The tympanic nerve provides sensation to the middle ear (tympanic cavity). This includes the internal surface of the tympanic membrane. It also supplies the Eustachian tube, the parotid gland, and mastoid air cells. The tympanic nerve also gives parasympathetic supply to the otic ganglion. These neurons then provide secretomotor innervation of the parotid gland via the auriculotemporal nerve.
