What is 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:
- Parotid glands in front of the ear in the cheeks
- Submandibular glands under the chin
- Sublingual glands under the tongue
Sialadenitis mostly affects the parotid and submandibular glands.
It can be an acute (sudden), chronic (long term), or recurrent condition. It is a rare condition.
Who gets sialadenitis?
Sialadenitis is most common among elderly adults with salivary gland stones, calcified structures that can form inside a salivary gland and block the flow of saliva into the mouth. Sialadenitis can also occur in other age groups, including infants during the first few weeks of life.
Sialadenitis affects men and women of all races equally.
It often happens in people who are sick or recovering from surgery, or people who are dehydrated, malnourished, or immunosuppressed (when your body can’t fight disease).
What causes sialadenitis?
Sialadenitis is usually caused by a virus or bacteria. Poor oral hygiene can contribute to getting sialadenitis.
What are the symptoms of sialadenitis?
Symptoms of sialadenitis include:
- Enlargement, tenderness, and redness of one or more salivary glands
- Fever (when the inflammation leads to infection)
- Decreased saliva (a symptom of both acute and chronic sialadenitis)
- Pain while eating
- Dry mouth (xerostomia)
- Reddened skin
- Swelling in the cheek and neck region
If you notice any of these symptoms you should seek medical advice from your doctor. He or she may refer you to an otolaryngologist.
