Objectives: Performing septorhinoplasty surgery requires comprehensive knowledge of nasal morphology. The effect of racial differences on nasal bone morphology has gathered increasing interest. However, previous studies have primarily focused on the Western population with a few studies assessing the Middle Eastern participants. We aimed to provide itemized measurements of the nasal bone morphology as the baseline data for the Middle Eastern population. Study Design: This was a retrospective cross-sectional single-center study. Materials and Methods: We included patients who underwent maxillofacial computed tomography between February and August 2019 at King Fahad Hospital of University. The Kolmogorov–Smirnov test was used to check the assumption of data normality. The Mann–Whitney U-test and Student's t-test were used for nonsymmetrical and symmetrical variables, respectively. One-way analysis of variance was used for symmetrical data. Chi-square test was used to compare the categorical variables. Results: We included 276 cases. The mean right and right nasal bone length was significantly larger in men than in women. Moreover, patients with severe nasal septal deviation angle had significantly lower left and right medial bone thickness, as well as the internasal angle. Conclusion: There were significant between-sex differences in the nasal bone morphology. There was no side predilection for deviated nasal septum and nasal bone thickness. However, severe cases of deviated nasal septum presented a lower medial nasal bone thickness, which could be attributed to ethnic variations in the Middle Eastern population.
