The use of the roentgenogram in the study of the nasal accessory sinuses has become a necessity. Few will dispute this fact, although much discussion still prevails as to the method which offers the most efficient use of this aid to diagnosis. In order, if possible, to standardize the technic of roentgenology of the skull, various systems of topography have been worked out. Many of these have been too elaborate to be practical. A few positions have come into such general use that they may be regarded as standard. These produce uniformly good roentgenograms, but the diagnostic value of each is limited.
A general view the paranasal cavities and an indication of the depth of the sphenoidal sinus are included in roentgenograms taken in the lateral position; but because the cavities of one side are directly superimposed on those of the other, the size and extent of corresponding right
