Breast Implants overview
The main
qualities necessary for an implant are:
▪ flexible (of consistency
close to the breast tissues)
▪ supported well by
surrounding tissues
▪ solid, resistant to wear,
▪ of aesthetic form, giving a
natural aspect to the bust.
▪ the silicone
gel: it is obligatorily cohesive today, meaning
that if the implant is broken gel cannot run out. It is certainly the best
produced current filling and more used.
▪ physiological
salt solution (water + sodium chloride) less and
less used.
▪ others
(hydrogel, oils…) not currently authorized in France
1995 to 2000 the use of breast implants containing silicone
gel was prohibited in France, because the responsibility for this gel had been
evoked in the appearance of autoimmune diseases; The studies made so far did
not make it possible to prove this
possibility.
Thus, since containing January the 2000 prostheses of the
silicone gel are again authorized in France, but must meet standards of quality
and very precise manufacture before being put on a case-by-case basis on the
market:
. Gel must be cohesive (cf above)
. The envelope while remaining flexible must be thicker,
answering precise criteria of solidity, to limit the risk of rupture, and
sealing to limit the silicone transudation through the membrane.
Thus the day saw what it is advisable to call the prostheses
in silicone gel of new generation much sedentary than the old ones.
All this is important because the silicone gel contained in
the implant semi is polymerized and is irritating for surrounding tissues being
able to cause various inflammatory reactions.
In spite of their qualities, these prostheses will undergo like the preceding
ones a wear in time and will have to be replaced of principle before their
rupture (see hereafter § “period of validity of the implant”.
For the period of prohibition of the silicone gel, only the implants containing
of the physiological salt solution were authorized: their use showed that they
were responsible for visible folds, wrinkles and gondolages under the skin,
especially in the thin patients and that they deflated capriciously, sometimes
precociously (after a few months or years) while boring by wear on a fold.
Their use is thus today in Net retreat.
It out of silicone is always polymerized, substance
tolerated well by tissues.
While being flexible, it must be sufficiently thick and
tight.
It perhaps smooth or generally textured, meaning presenting
of fine granulations which decrease the risks of capsulite retractile or
“hulls” (cf hereafter § complications)
▪ the round
prostheses have a circular base and are
symmetrical on all the axes.
▪ the “anatomical”
prostheses have the shape in tear drop, being more punts
with their higher pole; their base perhaps higher than broad or conversely.
The objective of these anatomical prostheses is to obtain a centre less curvature
on the level of its higher pole, and their use is often necessary to this end
when the implant is placed in front of the pectoral large muscle; in the
position retro muscular pressure of the pectoral muscle on the higher pole of
the implant fear of being enough to decrease this convexity.
The anatomical prostheses can sometimes “turn”, which modifies the form of the
centre inesthétiquement and can require a reintervention.
There are in addition prostheses at broad, less projected base (Low profile)
and others at narrower and more projected base (High Profil).
Your surgeon will choose the type of implant adapted best to your wishes, with
the morphology of your centres, your thorax and your silhouette in order to
obtain the best aesthetic result.
