[The significance of sialography in tumors of the parotid gland (author's transl)].
The significance of sialography in diagnosis of parotid gland tumors is based on the differentiation of chronic inflammatory, benign and malignant lesions. This method combined with history and physical findings will establish the diagnosis in 80% of cases with parotid gland tumors. Water-soluble contrast media are most useful for ductography. It provides good contrast, stays in the duct system for a sufficient period of time and will not cause inconvenience to the patient. Tomograms are particularly valuable in addition to the standard a.p. and lateral standard views. Chronic inflammation causes alterations with small paraductal contrast accumulations throughout the entire efferent duct system. Benign tumors may be recognized by straight ducts and interlobular paravasates. In malignant neoplasms filling defects are more characteristic than parenchymal staining. Peracute and subacute inflammations as well as tuberculosis are difficult to diagnose by sialography.
