Thank you for the pictures. Your facial symmetry to your poorly reduced and now healed condyle fracture. This can be remedied with orthodontics and corrective jaw surgery. I would seek treatment by an orthodontist and the plastic surgeon or oral and maxillofacial surgeon.
You have opening deviation because the vertical height on your right jaw is shorter due to condylar collapse from an unrepaired fracture. To really repair that you would need a costochondral graft to restore vertical height on that side. Given that your only symptom is jaw deviation on opening, the risks from any operation for improvement (neck scar, infection, graft harvest) are probably not worth it.
Absolutely. You would probably need to remove the screws, reposition the jaws and place the hardware back again. Not that difficult.
