Parotitis(Sialadenitis; Salivary Gland Infection)

Pronounced: PEAR-uh-TIE-tiss

Definition

Parotitis causes inflammation in one or both of the parotid glands. These are two large salivary glands that are inside each cheek over the jaw in front of each ear.

Parotitis can be:

  • Acute—inflammation that resolves with treatment
  • Chronic—includes persistent inflammation or alternating periods of flare-ups and remission

Causes

An inflamed parotid gland has several causes. These vary depending on whether the condition is acute or chronic. The most common causes include:

  • Bacterial infection
  • Viral infection
  • Blockage of saliva flow
Risk Factors

Factors that may increase your chance of parotitis include:

Symptoms

Parotitis may cause:

  • Swelling in front of your ears, below your jaw, or on the floor of your mouth
  • Dry mouth
  • Strange or foul taste in your mouth
  • Pus draining into the mouth
  • Mouth or facial pain, especially when you are eating or opening your mouth
  • Fever, chills, and other signs of infection

If parotitis recurs, it can cause severe swelling into the neck and can destroy the salivary glands.

Diagnosis

Your doctor will ask about your symptoms and medical history. A physical exam will be done. This may be enough to make a diagnosis. Tests may include a blood test and a fluid sample from the parotid gland.

Imaging tests evaluate the parotid gland and surrounding structures. These may include:

Treatment

Parotitis may be resolved by treating the underlying cause. Medications that cause parotitis can be changed or stopped.

Other treatment options include:

Good Oral Hygiene

Flossing and thorough tooth brushing at least twice per day may help with healing. Warm salt-water rinses can help keep the mouth moist. If you smoke, talk to your doctor about ways you can quit.

Medications

Medications may include:

  • Antibiotics for bacterial infections (antibiotics are not effective for viral infections)
  • Anti-inflammatory drugs to manage inflammation and pain
Blockage Removal

Your doctor may need to remove a stone, tumor, or other blockage. Increasing saliva flow may be all that is needed to remove a mucus plug.

Prevention

To help reduce your chances of parotitis:

  • Get prompt treatment for any infections.
  • See your dentist for proper oral care as recommended.
  • Drink plenty of fluids throughout the day to avoid dehydration.
  • Receive the measles, mumps, and rubella (MMR) vaccination if you have not yet been vaccinated
