Sialoadenosis

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

Etiology is different. These can be:
 * mainly affected by gl. parotid;
 * swelling is usually symmetrical, may be recurrent or persistent;
 * salivary secretion is reduced → risk of ascending infection from the oral cavity.
 * drug sialoadenosis (antihypertensives, β-sympathomimetics);
 * endocrine sialoadenosis (diabetes mellitus, pregnancy);
 * metabolic sialoadenosis (hypoproteinemia).

Diagnosis is based on:
 * 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 či ultrasound examinations show only an enlarged gland without structural changes.

Therapy consists of treating the triggering factor.
