The nerve was not a direct upwards continuation of the cervical sympathetic trunk and ran caudodorsally very closely alongside with the extra-cranial segment of the internal carotid artery over medial surface of the tympanic bulla to enter the cranial cavity through the petrooccipital fissure (Fig.
These are: (1) the Kerckring ossicle (ko), (2) posterior intraoccipital synchondrosis (pio), (3) anterior intraoccipital synchondrosis (aio), (4) sphenooccipital synchondrosis (sos), (5) petrooccipital fissure (pof) and (6) occipitomastoid suture (oms).
The petrooccipital suture began to fuse by the age of 7.5 years in 104 cases (52%).
The lower clivus involves the jugular tubercule to the foramen magnum and occipital condyle.[2,3,7] The lateral margins of the clivus are the petrooccipital fissures through which the inferior petrosal sinus empties into the jugular bulb.[2,3,7] The clivus varies from 37 to 52 mm in length and averages 11 mm in width from the anterior narrow portion to 14.3 mm in width at the posterior widest portion.[8] To further simplify this anatomical description, the clivus is the bony floor of the midline of the posterior fossa in which the brainstem sits.
