Sialolithiasis refers to the formation of calculi within a salivary gland. If a calculus forms in the duct that drains the saliva from a salivary gland into the mouth, then saliva will be trapped in the gland. This may cause painful swelling and inflammation of the gland. Inflammation of a salivary gland is termed sialadenitis. Inflammation ...
Saliva stagnates and forms a mucus plug behind the stricture during sleep when the salivary output of the parotid is reduced. Then, when salivary secretion is stimulated, the mucus plug becomes stuck in the stricture. [1] The backlog of saliva behind the blockage causes the swelling, and the increased pressure inside the gland causes the pain.
A sialolithiasis is a salivary stone that may cause blockage of the ducts, most commonly the submandibular ducts, causing pain and swelling of the gland. [33] Salivary gland dysfunction is either a reduced (hyposalivation), or an increased (hypersalivation) production of saliva.
A salivary diverticulum (plural diverticuli) is a small pouch or out-pocketing of the duct system of a major salivary gland. [16] Such diverticuli typically cause pooling of saliva and recurrent sialadenitis , [ 17 ] especially parotitis . [ 18 ]
The blockage may be from a salivary stone, a mucous plug, or, more rarely, by a tumor, usually benign. Salivary stones (also called sialolithiasis, or salivary duct calculus) are mainly made of calcium, but do not indicate any kind of calcium disorder. [7] Other causes can be duct stricture (narrowing of the duct), infection or injury.
This occurs because of a ruptured salivary gland duct usually caused by local trauma (damage) in the case of mucous extravasation phenomenon and an obstructed or ruptured salivary duct in the case of a mucus retention cyst. The mucocele has a bluish, translucent color, and is more commonly found in children and young adults.
Minor trauma to the floor of the mouth is thought to damage the delicate ducts that drain saliva from the sublingual gland into the oral cavity. [2] The lesion is a mucous extravasation cyst (mucocele) of the floor of mouth, although a ranula is often larger than other mucoceles (mainly because the overlying mucosa is thicker). [3]
Sialectasis (also termed sialectasia, or siadochiectasis) [1] is cystic dilation of the ducts of salivary glands. [2] It may be caused by salivary duct strictures or stones (sialolithiasis). [3] It can also rarely be congenital. [4]
