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!
Furthermore, The Effect of Study design Biases on the Diagnostic Accuracy of Magnetic Resonance Imaging for Detecting Silicone Breast Implant Ruptures: a Meta-analysis (2011) reported that the breast-screening MRIs of asymptomatic women might overestimate the incidence of breast implant rupture.[53] In the event, the U.S. Food and Drug Administration emphasised that “breast implants are not lifetime devices. The longer a woman has silicone gel-filled breast implants, the more likely she is to experience complications.”[54]

The Cronin–Gerow Implant, prosthesis model 1963, was a silicone rubber envelope-sac, shaped like a teardrop, which was filled with viscous silicone-gel. To reduce the rotation of the emplaced breast implant upon the chest wall, the model 1963 prosthesis was affixed to the implant pocket with a fastener-patch, made of Dacron material (Polyethylene terephthalate), which was attached to the rear of the breast implant shell.[91]

Case 29: Major concerns for this patient were widening of the tip with a marked lack of projection which made his nose feel flat and washed out. Nostril thickness and rounding was also something he wanted addressed. In this case, irradiated donor rib cartilage was used to project and support the tip along with alar base reduction removing a significant amount of nostril flare to create a natural tip and nostril contour that is ethnically appropriate. Fat transfer to the cheeks helps to balance out his flat mid-face to strengthen the cheek contour which can be seen nicely on the profile view.
Manufacturer’s warranty programs can mitigate some of the costs of treating complications. But, the warranty payment is only available if a rupture is detected. Some surgeons fail to inform their patients of the need for periodic MRIs, or downplay the FDA recommendation in order to make a sale. “Many women don’t know about the maintenance costs and potential expenses of silicone gel implants,” reports Dr. Ellen Mahony, board-certified plastic surgeon in Westport, CT.  “Because rupture with a silicone gel implant is ‘silent,’ it can go undetected for an extended period, often not becoming obvious until the process of capsular contraction has begun.” Capsular contraction leads to a more complex surgery. That means added surgical costs which your warranty may not cover.
The ‘gummy bear’ implant comes in both round and teardrop shapes. They have a firmer gel, which may give a better shape and may last longer. The round gummy bear implant is often a good choice for women with looser tissues and who want a more durable implant that remains soft. The teardrop shaped gummy bear implant may be a good choice for women whose tissues are relatively tight and desire a very proportionate and natural looking enhancement with less fullness of the upper portion of the breast and more projection and fullness of the lower portion of the breast.
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]
There are four general types of breast implants, defined by their filler material: saline solution, silicone gel, structured and composite filler. The saline implant has an elastomer silicone shell filled with sterile saline solution during surgery; the silicone implant has an elastomer silicone shell pre-filled with viscous silicone gel; structured implants use nested elastomer silicone shells and two saline filled lumen; and the alternative composition implants featured miscellaneous fillers, such as soy oil, polypropylene string, etc. Composite implants are typically not recommended for use anymore and, in fact, their use is banned in the United States and Europe due to associated health risks and complications.
Transaxillary: an incision made to the axilla (armpit), from which the dissection tunnels medially, to emplace the implants, either bluntly or with an endoscope (illuminated video microcamera), without producing visible scars on the breast proper; yet, it is likelier to produce inferior asymmetry of the implant-device position. Therefore, surgical revision of transaxillary emplaced breast implants usually requires either an IMF incision or a periareolar incision.
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.

The study Effect of Breast Augmentation Mammoplasty on Self-Esteem and Sexuality: A Quantitative Analysis (2007), reported that the women attributed their improved self image, self-esteem, and increased, satisfactory sexual functioning to having undergone breast augmentation; the cohort, aged 21–57 years, averaged post-operative self-esteem increases that ranged from 20.7 to 24.9 points on the 30-point Rosenberg self-esteem scale, which data supported the 78.6 per cent increase in the woman's libido, relative to her pre-operative level of libido.[20] Therefore, before agreeing to any surgery, the plastic surgeon evaluates and considers the woman's mental health to determine if breast implants can positively affect her self-esteem and sexual functioning.
The good news is that both types of implants are considered safe. The Food and Drug Administration (FDA) removed silicone implants from the consumer market in 1992 as a precautionary measure after conflicting reports of possible complications surfaced. Some of these complications required breast implant removal. However, silicone gel-filled breast implants were fully exonerated and reapproved in 2006. (Read more about implants and the FDA.)
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.
When the patient is unsatisfied with the outcome of the augmentation mammoplasty; or when technical or medical complications occur; or because of the breast implants’ limited product life, it is likely she might require replacing the breast implants. Common revision surgery indications include major and minor medical complications, capsular contracture, shell rupture, and device deflation.[44] Revision incidence rates were greater for breast reconstruction patients, because of the post-mastectomy changes to the soft-tissues and to the skin envelope of the breast, and to the anatomical borders of the breast, especially in women who received adjuvant external radiation therapy.[44] Moreover, besides breast reconstruction, breast cancer patients usually undergo revision surgery of the nipple-areola complex (NAC), and symmetry procedures upon the opposite breast, to create a bust of natural appearance, size, form, and feel. Carefully matching the type and size of the breast implants to the patient's pectoral soft-tissue characteristics reduces the incidence of revision surgery. Appropriate tissue matching, implant selection, and proper implantation technique, the re-operation rate was 3 percent at the 7-year-mark, compared with the re-operation rate of 20 per cent at the 3-year-mark, as reported by the U.S. Food and Drug Administration.[64][65]
Facial fat transfer: If you have facial creases, such as laugh lines, smile lines, and crow’s-feet, fat can be removed from your abdomen, thighs, or other areas and be injected into your face. Acne scars and sunken areas of the face, lips, and cheeks can also be filled in. Your plastic surgeon can even use grafted fat to minimize lines between your nose and mouth, correct skin depressions or indentations and minimize forehead wrinkles.
Dr. Mess performs fat transfer to the face to fill facial hollows and lines as a standalone procedure or in addition to neck lift or blepharoplasty. Fat transfer to the face is a more permanent and more natural alternative to fillers. Fat transfer to the hands can restore volume and provide a more youthful-looking hand. During your consultation, you will discuss your goals and expectations and review photographs to understand the plan.

Case 31: This patient had some typical concerns of feeling washed out from the front with flattening and spreading of her tip. She was very happy with the narrowing and definition achieved for her bridge and tip along with nostril reduction. In addition, chin augmentation increased chin projection to improve the balance of her lower face and jawline.
Periareolar: a border-line incision along the periphery of the areola, which provides an optimal approach when adjustments to the IMF position are required, or when a mastopexy (breast lift) is included to the primary mammoplasty procedure. In periareolar emplacement, the incision is around the medial-half (inferior half) of the areola's circumference. Silicone gel implants can be difficult to emplace via periareolar incision, because of the short, five-centimetre length (~ 5.0 cm) of the required access-incision. Aesthetically, because the scars are at the areola's border (periphery), they usually are less visible than the IMF-incision scars of women with light-pigment areolae; when compared to cutaneous-incision scars, the modified epithelia of the areolae are less prone to (raised) hypertrophic scars.
Cosmetic surgeons use a variety of incision techniques for breast lift surgery; the exact technique used will vary based on a patient’s existing breast tissue, the amount of excess skin to be removed, and her personal goals. Your cosmetic surgeon will recommend the type of breast lift that will achieve optimal results with the least conspicuous scarring possible.
Many different types of breast lifts are now available in conjunction with a breast reduction, including lifts just around the areola (periareolar), vertical/lollipop mastopexies (incision around the areola and down to the breast fold, and full breast lifts with an anchor incision. For patients who have very loose skin in the armpit or back, axillary or bra lifts are also often combined with breast reductions.
A curvature and droopy tip brings undue focus to this young man’s nose. Although there is still some swelling in these early post-operative photos, we can already see a nose that is now straight, has a smooth profile and no longer droops. A sense of length is preserved to match his oval face. More than that, because of these positive changes, he also looks younger.
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 time the procedure takes is also an important factor. The longer and more complicated the procedure, the more you can expect to pay for it. This is why a breast augmentation with fat transfer and a breast lift with implants cost more than a standard breast augmentation with implants. Some surgeons include their fee in the price they give you for your entire procedure. Be sure to ask during your consultation!
Great question!  Without seeing you it is difficult to make an accurate assessment.  However as a general rule, the maximum amount of liposuction that can be performed in an outpatient setting, is around 5 liters due to the vast amount of fluid shift.  After filtration of the fluid, blood, devitalized fat cells, and lipids, generally you are left with about 2 liters of mature viable fat for injection.  Which means 1 liter to each side - which is a lot.  Take into account that you will loose anywhere from 20-40% of the volume so now we are at about 600-800cc's that will remain...that is with a maximum of 5 liter of liposuction.  If you have more than 5 liters of fat, then you may need to undergo this procedure a second time in order to harvest more fat for injection.

Photographs. Someone from your doctor's office will take photographs of your nose from different angles. Your surgeon may use computer software to manipulate the photos to show you what kinds of results are possible. Your doctor will use these photos for before-and-after assessments, reference during surgery and long-term reviews. Most importantly, the photos permit a specific discussion about the goals of surgery.

When you're in the thick of the recovery, it seems like you're going to look and feel that way forever. But honestly, I moved through it so quickly. Days two and three were the toughest, but witnessing my body heal like that was pretty incredible. Each day, I looked considerably different from the day before, which is strange — you really can't get too attached to any one image in the mirror because you know it's still evolving.
Breast reduction surgery will take about two to five hours, sometimes longer. Your surgeon will make a cut around your nipple then downward on the breast in the form of a keyhole. The operating team will remove extra skin, tissue, and fat from your breasts and reposition your nipple. Your surgeon may use drainage tubes and then stitch up your breasts and wrap them in a special gauze. You may also need to wear a surgical bra.
Saline breast implants are filled with sterile saltwater. This implant type is recommended for women who do not wish to have silicone implants as well as some women who desire the 'Baywatch' look with a high degree of upper pole fullness and projection. In the right patient, saline implants can also look very natural. Saline implants are generally less popular today than silicone implants.
They are essentially very similar procedures. The difference is in the amount of breast tissue removed. In a breast lift procedure, the nipple areolar complex is lift to a better position on the breast, and some breast tissue is removed and the breast envelope tightened. In a breast reduction, the nipple areolar complex is also lifted, but much more breast tissue is removed. 
Fill Filled with a highly cohesive gel for durable shape retention designed to give a youthful feel. Filled with a proprietary cohesive gel that hold together uniformly while retaining the natural give that resembles breast tissue. Filled with a saltwater solution similar to the fluid that makes up most of the human body; slightly firmer feel than gel.
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]

Another option is to consider getting your breast implants at a teaching hospital from a learning resident. You won’t get the delicate skill of an experienced, board-certified surgeon, but teaching hospital residents are “assisted by established, experienced, private attending surgeons,” says Beverly Hills plastic surgeon Dr. Robin T.W. Yuan in a RealSelf Q&A.

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.
Case 61: The concerns in this case were crookedness and a significant breathing issue due to a severely deviated septum. She also felt her nose was over-projected and a little too big for her face. Here we can see resolution of her crooked septum on base view. The tip has been defined and de-projected and the bump brought down to create a naturally pretty and more balanced contour.

Of course, the breast reduction vs. breast lift question is not really cut and dry because every woman is unique. You may be unsure of what volume you would like with the breasts in a more favorable position. Breasts may be different sizes (asymmetric). The position of the nipple may be out of proportion to the amount of breast sag. Breasts may be ‘deflated’ after pregnancy. You may have heard that breast implants are the only reliable way to lift breasts. These questions can easily be addressed at the time of your consult.
Contoured implants, also called anatomical or teardrop-shaped implants, are shaped like a natural breast and create a sloped shape when placed over the chest muscles. Round breast implants have that, well, "round" Victoria's Secret or Playboy model shape. Contoured implants may flip over if the surgeon does not create the pocket correctly, resulting in a misshapen breast. Not true with round implants. If a round breast implant flips, it still looks the same. Your decision on implant shape should be based on how you want your new breasts to look.
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.[69] 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.[70] 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." [71] Diagnosis and treatment of breast implant associated ALCL now follows standardized guidelines established by the National Comprehensive Cancer Network.[72]
