How do I know if I need cheekbone reduction or jaw surgery?

How can I determine whether I need cheekbone reduction or jaw surgery to achieve a more balanced facial structure? What are the key differences between these procedures, and how can I identify which one would address my specific concerns, such as prominent cheekbones, a wide mid-face, or a square or asymmetrical jawline? Are there any non-surgical options for evaluating my facial structure, such as 3D imaging or professional consultations, that can help me make an informed decision before committing to surgery?
