DNS or deviated nasal septum refers to a condition in which the nasal septum separating the two halves of the nose is deviated. It can lead to a number of symptoms including nose block, headache , nasal discharge , mouth breathing , snoring, bad breath, dry mouth , reccurent throat pain etc. Treatment depends on the severity and symptoms and may be medical or surgical. Surgical treatment is called septoplasty and is now being increasingly done endoscopically.
