Dr Ronald Chin’s Overview of Acute Sialadenitis
What Is Acute Sialadenitis?
Acute sialadenitis is an inflammatory condition that affects the salivary glands, primarily caused by bacterial or viral infections. As an ENT specialist, I frequently encounter this condition, especially in patients with underlying health issues or risk factors such as dehydration or poor oral hygiene. Understanding the causes, symptoms, and treatment options can help you seek prompt medical care and avoid complications.
Acute sialadenitis refers to the sudden onset of inflammation in one or more of the salivary glands. While there are three pairs of major salivary glands—parotid, submandibular, and sublingual—this condition most commonly affects the parotid glands, located near the jaw and in front of the ears. The infection typically results from the obstruction of the salivary ducts, leading to a buildup of bacteria or viruses within the gland.
Causes and Risk Factors
The primary cause of acute sialadenitis is bacterial infection, with Staphylococcus aureus being the most frequent culprit. Other bacterial pathogens include *Streptococcus pneumoniae, S. viridans, and Haemophilus influenzae. Viral infections, such as mumps, HIV, influenza, or coxsackie virus, can also trigger inflammation.
Certain factors can increase your risk of developing this condition:
- Dehydration: Reduces saliva flow, promoting bacterial growth.
- Radiation Therapy: Can damage salivary glands and impair their function.
- Post-operative Recovery: Limited fluid intake can lead to gland stasis.
- Malnutrition: Weakens the immune system, making infections more likely.
Recognizing the Symptoms
The symptoms of acute sialadenitis can be uncomfortable and progressively worsen if untreated. Common signs include:
- Swelling and tenderness of the affected gland (often unilateral).
- Redness (erythema) and warmth over the swollen area.
- Pain that worsens during meals due to increased salivary production.
- Purulent drainage from the duct opening (often seen as pus discharge).
- Trismus or difficulty opening the mouth, particularly in severe cases.
Diagnosis and Treatment
A clinical diagnosis is typically made through a physical examination. Imaging techniques such as ultrasound or CT scans can help confirm the diagnosis and rule out abscess formation or obstructions like salivary stones.
Treatment focuses on resolving the infection, relieving pain, and promoting gland drainage:
- Antibiotics: Target bacterial infections and are the first line of treatment.
- Analgesics: Help manage pain and discomfort.
- Hydration: Encourages saliva flow and prevents further stasis.
- Warm Compresses & Gland Massage: Stimulate drainage and reduce swelling.
Potential Complications
If left untreated, acute sialadenitis can lead to the formation of a salivary gland abscess—a localized collection of pus requiring surgical drainage. Chronic infections or scarring of the salivary ducts may also occur in recurrent cases.
When to See an ENT Specialist
If you notice swelling, pain near your jaw, or discharge from your salivary ducts, it’s important to consult an ENT specialist promptly. Early treatment prevents complications and ensures proper gland function.
In conclusion, acute sialadenitis is a manageable condition when addressed early. With proper treatment and preventive measures—like staying hydrated and maintaining good oral hygiene—you can reduce your risk of future infections and ensure your salivary glands function optimally.
