ABSTRACT: Objective: The aim of the present study was to evaluate the structural
variations of nasal cavity in reference to frequency and types
at the key area i.e. the ostiomeatal
complex. Materials and Methods: Computed tomography of Paranasal sinuses of 50 patients was studied for clinical suspicion of various sinonasal pathologies. Results: The most commonly encountered
anatomical variations in this study were Deviated Nasal Septum in 78% (39
patients), followed by Concha Bullosa in 36% (18 patients), Agger Nasi cell in
18% (nine patients), Pneumatised septum in 12% (six patients), Paradoxical
Middle Turbinate and Septated Maxillary Sinus in 10% (five patients each) and
Pneumatised Uncinate Process 6% (three patients). In quite a few patients we
witnessed more than one variation. Conclusion: The anatomical variations in the nose and ostiomeatal complex are not
uncommon, with the most frequent ones involving the nasal septum and the middle
turbinate.
