I have long face syndrome. What are the ways in which I can achieve the best possible results? (Photo)

My face length was normal few years ago. I have a very long face now . I used to mouth breathe a lot . Some people tell me that i also have a weak chin. What are the best possible ways to correct or improve these features. My face looks thin and long . Could my face length be restored to what it was before (Photo attached). Iam willing to use invasive methods . Just want to know if these methods might accidentally lead to more deformation.(The photo with aviators is the before photo) Thank you
