Comparison of Different Instruments to Make Recipient Sites: Needles vs. Blades

August 8th, 2005

SUMMARY of Dr. Perez-Meza’s Abstract from his presentation at the International Society of Hair Restoration Surgery, 2005 – Sidney, Australia

There have been great advances in hair restoration surgery over the past decade. New surgical techniques, instruments and medications have been developed to treat patients with hair loss. Some surgeons use needles to create the recipient sites and others use blades – both groups obtaining great results. There is some controversy, however, about the “ideal” instrument to make the recipient sites.

The objective of this study was to evaluate three different blades and three different needles used to make sites in the recipient area and to compare the wound healing and hair growth after the hair transplan

5 alpha-Reductase Inhibition in Hair Growth

August 8th, 2005

SUMMARY of Dr. Epstein’s Abstract from his presentation at the International Society of Hair Restoration Surgery, 2005 – Sydney, Australia

Dihydrotestosterone (DHT) is known to be the more potent androgen in both Benign Prostatic Hyperplasia (BPH) and in Androgenetic Alopecia (AGA). Testosterone is converted to DHT by the enzyme 5-α reductase in several organs including the prostate, hair follicles, skin, liver and sebaceous glands. 5-α reductase exists in two isoforms: type 1 and type 2. Type 2 is the predominant enzyme in prostate and hair follicles. Finasteride, approved in 1992, inhibits the type 2 isoenzyme, and is available in two doses: 1mg dose for AGA, and 5mg for BPH. Dutasteride, approved in January 2003 to treat BPH, is a dual inhibitor of both isoenzymes.

Follicular Unit Growth at Four Different Hair Transplant Densities

August 8th, 2005

SUMMARY of Dr. Beehner’s Abstract from his presentation at the International Society of Hair Restoration Surgery, 2005 – Sidney, Australia

There is a need to find the “threshold” density at which follicular unit (FU) graft recipient sites may be placed and yield excellent survival following a hair transplant. It also needs to be determined whether or not a smaller recipient site makes a difference in graft survival. This study looks at hair survival in two patients 18 months after they were each transplanted with four different densities.

The objective of the study was to determine the optimal density for “dense packing” FU grafts without causing loss of hair from vascular compromise or other factors that can affect graft growth during hair restoration surgery.

Solution to Decrease Swelling after a Hair Transplant

August 8th, 2005

SUMMARY of Dr. Abbasi’s Abstract from his presentation at the International Society of Hair Restoration Surgery, 2005 – Sidney, Australia

Edema of forehead and peri-orbital area is observed frequently after a hair transplant. To prevent this edema the authors introduced a new method (Abassi’s solution) at the 12th Scientific Meeting of ISHRS in Vancouver, Canada. The present study tries to determine if Abbasi’s solution can have a negative effect on the growth of transplanted grafts following hair restoration surgery.

In this study, the authors examined the effects of Abbasi’s solution on hair growth one year after a hair restoration procedure.

Hair Curvature: An Important Factor for a Natural Looking Hairline

August 1st, 2005

SUMMARY of Dr. Mohmand’s Abstract from his presentation at the International Society of Hair Restoration Surgery, 2005 – Sidney, Australia

The objective of this presentation is to share our experience and observations regarding the importance of the angle of curvature of the hair shaft during the hair transplant for producing a natural looking hairline.

Four important factors were kept in mind while performing the hair transplant regarding the natural looking hairline: 1) Avoidance of a straight line, 2) Keeping a transition zone between the bare forehead and the dense packing, 3) Density, 4) The acute angle of exit from the skin, 5) The angle of curvature of the hair shaft.

In our experience, since incorporating the angle of curvature of the hair shaft, the naturalness of the hairline has improved significantly. This is especially true for the frontal hair rows and the temporal peaks.

How Long After Hair Transplant Can Grafts Fall Out?

July 29th, 2005

Q: How do you know if you have lost any grafts after a hair transplant and how long after the hair transplant can you still lose them? — T.R. Easton, Pennsylvania

A: Each day following the hair restoration, the transplanted grafts become more fixed in the scalp and the hairs in the grafts become more dissociated (loose). At nine days post-op, the grafts are fixed firmly in the scalp – it has essentially become part of the scalp in the new area and can’t be dislodged.

The hair, however, has totally separated from the follicle by this time, so that it can easily be pulled out without dislodging the remainder of the follicle that contains the growth center. When this hair is pulled out (or is naturally shed) one often sees a tiny bulb at the end. This is the root sheath of the hair and not the growth center. This is normal and is not a lost graft.

If a graft is lost, an event that may occur within the first 3-4 days following surgery, it is almost invariably associated with a small amount of bleeding.

Dr. Bernstein Is Lead Author Of Follicular Unit Transplantation Article In ‘Dermatologic Clinics’

July 28th, 2005

“Dermatologic Clinics” is a hard-cover quarterly peer review publication with comprehensive, state-of-the-art information by experts in the field of dermatology. In a 2005 issue entitled “Advanced Cosmetic Surgery”, Dr. Bernstein is lead author of the article: “Follicular Unit Transplantation: 2005.”

This valuable contribution to the field of surgical hair restoration explores techniques and best practices of the surgical procedure known as Follicular Unit Transplantation that Dr. Bernstein pioneered and is now considered the state-of-the-art in hair transplant surgery.

Trichophytic Closure: A New Way to Camouflage a Hair Transplant Incision

July 27th, 2005

Summary of “Trichophytic Closure of the Donor Area” which appeared in Hair Transplant Forum International July/August 2005 by Mario Marzola, MBBS Norwood Australia

When hair transplant surgeons meticulously close the edges of a donor wound, they generally end up with a fine, linear scar that is approximately 1-2mm in width. Sometimes, the scar can be a bit wider and every once in a while, when the person’s connective tissue is weak, or the edges of the scar are closed too roughly or have too much tension, the scar can be a cosmetic problem. The educated patient, who has expectations of a thin scar, or the patient who is likely to wear his hair very short, hopes that their hair transplant doctor can produce scars that are practically invisible.

A Trichophytic closure is a way of improving the linear donor scars of hair transplant patients. A Trichophytic incision in hair transplantation involves trimming off the upper edge of the incision and then closing the wound in such a way the hair near the edge can grow through the scar. This has the potential to produce a scar that is virtually undetectable.

To perform a comparison study, Dr. Marzola conducted a trial using 26 consecutive patients. Each hair transplant patient had one side of their scar closed trichophytically (i.e., with the top edge removed) and the other side closed with the edge left as is.

In an FUT Hair Transplant, What Percentage of Telogen Phase Follicles in Donor Strip are Wasted?

July 14th, 2005

Q: When a donor strip is taken out during a hair transplant and separated under the microscope, you can read on the internet that there is a wastage of grafts (about 15%), because of those unseen telogen hairs. What do you think about that and how does it affect the hair restoration? — T.B. Baldwin, New York

A: The Telogen phase of the hair cycle is about 3 months long and about 12% of follicles are in this phase at any one time. It is speculated that the follicles may be empty for perhaps 1/2 that time (this number may vary significantly between people). Therefore, approximately 6% of the hair follicles may be in telogen at any one time.

Can a Hair Transplant Restore Original Hair Fullness?

July 5th, 2005

Q: Can you get your original density back with a hair transplant? — C.C. Scarsdale, New York

A: Although the cosmetic benefit can be dramatic, a hair transplant only “moves” rather than creates new hair. In surgical hair restoration, a limited amount of hair from the donor area is transplanted to a much larger area in the front and top of the scalp, so that we can never reach the original density.
