[Value and indications for high-resolution real-time sonography in nontumor salivary gland diseases].

308 patients with salivary gland diseases were investigated using real-time sonography. In 142 patients we suspected neoplasms of the salivary glands on the sonograms. In the remaining 166 patients we investigated the following entities: sialolithiasis (74 patients), acute sialadenitis (54 patients), abscess formation (16 patients), chronic sialadenitis or autoimmune disease (53 patients) and cysts of salivary gland (5 patients). The changes in the sonographic morphology of the different diseases will be described. The role of ultrasound in the diagnosis of the different diseases will be discussed and the indications for sonographic investigations are summarised.
