Evaluation of the Basal and Sphenobasion angles using CT Scan in the Iranian population

Abstract

Objectives: This study aimed to find the difference in the values of the cranial base angles among Iranian adults and investigate the relationship between the Basal and Sphenobasion angles. Methods: 100 individuals (50 males and 50 females) aged between 18 to 60 participated in this cross-sectional study which was carried out from September 2018 to September 2019 in the imaging centers affiliated with the Faculty of Medicine, Tehran University of Medical Sciences and Basal and Sphenobasion angles were measured in all of the participants. Results: A significant correlation was observed between age and Sphenobasion angle in the male group (P= 0.0001, r= 0.439), but no positive relation was observed between Sphenobasion angle and age in the female group (p=0.309). The results of this study exhibited the significant relations between the Basal and Sphenobasion angles in the females and males (P= 0.001, r= 0.396 and P= 0.0001, r= 0.534 respectively). Conclusion: This study showed positive correlations between the Basal angle and age in the females and males and significant relations between the Basal and Sphenobasion angles in the two genders.
