Sialadenitis sialoadenitis is inflammation of salivary glands , usually the major ones, the most common being the parotid gland , followed by submandibular and sublingual glands. Sialadenitis can be further classed as acute or chronic. Acute sialadenitis is an acute inflammation of a salivary gland which may present itself as a red, painful swelling that is tender to touch. Chronic sialadenitis is typically less painful but presents as recurrent swellings, usually after meals, without redness. Causes of sialadenitis are varied, including bacterial most commonly Staphylococcus aureus , viral and autoimmune conditions.

Symptoms Symptoms. Signs and symptoms of sialadenitis may include fever, chills, and unilateral pain and swelling in the affected area. The affected gland may be firm and tender, with redness of the overlying skin.

Pus may drain through the gland into the mouth. Do you have updated information on this disease? We want to hear from you. Cause Cause. Sialadenitis usually occurs after decreased flow of saliva hyposecretion or duct obstruction, but may develop without an obvious cause. Saliva flow can be reduced in people who are sick or recovering from surgery, or people who are dehydrated, malnourished, or immunosuppressed.

A stone or a kink in the salivary duct can also diminish saliva flow, as can certain medications such as antihistamines , diuretics , psychiatric medications, beta-blockers , or barbiturates. It often occurs in chronically ill people with dry mouth xerostomia , people with Sjogren syndrome , and in those who have had radiation therapy to the oral cavity.

Other bacteria which can cause the infections include include streptococci, coliforms, and various anaerobic bacteria. Although less common than bacteria, several viruses have also been implicated in sialadenitis. Treatment Treatment. The treatment of sialadenitis depends on what type of microbe is causing the infection.

If the infection is bacterial, an antibiotic effective against whichever bacteria is present will be the treatment of choice.

If the infection is due to a virus , such as herpes, treatment is usually symptomatic but may include antiviral medications. Warm compresses, and gland massage may also be helpful if the flow is obstructed in some way. Good oral hygiene are also important. Occasionally an abscess may form which needs to be drained especially if it proves resistant to antibiotics or antiviral medication [1] [2] [3] [4] In rare cases of chronic or relapsing sialadenitis, surgery may be needed to remove part or all of the gland.

This is more common when there is an underlying condition which is causing the hyposecretion. Prognosis Prognosis. The prognosis of acute sialadenitis is very good. Most salivary gland infections go away on their own or are easily cured with treatment with conservative medical management medication, increasing fluid intake and warm compresses or gland massage. Acute symptoms usually resolve within 1 week; however, edema in the area may last several weeks.

Complications are not common, but may occur and can include abscess of the salivary gland or localized spreading of bacterial infection such as cellulitis or Ludwig's angina. Research Research.

Acute Submandibular Sialadenitis

Sialadenitis is an inflammation of a salivary gland. Salivary glands are the glands that make saliva, which helps with swallowing and digestion and protects your teeth from bacteria. There are three main salivary glands:. It can be an acute sudden , chronic long term , or recurrent condition.


Sialadenitis (Swollen Salivary Gland)

Coronavirus News Center. Case A year-old woman presented to the ED with pain and swelling on the right side of her neck. She stated the pain started earlier that morning and worsened when she ate or swallowed. The patient denied a recent or remote history of drooling, voice changes, or neck swelling. She reported no fevers, chills, or any other complaints, and had no pertinent medical history—specifically, no history of recent dental work. Her surgical history included tonsillectomy and cholecystectomy.
