Just thought I'd start a thread here about fat grafting since it would help offset irregularities from jaw surgery. Specifically it can be used to augment orbital rim/malar area. Now there's a bit of controversy here. Some say it immediately absorbs, but actually fat is a living tissue and if it is harvested and grafted in the proper way it should actually last forever (or at least 10 plus years). Schendel apparently does it.

Fat grafting in general is very iffy especially for the orbital rim. theres many issues. first and foremost imo its highly overused. Per MissJ fat is really a permanenet filler for plumping, or best when you already have the bone structure or "shelf" to put the fat on. if you don't have the structure or shelf then really implants are the only option. I know you probably sont like them, honestly I don't either but if you have a orbital rim structure issue theres no other option other than a lefort 3 which no one will do on you because the risks are huge. there no shortage of people who really need orbital rim and got fat there and are unhappy.
also fat grafting in general is iffy. you have no clue how much will stay , how it will change over time,. when I saw heonig he told me he's seen many cases where someone gets fat graphs and looks good but then over time the grafts grow (like belly fat normally does as you age ) then you look terrible and its very hard to get out. also there's a debate whether most of the fat injected is dead on injection anyway since its put through the centrifuge, and this explains the hard cysts.
if I was going to do fat I'd do the dr. seckel style fat grafting. he takes a sliver of fat shapes it to form then inserts it. very little damage to the graft.
