Deviated septum
A shift of the wall between the nostrils that can block airflow, cause congestion, and sometimes bend the outside of the nose. Correcting it is often combined with cosmetic reshaping.
What It Is
A deviated septum is a structural shift in the wall (septum) that divides the two nostrils. This misalignment can range from minor to severe and may occur from birth or develop after an injury. When significant, it can narrow one or both nasal passages, leading to breathing difficulties, chronic nasal congestion, or sleep disruption. The deviation can also affect the outward appearance of the nose. Many people with a deviated septum have no symptoms, while others experience noticeable functional or cosmetic concerns.
