Structural fat grafting can be performed for filling sunken hollows under eyes , to fill sunken cheeks, to correct hollowed eyelids, and is often used for blepharoplasty correction when too much skin and or fat has been removed in an eyelid surgical procedure.
Structural fat grafting is a procedure in which small amounts (less than 0.1 cc at a time) of fat are carefully microinjected in a series of discrete layers to gradually 'build' new soft tissue structure. As there is space between each microinjection, new blood vessels are able to grow into the grafted fat, allowing it to persist. If this process of blood vessel ingrowth (neovascularization) does not occur, then the injected tissue cannot truly be considered a 'graft' and is instead just another 'soft tissue filler' of limited duration.
Fat Grafting requires specialized training and specialized surgical instruments, as well as patience and attention to detail on the part of the surgeon. When performed properly, permanent improvements are possible.
