rhinosinusitis

Rhinosinusitis is a simultaneous infection of the nasal mucosa (rhinitis) and an infection of the mucosa of the paranasal sinuses (sinusitis). A distinction is made between acute rhinosinusitis and chronic rhinosinusitis.

== Background == Because sinusitis typically is preceded by an infection of the nasal mucosa, some authors suggest generally replacing the term “sinusitis” with “rhinosinusitis”. The functional unity of the two mucosa speaks in favor of this replacement. A distinction is made between acute and chronic rhinosinusitis. Acute sinusitis lasts a maximum of 12 weeks. The clinical symptoms of acute rhinosinusitis are purulent nasal secretion, nasal obstruction and/or tension headache or feeling of fullness in the facial area. Acute rhinosinusitis can be caused by a viral or bacterial infection – a distinction is not possible during the first days. If the clinical picture follows a two-stage development, it indicates a bacterial rhinosinusitis. Chronic rhinosinusitis lasts more than 12 weeks with no complete recovery. The symptoms of chronic rhinosinusitis are less prominent/pronounced than of acute rhinosinusitis. Chronic rhinosinusitis is characterized/shaped by an impaired nasal inspiration, feelings of pressure and swelling in the facial area, as well as a higher susceptibility to infection.
