Having trouble pinpointing what is causing this - What are common ways to fix nose asymmetry? (photos)

Thank you for providing images along with your question. While you already appear to have an attractive profile based on your photos, asymmetries are better assessed during a proper evaluation. I recommend scheduling an in-person consultation with a reputable board-certified facial plastic surgeon. Such experts will have the optimal skills, as well as artistry and knowledge of facial aesthetics, harmony, and proportion, helping you achieve the most natural-looking results. During your consultation, your surgeon will evaluate your skin and facial profile, discuss your concerns and goals, recommend the best procedure(s), and ensure the best possible outcome.

Unfortunately, these are not good photos to give you any meaningful advise about rhinoplasty. In person consultation with a board certified plastic surgeon, expert in rhinoplasty, possibly 3D simulation would help to clarify your problem and solution. Good luck.

On the left side there is a mild raised area. It is inconsequential and is not effecting the beauty of your nose. I would recommend to leave it alone.
