Assessing the prevalence of paranasal sinuses anatomical variants in patients with sinusitis using Cone Beam Computer Tomography.

Background And Aims: To asses, by using the Cone Beam CT (CBCT) reformatted images, the presence of anatomical variants of the sinonasal cavities and to determine the correlation of these variations with the onset of maxillary sinus inflammations.

Method: The study is a retrospective one and consists of the investigation of 130 patients with CBCT imaging, patients that were referred to the Maxillo-Facial Clinic, Radiology Department of the Iuliu Hatieganu University of Medicine and Pharmacy in Cluj-Napoca, for clinical symptoms of sinusitis within a period of 24 months. The images were analyzed for the presence of different anatomical variations and sinus inflammation.
