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]
About 85% of stones occur in the submandibular gland, [3] and 5–10% occur in the parotid gland. [2] In about 0–5% of cases, the sublingual gland or a minor salivary gland is affected. [2] When minor glands are rarely involved, caliculi are more likely in the minor glands of the buccal mucosa and the maxillary labial mucosa. [4]
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.
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. [2] Bacterial sialadenitis is usually caused by ascending organisms from the mouth.
The Heerfordt-Waldenstrom syndrome consists of sarcoidosis with parotid enlargement, fever, anterior uveitis, and facial nerve palsy. [2] IgG4-related sialadenitis: This term refers to IgG4-related disease (IgG4-RD) involving any of the major salivary glands, i.e. parotid or submandibular glands. This is often symmetrical and is usually ...
Pain is more common in patients with parotid cancer (10–29% feel pain) than those with benign neoplasms (only 2.5–4%), [23] but pain itself it not diagnostic of malignancy. Episodic swelling of major salivary glands accompanied by pain and related to salivary stimuli suggests duct obstruction.
Sialodochitis (also termed ductal sialadenitis), [1] is inflammation of the duct system of a salivary gland. [2] This is compared to sialadenitis, which is inflammation of the gland parenchyma. [3] Sialodochitis may be associated with salivary duct strictures and salivary stones. [4] It is common in both the parotid glands and submandibular ...
The salivary glands in many vertebrates including mammals are exocrine glands that produce saliva through a system of ducts. Humans have three paired major salivary glands (parotid, submandibular, and sublingual), as well as hundreds of minor salivary glands. [1] Salivary glands can be classified as serous, mucous, or seromucous (mixed).
