Occipitalization of atlas with other associated anomalies of skull M. Sharma, B. Singh, A. Abhaya and H. Kumar SUMMARY Congenital fusion of the atlas with the occipital bone is the common denominator of a galaxy of skull defects. Some skull anomalies may result in sudden unexpected death. Seventy dry skulls were obtained from the Department of Anatomy. Of these, 2 skulls showed occipitalization. These were photographed and radiographed. Several measurements, including cranial index, dimensions of the foramen magnum, basal angle and basal impression, were taken. Both skulls showed near by complete fusion of the atlas with the occipital bone. A continuation of the confluence of the sinuses only to the left transverse sinus was observed in both skulls.
