Memory Gel and Shape Combined Cohort

The purpose of this study is to collect additional post-approval clinical data on the long-term performance of MemoryShape and MemoryGel Breast Implants, as indicated for primary or revisional breast augmentation and primary or revisional breast reconstruction.

The post-approval study will include a maximum of 3500 women undergoing breast augmentation or reconstruction with MemoryShape or MemoryGel Breast Implants. Four cohorts will be included: primary augmentation, revision-augmentation, primary reconstruction, and revision-reconstruction. For the purpose of assessing rheumatological and neurological signs and symptoms, a control group with 300-480 women will be selected from the participating investigators' practices, who are undergoing an aesthetic surgery other than breast implant surgery. Breast implant patients and the concurrent control group patients will be followed for 10 years. Baseline and operative data will be collected at the beginning of the study, and follow-up data will be collected annually for 10 years through online questionnaires.
