The Allergan Core Study for Revision-Augmentation with INAMED® Silicone Breast Implants showed 32 implant removals performed in 18 prevision-augmentation patients. 26 of the 32 implants were replaced. 9 of the procedures may be attributed to capsular contracture – the most common reason for removal. The follow-up spans 4 years.
