| We mainly use facial implants in chin
augmentations, but also to fill cheeks, forehead, mandible and maxilla, enlarge
lips and fill lines that go from nose to mouth. We placed a silicone prosthesis
in the maxilla of the patient in the photograph and methacrylate in the lips.
An implant is any non-organic material that is introduced into the organism.
We recommend implants in hypotrophy or atrophy cases of both soft-tissue and
bone when we don't have own material or its obtainment is bloodier or doesn't
improve the result achieved by that implant.
We use solid silicone prosthesis and Gore-tex in thread or strip more often.
Some thread extrusion can occur, but it is usually not a problem. Both implant
types are permanent and easily extractable.
Liquid silicone in microgranule or biopolymer form belongs to the group of
inorganic substances. In Spain, its use in plastic surgery is currently banned.
The filling procedure used is not only due to the volume introduced but also
because of the fibroses it causes. The key for a good result is not to pretend
to obtain the definite shape in one application, but to do it gradually in different
steps: first, a minimum quantity is injected and the type of reaction is observed;
second: filling; third: perfectioning. It is convenient to wait one month from
one application to the other so that the fibrosis can form. The fundamental principle
is to sculpt lips not fill them.
The area can be anesthesized through ice or blocking. Imprecise and individual
duration of results. It usually lasts many years. As Artecoll, it can cause swelling
with a very severe fibrosis reaction or the silicone can move to other parts of
the body and even surface. Insertion in nasogenian grooves and periorbital wrinkles
must be avoided since it can cause swelling of the whole area.
Collagen. Bovine collagen is one of the most widely used organic compositions,
which has short lasting effects and can provoke allergic reactions. It is necessary
to undergo an allergy test and a negative result does not guarantee that there
is no risk of suffering an allergic reaction during the inclusion.
Artecoll. Current equivalent of silicone. Polymethacrylate microspheres (around
40 micras) in a liquid collagen and lidocaine suspension. Theoretically, its advantage
is that the facial flaw can be corrected in one session. An allergy test is also
required due to the collagen contained in its composition.
