		17:	Pneumolabyrinth: a new radiologic sign for fracture of the stapes footplate.
			著者: M F Mafee, G E Valvassori, A Kumar, D A Yannias, R E Marcus 雑誌名: Am J Otol. 1984 Jul;5(5):374-5. Abstract/Text A case of fracture of the footplate of the stapes resulting in air in the labyrinth is reported. The pneumolabyrinth was demonstrated by CT scan of the temporal bone but not by complex motion tomography. We consider pneumolabyrinth to be a new diagnostic CT finding in stapes footplate fracture.
