“…The most commonly reported variations are precondylar tubercle 4 , third occipital condyle and prebasioccipital arch 5 , exostosis or tubercle on the anterior margin of foramen magnum 6 , fossa navicularis 7 and basioccipital cleft. 3 The detection and diagnosis of these craniovertebral anomalies are essential as many of them produce symptoms like transient quadriparesis and even death 8 or may lead to misinterpretations during diagnosis by radiological methods.Apart from their clinical significance they are of importance in anthropological and ethnological studies. In the present study we analyzed the prevalence of morphological variations in basiocciput regions of south Indian skull.…”

“…We could identify 3 reported cases of condylus occipitalis and 1 postmortem finding in the published literature. 2,4,12,18 In all of the live cases described, the clinical presentation was of cervical myelopathy, and in the majority of cases this was associated with atlantoaxial instability.…”

“…In the condylus occipitalis case described by Kotil and Kalayci, 4 an anterior surgical approach was proposed; however, 2 later authors achieved good outcomes by using posterior decompression with fixation. 2,12 In the only other operative description of occipitocondylar hyperplasia, posterior decompression without fusion was also performed, with a good outcome. The importance of preserving the atlantooccipital joints during surgery to avoid unnecessary fusion is therefore emphasized when faced with this rare condition.…”

“…This is occasionally located on the anterior margin of the foramen magnum. Some instances are expressed as a simple rounded tubercle, but in more developed cases an articular facet receives the tip of the odontoid process forming a true diarthrosis (Bergman et al 1996;Figueiredo et al 2008). The "condylus tertius" or "third occipital condyle" is an embryological remnant of the proatlas sclerotome.…”
