Highlights & Basics
- Sialadenitis is the inflammation and enlargement of one or several major salivary glands. It most commonly affects parotid and submandibular glands.
- Bacterial infection can occur if salivary flow is diminished by illness or medication, or is obstructed by a sialolith (salivary stone). Most commonly caused by Staphylococcus aureus.
- Intermittent painless unilateral or bilateral swellings without accompanying signs of infection may be idiopathic or due to an underlying condition, such as ductal stenosis or autoimmune disease.
- Chronic sclerosing sialadenitis presents as a painless unilateral swelling that can mimic tumors. Biopsy is required for diagnosis.
- Airway compromise is an important potential consequence of acute glandular swelling.
