[Roentgen diagnosis of hypoglossal nerve canal (author's transl)].
Roentgenographic demonstration of the hypoglossal canal had been neglected for a long time, mainly because of superposition of other bone structures. For full evaluation of the hypoglossal canal, tomographic studies with multidirectional tube positions are essential. In order to visualize the canal in three dimensions and to examine its osseous contours in detail axial, frontal and oblique views should be obtained. The jugular tubercle -- forming the roof of the hypoglossal canal -- is of special significance. The roentgenologic features of infiltrating and expansive tumor growth in the region of hypoglossal canal are discussed.
