Currently, there are different kinds of breast implants depending on their composition, shape or surface. According to its composition, prostheses are filled with:
– Cohesive silicone gel.
– Silicone polyurethane outer coat.
As we see, all of them in a more or a lesser extent are formed by silicone. As for the implant surface, they can be distinguished between smooth and textured. The basic difference is that some are not going to adhere to the periprosthetic tissue and the others do.
As for the form, they are available in round and anatomical shape or drop-shaped. The latter try to mimic the natural shape of the breast. Undoubtedly, the most popular implants are the ones filled with cohesive silicone gel for the most natural feel and lower frequency of rippling or visible wrinkling. Saline-filled prostheses, which were widely used in the US, are less implemented today, although they are radiolucent (they do not interfere the vision in radiologic examinations) and, whether they break, its content is saline.
Implants with polyurethane outer coat are mainly recommended in recurrent cases of capsular contracture. As for the combination of the implant surface and its form, note that there are mandatory combinations such as the anatomical ones, which are roughened to facilitate their adherence to the surrounding tissue and prevent rotation occur. By contrast, round implants surface can be rough or smooth since no adherence is sought.
As we see, there is a broad range of possibilities at the time of the choice of an implant. Female candidates to this type of intervention must be informed of the type of implants that exist and consult with their surgeon at the time of their choice.
