Background and objective: Several studies have shown that anatomical variations of the osteomeatal unit of nose predispose to sinusitis. Hence this study was aimed to know the various anatomical variations of the osteomeatal unit of the nose using computed tomography.
Materials and Methods: A prospective study was done on 200 computed tomography scans of patients visiting ENT OPD for evaluation of headache.
Results: The different anatomical variations observed in our study were concha bullosa, paradoxical middle turbinate, retroverted uncinate process, enlarged ethmoid bulla, haller cells, agger nasi cells, onodi cells and pneumatisation of vomer. The most frequent anatomical variation found was presence of concha bullosa (22%).
Conclusion: Variations are common in the osteomeatal unit of the nose. These variations may predispose to paranasal sinus diseases. Also, awareness of these variations helps the otorhinolaryngologist and/or radiologist to evaluate the CT scans of paranasal sinuses better. This will, in turn, help in endoscopic examination as well as in surgery.
KEY WORDS: Paranasal Sinuses, Anatomic Variation, Tomography, Concha Bullosa, Turbinates.
