Sinus Maxillaris Morphometric Measurements and Comparative Anatomy Between Genders

Objective: This study aimed to investigate the usability of the maxillary sinus as a criterion in gender determination by comparing the dimensions of the maxillary sinuses in adult males and females using cone-beam computed tomography (CBCT). Methods: Our study was designed to measure individuals’ bilateral maxillary sinus height, width, and depth with CBCT. A total of 100 patients, 50 women and 50 men between the ages of 18 and 70, were included in the study. The height (H), width (W), and depth (D) of the sinus were measured in the coronal and axial planes, and their statistical significance was evaluated. Results: In our results, the confidence interval was determined as 95% and P < .05, was considered significant. Right height (P < .001), right width (P = .045), and left height (P = .015) parameters were statistically higher in males than in females. In the discriminant analysis, the parameter that gave the best discrimination was the right height with 63%. Conclusion: In our study, it was observed that the sinus maxillaris dimensions were larger in male individuals than in female individuals, but it was concluded that it is not a definitive criterion on its own and can be used as a supporting one.
