The tympanic plexus is a nerve plexus within the tympanic cavity formed upon the promontory of tympanic cavity by the tympanic nerve (branch of the inferior ganglion of glossopharyngeal nerve (CN IX)), and the superior and inferior caroticotympanic nerves (post-ganglionic sympathetic branches of the internal carotid plexus).[1]
The lesser petrosal nerve (which may be considered a continuation of the tympanic nerve) traverses the tympanic plexus.[1]
