Collagen or Fat Injection
Procedure: Injecting soft-tissue fillers,
most commonly injectable collagen or fat, to help fill in lines and
creases, temporarily restoring a smoother, more youthful-looking
appearance.
Length: 15-45 minutes.
Anesthesia:
Collagen: Because the anesthetic agent lidocaine is mixed in with collagen, additional
anesthetic is usually not used. However, if you are especially sensitive to pain,
your doctor may use a topical cream anesthetic or a freon spray to numb the injected
area. Or, you may elect to have an injected local anesthetic or sedative drugs.
Fat: Both the donor and recipient sites are numbed with local anesthesia.
Sedation can be used as well. If you elect to use sedation, be sure to arrange
for a ride
home after your treatment.
In/Outpatient: Usually outpatient.
Risks: Because individuals vary greatly in their anatomy,
their physical reactions and their healing abilities, the outcome of treatment
with injectables is never completely predictable. However, when injectables are
administered by a qualified plastic surgeon, complications are infrequent and
usually minor in nature.
Collagen: Allergic reaction is the primary risk of collagen. To help determine
if you are allergic to the substance, your surgeon will perform an allergy skin
test about a month before the procedure. After the test is performed, the test
site should be watched carefully for three or four weeks, or as long as your
surgeon advises. Any sign of redness, itching, swelling or other occurrences
at the test site should be reported to your surgeon.
Risks not necessarily related to allergies include infection, abscesses, open
sores, skin peeling, scarring and lumpiness, which may persist over the treated
area. Reports of these problems are very rare.
Fat: Allergic reaction is not a factor for fat because it's harvested from a
patient's own body. However, there is still a small risk of infection and other
infrequent complications.
Duration of Results: The duration
of the fat injections varies significantly from patient
to patient. Though some patients have reported results
lasting a year or more, the majority of patients find
that at least half of the injected fullness disappears
within 3-6 months. Therefore, repeated injections may
be necessary. Your doctor will advise you on how to maintain
your results with repeat treatments.
