Sialographic and ultrasonographic analyses of major salivary glands.

Seventy patients with major salivary gland diseases (60 parotis, 10 submandibular) were examined both with sialography and ultrasonography. The clinical and histopathological results were compared with radiological interpretations. Sialography was found to be 60% accurate for the diagnosis of salivary gland tumors and cysts and 63% for the diagnosis of inflammatory diseases. Ultrasonography diagnosed 95% of the tumors and 63% of inflammatory diseases accurately.
