ABSTRACT

Sialolithiasis is a common disease of the major salivary glands that accounts for between 11 and 70% of cases of obstructive gland disease. It involves the mechanical obstruction of the excretory salivary duct or glandular parenchyma by a calcareous formation known as a sialolith. It most frequently affects the submandibular gland (78%), followed by the parotid gland (20%) and the sublingual gland (2%). Reports suggest that it is more common in men (by a factor of 2:1), and particularly predominant in those between the fourth and sixth decades of life.
Clinical symptoms suggestive of sialolithiasis of the submandibular gland are easy to identity as the obstruction of the Wharton duct produces a swelling of the floor of the mouth and severe pain that varies during the day, increasing after meals in particular due to the overstimulation of the gland.
Occlusal X-rays of the lower arch are the simplest and cheapest form of diagnostic imaging. Other forms of imaging, such as ultrasonography, computed tomography, magnetic resonance imaging, sialography and endoscopy, show the exact location of the stone within the gland.
Treatment depends on the degree to which the functionality of the gland has been affected in terms of the chronicity of the inflammation and the size of the stone. Intraoral sialolithectomy using a CO2 laser is one treatment that offers good results in terms of preservation of the gland and a low morbidity rate. Moreover, in well chosen cases, this proves to be a minimally invasive technique with a low rate of complications.
