A deviated nasal septum is often present with a curved nose. If you have obstructive symptoms, this may be the case. A direct examination of the septum is the only way to diagnose the deviation.
This could be true but the best way to find out is an in person examination. Usually the surgeon can look inside of your nose and tell if you have a deviated septum. Please see a board certified plastic surgeon for evaluation and to discuss options for your surgery if needed.
