“…[11] There are also differences in literature regarding the relationship between AN cell and frontal sinusitis. Eweiss et al, [10] Kubota et al, [12] and Del Gaudio et al [13] found no relation between AN cell and frontal sinusitis, wheras Yegin et al [14] reported the presence of sinusitis as significantly higher on the side of the AN cell. We also found a statistically significant relationship between frontal sinusitis and AN cell (p<0.001).…”

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 (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 (mean age 34.8±14.9) and 210 were females (mean age 35.1±13.9). agger nasi cell was detected in 214 (51.9%), and frontal cell in 198 patients (48%). Frontal sinusitis was detected in 68 patients (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 (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.

Introduction The maxillary sinus and its variations are very important to dentistry and rhinology. Objective To investigate the effect of the accessory maxillary ostium (AMO) on the variations of adjacent structures of the maxillary sinus. Methods The computed tomography (CT) images of 400 patients were retrospectively evaluated. The prevalence of AMO was calculated. The relationship between morphological variations of adjacent structures of maxillary sinus such as agger nasi cell (ANC), Haller cell (HC), nasal septum deviation (NSD), hypertrophy of inferior concha (HIC), pneumatization of middle concha (PMC), mucus retention cyst (MRC), mucosal thickening (MT), and maxillary sinusitis (MS), as well as the presence of AMO, were investigated. Results Presence of AMO was diagnosed in 42 patients (10.5%), having been found in 4.5% of the patients only on the right side, in 1.25% of the patients only on the left side, and in 4.75% of the patients on both sides. There is an increasing incidence of ANC, HC, NSD, HIC, and PMC in the presence of AMO and MS. There is a decreasing incidence of MRC in the presence of AMO. Furthermore, AMO does not affect the incidence of MT. Conclusion This study showed that most parameters, except for MRC and MT, had increasing incidence in the presence of AMO. It is important for radiologists and rhinologists to have knowledge about the location of AMO and the presence of variations of MS adjacent structures to avoid surgical complications.
