Abstract
This article reviews the pathophysiology and the clinical and imaging diagnosis of rhinosinusal inflammations.
Chronic sinusitis usually develops after an incompletely treated acute sinusitis.
Complications occur through fungal superinfection, osteomyelitis, extension of the inflammatory process in the orbit or adjacent meningoencephalic structures.
The imaging investigation is indicated as the symptoms get worse, for the elucidation of sinus contents, for establishing the therapeutic protocol, for identifying and finding solutions to solve nearby complications.
