Objective: The aim of this study was to carry out an epidemiological survey of the presence of Agger Nasi (AN) cells, using cone beam computed tomography (CBCT) images, in a Brazilian population in the region of Maringá - Paraná. Materials and Methods: The tomographic analyzes verified the thickness of the frontal beak (FB), anteroposterior length of the frontal isthmus, anteroposterior length of the FR and side-to-side, anteroposterior and vertical (cranio-caudal) diameter of the AN cells. Statistical analyzes were performed using the statistical program Jamovi (V2.5.5.0). For correlation analysis between the variables, the Spearman test was used. The study indicates the presence of AN cells in 100% of the individuals analyzed, being present bilaterally. Results: There was no significant correlation between FB and the AN cell. Significant positive correlations were found relating Right Agger Nasi Cell (ANC-R) and Left Agger Nasi Cell (ANC-L) with Front Recess (FR) and Frontal Sinus (FS). Conclusion: Anatomical knowledge on the part of professionals is of fundamental importance for a surgery to access the FS in a precise and uncomplicated way.
