A Brazilian Butt Lift (BBL) is a cosmetic procedure that improves the appearance of the buttocks by augmenting their size and shape, in addition to removing fat from other parts of the body. During the procedure, a surgeon removes fat from areas such as the abdomen, flanks, thighs, or back using liposuction. The extracted fat is then purified and injected into specific points on the buttocks to achieve the desired shape and size. The procedure is also known as "buttock augmentation with fat grafting" or "safe subcutaneous buttock augmentation (SSBA)". It is important to note that a BBL is not a "lift" procedure, as it does not try to raise the buttocks but rather increases their volume. The procedure is typically suitable for individuals with good to moderate skin elasticity and adequate fat to accomplish the transfers.

A BBL is a two-step procedure that involves liposuction and fat grafting. The recovery period is similar to liposuction, and patients should expect to wear a compression garment and experience mild to moderate pain, bruising, and swelling. The key to a successful BBL recovery is to avoid sitting for too long. The results of a BBL can last for years and even more than a decade, but maintaining a healthy weight can help the results last.

It is important to note that a BBL can be risky and even fatal, but it is considered safer than other procedures to change the appearance of the buttocks. The procedure carries inherent risks, and unsafe techniques can be especially dangerous. The most serious potential complication is pulmonary fat embolism (PFE), which can be life-threatening. To minimize patient risks, cosmetic surgeons should use safe techniques, such as injecting fat no deeper than the subcutaneous plane, or directly beneath the skin. Surgeons can significantly minimize BBL risks by adhering to these safety guidelines[[5]](https://www.americanboardco...
