Deviated Nasal Septum (DNS)

A deviated nasal septum (DNS) is one that is deflected laterally from the mid line of the nose. The deviation usually occurs at the junction of bone with the septal cartilage. 

A DNS may occur as a result of a developmental abnormality or trauma. 

If the deviation is severe, it may entirely block the nasal passageway. Even a partial blockage may lead to infection.

If inflammation occurs, it may cause nasal congestion, blockage of the para-nasal sinus openings, chronic sinusitis, headache and nosebleeds
