Summary

This study looks at how jaw surgery changes not just your bite and appearance, but also your emotions, jaw muscles, and joint health. Researchers will follow 100 patients before and after surgery, using scans, muscle tests, and questionnaires to track these changes. The goal is to better understand what leads to a successful recovery and higher patient satisfaction.
