The tympanic canaliculus (also Jacobson's canaliculus, tympanic canal, inferior tympanic canaliculus, or temporal canaliculus) is a minute canal in the bony ridge that separates the carotid canal and jugular foramen.[1][2] The proximal opening of the canal is situated upon the inferior surface of the petrous part of the temporal bone; its distal opening is situated upon the floor of the tympanic cavity.[1] The canal gives passage to the tympanic nerve (tympanic branch of the glossopharyngeal nerve) (CN IX)) and inferior tympanic artery[3][2]
