[1][2] The neurons in the superior ganglion of the vagus nerve are pseudounipolar and provide sensory innervation (general somatic afferent) through either the auricular or meningeal branch.
[4][5] The superior ganglion contains neurons which innervate some of the dura mater lining the posterior cranial fossa via the meningeal branch of the vagus nerve.
[6][7] The neurons in the superior ganglion of the vagus nerve are embryonically derived from the neural crest.
[8] Pain in the external auditory canal (otalgia) can in rare cases be due to vagal neuralgia because of vascular compression of the vagus nerve (often by the posterior inferior cerebellar artery).
The affected neurons are found in the superior ganglion and innervate the ear via the auricular branch of the vagus.
