- Abstract
Stenosis of the ostiomeatal complex, from either the anatomical configuration or hypertrophied mucosa can cause
obstruction and stagnation of secretions that may then become infected or perpetuate infection. The surgical
interventions of the functional endoscopic sinus surgery are designed to remove the ostiomeatal blockage and to
restore normal sinus ventilation and mucociliary function. Hence, the present study was taken up to study the variations
in the ostiomeatal complex and its clinical significance. For CT analysis coronal sections of 40 paranasal sinus CT films
were collected from the department of ENT. Lateral deviation of the uncinate process was more common with equal
incidence in both sexes and with higher incidence on right side. Nasal septum was deviated to the right side more
commonly with equal incidence in both sexes. Nearly half of the cases showed agger nasi with higher frequency in
males. Concha bullosa was the least common ostiomeatal variant with higher incidence in males with equal incidence
on both sides. Preoperative planning for FESS requires high resolution computed tomography (CT) to provide detailed
maps, which are used for navigation and the visualization of the anatomical variants that result in sinus disease. As a
result, it has become imperative for radiologist and clinicians to improve understanding of ostiomeatal unit.
