Sialoadenitis

Sialoadenitis is the inflammation of one or more salivary glands, which can significantly impact a person's ability to produce saliva and maintain oral health. This condition can affect the major salivary glands (parotid, submandibular, and sublingual) or the numerous minor salivary glands throughout the mouth. Whether acute or chronic, bacterial or viral, sialoadenitis requires proper diagnosis and treatment to prevent complications and restore normal gland function. Understanding the various causes, symptoms, and treatment options is essential for effective management of this condition.

Overview

Sialoadenitis is the medical term for inflammation of the salivary glands, which are responsible for producing saliva to aid in digestion, maintain oral health, and protect against infections. The human mouth contains three pairs of major salivary glands—the parotid glands (located in front of the ears), submandibular glands (beneath the jaw), and sublingual glands (under the tongue)—as well as hundreds of minor salivary glands distributed throughout the oral cavity.

This condition can be classified as acute or chronic, with acute sialoadenitis typically developing rapidly over hours to days, while chronic sialoadenitis develops gradually over weeks to months. The inflammation can be caused by various factors including bacterial or viral infections, autoimmune diseases, medications, dehydration, or obstruction of the salivary ducts by stones or other blockages.

Sialoadenitis affects people of all ages but is more common in elderly individuals, those with compromised immune systems, and patients taking medications that reduce saliva production. The parotid glands are most commonly affected in viral sialoadenitis (such as mumps), while bacterial sialoadenitis more frequently affects the submandibular glands. Proper diagnosis and treatment are essential to prevent complications such as abscess formation, chronic gland dysfunction, or systemic spread of infection.

Symptoms

The symptoms of sialoadenitis can vary depending on the cause, severity, affected gland, and whether the condition is acute or chronic. Recognition of these symptoms is important for prompt diagnosis and treatment.

Primary Symptoms

  • Sore throat - Pain and discomfort in the throat, often accompanying gland inflammation
