I wish to present a method of roentgenographic study of the ethmoid labyrinths which permits examination of the individual cells without superimposed neighboring structures and also projects the sphenoid sinus of the same side into a position for examination. The sphenoid sinus is further studied in a lateral and in an axial view.
The positions usually employed for the examination of the ethmoid labyrinth do not permit a study of the individual cells. The Rhese position has furnished the nearest approach to a satisfactory picture, but the position of the projected Fig. 1.—In A and B, the line R represents the direction of the ray in the Rhese position. The tube is centered through the orbit from the upper margin of the opposite pinna. M indicates the direction of the ray in the modified position. The tube is centered 10 degrees above the line R. In C, R
