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.
Implants come in various sizes, and your surgeon will guide you on choosing the right size to help you achieve the look you desire. In addition, your surgeon will help you decide whether you want a more natural, teardrop shape or a more rounded look. Implants also come with either smooth our textured shell surfaces, and your surgeon will help you decide which is best for you.

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.[93]

Case 47: This patient’s primary surgery left her with valve collapse, nostril notching, persistent tip rounding and hanging columella. Secondary surgery involved correction of these issues with repositioning and reconstruction of the tip cartilages to improve tip contour. Although she is still a little swollen in the after photos, she is already happy with her new nose.
the second technological development was a polyurethane foam coating for the shell of the breast implant; the coating reduced the incidence of capsular contracture, by causing an inflammatory reaction that impeded the formation of a capsule of fibrous collagen tissue around the breast implant. Nevertheless, despite that prophylactic measure, the medical use of polyurethane-coated breast implants was briefly discontinued, because of the potential health-risk posed by 2,4-toluenediamine (TDA), a carcinogenic by-product of the chemical breakdown of the polyurethane foam coating of the breast implant.[92]

2. You buttock's structural anatomy is also an important factor.  A V-shaped buttock typically requires more fat transfer to achieve a satisfactory improvement than an A-shaped buttock.  Transferred fat cells need to grow their own blood supply from the surrounding buttock tissues in order to survive.  In order for this to happen, the transferred fat cells need to be gently interwoven between your buttocks' living cells to survive.  Therefore, each person's buttocks can only receive a certain amount of fat, and exceeding that amount will not be effective.  A generous amount of fat is typically transferred at the time of surgery, knowing that some of the fat will go away during the recovery period.

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.
Case 43: Rhinoplasty in this pretty professional woman was all about removing the bump she had hated for years and correcting the tip droop and asymmetry that had worsened with age. Relatively small changes here have created a real sense of refinement while maintaining her long, elegant profile. A lower face and neck lift along with facial fat transfer helped to round out the enhancements in her already beautiful appearance.
When compared to the results achieved with a silicone-gel breast implant, the saline implant can yield acceptable results, of increased breast-size, smoother hemisphere-contour, and realistic texture; yet, it is likelier to cause cosmetic problems, such as the rippling and the wrinkling of the breast-envelope skin, accelerated lower breast pole stretch, and technical problems, such as the presence of the implant being noticeable to the eye and to the touch. The occurrence of such cosmetic problems is likelier in the case of the woman with very little breast tissue, and in the case of the woman who requires post-mastectomy breast reconstruction; thus, the silicone-gel implant is the technically superior prosthetic device for breast augmentation, and for breast reconstruction. In the case of the woman with much breast tissue, for whom sub-muscular emplacement is the recommended surgical approach, saline breast implants can produce an aesthetic result much like that afforded by silicone breast implants, albeit with greater implant palpability.[90]

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.

These placements vary from shallow (subglandular) to deep (complete submuscular). The right placement for your breast implants is based on your anatomy as well as your goals and expectations. You should express your desires to your surgeon, but make sure to take his or her expert opinion into account. Improper implant placement can create complications such as breast augmentation double bubble, wrinkles and rippling.

Case 89: This patient had broken her nose with consequent severe loss of tip support, tip rounding, crookedness, and a traumatic bump. In this case, a lateral crural overlay technique was used to reduce and lift the tip along with a septal extension to help with support and straightening which has improved tremendously as seen on the base view. Even though she’s still swollen in these early photos, she already has a great result and it’s only going to get better.
Firstly about surgical technique. Breast lift and reduction employ similar surgical technique, it's just that with reduction you're removing more breast tissue (because the biggest aim of a reduction is.... to reduce the size of the breast). Does breast lift remove SOME breast tissue, the answer is yes, but the AIM of the lift is more to restore the youthfulness of the breast. Both women, one wanting a reduction vs a lift need their nipple/areolar complex repositioned "up". Only the woman wanting a reduction need the volume addressed.
In 2008, the longitudinal study Excess Mortality from Suicide and other External Causes of Death Among Women with Cosmetic Breast Implants (2007), reported that women who sought breast implants are almost 3 times as likely to commit suicide as are women who have not sought breast implants. Compared to the standard suicide-rate for women of the general populace, the suicide-rate for women with augmented breasts remained constant until 10-years post-implantation, yet, it increased to 4.5 times greater at the 11-year mark, and so remained until the 19-year mark, when it increased to 6 times greater at 20-years post-implantation. Moreover, additional to the suicide-risk, women with breast implants also faced a trebled death-risk from alcoholism and the abuse of prescription and recreational drugs.[12][13] Although seven studies have statistically connected a woman's breast augmentation to a greater suicide-rate, the research indicates that breast augmentation surgery does not increase the death rate; and that, in the first instance, it is the psychopathologically-inclined woman who is more likely to undergo a breast augmentation procedure.[14][15][16][17][18][19]
In the past, concerns emerged that silicone implants posed health risks, including an increased risk of systemic diseases such as lupus and arthritis. The Food and Drug Administration (FDA) placed a moratorium on silicone implants in 1992 so the safety of these devices could be studied. However, in 2006 the agency concluded that there was no evidence of risk and lifted the moratorium.

There are two main types of implants for you to consider: saline and silicone. Most people say the silicone implants feel and look more natural than saline, but they cost more. Silicone implants are typically about $1,000 more than saline, but if you’re interested in gummy bear implants—a type of silicone implant—expect to pay even more. In a RealSelf Q&A, Omaha, Nebraska plastic surgeon Dr. Richard J. Bruneteau says you should expect to pay “about $500 more than standard silicone implants.”
In the early 1990s, the national health ministries of the listed countries reviewed the pertinent studies for causal links among silicone-gel breast implants and systemic and auto-immune diseases. The collective conclusion is that there is no evidence establishing a causal connection between the implantation of silicone breast implants and either type of disease. The Danish study Long-term Health Status of Danish Women with Silicone Breast Implants (2004) reported that women who had breast implants for an average of 19 years were no more likely to report an excessive number of rheumatic disease symptoms than would the women of the control group.[26] The follow-up study Mortality Rates Among Augmentation Mammoplasty Patients: An Update (2006) reported a decreased standardized mortality ratio and an increased risk of lung cancer death among breast implant patients, than among patients for other types of plastic surgery; the mortality rate differences were attributed to tobacco smoking.[27] The study Mortality Among Canadian Women with Cosmetic Breast Implants (2006), about some 25,000 women with breast implants, reported a 43 per cent lower rate of breast cancer among them than among the general populace, and a lower-than-average risk of cancer.[28]

Case 44: One of the hardest things to accomplish in a nose job is giving a person a smaller version of the same nose. In Los Angeles, where small differences can mean everything, doing Finesse Rhinoplasty is common. Even at 6 months, you can see that, on profile, this patient’s tip is less projected but he still has a strong masculine profile. On base view, you will also notice the deprojection and the fact that alar base reduction can be done with no visible scars and maintenance of the natural nostril curve.
The current lifetime risk of BIA-ALCL in the U.S. is unknown, but estimates have ranged between estimated to be between 1 in 70,000 to 1 in 500,000 women with breast implants according to MD Anderson.[73] Certain geographic locations have demonstrated variable risks. For instance, a December 2016 update from the Therapeutic Goods Administration of Australia and New Zealand reported a risk of 1:1,000 to 1:10,000 for textured implants.".[71] To date (2017), there has not been a case of BIAL reported where the patient had only implantation of smooth shell breast implants or a textured tissue expander that was exchanged for a smooth implant. The paucity of cases reported in Asian populations has raised the possibility that there may be a range of genetic susceptibility to the phenomena, or alternatively merely reflect differences in how cases are identified and reported.
