Abstract

Objectives: This study aims to determine the regional frequency of frontal cells classified by the International Frontal Sinus Anatomy Classification IFAC in local population radiologically. Patients and Methods: Between February 2018 and May 2019, a total of 300 frontal recess regions of 150 adults 88 males, 62 females; mean age 33.5±9.4 years; range, 18 to 54 years eligible for the inclusion criteria and undergoing paranasal sinus PNS computed tomography CT were included in the study. In CT analysis; agger nasi cells, supra agger cells, supra agger frontal cell, suprabullar cells, suprabullar frontal cells, supraorbital ethmoid cells and frontal septal cells were evaluated. Results: For anteriorly based cells, there were agger nasi cells, supra agger cells, and supra agger frontal cells with rates of 94.3% n=283 , 40.0% n=120 , and 14.7% n=44 , respectively. For posteriorly based cells, there were suprabullar cells, suprabullar frontal cells, and supraorbital ethmoid cells with rates of 59.7% n=179 , 7.3% n=22 and 7.3% n=22 , respectively. For medially based cells, there were frontal septal cells with a rate of 29.3% n=44 . Conclusion: Our study results suggest that the regional prevalence of frontal cells classified by the IFAC in Turkish population can be determined radiologically, providing contribution to the generation of estimates of the global prevalence of frontal cells.
