Chronic Rhinosinusitis

Rhinosinusitis is an inflammation of the sinonasal mucosa that leads to sinonasal symptomatology such as congestion, mucopurulent drainage, facial pain/pressure and reduced sense of smell.

From the standpoint of pathophysiology, Rhinosinusitis is a multifactorial process without one specific underlying etiologic process. Symptoms lasting for more than 12 weeks make a diagnosis of Chronic Rhinosinusitis that can be associated with diminished general health-related Quality of Life.
Treatment can be either medical or surgical (FESS) depending on the information that clinical (nasal endoscopy) and radiological (CT scan) investigations will provide.
