The confusion about the difference between silicone and saline implants used in Breast Enlargement surgery raises questions about the safety of silicone gel. From the early 1990′s though until 2006 the FDA in the United States banned the use of silicone gel in Breast Implants. This resulted from claims that silicone gel leakage from breast implants was causing harm to many breast implant recipients.
For many years prior to 1993, the most common breast implant was a silicone bag filled with a liquid silicone gel. Leakage from these implants was a well known problem more for the uneven-ness in breast size that the leakage caused than for any other problem. Then, as a result of the subsequent ban on silicone implants, manufacturers created a similar liquid gel from saline, the idea being that any leakage that occurred would be similar to body fluids, would be absorbed into the body and cause no harm.
The key problem here was that is was based on the assumption that all implants leaked. Hence the addidtional problem of unevenness of breasts due to loss of gel from leaking was not fixed.
Then along came a major advancement with the development of cohesive silicone gel, which due to its sticky, thicker consistency, and being encased in a silicone shell without a valve, virtually eliminated the “leakage” problem.
In 2006 the FDA approved the use of cohesive silicone gel implants. These cohesive silicone gel implants are soft and feel much more like a natural breast than either of the previous implant types, either liquid silicone gel or liquid saline gel. Liquid Saline gel implants are still the only saline implants available today. Apparently Cohesive Saline Gel implants are under review by the FDA and may be approved sometime in the future.
Hence at the time of writing this blog Cohesive Silicone Gel implants are the only implants which do not leak. So, if you are wondering what can happen to these implants then the focus is on the likelihood of a rupture or split.
There is a small percentage, around 3% worldwide, of recorded implant rutpures. And it is the cohesive nature of the gel which keeps the gel close together around a rupture or split. The idea being that the gel won’t migrate into other areas of the body due to its cohesiveness. This is not ideal, because the same principle of the body not absorbing silicone as it does saline applies to that small number of cases with ruptures.
The closer to ideal answer will be with cohesive saline gel implants once they are approved.
