Sialoadenitis
Sialodenitis (also known as sialoadenitis) is a condition that occurs when one or more of your salivary glands become inflamed and swollen. Your salivary glands are located in your mouth and throat and produce saliva, which helps moisten your mouth, digest food, and prevent infections.
Sialodenitis can affect any of your salivary glands, but it most commonly affects the parotid gland (located in front of your ear) and the submandibular gland (located under your jaw). It can be acute (sudden and short-lived) or chronic (long-lasting and recurrent).
In this blog post, we will explain what causes sialodenitis, what symptoms it can cause, how it is diagnosed, and how it is treated.
What Causes Sialoadenitis?
Sialodenitis can have various causes, depending on the type and severity of the condition. Some of the common causes include:
Bacterial infection:
This is the most common cause of acute sialodenitis. It can occur if the salivary flow is reduced by dehydration, illness, medication, or obstruction by a stone (sialolith) or a tumor. The bacteria that cause sialodenitis are usually Staphylococcus aureus or Streptococcus viridans, which normally live in your mouth but can multiply and invade your salivary glands when the conditions are favorable.
Viral infection:
This is a common cause of chronic sialodenitis. It can occur if you have a viral infection that affects your salivary glands, such as mumps, HIV, or cytomegalovirus. Viral sialodenitis can also be associated with autoimmune diseases, such as Sjogren’s syndrome or rheumatoid arthritis, which cause inflammation and damage to your salivary glands.
Obstruction:
This is a common cause of both acute and chronic sialodenitis. It can occur if something blocks the ducts that carry saliva from your salivary glands to your mouth, such as a stone (sialolith), a tumor, a cyst, or a stricture (narrowing). Obstruction can cause saliva to back up and stagnate in your salivary glands, leading to inflammation and infection.

Trauma:
This is a rare cause of sialodenitis. It can occur if you injure your salivary glands by biting your cheek, having dental surgery, or receiving radiation therapy.
What are the Symptoms of Sialoadenitis?
The symptoms of sialodenitis depend on which salivary gland is affected, how severe the inflammation is, and whether there is an infection or not. Some of the common symptoms include:
Pain and swelling in the affected salivary gland. The pain may be worse when you eat or drink, especially sour foods or beverages that stimulate saliva production.
Redness and warmth over the affected salivary gland. The skin may also feel tight and tender to the touch.
Fever and chills if there is an infection. You may also feel generally unwell and have a headache, sore throat, or swollen lymph nodes.
Dry mouth (xerostomia) if there is reduced saliva production. This can cause difficulty swallowing, speaking, or tasting food. It can also increase your risk of dental decay and oral infections.
Pus or blood in your saliva if there is an infection or an ulcer in your salivary gland. You may also notice a foul taste or smell in your mouth.
How is Sialoadenitis Diagnosed?
Sialodenitis is diagnosed by examining your mouth and throat and asking about your symptoms and medical history. Your doctor may also perform some tests to confirm the diagnosis and identify the cause of sialodenitis. Some of the tests include:
Blood tests: These can check for signs of infection or inflammation, such as elevated white blood cell count, erythrocyte sedimentation rate (ESR), or C-reactive protein (CRP).
Culture and sensitivity: This involves taking a sample of pus or saliva from your affected salivary gland and sending it to a laboratory for testing. This can identify the type of bacteria causing the infection and the best antibiotic to treat it.
Imaging tests: These can show the size, shape, and location of your salivary glands and any stones, tumors, cysts, or strictures that may be causing an obstruction. Some of the imaging tests include ultrasound
Imaging tests: These can show the size, shape, and location of your salivary glands and any stones, tumors, cysts, or strictures that may be causing an obstruction. Some of the imaging tests include ultrasound, X-ray, CT scan, MRI scan, or sialography (injection of contrast dye into the salivary ducts).
Biopsy: This involves taking a small sample of tissue from your affected salivary gland and examining it under a microscope. This can help rule out cancer or other diseases that may affect your salivary glands.
How is Sialoadenitis Treated?
The treatment of Sialoadenitis depends on the cause, severity, and symptoms of the condition. The main goals of treatment are to relieve pain and swelling, clear the infection or obstruction, and restore normal salivary flow. The treatment may involve:
Medications: These include painkillers (such as ibuprofen or acetaminophen), antibiotics (if there is a bacterial infection), or corticosteroids (if there is severe inflammation or an autoimmune disease).
Hydration: This involves drinking plenty of fluids to prevent dehydration and increase salivary flow. You may also suck on sugar-free candies or chew sugar-free gum to stimulate saliva production.
Warm compresses: This involves applying a warm cloth or a heating pad over the affected salivary gland to reduce pain and swelling. You may also massage the gland gently to help drain any pus or saliva.
Sialagogues: These are substances that stimulate saliva production, such as lemon juice, apple cider vinegar, or citric acid. You may gargle or drink these substances to help flush out any bacteria or debris from your salivary glands.
Sialoendoscopy: This is a minimally invasive procedure that involves inserting a thin tube with a camera and a light (endoscope) into your salivary ducts. This allows your doctor to see inside your salivary glands and remove any stones, tumors, cysts, or strictures that may be causing an obstruction. This can also help irrigate and disinfect your salivary glands.
Surgery: This is a last resort option that involves removing part or all of your affected salivary gland. This may be necessary if there is a large stone, tumor, cyst, or stricture that cannot be removed by sialoendoscopy, or if there is a recurrent or severe infection that does not respond to antibiotics.
Conclusion
Sialoadenitis is a condition that occurs when one or more of your salivary glands become inflamed and swollen. It can have various causes, such as bacterial or viral infection, obstruction, trauma, or autoimmune disease. It can cause symptoms such as pain and swelling in the affected salivary gland, fever, and chills, dry mouth, pus or blood in your saliva, and difficulty swallowing or speaking.
It can be diagnosed by examining your mouth and throat and performing some tests, such as blood tests, culture and sensitivity, imaging tests, or biopsy. It can be treated by medications, hydration, warm compresses, sialagogues, sialoendoscopy, or surgery.

FAQs
Q: What are the salivary glands and what do they do?
A: The salivary glands are small organs located in your mouth and throat that produce saliva, which is a clear fluid that helps moisten your mouth, digest food, and prevent infections.
There are three pairs of major salivary glands: the parotid glands (located in front of your ears), the submandibular glands (located under your jaw), and the sublingual glands (located under your tongue). There are also hundreds of minor salivary glands scattered throughout your mouth and throat.
Q: How common is Sialoadenitis and who is at risk?
A: Sialodenitis is not very common, but it can affect anyone at any age. However, some people may be more prone to developing sialodenitis than others, such as those who have dehydration, malnutrition, immunosuppression, Sjogren’s syndrome, connective tissue diseases, xerostomic medications, sialolithiasis, chronic mechanical obstruction, trauma, dental surgery, or radiation therapy.
Q: How can I prevent Sialoadenitis?
A: You can prevent sialodenitis by maintaining good oral hygiene, drinking plenty of fluids, avoiding xerostomic medications or using saliva substitutes if needed, avoiding foods or drinks that may irritate your salivary glands or cause stones (such as dairy products, caffeine, alcohol, or spicy foods), and seeking medical attention if you have any signs or symptoms of sialodenitis.
Q: When should I see a doctor for Sialoadenitis?
A: You should see a doctor for sialodenitis if you have any of the following:
- Severe pain or swelling in your salivary gland that does not improve with home remedies
- Fever and chills that indicate an infection
- Difficulty breathing or swallowing that may indicate airway obstruction
- Pus or blood in your saliva that may indicate an ulcer or a rupture in your salivary gland
- Recurrent or persistent episodes of sialodenitis that may indicate an underlying condition or a complication
Q: How is Sialoadenitis treated and what are the possible complications?
A: The treatment of sialadenitis depends on the cause, severity, and symptoms of the condition. The main goals of treatment are to relieve pain and swelling, clear the infection or obstruction, and restore normal salivary flow. The treatment may involve medications, hydration, warm compresses, sialagogues, sialoendoscopy, or surgery. Some of the possible complications of sialodenitis include:
- Dehydration and electrolyte imbalance due to reduced saliva production
- Dental decay and oral infections due to dry mouth
- Abscess formation and sepsis due to untreated infection
- Fistula formation and scarring due to ulceration or rupture of the salivary gland
- Facial nerve damage due to inflammation or surgery of the parotid gland
