Abstract
Background: Paranasal sinuses are a group of four paired airfilled, mucosa lined spaces surrounding the nasal cavity. Thepneumatization or hypoplasia of the sinuses affects thedrainage pathways, causing chronic infections andcomplications. The aim of the present study was to assess theanatomical variations of paranasal sinuses on computedtomography.Materials and Methods: The present retrospective study wascarried out over the period of 6 months using 80 CBCT imagesof patients, with their age group ranging from 20-50 yearsreferred for different oral diagnostic purposes. An assessmentof paranasal sinuses and it’s variations were accuratelycharacterized in axial, coronal and sagittal sections. The datawas analysed statistically using SPSS 21 software and Chisquare test was used to find the statistical significance.Results: In the present study total participant were 80 in which56.25% were having anatomical variation. 8.75% were havingvariation in agar nasi cells,10% were having variation in Kuhncells, 7.5% were having variation in Onodi cells, 5% werehaving variation in haller cells, 10% were having variation inconcha bullosa, 12.5% were having variation in nasal septumdeviation, 20% were having variation in maxillary sinus septa,17.5% were having variation in sphenoid sinus pnematization,2.5% were having variation in maxillary sinus pnematization,6.25% were having variation in Crista galli pneumatisation.Conclusion: This study concluded that imaging of the PNS willaid in diagnosis in individual patients, and also provide adeeper understanding of the manifestations of the disease.
