PREDILECTION OF SITE IN CHRONIC RHINOSINUSITIS: TOMOGRAPHIC FINDINGS IN 100 PATIENTS

AC Jyothi, BH Shrikrishna, Sandeep Samson, Sameena kokab, Sree Kantha.

Abstract
OBJECTIVE:To study the pattern of mucosal involvement in chronic rhinosinusitis using
computed tomography of 100 patients.
DESIGN:A prospective study of mucosal involvement of paranasal sinus region was done on
100 computed tomography scans of patients with chronic rhinosinusitis.
RESULTS: The most common site of involvement was osteomeatal complex followed by
maxillary antrum. This was followed by anterior ethmoids, posterior ethmoida, frontal sinus and
sphenoid sinus, in that order.
CONCLUSION:Osteomeatal complex is the most common site to get involved in chronic
rhinosinusitis. The blockade in the osteomeatal complex subsequently leads to impaired drainage
and inflammation in maxillary, ethmoid and frontal sinuses. Removal of disease in Osteomeatal
complex region is the basic principle of Functional Endoscopic Sinus Surgery which is best
appreciated on CT scan.

Key words: chronic rhinosinusitis, tomography, site prediliction
