This nerve may be involved by paraganglioma, in this location referred to as glomus jugulare or glomus tympanicum tumours. Tympanic nerve The tympanic nerve (nerve of Jacobson) is a branch of the glossopharyngeal nerve found near the ear. It arises from the petrous ganglion, and ascends to the tympanic cavity through a small canal, the inferior tympanic canaliculus, on the under surface of the petrous portion of the temporal bone on the ridge which separates the carotid canal from the jugular fossa. In the tympanic
