Fat graft is the ideal autologous filler material. Coupled with liposuction fat grafting enables contour restoration with patients self tissues. It is ideal for many aesthetic and reconstructive purposes as follows:
Fat grafting has many advantages including injectability therefore eliminating the risk of incision scar and restoration of tissue microenvironment thus softening the tissue and improving skin quality (thanks to many mesenchymal precursors and growth factors in the fat graft). The main disadvantage is the resorption rate (30 to 40 percent volume stays inside after 6 months). So this main disadvantage leads to the need for 2-3 sessions of grating depending on the target area. As another solution fat grafts can be stored in sub-zero temperatures for months with success enabling sequential injections without harvesting. Ideal donor areas are lower abdomen and buttocks for fat harvesting via liposuction cannulas.
If you feel that you need contour refinement and soft tissue insufficiency on any part of your body and have the patience for 2-3 sessions of minor surgery; you are a good candidate.
Fat grafting is a safe, satisfactory procedure (after multisessions) and undesired results are few. Infection, tissue reaction and aseptic necrosis can be encountered. These are rare and treatable complications. For periorbital injections central retinal artery occlusion which may lead to visual impairment is the only risk and its extremely rare.
