Retrospective Study of Reoperation After Primary Augmentation With NATRELLE® INSPIRA® Breast Implants

* Primary breast augmentation (either bilateral or unilateral) operated on by the investigating surgeon with an infra-mammary approach smooth or textured NATRELLE® INSPIRA® TruForm® 1 or 2 device * Primary breast augmentation 2 to 4 years (24-48 months) prior to data collection * Subfascial, submuscular, dual plane or subglandular implant placement

* Breast augmentation for Poland Syndrome or amastia * Breast reconstruction following mastectomy * Revision or secondary breast reconstruction * Non NATRELLE® INSPIRA® device implanted at initial breast augmentation * Women diagnosed with breast disease considered to be pre-malignant or malignant prior to or at the time of primary breast augmentation * Surgical procedures of the breast not related to the primary breast augmentation (e.g. excision of significant skin lesions or a biopsy) occurring prior to or at the time of primary augmentation that may adversely affect the aesthetic outcome in the opinion of the investigator * Axillary or peri-areolar approach * Mastopexy augmentation
