Deviated Nasal Septum

What is Deviated Nasal Septum?

A deviated septum occurs when the thin wall (nasal septum) between the nostrils is displaced to one side. The septum separates the right and left nasal cavities and ideally is situated in the center of your nose, equally separating the two sides. However, in many people, the nasal septum is displaced, making one nasal passage smaller.

When a deviated septum is severe, it can block one side of your nose and reduce airflow, causing difficulty breathing, nosebleeds and other symptoms.


Some people are born with a deviated septum.

Other people develop a deviated septum after injury or trauma to the nose.
