The tympanic canaliculus[1] (also tympanic canal,[2] inferior tympanic canaliculus,[3] temporal canaliculus,[4] or Jacobson canal[2]) is a minute canal[2] in the bony wedge[2]/ridge[3] that separates the carotid canal[2][3] and jugular foramen[2]/jugular fossa.[3] 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.[2] The canal gives passage to the tympanic nerve i.e. tympanic branch of glossopharyngeal nerve (CN IX)),[2][3][4] and inferior tympanic artery.[4]
