I had a chin reduction a year ago, and now I regret it. Can it be reversed? (Photo)

Hello, A year ago I had a chin reduction combined with rhinoplasty, I don't like my new chin I prefer my old one. I had my chin mandibular reduced with fracture of bone ( osteotomy) with incision inside the mouth just under the teeth. I now have a metal plate with screws in place.I do not like the esthetic outcome,my chin is now too flat,before it was a little protruding with more definition which was more appealing and manly. My question is how can i reverse this and get my old chin back? thx
