What is a deviated septum?

Also known as: nasal septum deviation, deviated nasal septum, DNS.

The nostrils and two nasal passages within the nose are separated by a thin wall called the nasal septum. When this septum is out of place, it can make one nasal passage smaller and cause nasal congestion with difficulty breathing. This is known as deviated septum.
