Abstract

Objective.

To provide linear and volumetric measurements of zygomatic bone using cone beam computed tomography (CBCT) images.

Study Design.

CBCT images were assessed for 198 patients. Posterior and anterior zygomatic bone widths (M1 and M2), zygomatic bone projection (M3), zygomatic bone height (M4), combined zygomatic arch diameter (M5), maximum cortical thickness (M6), gray value obtained from maximum cortical thickness region (M7), minimum cortical thickness (M8), and gray value obtained from minimum cortical thickness region (M9) were measured. Volume and surface area measurements of the zygomatic bone were also conducted. Sex, age, and side were recorded for each patient. General linear model analysis of variance (ANOVA) was performed (P < .05).

Results.

Age (P < .001) and gender (P = .001) significantly affected M1. Gender significantly affected M3 (P = .003) and M4 (P = .000), with higher values for men. Gender (P = .000) and age (P = .000) significantly affected M5 variation. Only age had a significant effect on M6 variation, with an increase with age (P < .015). Only gender had a significant effect on M7 (P = .005), M8 (P = .000), and M9 (P = .004), with higher values for men. All the factors significantly affected zygomatic bone volume variation (gender, P = .000; age, P = .000; and side, P < .004).

Conclusion.

Detailed examination of the zygomatic bone region can be performed with CBCT images.
