Examinations of Sialopathies

By Dr. Vishaal Bhat on Sunday 2 December 2007 with 0 comments



A diagnosis of sialopathies is based on a meaningful combination of data obtained from a patient’s anamnesis and clinical examinations of a salivary gland by palpation and aspection. X-ray examination of the salivary glands area helps in diagnostics of sialolithiasis (a simple X-ray picture, e.g. at occlusal projection onto the mouth base).

Examination by sialography that uses injection of an X-ray contrast substance (Lipiodol Ultrafluid) into salivary gland ducts, shows not only changes at the ducts (obstructions of filling), but also parenchymatous modifications (e.g. in cases of chronic inflammatory states or tumors). It also informs about the functional ability of a salivary gland to extrude a contrast filling under 60 minutes.

For diagnostics of salivary glands tumors it is possible to utilize a resolution power of the computer tomography (CT), radiometric examination (scintigraphy by technetium Tc 99m), ultrasonography, thermography (contact crystal or infrared thermography).

In cases of suspect tumorous lesions, a puncture biopsy or per-operational histological examination of cryosections is performed. Sialometry (the Škach’s method) provides objective data on salivary secretion and helps to distinguish hypo-, normo- and hyper-salivation. The lower limit of a normal, physiological secretion of saliva is 10 ml in 30 minutes.
