Location
- Nasal cavity - rhinitis
- Paranasal sinuses - sinusitis
- Guttural pouch and eustachian tube - eustachitis
- Pharynx - pharyngitis
- Trachea - tracheitis
- Bronchi - bronchitis
- Bronchioles - bronchiolitis
- Lungs - pneumonia/pneumonitis
- Pleura - pleuritis/pleurisy
Type
Grossly many inflammatory processes (eg: response to viral or bacterial infection) in the URT will begin as a serous discharge, and then progress to a catarrhal exudate, and then to purulent/pseudomembranous/haemorrhagic as neutrophils are recruited
- Serous - transparent fluid exudate (acute inflammation)
- Catarrhal - mucous exudation (acute to subacute inflammation)
- Pseudomembranaous - fibrin exudation
- Purulent - pus
- Ulcerative
- Haemorrhagic
- Granulomatous (chronic inflammation)
- Polypoid (chronic inflammation)
Timecourse
- Acute
- Subacute
- Chronic
