What is fat grafting?
Fat grafting is a procedure in which fat is harvested by liposuction from a part of the body where it is unwanted and then transferred or grafted by injecting it into an area where it can be used to add volume, fill a dimple or groove, or correct a contour deformity. Advantages to fat grafting include using your own fatty tissues rather than a foreign body injectable and the added benefit of having liposuction remove fat from an area where you don’t want it. Also, your fat will last longer than injectable fillers, which will only last months to years before reinjection is required to maintain their benefits.
Fat injections can be done under local or IV sedation anesthesia. Using thin cannulas, fat is harvested from the hip, inner or outer thigh, lower back, or lower abdomen. These areas are called the ‘donor sites‘. The fat is then decanted and processed in a special centrifuge, and is then injected into the desired facial area. The area where the fat is re-injected is called the ‘recipient site‘. When performed properly, a large percentage of the fat transfer will ‘take’ and the face will fill out to look more youthful.
