Sialolithiasis

 

a disease in man characterized by the formation of calculi within a salivary gland or excretory duct. Sialolithiasis is caused by the chronic inflammation of a gland. The submandibular gland is usually affected, with the causative agent being an inflammatory disease in the teeth of the lower jaw. The concentration of mineral salts in the saliva increases, and the passage of saliva through the ducts is decelerated. The mineral salts, which are usually calcium phosphate and calcium carbonate, are deposited on a cellular base of a duct or glandular body.

A salivary calculus weighs from several milligrams to several grams. If a calculus is small, the gland temporarily enlarges, causing a dull pain. A large calculus can completely close a ductal lumen, causing severe retention of saliva, acute pain in the submandibular region, and, often, a glandular abscess or phlegmon.

Sialolithiasis is sometimes treated with medications, including antiseptics and antispasmodics; surgical treatment is more common.

Sialendoscopy is a minimally invasive procedure for salivary gland diseases, and its main indications are sialolithiasis, non-stone obstructive salivary gland diseases, including chronic idiopathic recurrent sialadenitis, JRP, RAI-induced sialadenitis and auto-immune sialadenitis, such as Sjogren syndrome (3-7).

The terms sialoadenitis and sialolithiasis contain the Greek word for saliva-sialon ([phrase omitted]), instead of Latin term-saliva (which was used in the term glandulae salivariae).
There is also a theory in the literature stating that a retrograde infection might explain the sialolithiasis as food residues, substances, or bacteria which can migrate into the salivary ducts, becoming then a niche for more calcification [3-6].
Sialolithiasis accounts for more than 50% of major salivary gland diseases.
One hundred ninety-three patients were identified, of whom 108 (56%) had nonneoplastic disorders (sialolithiasis and sialadenitis).
Sialolithiasis means formation of calcific structures in salivary glands.

Sialadenitis and sialolithiasis cases were previously excluded from this study.

Contrast-enhanced computed tomography [Figure 1] demonstrated an irregular ring-enhancing loculated lesion with a homogenous low-density substance inside, without evidence of sialolithiasis. Diagnosis was compatible with parotid abscess with reactive neck lymphadenopathy.
