The first category of procedures
would be those that add volume to the lip by a simple
injection. The first material used commonly was silicone, and
when used properly, produced excellent results. The present
choices include:
- BOVINE COLLAGEN
- FAT
- SCAR
- FASCIA
- GORTEX
None of these methods are great,
otherwise all the doctors would switch to it.
COLLAGEN
In place of silicone, a common
material used is bovine collagen, produced by the Collagen
Corporation. Collagen is the body's
natural filler material, the cement that holds the tissues
together. It is a very simple protein that tightens like
rope. Collagen is the main material in tendons,
ligaments, the dura around the brain, and even the main
support substance of skin.
The Collagen Corporation
sells bovine collagen to physicians. This is an extract
of cow skin that is homogenized and sold to physicians in a
suspension that has been loaded into syringes. All physicians
pay the same price for the materials. The material is
not altered by any physician either, so feel free to shop for
the best price for this material.
FAT INJECTION
Another filler that adds
bulk is fat, which can be transferred from other areas of the
body. In this case a region is suctioned, the fat is
washed, and then reinjected into the lips. This may
produce a satisfactory improvement, in some cases; however,
usually only a small portion of the fat survives. The
fat may be lumpy when it finally heals.
In our office we consider
the results of fat injection too unpredictable, especially in
the lip. Also, there is considerable work involved in
harvesting and transferring. Generally I tell patients
that they can expect that in fifty percent of patients the fat
is gone between six months to a year, but it is truly hard to
be exact.
SCAR AND FASCIA
PLACEMENT
Another method of lip
enhancement is dermal grafting, in which a strip of skin or
scar tissue is removed from another area of the body and slid
into the lip as a whole strip of tissue. If the patient
has a good donor area (place to take the graft from), in
particular where there is an excess fold or some other
procedure is being done that will make it convenient to
harvest tissue, I may recommend this method for them as
well. Although this procedure
may be a good deal of work, this can produce a satisfactory
long-term result with natural tissue. The lip may tend
to be stiff for a while and certainly a little numb as well,
but this technique may add significant volume.
Instead of skin or scar,
FASCIA has been used, particularly if lip augmentation is
desired at the time of a facelift. Fascia is a thick
sheet of natural collagen that holds deep tissues like muscle,
in place. My experience with this is that it tends to
reabsorb, without providing the desired volume over a long
period of time.
GORTEX
Gortex is a Teflon sheet
material that is FDA approved. It is introduced in the
lip in long strips in a fashion that is similar to the dermal
grafting. The material tends to be thin and I think adds
very little real volume to the lip. This technique may
be more appropriate for accenting lip lines. Even though
there is no evidence of problems with Gortex so far, some
people are concerned about having a foreign material in their
body if there is some other procedure that might work as
well.
