In 1988, twenty-six years after the 1962 introduction of breast implants filled with silicone gel, the U.S. Food and Drug Administration (FDA) investigated breast implant failures and the subsequent complications, and re-classified breast implant devices as Class III medical devices, and required from manufacturers the documentary data substantiating the safety and efficacy of their breast implant devices. In 1992, the FDA placed silicone-gel breast implants in moratorium in the U.S., because there was “inadequate information to demonstrate that breast implants were safe and effective”. Nonetheless, medical access to silicone-gel breast implant devices continued for clinical studies of post-mastectomy breast reconstruction, the correction of congenital deformities, and the replacement of ruptured silicone-gel implants. The FDA required from the manufacturers the clinical trial data, and permitted their providing breast implants to the breast augmentation patients for the statistical studies required by the U.S. Food and Drug Administration. In mid–1992, the FDA approved an adjunct study protocol for silicone-gel filled implants for breast reconstruction patients, and for revision-surgery patients. Also in 1992, the Dow Corning Corporation, a silicone products and breast implant manufacturer, announced the discontinuation of five implant-grade silicones, but would continue producing 45 other, medical-grade, silicone materials—three years later, in 1995, the Dow Corning Corporation went bankrupt when it faced large class action lawsuits claiming a variety of illnesses.
In the mid-twentieth century, Morton I. Berson, in 1945, and Jacques Maliniac, in 1950, each performed flap-based breast augmentations by rotating the patient's chest wall tissue into the breast to increase its volume. Furthermore, throughout the 1950s and the 1960s, plastic surgeons used synthetic fillers—including silicone injections received by some 50,000 women, from which developed silicone granulomas and breast hardening that required treatment by mastectomy. In 1961, the American plastic surgeons Thomas Cronin and Frank Gerow, and the Dow Corning Corporation, developed the first silicone breast prosthesis, filled with silicone gel; in due course, the first augmentation mammoplasty was performed in 1962 using the Cronin–Gerow Implant, prosthesis model 1963. In 1964, the French company Laboratoires Arion developed and manufactured the saline breast implant, filled with saline solution, and then introduced for use as a medical device in 1964.
Subfascial: the breast implant is emplaced beneath the fascia of the pectoralis major muscle; the subfascial position is a variant of the subglandular position for the breast implant. The technical advantages of the subfascial implant-pocket technique are debated; proponent surgeons report that the layer of fascial tissue provides greater implant coverage and better sustains its position.
The woman wanting a lift is usually slightly different. She had breasts she was happy with before, she had loving kids who she may or may not have breastfed, exercised and had a good life. They come wanting to restore the youthful breast they once they had(or better), they hate that it is slightly more deflated than before and it's slightly more south then they'd like. The formal name of this operation is "Mastopexy" and that's why you hear terms like "Mastopexy augmentation" because often in order to restore the youthfulness of the breast you not only need to reposition the nipple/areolar complex "up" with a mastopexy, you also need to provide some additional volume with an implant, hence augmentation as well. The discussion with implant also is entirely different discussion all together, but this highlights the primary difference in the reduction and a lift.
The FDA has identified that breast implants may be associated with a rare form of cancer called anaplastic large-cell lymphoma, believed to be associated with chronic bacterial inflammation. Similar ALCL phenomena have been seen with other types of medical implants including vascular access ports, orthopedic hip implants, and jaw (TMJ) implants. As of February 1, 2017, the FDA has received a total of 359 medical device reports of breast-implant-associated ALCL (BIALCL), including 9 deaths. Most cases of breast implant-associated ALCL had implants in for many years prior to the condition, and are usually treated successfully by simple removal of the implant and the capsule surrounding the implant without the need for chemotherapy if no evidence of systemic disease exists. If women with implants present with delayed swelling or fluid collection, cytologic studies and test for a marker "CD30" are suggested. The American Society of Plastic Surgery (ASPS) states, "CD30 is the main diagnostic test that must be performed on the seroma fluid as routine pathology or H&E staining can frequently miss the diagnosis."  Diagnosis and treatment of breast implant associated ALCL now follows standardized guidelines established by the National Comprehensive Cancer Network.
