This typically outpatient procedure performed in the nostrils is the primary method for straightening a misaligned or deviated nasal septum, which septoplasty can repair without changing the appearance of the nose.

A deviated septum involves displacement of the cartilage wall that divides the nose’s nasal passages, potentially leading to difficulty breathing, nosebleeds, chronic sinus infections, and other problems. It can be caused by a congenital condition or injury.
