FUE Technique is sufficiently advanced now so that to avoid less trauma
to not only the follicular unit to be extracted but also to the follicles around
that. The strip method in fact while cutting out the strip and then
while making the slivers and then cutting the individual grafts from the
slivers can damage more number of grafts than done by individual follicular
extraction.
1. When follicular units are extracted the cut is only made till the level
of sebaceous glands and the part of the follicle below that level which
is harboring stem cells and is important for the growth is not touched
with knife by the techniques that we use so not only the follicle to be
extracted but follicles around that are not damaged. 2.The lower part of
the follicle is any way loosely attached to the surrounding and easily
come out without cutting. 3. More over we use tumescence ( inflate tissue with saline)
this separates the follicular units from one another so that while
extracting one the other does not come in the way. 4. We use
smaller punches with 0.75 to 1mm diameter which which avoids the lateral
trauma to the surrounding follicles check the attachment.
There are 2 methods of Hair Transplant as per the latest
evidences following are our views:
1. FUHT or Strip
method ( a conventional method that requires stitches at the back and leaves a permanent linear
scar which at the back that does not make it possible to wear a short hair
style and sometimes gives pain and numbness for a few weeks to few months.
Healing time is longer due to a long cut at the back)
2. FUE (With
recent advances this modern and stitch less method that does not leave a linear
scar on the back of the head and heals faster and practically pain free post
operatively. Final outcome is better). We use 0.75 to 1 mm micro punch with
depth control and use Lorenzo technique for extraction.
The difference between
the 2 methods is essentially in harvesting the roots from the back side of the
head and the method of grafting and the final outcome of both methods in the
area of hair loss (recipient area) is the same. We now
strongly believe that FUE is except for the cost is superior method than the
FUT (Strip method).
Shock Loss ,
Reactive Loss or Telogen effluvium, Shock fall out: It is reaction to the surgery esp. that on the scalp because
the scalp is stressed by surgery and some of the hairs may fall out in 2 to 12
weeks some are permanent and some can be temporary. Most likely the
miniaturized hairs are likely to fall out. This can happen mostly in recipient area but
can rarely also happen in the donor area esp. in the FUT or strip method and
less commonly in FUE method due to its minimally invasive nature. The Shock
loss is unpredictable although factors to be considered are: Age: young ( <30) more with active inadequate stabilization of hair loss
it is common but in Older age patients with stabilized hair loss has les
chances of shock loss. Sex: male more common than female but it is more significantly visible in
females Male more
likely to be permanent in female more likely to regrow Miniaturized hairs (i.e. the hair that is at the end of its lifespan due to genetic
balding): more likely to be permanently lost unless Finasteride supported Terminal Hairs ( Healthy) : more likely to grow back in 4-6 months Transplanted hairs: shock loss is less common but can grow back in 4-6 months Temporary Loss: The terminal or healthy hair shock fall out is usually tempoaray and
they grow back by 4-6 m9onths Permanent loss: usually of the miniaturized hairs or of the terminal hairs that is
damaged or transected while making the incision for grafting in between the
hairs. Protection: by starting Finassteride 1mg ( or Dutaseride 0.5mg) per day at least 2
weeks before until the at least 6 months post op in males. In females
Finasteride is useless and Minoxidil may be useful to some extent. How can one minimize
Shock loss:
1by using smaller incisions for
recipient area ( using smaller grafts rather than using minigrafts)
2Limiting the depth of incisions
1.Minimizing the adrenaline use in recipient
area
2.Reducing the packing between the
existing hairs
3.Minimizing the tension of the donor
area
4.Using Finasteride from at least 2
weeks before the procedure and for 6 months after the procedure.
5.Spacing the 2 sessions of transplant
at least 1 year apart
6.Avoid operating on the young patients
who are in the actively losing state and have high miniaturization. Put them on
Finasteride & or Minoxidil for a few months before contemplating transplant.
7.Plan to use enough FU and transplant
through the highly miniaturized hairs rather than avoiding that area so that in
case of shock loss of highly miniaturized hairs the area is sufficiently
compensated with the healthy transplanted hairs. In areas of extensive
miniaturization, it may be appropriate to transplant follicular units in the
same density as one would if the area was totally bald ass the miniaturized
hair may be lost by the time transplants grow.
However, regardless of the “claims” of a particular
surgeon, the process is a natural response of hair follicles and the risk cannot
be eliminated completely.
