[Value of sonography and sialography in the diagnosis of salivary gland diseases].

134 patients with diseases of the salivary glands who underwent both real-time sonography and sialography were analyzed retrospectively. Using the two imaging methods a correct diagnosis was established in 92.5% of the patients. Masses of the salivary glands were detected in 98% (60/61) of the cases with the ultrasound examination, in 90% with sialography. The exact differentiation between a peripherally placed intrinsic lesion and an extrinsic mass that is intending the peripheral salivary gland contour often showed to be difficult as well with sialography and sonography. A chronic obstructive or non-obstructive sialadenitis could be correctly diagnosed in 91% of the cases with sialography, but only in 65% using sonography. The results demonstrate the complementary role of sonography and sialography in evaluating salivary gland disease.
