Nerve Damage Risks with Jaw Surgery?

One side of my jaw slightly sticks out more than the other. I would like this corrected, it's only the very edge of my jaw that would need altered, just around where the jaw becomes angled. However, I am worried about nerve damage that could cause facial paralysis or noticeable problems with my mouth/lips. What nerve is it that if damaged could lead to the kind of problems I describe? And is it near where I would need the bone removed? Thanks
