Introduction: The aim was to explore the developmental relationships between the angles of septal deviations and the degree of the mastoid pneumatization.   Materials and Methods: In total, 143 patients with a diagnosis of septal deviation who underwent septoplasty were included. The patients were divided into three groups in terms of the angles of the septal deviation. The angle of the septal deviations was defined as mild (<9 degrees), moderate (between 9 and 15 degrees) and severe (15 degrees and above). The degree of the mastoid pneumatization of each groups were compared.   Results: In right-sided septal deviation subjects, the right mastoid air cell volumes of group mild, moderate and severe were 6,31±2,33 cm3, 5,20± 1,51 cm3, and 5,31±1,57 cm3, respectively. The mean right mastoid volumes of each groups did not differ in right-sided deviations subjects (P> 0.05). The mean left mastoid volumes of each groups did not differ in right-sided deviations subjects (P> 0.05). In right-sided septal deviation subjects, the mean volume of the right and left-sided mastoid air cells of each groups did not differ (P> 0.05). In left-sided septal deviation subjects, the mean volume of the right and left-sided mastoid air cells of each groups did not differ (P> 0.05).   Conclusions: No developmental relationships between the angles of septal deviations and the degree of the mastoid pneumatization was observed in the study.
