ABSTRACT: At least 15% of silicone breast implants will rupture within 10 years after implantation.
COMMENTARY: Although several studies have estimated the rate of implant rupture, none have directly examined the actual rates.
The research team performed magnetic resonance imaging (MRI) testing in a group of 186 women who had received silicone breast implants at least 3 years prior. A total of 317 implants were unruptured at the start of the study in 1999. At follow-up in 2001, a total of 280 implants remained in place and 37 had been removed.
The researchers identified 33 (10%) definite ruptures and 23 (7%) possible ruptures that occurred during the study period. Based on this, 5.3 definite ruptures were estimated to occur for every 100 implants each year.
Implant age was one of the strongest predictors of rupture, the authors note. For example, implants that were 6 to 7 years old were nearly three times more likely to rupture than those that were only 3 to 5 year old.
When the analysis was limited to the newest implants--those developed in 1988 or later--the authors estimated that at least 15% will rupture within 10 years of placement. For these implants, the rate of rupture dramatically rises 6 to 8 years after placement.
Although some surgeons advocate routine implant exchange after 10 years, "this may give a false sense of security" since many will have ruptured by that time, the authors note.
