dc.description.abstractBackground and Objective: The anatomy of the craniovertebral junction (CVJ) varies considerably across populations, yet comprehensive Turkish-specific morphometric data remain limited. We aim to establish normative CVJ measurements in Turkish males and females using computed tomography (CT). Study Design: Retrospective morphological study. Materials and Methods: A retrospective analysis of CT images from 500 patients (250 females and 250 males, aged 25-40 years) was conducted between January and December 2022. CVJ measurements were obtained, and sex-related differences were assessed. Results: The mean atlantodental interval was 1.45 +/- 0.01 mm, posterior atlantodental interval 19.35 +/- 0.09 mm, McGregor line 79.78 +/- 0.21 mm, Chamberlain line 76.95 +/- 1.21 mm, McRae line 36.27 +/- 0.12 mm, Wachenheim clivus-canal angle 154.65 +/- 0.45 degrees, sphenoid angle 121.15 +/- 0.39 degrees (no sex difference, p = 0.083), Welcher basal angle 130.02 +/- 0.28 degrees (higher in females, p < 0.001), basion-axial interval 7.13 +/- 0.07 mm (higher in males, p = 0.011), basion-dental interval 5.32 +/- 0.06 mm, and craniocervical tilt angle 123.94 +/- 0.44 degrees (higher in males, p < 0.001). Conclusion: This study provides a comprehensive CT-based analysis of CVJ measurements in Turkish adults, establishes normative morphometric values, and shows that most parameters exhibit sex-based differences. These population- and sex-specific reference data may be crucial for improving the accuracy of clinical assessments and surgical planning.
