The shape and size of my nose are fine. But in profile, the septum seems to hang down so you can see inside my nostril. Is there a specific procedure to cut this portion off or is that rhinoplasty?
Rhinoplasty is the term for any procedure done to change the appearance of the nose. It can be limited to certain spots (nostril show, profile alteration, tip narrowing) or encompass complete change of all areas of the nose.
