The jugular foramen, a large aperture in the base of the skull. It is located behind the carotid canal and is formed in front by the petrous portion of the temporal, and behind by the occipital; it is generally larger on the right than on the left side

Contents

The jugular foramen may be subdivided into three compartments, each with their own contents.

* The "anterior" compartment transmits the inferior petrosal sinus.
* The "intermediate" transmits the glossopharyngeal, vagus, and accessory nerves.
* The "posterior" transmits the sigmoid sinus (becoming the internal jugular vein) and some meningeal branches from the occipital and ascending pharyngeal arteries.

Clinical significance

Obstruction can result in "Vernet's syndrome".cite web |url=http://www.bcm.edu/oto/grand/62394.html |title=Parapharyngeal Masses: Their Diagnosis and Management |format= |work= |accessdate=] cite journal |author=Erol FS, Kaplan M, Kavakli A, Ozveren MF |title=Jugular foramen syndrome caused by choleastatoma |journal=Clin Neurol Neurosurg |volume=107 |issue=4 |pages=342–6 |year=2005 |month=June |pmid=15885397 |doi=10.1016/j.clineuro.2004.08.006 |url=http://linkinghub.elsevier.com/retrieve/pii/S0303-8467(04)00124-6]
