Abstract

The prevalence of anatomic variations has been variously described, ranging from pure anatomic descriptions to descriptions based on CT examinations. These variations compromise already narrow drainage pathways and produce significant obstruction. CT examination of PNS will provide an anatomic road map of the PNS to identify the presence of significant anatomic abnormalities, the locations and severity of the disease and exact location of the obstruction. All the patients who satisfied the inclusion criteria of the study were subjected to history taking and physical examination to identify clinical signs at presentation. Then the patients were subjected to CT scan of nose and paranasal sinus region and the anatomy of the sinonasal region was thoroughly assessed after a probable diagnosis was made. There was no significant difference in Association between Anatomical Variations of Sinus and Age distribution. In the present study there was a significant difference in Association between Agger Nasi Cells (p value-0.030), Paradoxical Curvature (p value- 0.024), Haller cells (p value-0.045) and Frontoethmoidal Cell Variations-Type 1 (p value- 0.048) and Sex distribution. In the present study aggernasi cells were more commonly seen in males and paradoxical middle turbinate and type I frontoethmoidal cell variation were found to be more common in females
