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) [66] concludes that "any claims that remain regarding an association between cosmetic breast implants and CTDs are not supported by the scientific literature".
For the second 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!

Some costs for breast implant revision surgery may be covered by your surgeon, depending on the reason for revision. “Generally, if the doctor feels the result is below their expectations, they will often cover much or all of the cost,” says Seattle plastic surgeon Dr. Richard P. Rand in a RealSelf Q&A. “However, if the problem is something about your body, like capsular contracture or wrinkling and rippling above the muscle, it is reasonable that charges should apply as this is no fault of the doctor.”

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.

Dr. Larry Fan is a Harvard educated, Board Certified Plastic Surgeon in San Francisco, CA. He is a Master Artist who is known for creating beautiful, stunning, and natural results. Dr. Fan has been named One of America's Top Plastic Surgeons for the past 10 years running and has received several national awards for his work in Plastic Surgery. He has successfully performed more than 10,000 cosmetic procedures of the face, breasts, and body over a 20 year period. Dr Fan has been an invited speaker at the American Society of Plastic Surgeons and the American College of Surgeons, and has been featured in national media outlets such as CNN, NBC, and ABC.
Dr. Mess typically harvests fat from the abdomen through a tiny incision in the belly button using state-of-the-art cannulas specifically designed to create small particle size for greater accuracy and for maximal fat cell viability. If the patient does not have adequate abdominal fat she may harvest from the thighs, love handles or other sites. The fat will be placed in a centrifuge where the fat will be separated from fluids and non-essential elements. The fat will then be transferred to the recipient site using precisely placed injections on multiple plains to achieve the structure and look you desire. On the day of the procedure, donor and graft sites will be laid out and marked following the plan designed during your consultation.  Dr. Mess uses markers to map the surgery and distinguish between donor and recipient sites.
Subfascial: the breast implant is emplaced beneath the fascia of the pectoralis major muscle; the subfascial position is a variant of the subglandular position for the breast implant.[77] The technical advantages of the subfascial implant-pocket technique are debated; proponent surgeons report that the layer of fascial tissue provides greater implant coverage and better sustains its position.[78]
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.[74]
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.
