Salivary gland calculi account for the most common disease of the salivary glands, and may range from tiny particles to several centimetres in size. The majority of sialoliths occur in the submandibular gland or its duct and is a common cause of acute and chronic infections. While the majority of salivary stones are asymptomatic or cause minimal discomfort, larger stones may interfere with the flow of saliva and cause pain and swelling. This case report describes two patients presenting with submandibular gland sialolith and also provides a literature review regarding the salivary sialolithiasis.

HOW TO CITE THIS ARTICLE:
INTRODUCTIONSialoliths are calcified organic matter that forms within the secretory system of the major salivary glands. 1 These are calcareous deposits in the ducts of major or minor salivary glands or within the glands themselves. Sialolithiasis is a pathological condition caused by the obstruction of a salivary gland or its excretory duct by a calculus. It accounts for more than 50% of diseases of the major salivary glands and is thus frequently the cause of acute and chronic infections. Most common diseases of submandibular gland are seen in middleaged adults with male predilection. Males are affected twice as much as females. 2 It is often seen in submandibular gland (80-92%) followed by parotid gland (6-20%), sublingual and minor salivary glands (1-2%). 3 Intraductal stones occur more commonly than intraglandular stones. 4 The incidence being 12 in 1000 persons for the adult population. 5 The concentration of mucus is higher in the submandibular gland, accounting for the viscous nature of its secretions relative to the other salivary glands. This increased viscosity and subsequent relatively slower flow contributes to the propensity for submandibular salivary gland calculi.We are reporting two cases of submandibular gland sialolith and review of the literature regarding the salivary sialolithiasis.
