Abstract : Objectives: The purpose of this study was to evaluate maxillary sinus volume in both genders in a Saudi sample and among different skeletal patterns. Methods: This retrospective cross-sectional study included 52 CBCT scans of 18 years or older individuals with full dentition and healthy medical history. Maxillary sinus in each side was first segmented; then, the volume was measured for each side independently using OnDemand3DTMDental. Finally, the mean value of both sides was calculated to produce mean maxillary sinus volume in mm3. Cephalometric tracings were conducted on cephalograms obtained from CBCT scans. Beta and AXB Angles were the measurements chosen to identify the sagittal skeletal pattern. Frankfort-mandibular plane angle (FMA) was selected to determine the vertical skeletal pattern of the study subjects. Other linear and angular measurements were performed to analyse the skeletal patterns in both sagittal and vertical planes. Descriptive statistics were conducted, data were analyzed, compared and correlated using paired t-test, One-Way ANOVA, Chi-squared test and correlation coefficient. The significance level was set at p< 0.05. Results: Fifty-two CBCT scans were included in this study (23 males and 29 females), with a mean age of 36 (±14) years. The mean maxillary sinus volume was 14887 (±5030.79) mm3. Males had statistically significant larger maxillary sinus volume (16517±5335 mm3) compared to females (13595 ±4,452 mm3) (P= 0.036). There was no statistically significant difference in maxillary sinus volume among all other cephalometric measurements (P> 0.05). Conclusion: Maxillary sinus volume in the studied Saudi sample was larger among males; thus, it could be used for gender identification. However, different skeletal patterns have no statistically significant differences in maxillary sinus volume.
