3D evaluation of bony orbit characteristics in relation to age, sex, and symmetry: a quantitative CT study

BackgroundIdentifying accurate data about the bony orbit features according to age, sex, and symmetry is crucial for the effective treatment of orbital pathologies.PurposeTo analyze changes in the dimensions of the orbital aperture and volume of the bony orbit according to age and sex, and to evaluate individual symmetry using 3D computed tomography scans.Material and MethodsWe retrospectively analyzed the data obtained from 150 Turkish adults (75 men, 75 women) without an orbital pathology. The study sample was categorized into three age groups: 20-39, 40-59, and ≥60 years. We used the 3DSlicer and Syngo software to measure bony orbital volume (BOV) and the dimensions of the orbital aperture.ResultsThe BOV showed no difference between the left and right orbit for each individual, while orbital height and width were significantly different between the two sides (P < 0.05). The mean BOV for both orbits was significantly higher in the ≥60-year age group compared to the 20-39-year age group (P < 0.05). In all age categories, men exhibited a larger BOV than women (P < 0.001). There were no significant differences in BOV across age groups for either sex (P > 0.05). However, the direct effect of age on BOV was found to be significant only in women (p < 0.05)ConclusionOur findings indicate a significant relationship between aging and BOV, particularly in women, and individual asymmetry in orbital height and width parameters. These results provide accurate normative data for the diagnosis and treatment of orbital pathologies.
