Rasvansiirrot

Rasvansiirrot, also known as fat grafting or fat transfer, is a cosmetic surgical procedure where fat is taken from one part of the body and injected into another. The primary goal is to enhance volume, contour, or rejuvenate areas. Common donor sites for fat harvesting include the abdomen, thighs, and buttocks. The harvested fat is then processed, typically by centrifugation or filtration, to purify it before injection.

The procedure can be used to address a variety of aesthetic concerns. In facial rejuvenation, it can restore lost volume in areas like the cheeks, temples, and under-eye hollows, leading to a more youthful appearance. It is also frequently used for breast augmentation, offering a natural-looking alternative to implants, and for buttock augmentation, to improve shape and volume. Additionally, fat grafting can be employed to correct contour irregularities, such as those resulting from liposuction, and to improve the appearance of scars and certain types of tissue defects.

The fat is injected using fine needles or cannulas into the target area. A portion of the transferred fat is expected to be reabsorbed by the body, so surgeons often overcorrect slightly to account for this. The survival rate of the grafted fat depends on various factors, including the injection technique, the health of the recipient site, and the patient's overall health. The procedure is generally considered safe, with risks similar to other surgical interventions, including infection, bleeding, and uneven results. Recovery time varies depending on the extent of the procedure and the areas treated.
