-auricular areas, and lateral humps.

Standardization of the Terminology Used in FUE

Part III
Introduction

The terms in this part of FUE standard terminology focus on the measurement of quality in extraction. Utilizing these measurements in daily practice allows the practitioner to fully assess the quality of his or her technique.
In order to perform these calculations, the following must be observed, counted, and recorded in all surgeries:
1) the number of punch insertions; 2) all pieces of tissue removed regardless of appearance; 3) the number
of partially and completely transected follicles in all removed tissue; 4) the number of follicles intact and transected per graft, and 5) pre-operative densitometry.

Results

Intact Graft : This graft is comprised of the entire structure of a healthy terminal follicular unit, including intact structures of the infundibulum, isthmus, and bulbar structures, and has not suffered any trauma during the process of extraction.
Partially Transected Graft : Refers to a graft that contains one or more follicles that have been transversally cut, but which still contains intact follicles.
Completely Transected Graft : Refers to the amputation of all the follicles within a graft so that there are no intact follicles in the extracted tissue.
Buried Graft : A graft that is pushed and remains under the skin surface during an attempt to cut and isolate with a circular punch.
Empty Graft : A graft of skin lack¬ing hair follicles resulting from the insertion of a punch into bald skin.
Missing Graft (MG) : Any graft (intact, complete or partial transection, capped, buried, or empty) that cannot be located because it is misplaced during the surgery. It’s the difference between the total number of punch insertions and the total number of grafts available for hair transplant, plus the number of grafts unavailable for transplantation:
MG = total number of punch insertions – (grafts available for HT + graft unavailable for HT).
Total Number of Punch Insertions (or Punch Attempts) : The total of all punch insertions made, whether the insertions yield graft or not.
Total Number of Grafts Available for Transplant : The total number of intact grafts or partially transected grafts available for insertion.
Total Number of Grafts Unavailable for Hair Transplant : The difference between the number of punch insertions and number of grafts available for hair transplant. The sum of miss¬ing, capped, completely
transected, and empty grafts equals the total number of grafts unavailable for hair transplant
Total Number of Grafts Extracted : The number of grafts available for transplant plus the number of grafts unavailable for transplant.
Missing Graft Rate (MGR): The number of missing grafts divided by the number of punch insertions. MGR equals:
Number of missing grafts × 100
Number of punch insertions
Graft Transection Rate (GTR): The result obtained when the number of grafts containing one or more transected follicles is divided by the total number of grafts extracted. GTR equals:
Total number of transected grafts (partially + completely) × 100
Total number of extracted grafts
Completely Transected Graft Rate (Total Transection Rate, TTR):
The result of the total number of grafts completely transected divided by the total number of grafts extracted. TTR equals:
Total number of completely transected grafts × 100
Total number of extracted grafts
Partially Transected Graft Rate (Partial Transection Rate, PTR):
The result obtained by dividing the number of grafts partially transected by the total number of grafts extracted. PTR equals:
Total number of partially transected grafts × 100
Total number of extracted grafts
Follicle Transection Rate (FTR or TR):
The result obtained when the number of transected follicles is divided by the total number of follicles that have been extracted, both intact and transected. FTR equals:
Total number of transected follicles × 100
Total number of extracted follicles (intact + transected)
Calculated Follicles per Graft Expected (CFGE):
The number of intact follicles extracted plus the number of follicles tran¬sected divided by number of grafts available for transplant plus the total number of completely transected grafts. CFGE equals:
Intact follicles + transected follicles extracted × 100
Total number of grafts available for transplant + completely transected grafts
Calculated Follicles per Graft Achieved (CFGA):
The number of intact follicles extracted divided by the
number of extracted grafts available for transplant plus the total number of completely transected grafts. CFGA equals:
Intact follicles × 100
Total number of grafts available for transplant + completely transected grafts
Pared Follicle Rate (CFGA):
The number of follicles pared (or de-sheathed) divided by the total number of follicles (intact and transected) that have been extracted. PFR equals:
Total number pared follicles
Total number of extracted follicles (intact + transected)
Donor’s Area Calculated Density (Hairs per Follicular Group):
The number of follicles counted in the donor area divided by the number of follicular units or follicular families counted in the same donor area (typically performed with a dermatoscope or trichoscope).
