Sialolithiasis

By Dr. Vishaal Bhat on Sunday 2 December 2007 with 0 comments



Sialolithiasis is a disease during which concrements (sialoliths) are formed inside the ducts or parenchyma of salivary glands thus slowing down or disabling flow of saliva. The disease affects the submandibular salivary gland (about 90% of cases) more often than the parotids or sublingual gland. Salivary stones originate from changed mucin of the saliva, by precipitation of salts around a core formed in the duct by a foreign object, cluster of epithelial cells and leukocytes, at the time of salivary glands inflammations. Stones may have rounded or spindled shapes. Clinical manifestations of sialolithiasis are repeated swelling of the gland area which appear especially before a meal when salivation increases and a stone prevents the saliva to pass freely inside the mouth. The saliva retention may result in an ascendant transfer of infection and occurrence of a secondary sialodenitis.

Upon long-term illnesses and repeated infections, the gland may become fibrously modified (sialodenitis fibroproductiva). Sialolithiasis therapy is surgical and lies at a salivary stone removal from the duct after discission of its wall. If a stone is positioned intra-parenchymatously at the submandibular salivary gland, an extirpation of the whole gland from the extra-oral side is indicated.
