It was made to determine the failure rate of the implants and other accompanying complications. The results were astonishing. In 7 to 12 years after the implantation the failure rate will be in the region of 15.9-.8%.
Lead author of the study Mr. Jan Stanek says, "Previous studies have typically reported failure rates of between 2% and 5% and these estimates have been based on secondary data. In this study, all participants were scanned by ultrasound, which provides conclusive indication of rupture, rather than clinical examination which is typically used. Most previous studies were based on multiple surgeon, multiple technique, with a relatively small number of patients and shorter follow up time span."
Concerns about the durability of PIP implants have already been expressed in UK before it was formally removed from the market in 2010. Another hit affected PIP as it was thought to have caused certain forms of cancer like ALCL. It also made a global concern after it was revealed that they [implants] contained industrial silicone instead of medical-grade fillers.
The Medical Healthcare Products Regulatory Agency (MHRA) said " ... most breast implants manufactured by the company since 2001 have been filled with a silicone gel with a composition different from that approved".This statement was made in 2010.
As a result of these facts, NHS medical director Professor Sir Bruce Keogh who led the expert review group regarding the product said, “On the basis of the information we have, we do not think it is necessary to recommend the routine removal of these implants.But we understand that some women will be very concerned so we support the government’s position that the NHS will support removal of PIP implants if the patient has concerns and, with her doctor, she decides that it is right to do so.”
According to http://www.drmotykie.com, a renowned plastic surgery provider, “I can’t say where these things will lead to but it’s important to give the patients what’s due to them without compromising their health…”
Further investigation is being made for which NHS director Sir Bruce Keogh said, “I am working with experts from the plastic surgery field to look at what we can do to make sure people who choose to have cosmetic surgery and other cosmetic procedures are safe.”
