Abstract :Objectives: The aim of this study was to determine the incidence of agger nasi and frontal cells in a Turkish population and their relation to frontal sinusitis. Methods: A total of 412 non-contrast paranasal sinus computed tomography insert ignore into journalissuearticles values(CT); images taken between March 2017 and June 2018 were examined retrospectively. Frontal cells were classified into four types according to Kuhn’s classification. The relation of agger nasi and frontal cells to frontal sinusitis was evaluated. Results: Of the 412 patients, 202 were males insert ignore into journalissuearticles values(mean age 34.8±14.9); and 210 were females insert ignore into journalissuearticles values(mean age 35.1±13.9);. agger nasi cell was detected in 214 insert ignore into journalissuearticles values(51.9%);, and frontal cell in 198 patients insert ignore into journalissuearticles values(48%);. Frontal sinusitis was detected in 68 patients insert ignore into journalissuearticles values(16.5%);. According to Kuhn’s classification, Type 1 frontal cell was detected most frequently. A significant relationship was observed between the presence of agger nasi and frontal cells and frontal sinusitis insert ignore into journalissuearticles values(p<0.001);. When the right and left frontal sinusitis were evaluated separately, the relationship of frontal cell types of Kuhn’s classification with frontal sinusitis was found to be significant on the right side, but not on the left side. Conclusion: Agger nasi and frontal cells are common paranasal sinus variations that play a role in the development of frontal sinusitis. Although most of the paranasal sinus variationsare considered as predisposing in the development of sinusitis, there are obvious differences in studies. For this reason, a higher number of comprehensive studies are necessary to reveal the relation between the presence of agger nasi and frontal cells and sinusitis.
