The otic ganglion is one of four parasympathetic ganglia of the head and neck. It receives parasympathetic fibers from the glossopharyngeal nerve.
Gross anatomy
- small and disc shaped
- located in the infratemporal fossa
- it lies immediately below the foramen ovale, medial to the mandibular division of the trigeminal nerve
- supplies secretomotor fibers to the parotid gland.
Roots
- parasympathetic root
- from the inferior salivary nucleus via the glossopharyngeal nerve and branch off the tympanic nerve (Jacobson's nerve) to form the tympanic plexus in the middle ear and then exit as the lesser petrosal nerve. The lesser petrosal nerve then passes from the foramen ovale to the ganglion and then fibers reach the parotid gland as the auriculotemporal nerve.
- sympathetic root
- via the middle meningeal artery, vasomotor fibers from the superior cervical ganglion pass through the ganglion without synapsing and course though the auriculotemporal nerve and supply the parotid gland
- sensory root
- via the auriculotemporal nerve is sensory to the parotid gland.
