The Summary of Safety and Effectiveness for each of the FDA-approved saline- and silicone gel filled breast implants details safety information known at the time of FDA approval. As the FDA learns of new safety information, it requires companies to update their product labeling. The most current safety information about saline- and silicone gel-filled breast implants can be found in the labeling.
The ASPS and the Plastic Surgery Foundation (PSF) have partnered with the FDA to study this condition and in doing so created the Patient Registry and Outcomes For breast Implants and anaplastic large cell Lymphoma Etiology and epidemiology (PROFILE). The United States FDA strongly encourages all physicians to report cases to PROFILE in an effort to better understand the role of breast implants in ALCL and the management of this disease.
Since the early 1990s, a number of independent systemic comprehensive reviews have examined studies concerning links between silicone gel breast implants and claims of systemic diseases. The consensus of these reviews (outlined below under Safety of Breast Implants heading) is that there has been no evidence of a causal link between the implantation of saline or silicone breast implants and systemic disease After investigating this issue, the U.S. FDA has concurred and since reaffirmed that “the weight of the epidemiological evidence published in the literature does not support an association between fibromyalgia and breast implants.”. A comprehensive systemic review by Lipworth (2011)  concludes that "any claims that remain regarding an association between cosmetic breast implants and CTDs are not supported by the scientific literature".
Case 3: A curvature and droopy tip brings undue focus to this young man’s nose. Although there is still some swelling in these early post-operative photos, we can already see a nose that is now straight, has a smooth profile and no longer droops. A sense of length is preserved to match his oval face. More than that, because of these positive changes, he also looks younger.
In the 1980s, the models of the Third and of the Fourth generations of breast implant devices were sequential advances in manufacturing technology, such as elastomer-coated shells that decreased gel-bleed (filler leakage), and a thicker (increased-cohesion) filler gel. Sociologically, the manufacturers of prosthetic breasts then designed and made anatomic models (natural breast) and shaped models (round, tapered) that realistically corresponded with the breast- and body- types of women. The tapered models of breast implant have a uniformly textured surface, which reduces the rotation of the prosthesis within the implant pocket; the round models of breast implant are available in smooth-surface- and textured-surface- types.
Case 31: This patient had some typical concerns of feeling washed out from the front with flattening and spreading of her tip. She was very happy with the narrowing and definition achieved for her bridge and tip along with nostril reduction. In addition, chin augmentation increased chin projection to improve the balance of her lower face and jawline.
Because a breast implant is a Class III medical device of limited product-life, the principal rupture-rate factors are its age and design; Nonetheless, a breast implant device can retain its mechanical integrity for decades in a woman's body. When a saline breast implant ruptures, leaks, and empties, it quickly deflates, and thus can be readily explanted (surgically removed). The follow-up report, Natrelle Saline-filled Breast Implants: a Prospective 10-year Study (2009) indicated rupture-deflation rates of 3–5 per cent at 3-years post-implantation, and 7–10 per cent rupture-deflation rates at 10-years post-implantation.
Case 69: This patient was bothered by his prominent ears and a sense of width to his nose that made it feel bulky and unrefined in his view. While still preserving his ethnic identity, he was able to achieve a meaningful improvement in nasal balance. Bringing his ears back into the vertical plane helped to make them less noticeable and remove them as a source of focus for him.
I had wrongly assumed he could simply flatten the hump and be done, but he explained that you can't sculpt one area without considering how it'll impact everything else. If he smoothed the bridge and did nothing else, my nose could wind up looking far too wide from the front. So ultimately, he would need to break my nose and seamlessly draw it in closer to create the precise size and shape I was after. He'd also have to reduce the cartilage at the tip and turn it up slightly, from 91 to 93 degrees. In the end, my nose would be smaller, with a straighter bridge, a refined tip, and more clearly defined nostrils.
Transaxillary: an incision made to the axilla (armpit), from which the dissection tunnels medially, to emplace the implants, either bluntly or with an endoscope (illuminated video microcamera), without producing visible scars on the breast proper; yet, it is likelier to produce inferior asymmetry of the implant-device position. Therefore, surgical revision of transaxillary emplaced breast implants usually requires either an IMF incision or a periareolar incision.
After reviewing the medical data, the U.S. Food and Drug Administration concluded that TDA-induced breast cancer was an infinitesimal health-risk to women with breast implants, and did not justify legally requiring physicians to explain the matter to their patients. In the event, polyurethane-coated breast implants remain in plastic surgery practice in Europe and in South America; and no manufacturer has sought FDA approval for medical sales of such breast implants in the U.S.
