Will jaw injury affect jaw growth? (Photo)

I had an accident when i was in primary school and I remember hearing a soft crack sound on my jaws. Now that i am 18 years old, i notice a slight assymetry where the left portion of my face is slanted. Would that injury had caused the assymetry problem or is it a biological factor ? I also have protruded upper jaw, dentist said i should get a maxillofacial surgery but he did not said anything about the asymmetry. Can i get both the protruded and asymmetry jaw fixed at the same time ?
