Chronic sinusitis: sinusitis which persists for longer than 12 weeks.
Runny nose is excess drainage, which may range from a clear fluid to thick mucus, produced by the nasal and adjacent tissues and blood vessels in the nose. The drainage of runny nose may run out of your nose or down the back of your throat or both.
Rhinorrhoea refers to a thin, relatively clear nasal discharge. Rhinitis refers to inflammation of the nasal tissues from a number of causes, which usually results in a runny nose.
Nasal congestion may or may not accompany runny nose
- Runny nose can be caused by anything that irritates or inflames the nasal tissues. Infections such as the common cold,allergies and various irritants may all cause a runny nose. Some people have a chronically runny nose for no apparent reason — a condition called non-allergic rhinitis or vasomotor rhinitis (VMR).
- Sinusitis means sinus inflammation. Most sinusitis attacks are caused by an infection. Sinusitis is said to be acute if it lasts from 4-30 days and sub-acute if it lasts from 4-12 weeks. A minor acute sinusitis attack is common and many people will have some sinusitis with a cold. A few people have periodic acute sinusitis attacks.
- A diagnostic nasal endoscopy( DNE) with a good case history will reveal most causes of the nasal disease.
CT scan of the paranasal sinuses ( PNS) is reserved for difficult to diagnose cases or before surgery ( as a road map to the extend of disease).
- Medical management works in most cases . If not, surgery can be considered.
