What are the associations among paranasal imaging results, symptoms, bony anatomic variations, and culture-proven bacterial acute rhinosinusitis (ARS)?
Bottom Line: Paranasal mucosal abnormalities and osteomeatal complex (OMC) obstruction do not develop gradually during ARS but are present when symptoms begin and remain fairly constant in most patients both with and without bacterial ARS.

Background: ARS is a common condition, but its pathophysiology and the development of bacterial ARS are not yet completely known. Pathophysiology has earlier been evaluated with radiologic imaging, but systematic sequential imaging of the paranasal sinuses of the same patients during a single ARS episode would provide more information on ARS pathophysiology.
Study design: Inception cohort study with 50 conscripts with ARS diagnosed between February 1 and April 15, 2012.
