Being part and parcel of the ethmoid system and largely an outgrowth of those cells, its position, size and emptying mechanism are arranged to conform with the developmental vagaries of the ethmoid labyrinth. The nasal floor of the frontal sinus is mostly formed by the ethmoid bone, and therefore disease of the cells of
