Fat transfer or fat injection is known by various names, of which the commonly used are fat transfer, fat injection, and autologous fat graft. The word autologous means material (fat) is harvested from one area and donated to another in the same individual. Fat transfer has become essential in cosmetic facial surgery. Fat transfer is particularly suited for restructuring the proportion of the face. Typical facial structures can also be aided by adding constructive elements to correct a broad range of perceived facial deficiencies. For example, a stronger jawline creates a youthful, more powerful-looking face; eliminating the hollowness of lower lids helps reduce that tired, sad appearance; and fuller lips create a more youthful, attractive appearance. Fat transfer is also used for augmenting body contours, such as the breasts or buttocks. A simple analogy to understand the benefits of fat injection is looking at a whole and a ripe grape that becomes prune-like (wrinkled, puckered) over a period like a convex, youthful face that undergoes contraction and involution with age. Rather than remove what appears to be excess tissue and transform that raisin into a pea, perhaps it would be better to re-inflate that tiny raisin back into a grape. The minimally invasive technique using Fat transfer has become a standard procedure in facial rejuvenation. Fat injection is simple, inexpensive, permanent, and permanent. Other indications include congenital, traumatic defects, or surgical defects and scars. Fat injection meets all the fundamental criteria of ideal augmentation materials: availability, low antigenicity, minimal donor morbidity, reproducible, predictable results, avoids non-auto graft disease transmission or incompatibility, not likely to elicit an immune response, last reported complications, and longer survivability. Fat transfer provides a very appealing resource for soft tissue volume augmentation in small and large volumes. Other areas where fat injection techniques are considered superior to synthetic fillers in terms of the total amount required to perform more substantial aesthetic corrections include the buttocks and breasts. Prof. Moawad and many others insist on the dynamic, unique quality of fat as it will age as we age. This exceptional fat quality is perfect for soft tissue augmentation since facial structure changes as we age, and a permanent filler will be out of proportion if used.
The Disputes about longevity and the technique variation have postponed the announcement of fat as the perfect filler, added Prof. Moawad. Furthermore, fashion and trends change, and what is accepted now as beautiful maybe not be accepted later. Best of all, fat injections are forgivable, while the mistake of permanent filler is permanent!!! ” Prof Moawad says. The only relative drawback of fat injection has been the resorption of some of the fat transfer. However, with proper technique, approximately 30–70% of the fat is retained, Prof Moawad says.
