Deciding how much fat to transfer to a patient’s buttocks is a decision made by the surgeon that takes safety, cosmetic result, and patient’s goals into account. I recommend reviewing your goals of surgery, by showing photos, or performing Vectra imaging in office, with your surgeon and listening to their recommendations for the safest, best-looking results possible.
Breast reconstruction with fat grafting: If you have breast defects following lumpectomy for breast cancer, fat grafting is an effective method for filling in these defects. Fat grafting is also an option for total breast reconstruction following mastectomy; however, to achieve sufficient breast volume, this is usually a multistage process that requires at least two to four sequential fat grafting procedures.
Because a breast implant is a Class III medical device of limited product-life, the principal rupture-rate factors are its age and design; Nonetheless, a breast implant device can retain its mechanical integrity for decades in a woman's body. When a saline breast implant ruptures, leaks, and empties, it quickly deflates, and thus can be readily explanted (surgically removed). The follow-up report, Natrelle Saline-filled Breast Implants: a Prospective 10-year Study (2009) indicated rupture-deflation rates of 3–5 per cent at 3-years post-implantation, and 7–10 per cent rupture-deflation rates at 10-years post-implantation.
Breast implants are not lifetime devices and breast implantation may not be a one-time surgery. The most common complications for breast augmentation and reconstruction with MemoryGel® Implants include any reoperation, capsular contracture, and implant removal with or without replacement. The most common complications with MemoryShape® Implants for breast augmentation include reoperation for any reason, implant removal with or without replacement, and ptosis. The most common complications with MemoryShape® Implants for breast reconstruction include reoperation for any reason, implant removal with or without replacement, and capsular contracture. A lower risk of complication is rupture. The health consequences of a ruptured silicone gel breast implant have not been fully established. MRI screenings are recommended three years after initial implant surgery and then every two years after to detect silent rupture. The most common complications with MENTOR® Saline-filled Implants include reoperation, implant removal, capsular contracture, breast pain, and implant deflation.
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.
Sucking fat from your hips and thighs and injecting it into your boobs or butt may seem like a dream come true—and for some, it is. The process, called fat transfer or fat grafting, involves removing fat from one part of the body via a gentle liposuction, and then injecting it elsewhere. It works well all over the body, but is most commonly used on the face to enhance cheeks, fill hollow lower eyelids, and build up areas that have lost volume due to aging, explains New Jersey plastic surgeon Parham Ganchi, M.D. It’s also commonly used to plump up butts and to increase breast size and improve breast shape.
Inframammary: an incision made to the inframammary fold (natural crease under your breast), which affords maximal access for precise dissection of the tissues and emplacement of the breast implants. It is the preferred surgical technique for emplacing silicone-gel implants, because it better exposes the breast tissue–pectoralis muscle interface; yet, IMF implantation can produce thicker, slightly more visible surgical scars.
The saline breast implant—filled with saline solution (biological-concentration salt water 0.90% w/v of NaCl, ca. 300 mOsm/L.)—was first manufactured by the Laboratoires Arion company, in France, and was introduced for use as a prosthetic medical device in 1964. The contemporary models of saline breast implant are manufactured with thicker, room-temperature vulcanized (RTV) shells made of a silicone elastomer. The study In vitro Deflation of Pre-filled Saline Breast Implants (2006) reported that the rates of deflation (filler leakage) of the pre-filled saline breast implant made it a second-choice prosthesis for corrective breast surgery. Nonetheless, in the 1990s, the saline breast implant was the prosthesis most common device used for breast augmentation surgery in the United States, because of the U.S. FDA's restriction against the implantation of silicone-filled breast implants outside of clinical studies. Saline breast implants have enjoyed little popularity in the rest of the world, possessing negligible market share.
Unfortunately, as time goes on it is often difficult for patients to remember the specifics of the type of breast augmentation surgery and implants that they had. Your are not alone! The easiest way to determine what type of implant you had is to request a copy of the operative report from either the hospital, surgery center or your surgeon's office. The implant specifics are recorded on this document. Your office record also includes this information. If it has been over ten years since your procedure, sometimes these records are no longer available. Ultrasound or MRI can help to answer this question but it is an expensive way to solve the mystery and not an indication for these procedures. If you registered your implants with the manufacturer at the time of surgery, the company will have a record of this information. Fortunately, this inforation is not absoltely critical to your health unless you are having a problem with your implants. Your surgeon can often develop a reasonable treatment plan even without this information. I would strongly recommend that you register your implants and purchase the affordable insurance program if you have surgery again. These programs are helpful in storing vital information regarding your implant type, size, filler, model and lot number. Should there be a recall or long term problem requiring additional surgery, this information is readily available. There is often also some fiancial support to offset costs. Investigate the options available by contacting your surgeon or the implant manufacturer's websites.
