Is 9 cc' s a conservative amount for fat transfer to cheeks and under eyes?

Thank you for your questions. The amount of fat needed to treat areas depends on your specific face. Fat grafting is an excellent way to add volume and fill any defects that may be present but every patient is different in requirements of fat. If you are unsure, I recommend getting a second opinion with a board certified Plastic Surgeon who has experience in fat grafting. They will be able to assess your specific anatomy and help form a plan. In our office we offer 3D imaging to give our patients an accurate idea of what their final result will look like. Good luck!

It depends, as always.  A severe negative vector may not be corrected with fat as it is soft and may does not provide the structural support.  With a slight vector, fat can make all the difference and I generally would use 3 - 4 cc per side and get about 80% take.  The more fat with less take runs the risk of lumps or cysts from non-take.  A surgeon familiar with fat grafting should be able to examine you and know what is needed.  Ask to see some pics of "similarly vectored" patients.  Hope that helps!Dr. Z
