In xerosialography a xeroradiographic technique is applied to the conventional sialography. Xerosialograms of normal and diseased salivary glands were compared with those of conventional sialograms. On account of the edge effect of xeroradiography, fine branchings of the salivary ducts and glandular structures are clearly delineated by the xerosialography. The technique is particularly advantageous when the conventional sialogram fails to demonstrate the ducts and the glands overlapping the bone. Differentiation between normal and abnormal tissues is clearer, and location of the neoplasma in the parotid gland is more easily recognizable. Further improvement is needed, however, in order to reduce radiation exposure.
