| | |  | | © Reed Group | | | Salivary gland stones or sialolithiasis is a condition in which a stone (calculus) develops in the salivary gland. The stones are composed of concentrated salivary salts that have been precipitated by decreased salivary flow (salivary stasis). The presence of stones in the salivary gland can be very painful and cause swelling especially when eating. Chronic infection of the salivary glands (sialadenitis) can lead to decreased salivary flow and consequent stone formation. Pain caused by active infection in the glands, however, tends to be constant rather than worse when eating.
Chronic infection in the salivary glands is the predominant risk factor for stone formation although the exact cause of decreased salivary flow in the majority of cases is unknown (idiopathic). Individuals who have gout are at greater risk for salivary stone formation even without decreased salivary flow.
Incidence and Prevalence: Stones occur most commonly in middle-aged males. |
