The shells of both saline and silicone gel breast implants are made of silicone elastomer (rubber), and the surface area is either smooth or textured. The main purpose of textured implants is to promote tissue adherence to the irregular surface and hold them into place. Therefore, a textured surface is used with contoured implants because they have a top and bottom, and rotation or movement distorts the breast shape. On the other hand, most round implants have a smooth surface because the breast shape is not affected if the implant rotates in the breast pocket.

Silicone gel filled breast implants consist of a silicone elastomer (rubber) shell pre-filled with a cohesive, gelatin-like substance that holds together uniformly while still retaining the natural give of breast tissue. Silicone gel breast implants are available in a wide range of sizes to accommodate women with different body types and aesthetic goals. Projections from moderate to high provide you with choices for the amount of projection of the breast silhouette.
The study Safety and Effectiveness of Mentor’s MemoryGel Implants at 6 Years (2009), which was a branch study of the U.S. FDA's core clinical trials for primary breast augmentation surgery patients, reported low device-rupture rates of 1.1 per cent at 6-years post-implantation.[49] The first series of MRI evaluations of the silicone breast implants with thick filler-gel reported a device-rupture rate of 1 percent, or less, at the median 6-year device-age.[50] Statistically, the manual examination (palpation) of the woman is inadequate for accurately evaluating if a breast implant has ruptured. The study, The Diagnosis of Silicone Breast implant Rupture: Clinical Findings Compared with Findings at Magnetic Resonance Imaging (2005), reported that, in asymptomatic patients, only 30 per cent of the ruptured breast implants are accurately palpated and detected by an experienced plastic surgeon, whereas MRI examinations accurately detected 86 per cent of breast implant ruptures.[51] Therefore, the U.S. FDA recommended scheduled MRI examinations, as silent-rupture screenings, beginning at the 3-year-mark post-implantation, and then every two years, thereafter.[22] Nonetheless, beyond the U.S., the medical establishments of other nations have not endorsed routine MRI screening, and, in its stead, proposed that such a radiologic examination be reserved for two purposes: (i) for the woman with a suspected breast implant rupture; and (ii) for the confirmation of mammographic and ultrasonic studies that indicate the presence of a ruptured breast implant.[52]

It is important for patients considering rhinoplasty to understand that if their nose requires repair due to congenital malformation, illness or injury, at least part of the operation is likely to be covered by insurance. This includes situations like sports injuries, vehicular accidents, or birth defects that result in breathing problems. In most cases of cosmetic surgery, however, performed only to improve the patient’s appearance, the patient should expect to pay out-of-pocket. 

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.[112] 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.[88]
the third technological development was the double lumen breast implant device, a double-cavity prosthesis composed of a silicone breast implant contained within a saline breast implant. The two-fold, technical goal was: (i) the cosmetic benefits of silicone-gel (the inner lumen) enclosed in saline solution (the outer lumen); (ii) a breast implant device the volume of which is post-operatively adjustable. Nevertheless, the more complex design of the double-lumen breast implant suffered a device-failure rate greater than that of single-lumen breast implants. The contemporary versions of second-generation breast implant devices (presented in 1984) are the "Becker Expandable" models of breast implant, which are primarily used for breast reconstruction.
In 2000, the FDA approved saline breast implant Premarket Approval Applications (PMA) containing the type and rate data of the local medical complications experienced by the breast surgery patients.[116] "Despite complications experienced by some women, the majority of those women still in the Inamed Corporation and Mentor Corporation studies, after three years, reported being satisfied with their implants."[113] The premarket approvals were granted for breast augmentation, for women at least 18 years old, and for women requiring breast reconstruction.[117][118]
You will find many different answers depending on who your ask. Cost will vary depending on many factors.... first of all it differs depending on if a board certified plastic surgeon is performing the surgery or not. Also, if the surgery is performed in a hospital based operating room vs. an office setting, if a board certified anesthesiologist is involved vs. a nurse (or sometimes performing... READ MORE
Does the nipple/areola sit below the crease underneath my breast? One trait cosmetic surgeons frequently look for when evaluating a breast lift candidate is the position of the nipple/areola in relation to the inframammary fold, or crease beneath the breast. Try this test: slide a plain sheet of paper underneath your breast (no bra) so it sits against the breast crease. When looking in the mirror, do your nipples sit below the top edge of the paper? If so, this is a good indication that you have enough sagging to warrant a breast lift. 

Breast reduction involves reducing the size of the breast. A breast lift involves lifting the nipple-areolar complex and reducing the excess skin of the breast. Breast reductions can involve just liposuction in patients who have more fatty tissue than glandular breast tissue. Liposuction alone indeed does reduce the volume of the breasts. However, sagging of the breast can result and liposuction alone is therefore performed usually in highly selected patients.
