Smooth breast implants are round in shape, come in many sizes and are available with different profiles, which is the amount of projection of the breast silhouette from the chest. The shells of smooth breast implants are slightly thinner than textured implants. Smooth implants are less likely to cause rippling of the implant shell and are less likely to rupture.
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.
Healing from a breast implant surgery is not a set timeline. Each patient is different and their body heals at different rates. The actual incision made on the breast will typically heal in about 3-5 days. There will also be absorbable sutures that typically can be removed after 45 days. There will also be bruising present after the surgery, and it can take about one to two weeks to completely disappear. Most pain felt from this surgery is from the muscle being stretched. Generally the patient will be prescribed a pain medication, and depending on their situation their Doctor may also prescribe a muscle relaxant to help the muscle adapt to the new implant. Most patients have reported that after three to four days the pain has significantly subsided and they are able to resume normal activities, such as, driving. The Doctor will also be able to show you various exercises that will help the muscle stretch and assist the implants with settling not the new space more quickly.
The breast implant has no clinical bearing upon lumpectomy breast-conservation surgery for women who developed breast cancer after the implantation procedure, nor does the breast implant interfere with external beam radiation treatments (XRT); moreover, the post-treatment incidence of breast-tissue fibrosis is common, and thus a consequent increased rate of capsular contracture. The study Breast Cancer Detection and Survival among Women with Cosmetic Breast Implants: Systematic Review and Meta-analysis of Observational Studies, reported an average later stage in the diagnoses of women who developed breast cancer after undergoing breast augmentation, when compared to breast cancer patients who had not undergone breast augmentation, although this did not ultimately affect the patients prognosis. The use of implants for breast reconstruction after breast cancer mastectomy appears to have no negative effect upon the incidence of cancer-related death.
A breast lift, also known as a mastopexy, is most beneficial for women who have sagging breasts. This type of procedure reshapes and supports the breast tissue to achieve a more youthful figure. It also helps restore the shape and volume that may have been lost due to age, weight loss or breastfeeding. Because a breast lift repositions the location of the breasts, they can appear smaller. However, only excess skin is removed, not the actual breast tissue. Often with breast lifts, the nipple and areolas are repositioned and reduced in size to create a more natural look.
A breast reduction, or a reduction mammoplasty, can reduce a significant amount of volume and alleviate excess weight in the breast area. It does this by removing excess skin, fat and tissue to reduce the size of the breasts. This procedure is beneficial for women who are seeking to reduce the size of their breasts because of health issues or personal preference. Often when the breast reduction procedure is performed, women experience a much more lifted appearance. Some patients opt to have their areolas reduced or in some cases have their excess tissue sent off to be screened for breast cancer.
A great question that comes up often. A breast reduction will both reduce the breast size and improve the shape of the breast while lifting it. During this surgery, breast tissue is removed while preserving the tissue around the nipple. The breast is then shaped and nipple placed in a higher, more ideal position. This is essentially the breast lift component of this surgery. With the reduction, we are accomplishing both. Hope this helps.
The first step toward finding out if you are a candidate is a thorough consultation with a board-certified plastic surgeon who has extensive experience performing breast augmentation. He or she will examine your breasts, your skin tone and the rest of your anatomy to help determine if you are an appropriate candidate. You also may have the option of viewing plastic surgery photos from past patients to better gauge expectations. Other factors, including breast augmentation cost and whether your lifestyle and commitments will allow you to take enough time off to recuperate properly, also play a role in determining your candidacy.
The plastic surgical emplacement of breast implant devices, either for breast reconstruction or for aesthetic purpose, presents the same health risks common to surgery, such as adverse reaction to anesthesia, hematoma (post-operative bleeding), late hematoma (post-operative bleeding after 6 months or more), seroma (fluid accumulation), incision-site breakdown (wound infection). Complications specific to breast augmentation include breast pain, altered sensation, impeded breast-feeding function, visible wrinkling, asymmetry, thinning of the breast tissue, and symmastia, the “bread loafing” of the bust that interrupts the natural plane between the breasts. Specific treatments for the complications of indwelling breast implants—capsular contracture and capsular rupture—are periodic MRI monitoring and physical examinations. Furthermore, complications and re-operations related to the implantation surgery, and to tissue expanders (implant place-holders during surgery) can cause unfavorable scarring in approximately 6–7 per cent of the patients.  Statistically, 20 per cent of women who underwent cosmetic implantation, and 50 per cent of women who underwent breast reconstruction implantation, required their explantation at the 10-year mark.
When it comes to determining the prominence and size to utilize for the breast augmentation, the first step is to determine what are your goals/desires for the end result. Once you have decided on what you would like the final result to look like, the surgeon will make recommendations and suggestions based on your body type and build as to what they know will be able to achieve your goal, or get you as close to them as safely possible. An individual may want a specific size, but the surgeon will be able to tell if that is a realistic option for that individual or not. For example, if the patient’s chest is small and the breast tissue is tight, it will not be recommended to use a large implant as it will not fit. This is why a surgeon with clinical experience is beneficial, because they will be able to help you understand and guide you towards the best implant for your body. It is not uncommon for patients to become focused on details such as the actual volume of CC’s, however, you need to keep in mind that there are many varying factors that have to be considered by the surgeon when recommending the best implant for your body so try not to get too caught up in those details and trust your surgeon.
1998 Germany Federal Institute for Medicine and Medical Products Reported that "silicone breast implants neither cause auto-immune diseases nor rheumatic diseases and have no disadvantageous effects on pregnancy, breast-feeding capability, or the health of children who are breast-fed. There is no scientific evidence for the existence of silicone allergy, silicone poisoning, atypical silicone diseases or a new silicone disease."
Round breast implants come in a wide array of sizes to accommodate women with different body types. They are also available with a moderate or high profile, which is the amount of projection of the breast profile from back to front. Most round implants have a smooth surface because they can rotate after placement without causing any change in appearance or distorting the breast shape. However, they are available with a textured surface as well.
In 1999, the Institute of Medicine published the Safety of Silicone Breast Implants (1999) study that reported no evidence that saline-filled and silicone-gel filled breast implant devices caused systemic health problems; that their use posed no new health or safety risks; and that local complications are “the primary safety issue with silicone breast implants”, in distinguishing among routine and local medical complications and systemic health concerns.”
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".
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.
