  Purpose
In November 2006, U.S. Food and Drug Administration (FDA) approved Mentor's MemoryGel silicone gel-filled breast implants for use in women who are undergoing primary or revisional breast augmentation and primary or revisional breast reconstruction surgery. This postapproval study is intended to satisfy one element of FDA's postapproval monitoring requirements. In January 2015, the FDA approved a protocol amendment that limits the scope of data collection for the study to the collection of only secondary procedure/reoperation data for MemoryGel participants.

Primary Outcome Measures:
  • Kaplan-Meier Estimated Cumulative Incidence Rate of Breast Surgery Reoperations [ Time Frame: through 10 years ]
    The cumulative incidences of reoperations through 10 years for women with MemoryGel breast implants will be estimated based on surgeon reporting using Kaplan-Meier methodology

  • Kaplan-Meier Estimated Cumulative Incidence Rate of Breast Implant Explantations [ Time Frame: through 10 years ]
    The cumulative incidences of explantations through 10 years for women with MemoryGel breast implants will be estimated based on surgeon reporting using Kaplan-Meier methodology


Secondary Outcome Measures:
  • Reasons for Breast Surgery Reoperations [ Time Frame: through 10 years ]
    Frequencies of the reason for reoperation will be computed for women with MemoryGel breast implants through 10 years


Enrollment: 43046
Study Start Date: November 2006
