A BBL is a surgical procedure, and the key surgical parts should be performed by the surgeon. This includes the surgical plan, liposuction, fat processing decisions, and fat injection. Nurses and other trained staff can have important roles in the operating room, anesthesia support, positioning, preparation, monitoring, and postoperative care, but they should not be independently performing the surgeon’s operation. The exact legal scope of practice can vary by state or country, and some tasks may be delegated under direct physician supervision depending on local regulations. Even so, the patient should know who is doing each part of the procedure before surgery. It is reasonable to ask directly: “Will you personally perform my liposuction and fat grafting?” and “What parts, if any, are delegated to assistants?” For BBL, this matters because safe fat placement is critical. Choose a board-certified plastic surgeon who is transparent about the operative team, operates in an accredited facility, and follows current BBL safety protocols, including avoiding fat injection into the muscle.
