There are two types of breast implants approved by the Food and Drug Administration (FDA): silicone-filled and saline-filled. They come in various sizes and shapes, and with two types of shells: textured shells and smooth shells. A type of silicone-filled implant with a thicker filling, called a form-stable highly cohesive implant, or "gummy bear" breast implant, is currently under investigation and may one day provide another option for women undergoing breast augmentation with implants.
By the next day, I was looking more like a monster and didn't want to see anyone. The bruises around my eyes shined a bright greenish-purple, and I was swollen all over with some intense pressure in my head. I couldn't breathe through my nose anymore, because of all the blood and swelling. I felt congested and uncomfortable, almost like I had a bad cold, but again, nothing Tylenol couldn't handle. But I fully expected this, as Dr. Kolker said it could take two weeks for everything to run its course.
Dr. Rotemberg will examine the area of your body you would like to improve upon for muscle strength, skin elasticity, and fat loss, as well as the area in which she believes the fat should be transferred from. At this time, she will also ask you pertinent medical questions, and do a full exam, to make sure you are a good candidate for any procedure.
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.”
Since the mid-1990s, the fifth generation of silicone-gel breast implant is made of a high-strength, highly cohesive silicone gel that mostly eliminates the occurrences of filler leakage (“silicone gel bleed”) and of the migration of the silicone filler from the implant pocket to elsewhere in the woman's body. These implants are commonly referred to as "gummy bear breast implants" for their firm, pliant consistency, which is similar to gummy candies. The studies Experience with Anatomical Soft Cohesive Silicone gel Prosthesis in Cosmetic and Reconstructive Breast Implant Surgery (2004) and Cohesive Silicone gel Breast Implants in Aesthetic and Reconstructive Breast Surgery (2005) reported low incidence-rates of capsular contracture and of device-shell rupture; and greater rates of improved medical-safety and technical-efficacy than that of early generation breast implant devices.[94][95][96]
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.

The breast implant has no clinical bearing upon lumpectomy breast-conservation surgery for women who developed breast cancer after the implantation procedure, nor does the breast implant interfere with external beam radiation treatments (XRT); moreover, the post-treatment incidence of breast-tissue fibrosis is common, and thus a consequent increased rate of capsular contracture.[108] The study Breast Cancer Detection and Survival among Women with Cosmetic Breast Implants: Systematic Review and Meta-analysis of Observational Studies, reported an average later stage in the diagnoses of women who developed breast cancer after undergoing breast augmentation, when compared to breast cancer patients who had not undergone breast augmentation, although this did not ultimately affect the patients prognosis. The use of implants for breast reconstruction after breast cancer mastectomy appears to have no negative effect upon the incidence of cancer-related death.[105][109]
Saline-filled breast implants contain a silicone outer shell filled with a sterile saltwater (saline) solution. Some are pre-filled and others are filled during the implant operation. Saline-filled implants come in different sizes and have either smooth or textured shells. The FDA approved saline-filled breast implants for breast augmentation in women age 18 or older and for breast reconstruction in women of any age. They are also used in revision surgeries, which correct or improve the result of an original surgery.

The U.S. Food and Drug Administration established the age ranges for women seeking breast implants; for breast reconstruction, silicone-gel filled implants and saline-filled implants were approved for women of all ages; for breast augmentation, saline implants were approved for women 18 years of age and older; silicone implants were approved for women 22 years of age and older.[120] Because each breast implant device entails different medical risks, the minimum age of the patient for saline breast implants is different from the minimum age of the patient for silicone breast implants—because of the filler leakage and silent shell-rupture risks; thus, periodic MRI screening examinations are the recommended post-operative, follow-up therapy for the patient.[121] In other countries, in Europe and Oceania, the national health ministries' breast implant policies do not endorse periodic MRI screening of asymptomatic patients, but suggest palpation proper—with or without an ultrasonic screening—to be sufficient post-operative therapy for most patients.
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]
