“…Four parameters were measured for FM and eleven parameters for OC based on the detailed study of Naderi et al [3]. The parameters were anterior and posterior intercondylar distances FM shape was classified into seven types according to Chethan et al [13]: round, egg-shaped, tetragonal, oval, irregular, hexagonal and pentagonal ( Figure 6).…”

“…The occipital condyles (OC) of the skull are located with the superior articular facets of the atlas vertebra and form an important junction between the cranium and the vertebral column (Muthukumar et al, 2005;Naderi et al, 2005).…”

SUMMARY:The occipital condyle (OC) is an important area in craniovertebral surgery, but its anatomical features and the procedures concerning the OC have not been studied in detail yet. The aim of this study was to revisit the anatomy of the occipital condyle region and assess variations of the surrounding structures. Observations, on fifty dry skulls (dried specimens, 100 sides) and determined of condyle measurements. The mean length, width and height of occipital condyle were found to be 19.43±3.27 (right), 19.28±3.57 (left), 9.21±1.97 (right) 9.40±1.87 (left), 7.21±1.9 (right) and 7.33±2.74 mm (left), respectively. There were significant differences between right and left occipital condyles. The mean anterior intercondylar distance and posterior intercondylar distance were measured as 15.39±7 and 35.60±8.4 mm, respectively. Variations of occipital condyle shapes were kidney like (34.4%), S-like (25.6), triangular (13.3%) oval (10.0%), ring like (7.8%), eight like (6.7%) and deformed (2.2%) respectively. The condylar fossa presented in 60% of dry skull, 24% in right side and 36% in left side and also the condylar foramen was found in 60% of the specimens studied. There was no relation between the circumference of the head and the length of OC but we found relation between the circumference of the head and the width of OC (0.527) and foramen magnum circumference (0.433). The OC and FM are the main bony structures obstructing the surround of the brainstem. The differences in the size and the shape of occipital condyle have some differences and also similarities among racial subgroups. The posterior condylar vein may act asymmetrically. The correlation of the size of foramen magnum with the width of occipital condyles shows the importance of occipital condyle for lateral movements besides antero-posterior movements.

“…(Table 7) Different studies have quoted different facts and figures which have led to spectrum of findings. In a study conducted by Sait et al the commonest shape of right occipital condyles was found to be oval followed by S-shaped, triangular, eight-shaped, deformed, kidney-shaped, round and two-portioned while the commonest shape of left occipital condyles was oval followed by S-shaped, triangular, deformed, round, kidneyshaped, eight-shaped and two-portioned [7]. The commonest shape of occipital condyles was oval in both the studies but there was variation in the incidence of other shapes of occipital condyles in both the studies.…”
