If I am considering jaw contouring, where should I start looking?

I'm looking into jawline contouring because I'm concerned about both my jawline and facial asymmetry.

However, it's difficult because I heard that jawline contouring isn't just about face shape; they also need to consider the bite.

It's hard for a layperson to tell if my face can be treated with contouring alone or if I actually need jaw surgery.

If my mouth doesn't align properly or if my jaw feels misaligned, should I consider orthodontics as well?

What is the best order to approach this research to avoid confusion?
