From the first half of the twentieth century, physicians used other substances as breast implant fillers—ivory, glass balls, ground rubber, ox cartilage, Terylene wool, gutta-percha, Dicora, polyethylene chips, Ivalon (polyvinyl alcohol—formaldehyde polymer sponge), a polyethylene sac with Ivalon, polyether foam sponge (Etheron), polyethylene tape (Polystan) strips wound into a ball, polyester (polyurethane foam sponge) Silastic rubber, and teflon-silicone prostheses.
Post-operative patient surveys about mental health and quality-of-life, reported improved physical health, physical appearance, social life, self-confidence, self-esteem, and satisfactory sexual functioning. Furthermore, the women reported long-term satisfaction with their breast implant outcomes; some despite having suffered medical complications that required surgical revision, either corrective or aesthetic. Likewise, in Denmark, 8 per cent of breast augmentation patients had a pre-operative history of psychiatric hospitalization.
While more experienced surgeons may charge more for their expertise, that’s not always the case. “You should not choose a qualified surgeon based on high fees any more than you should choose one based on low fees,” says Boca Raton, Florida plastic surgeon Dr. Hilton Becker in a RealSelf Q&A. “The most important factors should be education, experience, certification, and your ability to feel comfortable with your surgeon.”
For the second part....it depends where your butt is starting at. There is a point in which there is too much pressure in the butt that no more fat can really be injected. Pressure kills the fat cells (which is why you cannot sit on the butt for a few weeks after surgery). It also means that we cannot just keep injecting if the gluteus has fully expanded and is not able to take any more. If you are starting with a small butt.....there is a smaller limit. If you are starting with a medium sized butt.....there is a bigger limit. I like to use power assisted "vibration expansion filling" to really push the boundaries of how much fat can be injected into the buttocks. This helps to expand the buttocks on the table and get more fat into more stubborn areas. Typically, even for smaller girls, I will inject at least 1000ml per side (and up to 1600ml for larger girls). After this, as you have probably read, 30-50% of the fat will either reabsorb or "not take". However, with the removal of a large amount of fat around your midsection combined with careful technique and contouring of the butt and hips, we can make a very large difference in your overall proportion. Best of luck to you!
The amount of good quality, transferrable fat will depend on how much can be retrieved from the donor sites. This can be partially estimated after examination (the surgeon inspects and pinches the areas of potential fat harvest to get an idea of how much fat can realistically be harvested), but it is hard to know for sure until the procedure is well underway. Abdominal and love handle/flank fat tend to be the best sources because the fat is more easily retrieved and softer than back fat, but the back is also routinely liposuctioned in the BBL procedure to both obtain extra tissue for transfer and to improve the 360 degree shaping of the torso. I have transferred anywhere from 300cc per buttock to over 1200 in some patients, depending on the circumstances.
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.
