- Abstract
Objective: To evaluate the morphometric and morphological features of zygomatic arch on cone beam computed tomography (CBCT) images and evaluate the usability of zygomatic arch instead of Frankfort horizontal plane. Methods: In this retrospective study, CBCT images of 130 adults (mean age: 38.43±16.20 years, 60 males, 70 females) were analyzed with Planmeca Romexis Viewer program. Approval was received from the Clinical Research Ethics Committee (2023/317). The length, angle, height of zygomatic arch, angle between line passing through superior border of zygomatic arch and Frankfort horizontal plane, distance between jugale and inferior border of zygomatic arch, jugale angle were measured. Typing was made according to the shape of zygomatic arch. Statistical analyses were performed with SPSS 22.0 package program. Results: A statistically significant difference was found between genders in length of zygomatic arch and jugale angle (p<0.001 and p=0.037, respectively). In zygomatic arch angle, the left side (134.53±6.69°) had statistically higher values than the right side (129.78±8.06°) (p<0.001). Zygomatic arch types were 29.6% flat, 40.4% curved and 30% wavy. There was no statistically significant difference in angle between line passing through superior border of zygomatic arch and Frankfort horizontal plane between the sides and between genders. Conclusion: Considering morphometric variables related to zygomatic arch length and jugale angle, the significant difference between genders may contribute to clinical or forensic medical evaluations. The line passing through superior border of zygomatic arch can be used as an alternative to Frankfort horizontal plane as a reference line in clinical applications and anthropological studies.
