Evaluation of the Frequency of Anatomic Variations of the Paranasal Sinus Region by Using Multidetector Computed Tomography: A Hospital-Based Cross-Sectional Study.

Background And Aims: The sinus anatomy should be well-understood by the sinus surgeons to carry out functional endoscopic sinus surgery carefully. That's why CT scans are vital to provide essential clarity and accuracy for comprehensive presurgical planning with minimal risks. The aim of this study was to evaluate the frequency of anatomic variations of the paranasal sinus region by using multidetector computed tomography.
