The jugular foramen is 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 [edit]

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 (aka cranial nerves number IX, X, and XI respectively).
The posterior transmits the sigmoid sinus (becoming the internal jugular vein) and some meningeal branches from the occipital and ascending pharyngeal arteries.

An alternative imaging based subclassification exists, delineated by the jugular spine which is a bony ridge partially separating the jugular foramen into two parts:

The smaller, anteromedial, "pars nervosa" compartment contains CN IX, Jacobson nerve (or the tympanic nerve, a branch of CN IX), and receives the venous return from inferior petrosal sinus.
The larger, posterolateral, "pars vascularis" compartment contains CN X, CN XI, Arnold's nerve (or the auricular branch of CN X involved in the Arnold's reflex, where external auditory meatus stimulation causes cough), jugular bulb, and posterior meningeal branch of ascending pharyngeal artery.

Clinical significance [edit]

Obstruction can result in "Vernet's syndrome".^[1]^[2]

Lesions involving the jugular foramen: clinical characteristics and surgical management.

CONCLUSION: Lesions involving the jugular foramen (JF) present as various diagnoses. Pulsatile tinnitus is more common in glomus jugulare (GJ) tumors, whereas otalgia and facial nerve paresis are more prevalent in temporal bone malignancies (TBMs).

Jugular paragangliomas are generally benign slow-growing tumors that can cause pulsatile tinnitus, hearing loss, and cranial nerves neuropathy. Progressive growth can also lead to intracranial extension. Historically, the treatment of choice for these lesions has been gross total resection. However,
