Abstract
Objective: To study the frequency and types of anatomical variants of osteomeatal complex on Computed Tomography scan in clinically diagnosed chronic sinusitis patients.

Materials and Methods: A prospective study was done on 100 patients with chronic sinusitis over a period of 18 months.

Results: In our study anatomical variations in osteomeatal complex were seen in 77% of chronic sinusitis cases. Out of which 62.3% of the cases had 2 or more anatomical variations whereas 37.7% of the cases had single anatomical variation. Deviated nasal septum (85.7%) was found to be the most common anatomical variation followed by concha bullosa (45.4%). Least common anatomical variation seen was haller cell (2.6%).

Conclusion: The presence of anatomical variations in osteomeatal complex is high in chronic sinusitis patients which is best appreciated on CT scan, which has become a widely accepted tool for assessing these variations in a much simpler way and acts as a roadmap for endoscopic sinus surgery.
