What types of prostheses are there?
It is important to know the type of prosthesis because it implies the consequences of its breakage.
All prostheses are made of an external material, usually silicone, that forms the cover and acts as a container and a filling that gives volume to the implant. There are two main classes depending on the material used for the filling:
1. Saline prostheses: they are filled with a liquid substance made up of water and salt, similar to what is called physiological serum, and which we find naturally in our body.
2. Silicone gel prostheses: they are the most widely used at present and they are denser in texture than saline. The basis of its composition is silicone and the latest generation and most recommended are those of high cohesiveness.
What types of break are there?
Depending on how the content of the prosthesis spreads when broken, two types of rupture are distinguished.
1. Intracapsular rupture: occurs when the content of the prosthesis remains inside the cover or is contained by the scar tissue generated around the implant. They involve less risk since the filling of the prosthesis hardly comes into contact with the tissues of our body. Some studies show that three quarters of ruptures are of this type but that within two years 10% of these ruptures progressed to extracapsular. This evidence indicates that early detection of breakage reduces risks and the expansion of the filling to other areas.
2. Extracapsular rupture: it occurs when the contents of the implant expands outside the cover and the capsule that the tissues form around the prosthesis. Typically, the gel or liquid is in nearby areas, but can move to the axillary nodes, the rib cage, the abdominal area or even through the upper limb. The expansion of the silicone gel to these areas can produce granulomas or siliconomas that are the natural reaction of our body against a foreign body and that we can perceive as small lumps palpable to the touch at times.
