Talk to me about the
pattern of hair loss right there.
ROBERT V. CATTANI, MD: Here
you see typical male hair loss, and we're pointing there to the
frontal scalp. You can see the forehead lines of this young man. His
hair's thinned out and it's receded, and he's
probably, in that frontal area, lost 80-90% of the hairs compared to what
he started off with. He's also a little thin on the top but he
still has pretty adequate coverage up there. So he really needs work done
on the front.
DAVID R. MARKS, MD: Of course, you have to have
donor hair. How do you decide where to get the hair from?
V. CATTANI, MD: Basically we have two types of hair on our head. I
don't want to be overly technical here. But the hair that we have
around the sides and the back is called terminal hair. It grows five to
seven inches a year, each and every year of our life and for the rest of
our lives. Basically. This is simplification. It is concentrated. Each
shaft of the hair is thick. This is the donor hair. So when we harvest
this donor hair and we transplant it, if you will, to the new balding
site, that hair acts like it's never left the donor spot. So
therefore it is permanent, it will prevail for a lifetime and will have
concentration and density, certainly higher than what the balding area has
right now. Never to the extent that the donor hair was. In other words, we
can't make it as thick as where from whence it came.
DAVID R. MARKS, MD: We have picture of harvesting that they're
running right now. So this is really in the back of the head.
ROBERT V. CATTANI, MD: That's correct.
DAVID R. MARKS,
MD: What do you do? You clear out a strip of hair?
CATTANI, MD: Yes. Let me just say this. First of all this is done in a
doctor's office or surgical suite. It is not painful. It is
monitored. We give the patients novocaine-type substances. Then by the use
of a surgical blade we will remove a certain segment of the scalp.
DAVID R. MARKS, MD: Is that what's outlined there, the
strip that will be removed?
ROBERT V. CATTANI, MD: Yes, it is.
From this harvesting we'll be able to create several hundreds of
grafts. Thousands of hairs sometimes. I think it's safe to say,
and I want Dr. Reed to give comment on this. I like to move approximately
2,000 hairs per procedure. Dr. Reed would like to comment on that
MICHAEL L. REED, MD: Yes, I think the new
definition of what's called a megasession, which is the largest
session that can be safely be done to make a lot of progress in just one
procedure, is to move somewhere between 2,000-3,000 hairs, which, in the
follicular unit world is anywhere from maybe 1,000-1,200 follicular units,
which are these clusterings containing two or three hairs per unit. We
take out the strip of tissue and under a dissecting microscope,
it's first microdissected into little tiny slivers which are a few
millimeters thick and then it's subsequently dissected into
smaller grafts containing anywhere from one, or maybe two or maybe three
follicular units at the most. So anywhere from one to maybe eight hairs
per graft. Then those grafts are put very closely together in surgically
produced sites in the new home, in the recipient site, in a pattern that
resembles that found in mother nature.
DAVID R. MARKS, MD:
We're going to look at that in a minute. But it looks like a very
large strip that's taken out. How is the healing? Is there any
MICHAEL L. REED, MD: Any time that there's
surgery there can be a scar.
