Study Finds 8 Percent Rupture Rate for Breast Implants
Silicone implant rupture rate 8 percent or lower over 11 years, says Inamed-funded study
TUESDAY, Aug. 22 (HealthDay News) -- Fewer than 10 percent of Inamed brand silicone implants ruptured over an 11-year period, according to a company-funded study published in the August issue of Plastic and Reconstructive Surgery.
Per Heden, M.D., of Akademikliniken Hospital in Stockholm, Sweden, and colleagues conducted a multicenter, cross-sectional study of 106 women with at least one Inamed silicone breast implant. Using magnetic resonance imaging technology, they acquired long-term rupture data specific to third-generation silicone breast implants made by Inamed.
During a mean implantation time of 10.9 years, the authors found no evidence of rupture in 92 percent of the 199 implants evaluated. The remaining 8 percent either showed evidence of rupture (6 percent) or were indeterminate and considered ruptured (2 percent).
"Our results provide further evidence to suggest that Inamed silicone breast implants have a low long-term prevalence of rupture," the authors wrote. "Additional study is warranted to establish the long-term incidence of rupture and determine whether the rupture rate progresses in a linear fashion throughout the lifetime of the implant."
The study was funded by the Inamed Corporation, and some of the authors are Inamed employees.
