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.
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.
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.
Your medical history. The most important question your doctor will ask you is about your motivation for surgery and your goals. Your doctor will also ask questions about your medical history — including a history of nasal obstruction, surgeries and any medications you take. If you have a bleeding disorder, such as hemophilia, you may not be a candidate for rhinoplasty.
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.
Complications after breast lifts are relatively rare. The main three are bleeding, infection, and scarring. Your surgeon will give you instructions for preparing that will help lower your risk of complications. Those instructions will include such things as not smoking, making sure you are off medications that may make bleeding more likely, and taking antibiotics if necessary.
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.
