Radiological Evidence of Frequency of Involvement of Paranasal Sinuses in Chronic Rhinosinusitis

Abstract

This study is aimed to find out the frequency of involvement of various paranasal sinuses in Chronic Rhinosinusitis. Hundred adult patients with Chronic Rhinosinusitis were selected. . All selected patients underwent non-contrast coronal and axial CT scanning of paranasal sinuses. Involvement of various paranasal sinuses in CT images of all patients recorded. Out of total 100 patients, 52 were males and 48 females. Patients were in the age range of 18 and 65 years. Maxillary sinus was involved in 99% cases, Anterior Ethmoid in 89% cases, Frontal sinus in 64% cases, Posterior Ethmoid Sinus in 61% cases and Sphenoid sinus in 31% cases. The most involved sinus was Maxillary sinus and the least involved was Sphenoid sinus. When multiple sinuses were involved, the most common combination was Maxillary, Anterior Ethmoidal, Posterior Ethmoid and Frontal sinuses in 50 patients, followed by Maxillary, Anterior Ethmoid, Posterior Ethmoid, Frontal and Sphenoid sinusitis in 26 cases and Maxillary and Anterior Ethmoid sinusitis in 19 cases. Isolated maxillary sinus is seen in 17 cases, isolated Frontal sinusitis in 3 cases and isolated Sphenoid sinus in 2 cases. Maxillary sinus is the most commonly involved paranasal sinus in Chronic Rhinosinusitis and sphenoid sinus least involved.
