When fused the synchondrosis is often called the spheno occipital suture this is a misnomer as anatomically it is not a suture. Our purpose in reporting this case is to call attention to the serious complications which may follow the use of nasopharyngeal packing for control of epistaxis.

Basiocciput and basisphenoid. Basisphenoid bone in reptiles birds and many mammals a bone located at the base of the skull. Basisphenoid bone foramen fusion of basioccipital and basisphenoid bone union of the basioccipital and basisphenoid bones into one structure when this fusion does not normally occur such as in a species where these bones normally persist as separate entities impaired ossification of basisphenoid bone. 1 in this instance an abscess of the nasopharyngeal vault occurred and led to osteomyelitis of the basisphenoid and basiocciput meningitis and cranial nerve palsies.
Some groups advocate universal administration of. In humans the basisphenoid is present in the embryo but later. The tubercle was central in position.
Your input is welcome. This ontology is also used by the rat genome database. We wish to add the 4 cases studied at the montreal neurological institute and the montreal general hospital because they represent the two major subdivisions of chordoma of the basiocciput and basisphenoid viz that in which the tumor presents in the nasopharynx one fifth of the cases and that in which it is confined to the cranial cavity and its walls.
We believe this is the first such case reported in which recovery. One opening on the dorsal surface of the clivus with the blind end terminating posterior inferior to the sella turcica superior recess in basiocciput. Of the junction between basiocciput and basisphenoid and this region is intimately related to covering meninges and pons related blood vessels nerves.
Please contact us with any other questions about the mammalian phenotype ontology. Chordomas of skull base would be surgical. It is immediately in front of the bone that contains the opening through which the brainstem projects to connect with the spinal cord.
Long channel running through the basiocciput and posterior basisphenoid. The spheno occipital synchondrosis also known as the basiocciput synchondrosis is the synchondrosis between the basisphenoid and basiocciput bones which together when joined form the clivus. Short blind ending opening on the dorsal surface.
