Aim: To assess variations in sinuses using CT scans. Methodology: One hundred ten subjects with sinonasal symptoms were selected in this prospective, observational study. All patients were subjected to CT scan and were examined for the presence of haller cell, pneumatisation in the nasal septum, onodi cell, paradoxical middle turbinate, superior and middle turbinate, uncinate process and deviated nasal septum (DNS). Results: Out of 110 patients, males were 62 and females were 48. Special cells such as agger nasi cells were seen in 65 patients, haller’s cells in 20 and onodi cells in 25 patients. The difference was significant (P < 0.05). Frontal sinus shows septations in 35, maxillary sinus in 24, sphenoid sinus in 12 and ethmoid sinus in 16 patients. The difference was significant (P < 0.05). Frontal sinus hypoplasia was seen in 6 cases, maxillary sinus in 3, ethmoid sinus in 2 and sphenoid sinus in 4. The difference was significant (P < 0.05). Horizontal uncinate process was seen in 65 and vertical uncinate process was seen in 45 cases. The difference was significant (P < 0.05). Common variation such as deviated nasal septum was observed in 57 and concha bullosa in 21 cases. The difference was significant (P < 0.05). Conclusion: Careful analysis of sinuses before undergoing sinus surgery is required for achieving best results and preventing further complications. CT scan is useful in assessment of variation in para- nasal sinuses.
