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. [2]
Common symptoms include fever, headache and bilateral or unilateral parotitis (swelling of the parotid gland on one or both sides of the face). The parotid gland is usually swollen and tender. Parotid swelling usually occurs 16–18 days after exposure to the virus.
Infections involving the salivary glands can be viral or bacterial (or rarely fungal). Mumps is the most common viral sialadenitis. It usually occurs in children and involves pain in front of the ear, swelling of the parotid, fever , chills, and headaches.
Unless the individual has an impaired immune system, e.g., owing to HIV or cancer-related immune suppression, [22] recurrent infections tend to be mild in nature and may be brought on by stress, sun, menstrual periods, trauma or physical stress. [23] Mumps of the salivary glands is a viral infection of the parotid glands.
A minor salivary gland biopsy, usually taken from the lip, [26] may be carried out if there is a suspicion of organic disease of the salivary glands. [1] Blood tests and urinalysis may be involved to exclude a number of possible causes. [1] To investigate xerophthalmia, the Schirmer test of lacrimal flow may be indicated. [1]
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.
These red dots represent the ducts of minor salivary glands which have become inflamed by heat. [6] [7] The condition is painless. [4] If a denture is normally worn while smoking, then the mucosa underneath the denture appears unaffected by the condition. [8] In severe cases, the mucosa may show fissuring and develop a "dried lake bed ...
Ludwig's angina (Latin: Angina ludovici) is a type of severe cellulitis involving the floor of the mouth [2] and is often caused by bacterial sources. [1] Early in the infection, the floor of the mouth raises due to swelling, leading to difficulty swallowing saliva.
