What should I do when my jaw on the right side is longer & seem to be pushing my entire jaw including my chin to one side? photo

The right side seem to be a lot longer than the length of my left side. My chin is off the centre, almost as if the longer jaw grew so that it pushed my chin to one side. Whenever I yawn, or open my mouth wide, my jaw on the longer side pops out sorta like it's dislocating. It's a very uncomfortable feeling and sometimes it really hurts. I would like to know what I could do to fix it, and if surgery is the only option, then what kind of procedures and what kinds of incisions would be made?
