Sialadenitis is an infection of the salivary glands. It is usually caused by a virus or bacteria.[1][2] The parotid (in front of the ear) and submandibular (under the chin) glands are most commonly affected.[1] Sialadenitis may be associated with pain, tenderness, redness, and gradual, localized swelling of the affected area. There are both acute and chronic forms.[3] 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.[2]
