Buccal fat removal and transfer of the fat.

I am getting buccal fat removal done and my surgeon has never transfered the buccal fat anywhere but searched online where one surgeon had done it. Has anyone else ever done this? Would the germs on the buccal fat from the mouth be able to be sterilized enough to kill all the germs before injection into the face? I'm wanting to get it injected in lips, scars and maybe under eyes.
