Since 2006, silicone breast implants have been approved again for breast augmentation. These are new-generation silicone breast implants that are filled with a new gel formulation of silicone that promises not to leak or bleed and be more durable than the old silicone breast implants that were used from the late 1970s to 1992. The long-term data on these newer silicone breast implants is relatively short, while we have 15 years of long-term data on saline breast implants. How, then, do they compare?
In a recent February 2008 editorial in the journal of Plastic and Reconstructive Surgery journal, it compared the scientific data of both types of breast implants. Here are the highlights of this analysis:
1) Patient satisfaction is high with either saline or silicone breast implants.
2) Saline breast implants need a smaller incision to be placed and cost less than silicone.
3) For breast cancer imaging, both breast implant types require additional views on
mammography to adequately image the breast.
4) Saline implants have a decreased capsular contracture and rupture rate than
silicone breast implants.
5) Saline breast implant rupture can be seen, silicone breast implant rupture can not be
seen on the outside and requires an MRI to detect.
6) Breast augmentation is not a forever, one-time operation. Many patients will eventually
require revisional surgery at some point in their remaining lifetime, often to replace their
implants.
These findings support what I tell every breast augmentation consult. Neither saline nor silicone breast implants are perfect, each has its own unique set of advantages and disadvantages. Both of them will do the job and do it satisfactorily, make the breasts bigger. Saline breast implants have an exceptional safety history, are less expensive, and can be placed through a small incision that is away from the breast (armpit)…….but one has to accept some implant rippling/wrinkling, less of a natural feel, and the immediate deflation of the breast should the implant rupture. Silicone breast implants are not as well studied, require a bigger incision in the crease of the breast fold to place, and are more expensive…. but with the benefits of a more natural feel, virtually no rippling, and lack of any breast changes (in the short-term) if the implant should rupture.
How does a patient choose? I tell patients make your choice based on which of their disadvantages you can live with the best. Both saline and silicone implants work for breast augmentation…which of their disadvantages is more acceptable to you?
