160 patients with chronic diseases of parotis were examined (age between 25 and 75 years).

Clinical data: All patients were divided into 3 groups: 1. Sialozis – 24 patients. 2. Sialoadenitis – 34 patients. 3. Lymphadenitis – 102 patients. Sialoisz: Glandule hyperechogenic in form interstitial grows is visible on a sonogram. Sialoadenitis: Cavity is one form of parenchyma destruction that describes siaoloadenitis. Lymphadenitis: Simple hypoechogenic formation with sharp contours is common for lymphadenitis. Doppler: Sialoadenitis result: The blood flow is increased 20 times higher than norm. The blood flow is decreased in sialosis and slightly increased in lymphadenitis. Sonogram results were atypical for 4 patients with sialoadenit, elastografy was administered to classify the diagnosis of parotids diseases. Elastogramme results show that rigid formation in parotid gland has coefficient of rigidity −5.7, this is specific only for malignant tumor.

Results: Study results show that examination of patients should begin with ultrasonograffy. This allows for correct diagnosis of the inflammatory disease and spots the malignant tumor.

Key words: ultrasonografy; sialoadenitis; sialozis; elastografy
