Fat injection, also known as fat grafting or fat transfer, can be used to restore depleted tissue volumes or to surgically enhance and enlarge the appearance of facial features. It is a simple, yet powerful technique, to transfer viable, living fat cells from one region of a patients body to another. Although most widely performed for facial work, fat grafts can be employed in almost any region of the body. The grafts are layered into the recipient area so that they are throughout the tissues rather than in a isolated grouping. This has the effect of making the enhancement appear very natural and not “fatty”. When performed correctly the transformation is dramatic and permanent.
It is however not a technique designed for the transfer of large volumes of fat (e.g. for buttock augmentation), rather it is used for more subtle enhancement of features and correction of depressions. Previous attempts to use fat transfers to achieve a large volume changes prove to be unsuccessful for many reasons.
An initial result is obvious at the completion of surgery, the final result however is not seen for at least 3-6 weeks.
