Is it possible to tell if I have a deviated septum from pictures? (photos)

A septoplasty is performed for a deviated septum which is caused from cartilage and bone blocking airflow through the nose. This is performed for medical necessity and does not change the shape of the nose. A deviated septum can only be diagnosed with an internal examination of the noseSinus surgery is performed  to clean polyps and infectious material from inside the sinuses that cause repetitive sinus infections. This is also performed for medical necessity. A rhinoplasty is performed to change the shape of the nose, such as narrowing the bridge,  reducing the bulbous tip, and removing a dorsal hump.

The nasal septum is one of the inside the nose supporting structures. Changing a deviated septum close to the tip will change the position of the tip. Your nose looks pretty straight so fixing the deviated septum won't change the shape much but could help you breathe better.

From the external photos it is hard to tell for sure but your description is absolutely suspect for a septal deviation.  An internal exam is critical, however, as our septum is approximately 7cm long from front to back and 3-4 from top to bottom.  A broad area that requires evaluation prior to surgery to make sure the diagnosis is accurate.  Often the entire region needs to be assessed and addressed to correct all of your issues.  It behooves you to consider a consultation with a specialist that is double board certified in both ENT and plastic surgery to address all of your concerns.
