The fat grafting procedure may be divided into three separate phases: fat harvesting, fat processing, and fat injection into recipient sites . When speaking of fat harvesting, we refer to the surgical procedure which permits us to obtain adipose tissue through the use of suction cannulas or, rarely, through en bloc surgical excision of fat. Processing techniques involve centrifugation, filtration, Telfa rolling, and cleansing of the fat to remove anaesthesia, oil, blood, and other components in the harvested adipose tissue. Injection techniques differ much, depending on the selection of different syringes and cannulas or needles for injection of the fat into the recipient area. Within each phase of fat grafting, there are many variations in techniques and numerous discussions in favour of one rather thn another. It is mandatory to construct an optimal procedure from start to finish.
