A deviated nasal septum, or also known as DNS, is common physical disorder of the nose which involves the displacement of the nasal septum. This disorder is often caused by impact trauma, or force or blow to the facial area near the nose.
On the other hand, deviated nasal septum can also be a congenital disorder, which means that you acquire DNS from childbirth. This may happen when there was a compression of the nose during pregnancy or childbirth.
