Sialoadenosis

It is a painless, non-inflammatory hyperplasia and hypertrophy of the glandular parenchyma:

• gl. parotis is mainly affected;
• swelling is usually symmetrical, may be recurrent or persistent;
• salivary secretion is reduced → the risk of ascending infection from the oral cavity.

Etiology is different. These can be:

• drug sialoadenosis (antihypertensives, β-sympathomimetics);
• endocrine sialoadenosis (diabetes mellitus, pregnancy);
• metabolic sialoadenosis (hypoproteinemia).

Diagnosis is based on:

• a clinical picture with a positive endocrine or pharmacological history;
• sialographic finding – the gland is enlarged with rich branching of the outlets, the oppression of which later creates the so-called image of a dead tree (a bare tree);
• CT, MR or ultrasound examinations show only an enlarged gland without structural changes.

Therapy consists of treating the triggering factor.
