The jugular fossa is located in the temporal bone, posterior to the carotid canal and the cochlear aqueduct. In the bony ridge dividing the carotid canal from the jugular fossa is the small inferior tympanic canaliculus for the passage of the tympanic branch of the glossopharyngeal nerve .
Jugular foramen syndrome, or Vernet's syndrome, is characterized by paresis of the glossopharyngeal, vagal, and accessory (with or without the hypoglossal) nerves. [ 1 ] [ 2 ] Symptoms
A jugular foramen is one of the two (left and right) large foramina (openings) in the base of the skull, located behind the carotid canal. It is formed by the temporal bone and the occipital bone . It allows many structures to pass, including the inferior petrosal sinus , three cranial nerves , the sigmoid sinus , and meningeal arteries.
Basilar skull fractures are divided into anterior fossa, middle fossa and posterior fossa fractures. [1] Facial fractures often also occur. [1] Diagnosis is typically by CT scan. [1] Treatment is generally based on the extent and location of the injury to structures inside the head. [1]
However, coronal images require the person to hyperextend their neck, which must be avoided if any possibility of neck injury exists. [8] CT scans of the head increase the risk of brain cancer, especially for children. As of 2018, it appeared that there was a risk of one excess cancer per 3,000–10,000 head CT exams in children under the age ...
The foramina in the base of the skull are exit and entry points for veins, arteries and cranial nerves. The cranial nerves as they exit through various foramina.
Medulloblastoma is a common type of primary brain cancer in children. It originates in the part of the brain that is towards the back and the bottom, on the floor of the skull, in the cerebellum, or posterior fossa. [3] The brain is divided into two main parts, the larger cerebrum on top and the smaller cerebellum below towards the
The superior ganglion of the vagus nerve (jugular ganglion) is a sensory ganglion of the peripheral nervous system. It is located within the jugular foramen , where the vagus nerve exits the skull. It is smaller than and proximal to the inferior ganglion of the vagus nerve .
