[Topography of maxillary sinus septa according to cone beam computed tomography data]

The aim of the study was to establish the location, orientation and height of the maxillary sinus primary septa. The data of 100 cone-beam computed tomography scans of patients with a mean age of 37.6±15.4 years from dental outpatient hospitals of Minsk, Belarus taken from 2012 to 2019 were analyzed. The prevalence of sinus septa was 45.6% for sinuses and 37.2% for patients. As a rule, septa were symmetric bilaterally. The heights of septa varied from 2-3 mm to 8-14 mm in the majority of cases. Orientation of septa was coronal in 94.7%, sagittal in 3.9%, and horizontal in 1.4% of cases. The location of the septa must be considered when planning for dental implants. In addition, septa in the upper and posterior regions of the maxillary sinus may interfere with mucociliary clearance.
