Infundibulum ethmoïdal - Infundibulum ethmoidale



The middle ethmoidal cells open into the central part of the middle meatus, and a sinuous passage, termed the infundibulum, extends upward and forward through the labyrinth and communicates with the anterior ethmoidal cells, and in about 50 per cent. of skulls is continued upward as the frontonasal duct into the frontal sinus.
