Parotitis is swelling in one or both parotid glands. These are 2 large salivary glands that are between each ear and jaw.
The problem can be:
- Acute—Gets better in a short period of time with or without treatment
- Chronic—Causes long-term swelling or periods when things are worse and then better

This illness is more common in older adults and newborns. Other things that may raise the risk are:
- Recent surgery
Certain health problems, such as:
- HIV infection
- Sjogren syndrome
Blocked saliva flow from:
- Salivary stone in the parotid gland
- Mucus plug in a salivary duct
- Mental health problems, such as depression or eating disorders
- Use of certain medicines
- Radiation therapy for head and neck cancer
The doctor will ask about your symptoms and health 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.
Pictures may be taken of the area. These may be done with:
- Sialography to view the ducts in and around the parotid gland
- CT scan
- MRI scan
