Role Of Multidetector Ct In Radiologiacal Evaluation Of Paranasal Sinuses In Patients With Chronic Rhinosinusitis

Abstract

Introduction : Chronic rhinosinusitis (CRS), with or without nasal polyps, is characterized by the inflammation of the nose and 
paranasal sinuses. To make the diagnosis of CRS, a patient must exhibit 2 or more of the following symptoms for at least 12 
weeks time period: nasal obstruction, nasal blockage, or congestion, and/or nasal discharge (which could be anterior or posterior 
nasal drip), along with possible facial pain or pressure, and/or a reduction or loss of smell. This diagnosis must be supported by 
observable disease signs, which can be identified through an endoscopic examination showing nasal polyps, mucopurulent 
discharge, or edema/mucosal obstruction.
