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.
Ranula in a female. A ranula usually presents as a translucent, blue, dome-shaped, fluctuant swelling in the tissues of the floor of the mouth. If the lesion is deeper, then there is a greater thickness of tissue separating from the oral cavity and the blue translucent appearance may not be a feature.
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 ...
Masseteric hypertrophy (enlargement of the masseter muscle's volume) can present as facial swelling in the parotid gland area and may be confused with 'true' parotid gland swelling. The specific cause of masseteric hypertrophy is still unclear, but it may be related to tooth grinding or malocclusion.
Historically, bilateral parotid and lacrimal gland enlargement was characterized by the term Mikulicz's disease if the enlargement appeared apart from other diseases. If it was secondary to another disease, such as tuberculosis, sarcoidosis, lymphoma, and Sjögren's syndrome, the term used was Mikulicz's syndrome.
Salivary gland dysfunction affects the flow, amount, or quality of saliva produced. A reduced salivation is termed hyposalivation.Hyposalivation often results in a dry mouth condition called xerostomia, and this can cause tooth decay due to the loss of the protective properties of saliva.
Parotid gland swellings can also be due to benign lymphoepithelial lesions [clarification needed] caused by Mikulicz disease and Sjögren syndrome. Swelling of the parotid gland may also indicate the eating disorder bulimia nervosa, creating the look of a heavy jaw line. With the inflammation of mumps or obstruction of the ducts, increased ...
However, the condition may arise anywhere minor salivary glands are located. [nb 1] It has also been occasionally reported to involve the major salivary glands. [2] [3] It may be present only on one side, or both sides. [1] The lesion typically is 1–4 cm in diameter. [4] Initially, the lesion is a tender, erythematous (red) swelling. Later ...
