How does Heights Plastic Surgery perform facial fat grafting? January 25, 2023 Before your facial fat grafting surgery begins, a local or topical anesthetic will be administered to your treated areas. This is to ensure you are as comfortable and pain-free as possible throughout the entirety of your procedure. Fat grafting involves removing fat from the thighs or abdomen and putting into regions on the face that are starting to lose fat. Only a small amount of fat is removed, so this procedure should not be equated with liposuction. The harvested fat will then be injected into the areas using blunt, hollow needles called cannulas. Because Dr. Downey and Dr. Bullocks uses a micro-droplet technique, more blood will circulate to the grafted fat, giving it a higher chance of surviving and holding its volume post-surgery.
