Prominentia canalis facialis
Definition
The prominence of the facial canal (prominentia canalis facialis; prominence of aqueduct of Fallopius) indicates the position of the bony canal in which the facial nerve is contained; this canal traverses the labyrinthic wall of the tympanic cavity above the fenestra vestibuli, and behind that opening curves nearly vertically downward along the mastoid wall.
