Anatomical variations of paranasal sinus detected by computed tomography

33012

Aim. Anatomic variations of the sinonasal region are commonly seen in people. Recently, the developments in paranasal sinus surgery increased the need for detailed knowledge of the anatomy and pathology of this region. Computed tomography (CT) is a research method that shows the anatomy and pathology of the paranasal sinus at the highest level. Method. In this study, the aim was to determine the frequency of anatomical variations of sinonasal region by reviewing the coronal section CT scans of 1008 patients admitted to Cumhuriyet University, The Ear Nose and Throat Clinic between January 1999 and January 2009 retrospectively Results. The analysis of the 1008 patients’ CT scans revealed that mucosal changes were present in 645 patients (64%; Group 1), the remaining 363 patients (36%, Group 2) had no mucosal changes. When all of the cases in this study were examined in terms of anatomical variations, there were no significant differences between Group 1 and group 2 regarding pterygoid process pneumatization, anterior clinoid pneumatization and septum pneumatization (p 0.05). There were significant differences between the groups regarding all anatomic variations outside of the above-mentioned cases (p 0.05). Sinusitis were present in 548 (67.7%) of 809 variation-positive cases, whereas 261 (%32.3) of 809 variation-positive cases did not have sinusitis. Conclusion. There are not definite results in the literature about the prevalence of anatomical variations of paranasal sinuses. We believe that the differences of the results of this retrospective study conducted on a large sample arise from the genetic, gender and racial differences as well as evaluation of only coronal section CT scans
