ptyalolithiasis
The formation or presence of a salivary calculus (concretion formed in any part of the body).
ptyalolithotomy
Incision of a salivary gland or duct for the removal of a calculus.
pulmolith
pyrolithic
Pertaining to, or designating, an acid now called cyanuric acid.
rhabdolith
A minute coccolith having a shield surmounted by a long stem and found at all depths in the ocean, from the surface to the bottom.
Coccoliths are composed of calcium carbonate as the mineral calcite and are the main constituents of chalk deposits; such as, the white cliffs of Dover.
rhinodacryolith
A lacrimal concretion in the nasal duct.
rhinolith
1. A calcareous concretion in the nasal cavity often around an undetected foreign body.
2. A nasal stone or concretion.
2. A nasal stone or concretion.
rhinolithiasis
The presence of a nasal calculus.
rhinopharyngolith
A concretion in the rhinopharynx.
A concretion or calculus in a sebaceous duct or gland: Professor Thompson explained to his students that a sebolith could also be found in a sebaceous follicle.
sialodocholithiasis
A disease causing and caused by calculi in the ducts of the major salivary glands.
sialolith
A calcareous concretion or calculus in the salivary ducts or glands, involving most commonly the submaxillary gland and its duct, less frequently the parotid and sublingual glands and their ducts, and seldom the minor salivary glands. Also called: salivary calculus and salivary stone.
sialolithiasis
1. The formation or presence of a salivary calculus; ptyalolithiasis.
2. The disease characterized by the formation of salivary calculi.
2. The disease characterized by the formation of salivary calculi.
Symptoms depend on the site of the calculus or calculi and whether infections, sometimes recurrent, are concerned. In the submandibular salivary gland, the site of 90 percent of such cases, large calculi are likely to obstruct the duct and result in swelling of the gland while eating. Also, ptyalolithotomy.
sialolithotomy
Incision of a salivary gland or duct for the removal of a calculus.
The majority of such incisions are made from within the mouth to remove a calculus from the submandibular salivary duct. Also, ptyalolithotomy.
splanchnolith
A calculus (hard lump) in the gastrointestinal tract.
