The fundamental requirements for stereoscopic roentgenograms of the sphenoid sinuses do not differ from those for stereoscopic roentgenograms of other parts of the body, although the positions for the patient, the necessary apparatus and the anatomic structures differ considerably. In roentgenography of the sphenoid sinuses various positions for the head have been recommended; for instance, in the Granger position, shown in figure 1, the head is at an angle of 107 degrees. In another method the film is placed at an angle of about 24 degrees from the top of the table and a projection is made through the region of the vertex and the mouth, while in another method the head is placed on the side, parallel to the top of the table, and a lateral projection is made.
It is not my intention to offer diagnostic advantages gained from the use of any particular position, but rather to
