Liposuction revision - can fat grating be performed in the chin/neck area to restore lost volume?

I had liposuction performed to my under chin/neck area 2 years ago. Way too much fat was taken out and i have been left with an undesired result. Can fat grafting be performed in this area to restore lost volume? I am only interested in fat grafting under the jawline. Any help with this would be appreciated. Located in Wollongong. Thanks, Chris
