Useful information for patients on Fat Transfer (Body) procedures - enhancing the face and body using fat collected from another area of the body.
Body fat transfer, also known as fat grafting or lipofilling, is a surgical technique that uses a patient’s own fat to restore volume, improve contour, correct asymmetry, or enhance selected areas of the body.
Fat is first removed from a donor area using liposuction. Common donor areas include the abdomen, waist, back, or thighs. The harvested fat is then carefully processed and transferred into the desired treatment area using specialized cannulas.
Fat is placed strategically in small amounts throughout the recipient tissues to maximize contact with the surrounding blood supply. A portion of the transferred fat establishes a permanent blood supply and becomes living tissue in its new location, while another portion is naturally reabsorbed during healing.
Because fat retention varies between patients and treatment areas, the result cannot be predicted using one universal percentage. Additional fat grafting may occasionally be recommended to achieve or maintain the desired contour.
Body fat grafting may be used to:
The amount of fat that can safely and effectively be transferred depends on the treatment area, available donor fat, tissue quality, anatomy, and the patient’s goals.
Body fat transfer may be appropriate for patients who:
Very thin patients may not have sufficient donor fat to achieve their desired degree of augmentation.
Before surgery, patients typically undergo a detailed medical history and physical examination.
Preparation may include:
Specific fasting and medication instructions will be provided by the surgical and anesthesia team.
Ensure you consider all aspects of a procedure. You can speak to your surgeon about these areas of the surgery in more detail during a consultation.
How Long Is the Procedure?
Operative time varies considerably depending on the amount of liposuction required, the volume of fat transferred, the number of treatment areas, and whether fat grafting is combined with another procedure.
Do I Need Anesthesia?
Small-volume procedures may occasionally be performed with local anesthesia and sedation. More extensive fat transfer is commonly performed under general anesthesia.
Is The Procedure Inpatient or Outpatient?
Most isolated fat-transfer procedures can be performed on an outpatient basis in appropriately selected patients. More extensive or combined procedures may require additional postoperative monitoring.
Patients should expect healing in both the donor and recipient areas.
Donor Areas
Fat-Grafted Areas
Temporary effects may include:
Some grafted areas may initially appear fuller than the eventual result because of swelling and because a portion of the transferred fat will naturally be reabsorbed.
Potential risks include:
Certain risks vary significantly according to the area being treated. Fat grafting to the breasts, for example, may result in fat necrosis, cysts, or calcifications that can affect future breast imaging.
Gluteal fat grafting, commonly referred to as a Brazilian Butt Lift or BBL, has additional and potentially serious safety considerations. Fat embolism associated with gluteal fat grafting can be life-threatening or fatal. Current multisociety safety recommendations support placement of fat only within the subcutaneous tissues above the gluteal fascia and the use of real-time ultrasound guidance to visualize the injection cannula during fat placement.
Patients considering gluteal fat grafting should discuss the surgeon’s technique, facility accreditation, safety protocols, and use of ultrasound guidance during consultation.
Recovery depends on both the amount of liposuction performed and the location and volume of fat transferred.
Patients are encouraged to begin gentle walking shortly after surgery to promote circulation and reduce the risk of blood clots.
Compression garments may be recommended over liposuction donor areas to help manage swelling and support the tissues during healing.
Pressure on the fat-grafted area may need to be limited during the early healing period depending on the treatment location. Specific positioning and activity instructions vary considerably according to where fat has been transferred and should be followed carefully.
Many patients can return to light daily activities within several days and desk-based work within approximately one to two weeks, although more extensive procedures may require additional recovery time.
Strenuous exercise and heavy lifting are gradually resumed according to the surgeon’s instructions.
Swelling improves progressively over several weeks, but residual swelling and tissue changes may continue for several months.
Fat transfer can improve:
Some improvement is visible immediately after surgery, but the early appearance reflects both transferred fat and postoperative swelling.
During the following weeks and months, swelling decreases and a portion of the transferred fat is naturally reabsorbed. The fat that successfully establishes a blood supply becomes living tissue within the recipient area.
The result is generally assessed after the tissues have settled over several months rather than during the early postoperative period.
Additional fat grafting may occasionally be recommended if more volume or contour refinement is desired.
Fat that survives transplantation can provide long-lasting improvement. However, transferred fat remains responsive to changes in body weight. Significant weight gain may enlarge the grafted fat cells, while significant weight loss may reduce their volume. Maintaining a stable weight helps preserve the surgical result.
Individual results vary according to the treatment area, amount of fat transferred, anatomy, blood supply, surgical technique, weight stability, and healing characteristics. Consultation with a board-certified plastic surgeon is necessary to determine whether fat transfer is appropriate and what degree of correction can reasonably be achieved.
