Can I reverse my fat graft + orthodontic and extraction of 4 teeth + lower sunken mid face to chin? What can I do?

your situation is far too complex to get an accurate answer on a post on real self.  You need to start with the fundamentals which is your facial a skeletal structure and dental health. Will you be getting implants?  I would avoid any short-term fix or soft tissue work until bony and dental structures have been adequately addressed and corrected. At that point seek the help of the most talented and experienced plastic surgeon you can find and create a working plan. Don't rush into any procedures until you have a definitive plan of action. Especially rhinoplasty revisions! Best, Mats Hagstrom M.D.
