Comprehensive x-ray, ultrasonic and radionuclide examinations of 131 patients with chronic sialadenitis (n = 50), sialosis (n = 59), sialolithiasis (n = 9), autoimmune disorders (n = 6), and bulky processes (n = 7) of the parotid salivary glands were carried out. The diagnostic potentialities of each method in every of these conditions were analyzed. No correlation between the structural and functional disorders of the parotid glands could be traced. A complex of radiologic methods is necessary to fully assess the anatomic and functional status of the parotid glands. An algorithm of examination in such conditions is presented.
