What did the Core Studies show regarding the rate of rupture and the consequences of rupture?
Rupture rate and consequences of rupture were characterized for each Core Study. Consequences of rupture include intracapsular rupture (when the gel remains within the scar tissue capsule surrounding the implant), extracapsular gel (when the gel moves outside the capsule but remains within the breast tissue), migrated gel (when the gel moves beyond the breast), and clinical consequences. Rupture rate was assessed for patients who had scheduled MRIs to screen for non-symptomatic, or silent, rupture (the MRI cohort), as well as for those who did not have scheduled MRIs to screen for silent rupture (the non-MRI cohort).

For the Mentor Core Study, all reported ruptures were from patients in the MRI cohort. The rupture rates were 0.5% for primary augmentation, 7.7% for revision-augmentation, 0.9% for primary reconstruction, and 0% for revision-reconstruction through 3 years. There were 8 ruptured/suspected ruptured implants in 6 patients through 3 years. Two of the implants were explanted a
