Question: What is (are) Sialadenitis ?
Answer: Sialadenitis is an infection of the salivary glands. It is usually caused by a virus or bacteria. The parotid (in front of the ear) and submandibular (under the chin) glands are most commonly affected. Sialadenitis may be associated with pain, tenderness, redness, and gradual, localized swelling of the affected area. There are both acute and chronic forms. Although it is quite common among elderly adults with salivary gland stones, sialadenitis can also occur in other age groups, including infants during the first few weeks of life. Without proper treatment, sialadenitis can develop into a severe infection, especially in people who are debilitated or elderly.

Question: What are the treatments for Sialadenitis ?
Answer: How might sialadenitis be treated? The initial treatment for sialadenitis is antibiotics active against S. aureus. Hydration, ingesting things that trigger saliva flow (such as lemon juice or hard candy), warm compresses, gland massage, and good oral hygiene are also important. Abscesses need to be drained. Occasionally, in cases of chronic or relapsing sialadenitis, a superficial parotidectomy or submandibular gland excision is needed.
