Otorhinolaryngology. Sialadenitis (sialoadenitis) is inflammation of salivary glands, usually the major ones, the most common being the parotid gland, followed by submandibular and sublingual glands. [1] It should not be confused with sialadenosis (sialosis) which is a non-inflammatory enlargement of the major salivary glands.
Blockage of the submandibular gland by a salivary stone with subsequent infection. Arrow marks pus coming out of the opening of the submandibular gland. Salivary gland diseases (SGDs) are multiple and varied in cause. [1] There are three paired major salivary glands in humans: the parotid glands, the submandibular glands, and the sublingual glands.
Parotid swelling can be an uncommon symptom of extrapulmonary tuberculosis (TB outside of the lungs). The usual symptoms are a cough, fever, weight loss, shortness of breath, chest pain, tiredness and chills. This is caused by the bacteria Mycobacterium tuberculosis. TB can also affect the heart, thyroid and adrenal glands but the main site of ...
The parotid gland is a major salivary gland in many animals. In humans, the two parotid glands are present on either side of the mouth and in front of both ears. They are the largest of the salivary glands. Each parotid is wrapped around the mandibular ramus, and secretes serous saliva through the parotid duct into the mouth, to facilitate ...
A sialolithiasis (a salivary calculus or stone) may cause blockage of the ducts, most commonly the submandibular ducts, causing pain and swelling of the gland. [33] Salivary gland dysfunction refers to either xerostomia (the symptom of dry mouth) or salivary gland hypofunction (reduced production of saliva); it is associated with significant ...
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.
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 ...
Chronic sclerosing sialadenitis is a chronic (long-lasting) inflammatory condition affecting the salivary gland. Relatively rare in occurrence, this condition is benign, but presents as hard, indurated and enlarged masses that are clinically indistinguishable from salivary gland neoplasms or tumors. It is now regarded as a manifestation of IgG4 ...
