Abstract

Introduction This study aims to evaluate the presence and characteristics of anatomic variations and mucosal abnormalities of the paranasal sinus in patients with chronic rhinosinusitis by coronal plane Computed Tomography (CT) scan imaging. Materials and Methods This retrospective descriptive study constituted a study population of 100 patients with clinical evidence of chronic rhinosinusitis with or without nasal polyposis. All patients were evaluated with Computed Tomography (CT) imaging of Paranasal sinus coronal view. The study duration was from July 2011 to September 2014. Result The most common anatomic variation found was Deviated Nasal Septum (DNS) (74%) followed by Concha Bullosa (48%). Maxillary sinus was found to be the most commonly exposed to mucosal abnormalities. Patients with grade I, II and III polyposis had mean CT scan Lund-Mackay scores of 14, 17.2 and 22 respectively. Patients without polyposis had least mean CT scan score of 10. Conclusion Computed Tomography of the paranasal sinus has improved the visualization of paranasal sinus anatomy and has allowed greater accuracy in evaluating paranasal sinus disease. Deviated nasal septum and concha bullosa were the most common variations in the nose and paranasal sinuses and are proposed to play a significant role in the causation of Chronic Rhino Sinusitis (CRS).
