About this study

A retrospective study was conducted on 367 patients aged 13 years and above. Four investigators, each with 2 to 6 years of experience in the field of radiology, evaluated computed tomography scans of the paranasal sinuses and the head of these patients. The optic nerves were classified into four types based on DeLano's classification, and their respective prevalence rates were determined. Additionally, the prevalence of optic nerve dehiscence and pneumatization of the anterior clinoid process was assessed.
