Popis: Objectives: This study was carried out to make morphometric and radiological analyses of the occipital foramen (OF), posterior condylar canal (PCC), posterior condylar vein (PCV), and occipital emissary vein (OEV). Methods: Morphometric analyses were performed on 91 adult human occipital bones and radiological analyses on computed tomography (CT) angiography images of 221 patients. PCC length and mean diameters of the internal and external orifices of PCC were measured and the number of OF on both sides was recorded for bony specimens. Prevalence of PCV and PCV size were investigated using CT angiography. Results: PCCs were observed in 60 bones (66%) on the left and 60 bones (66%) on the right side. Mean PCC length was 10.85 ±3.41 and 9.77±3.55 on the left and right sides, consequently. Mean internal orifice diameter was 3.87±1.99 mm on the left and 3.31±4.43 mm on the right side; mean external orifice diameter was 4.02±1.59 mm on the left and 3.89±1.52 mm on the right side. The majority of PCCs (75%-81.6%) had 2-5 mm diameter; only 5-13.3% were small in size (
