Results reported in the Journal of Plastic, Reconstructive and Aesthetic Surgery
New research published in the Journal of Plastic, Reconstructive and Aesthetic Surgery suggests that the failure rate of silicone breast implants manufactured by Poly Implant Prosth-se (PIP) could be as high as 33.8%.
Patients who received PIP implants either for primary or secondary breast augmentation, between January 2000 and August 2005, were studied to determine implant failure rate and other complications. Results found that 7 to 12 years after implantation the failure rate for PIP implants is in the region of 15.9.8%.
"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," commented Mr. Jan Stanek, lead author of the study.
Concerns about the durability of PIP silicone breast implants have been expressed for several years prior to their formal withdrawal from the UK market in March 2010. Although precise details of what elements were at fault remain unclear, concerns have been raised about both the elastomer (the outer cover of the implant) and the filler gel.
In this study PIP implants were used by the plastic surgeon for both primary and secondary breast augmentation. A database of patients was constructed and each patient was offered a free consultation and referral for ultrasound scan. Chief outcome measures included secondary surgery, implant rupture rate and time to rupture.
