We aimed to evaluate whether the nasal septum deviation affects the development of sinonasal structures. Patients who had undergone paranasal sinus computed tomography (PNS-CT) imaging due to nasal obstruction were divided into 3 groups according to the septal deviation angle; group I: 0°to 9°, group II: 10°to 15°, and group III: > 15°. The features of sinonasal structures were recorded when evaluating PNS-CT. There were totally 234 patients, 119 patients in group I, 68 in group II, and 47 in group III. On the opposite side of the deviation, keros 3 was significantly more in group III (P < 0.001). Although the incidence of concha bullosa and agger nasi cell were not affected by the degree of deviation (P > 0.05), the incidence of Haller and Onodi cells were significantly higher in group III (P < 0.001). In addition, all cells were observed more in the opposite side of the deviation in each group (P < 0.001). Maxillary sinus retention cysts and hypoplasia of maxillary and frontal sinuses, as an indicator of the low pneumatization of the sinuses, are seen more on the same side of nasal septum deviation, increasing with the degree of deviation increases (P < 0.001). Nasal septum deviation affects the development of sinonasal structures by affecting the pneumatization. Preoperative PNS-CT evaluation is important in order to be aware of the situations that we may encounter during surgery and to provide adequate treatment.

Three-Dimensional Volumetric Analysis of Frontal Ethmoidal Cells and Evaluation of Influential Factors: A Helical Computed Tomography Study

In the present study, we aimed to assess frontal ethmoidal cells by using segmentation 3D software to establish a possible correlation between volume variation and both gender and age, as well as a relationship with Keros classification. Helical computed tomography images were obtained from 71 patients for analysis, in which the agger nasi cell, supra agger cell, supra agger frontal cell, supra bulla frontal cell, supraorbital ethmoidal cell, supra bulla cell, and frontal septal cell were identified and segmented to obtain their volume. Significant differences in volume were found for age and gender regarding agger nasi cells (p-value = 0.017), supra agger cells (p-value < 0.001), and frontal septal cells (p-value = 0.049). In the frontal septal cells, an increase of one year in age reduced the volume by 0.309, on average. According to Keros classification, the mean volumes were 10.07 and 25.64, respectively, for types II and III, both being greater than that of type I. Extracting volumetric data by using segmentation software in agger nasi cells, supra agger cells, and frontal septal cells may be useful for obtaining additional information related to age, in addition to possibly contributing to elucidating the anatomical variations in the region and an identification forensic tool.
