Parotitis – Symptoms, Radiology, Treatment Antibiotics, vs Mumphs, ICD-10

Key Facts

  • Parotitis is an inflammatory condition that affects the parotid glands, which are the major salivary glands located in front and beneath each ear
  • It can be caused by various factors, including bacterial and viral infections, obstruction, dehydration, and autoimmune diseases
  • Patients might experience pain, swelling, and tenderness in the gland area, fever, and dry mouth
  • Treatment is highly dependent on the underlying cause and can range from antibiotics for bacterial infections to supportive measures like hydration and sialogogues (substances that stimulate saliva flow)

What is Parotitis?

Parotitis is an inflammation of the parotid glands. These glands are primarily responsible for producing saliva, playing a vital role in the digestion process and maintaining oral health. When these glands become inflamed, they can cause significant discomfort and potential complications, interfering with the normal function of producing and secreting saliva. Dealing with parotitis may present various symptoms and challenges, but with prompt treatment, most individuals recover fully without complications.

Who Does Parotitis Affect?

Understanding who is affected by parotitis can provide valuable insight into its risk factors, which include age, overall health status, lifestyle choices, and the use of specific medications. Recognizing these risks is crucial for prevention and early diagnosis, leading to more effective and efficient treatment options.

Various Age Groups

  • Children: Viral parotitis, including mumps, is more commonly observed in children. With vaccination programs, the incidence of mumps has significantly decreased in many regions.
  • Elderly Population: The elderly are more susceptible due to their weakened immune system, reduced hydration, and higher prevalence of medications that affect saliva production.

People with Specific Health Conditions

  • Individuals with chronic illnesses or autoimmune disorders are at a higher risk.
  • Patients who are dehydrated or have experienced rapid weight loss may also be susceptible, as saliva flow might be reduced.


  • Individuals who take certain medications that reduce saliva production might be at risk.
  • People with poor oral hygiene or a history of smoking and alcohol consumption can also be prone to the condition due to increased vulnerability to infections.

Symptoms of a Swollen Parotid Gland

Swelling in the parotid gland can lead to various symptoms, including:

  • Pain and Discomfort: Pain near the jaw or in the mouth, often exacerbated when eating. The pain might radiate towards the ears.
  • Swelling: Visible or palpable enlargement in the cheek area, in front or below the ear.
  • Dry Mouth (Xerostomia): Difficulty in swallowing and speaking due to reduced saliva production.
  • Altered Taste: Change in the sense of taste or having a constant metallic or bitter taste.
  • Fever and Chills: Accompanied by general malaise and fatigue.
  • Pus or Discharge: Presence of foul-smelling pus or discharge from the duct opening into the mouth.
  • Difficulty Opening the Mouth: Restricted movement due to pain and swelling.
  • Difficulty Eating: Pain and swelling can make chewing and swallowing uncomfortable.

Causes of Swollen Parotid Gland

A swollen parotid gland can occur due to various reasons:

  • Infections: Viral Infections such as mumps or influenza, Bacterial Infections typically caused by Staphylococcus aureus or other oral bacteria, often due to obstruction or reduced saliva flow.
  • Stones (Sialolithiasis): Accumulation of minerals forming stones that block the salivary duct, leading to swelling and sometimes infection.
  • Tumors: Benign or malignant growths can cause swelling. The majority of parotid tumors are benign.
  • Autoimmune Diseases: Conditions like Sjogren’s syndrome, which specifically targets and damages salivary glands.
  • Chronic Illnesses: Diabetes and sarcoidosis, among others, might indirectly affect the parotid glands.
  • Dehydration and Poor Nutrition: Lack of fluid intake and malnutrition can affect the salivary glands.
  • Medication Side Effects: Some drugs can cause swelling in the salivary glands, including those used for blood pressure, psychiatric conditions, and chemotherapy.
  • Trauma or Surgery: Injury or surgical procedures near the gland might lead to temporary or persistent swelling.

How is Parotitis Diagnosed?

Clinical Examination

A healthcare provider will first conduct a thorough clinical examination. They will look for signs of swelling, tenderness, redness, and pus discharge. They might also gently massage the gland to check for the release of pus or saliva from the duct.

Medical History Review

Understanding the patient’s medical history, recent illnesses, medication usage, and general lifestyle habits is crucial.

Laboratory Tests

  • Blood tests: Elevated white blood cell count may indicate infection.
  • Culture: If there’s pus or discharge, a culture test can identify the type of bacteria or virus causing the infection.


  • Ultrasound: An ultrasound can help visualize stones, tumors, or inflammation in the gland.
  • MRI and CT Scans: These are often used if a tumor is suspected or to get a detailed view of the gland and surrounding structures.


A dye is injected into the gland, and X-rays are taken. This process helps visualize the salivary duct system. For suspected tumors, an Fine Needle Aspiration (FNA) biopsy can be performed to analyze the types of cells in the swelling.

What Virus Causes Parotitis?

The most common viral cause of parotitis is the mumps virus. Mumps used to be a prevalent childhood disease before the introduction of the MMR (Measles, Mumps, and Rubella) vaccine. Other viruses that might lead to parotitis include HIV, Coxsackie virus, and influenza.

Is Parotitis Contagious?

The contagiousness of parotitis depends on its cause:

  • Viral Parotitis (like mumps): Yes, it is contagious. Mumps is spread through droplets from a person with mumps when they cough, sneeze, or talk. It can also spread by sharing utensils or cups.
  • Bacterial Parotitis: It is typically not contagious unless there is pus discharge from the duct into the mouth, and another person comes into direct contact with it. However, it’s generally not spread through casual contact.
  • Non-infectious Parotitis: Conditions like autoimmune-related or drug-induced parotitis are not contagious.

Prevention Measures for Parotitis

  • Vaccination: Keeping up with vaccinations, especially the MMR vaccine, is crucial.
  • Hygiene Practices: Regular hand washing, not sharing utensils, and practicing good oral hygiene can prevent the spread.
  • Staying Hydrated: Adequate water intake helps maintain saliva flow, preventing bacterial overgrowth in the gland.

Treatments for Parotitis

Treatment for parotitis depends largely on the underlying cause.

For Viral Parotitis

Mumps: Since there’s no specific treatment for mumps, the approach is symptomatic relief. Patients are advised to get plenty of rest, stay hydrated, and use pain relievers like acetaminophen or ibuprofen to ease the discomfort.

For Bacterial Parotitis

  • Antibiotics: The first line of treatment is often antibiotics. The specific antibiotic prescribed depends on the type of bacteria causing the infection.
  • Drainage: In cases where an abscess forms, it might need to be drained.

For Chronic or Recurrent Parotitis

  • Sialogogues: These are agents that stimulate the flow of saliva, like sour candies or medications.
  • Sialendoscopy: This is a minimally invasive technique used to visualize, diagnose, and treat diseases of the salivary duct system.
  • Warm Compresses and Massage: Applying warm compresses and gently massaging the gland can promote saliva flow and relieve symptoms.

For Non-Infectious Causes

Treatment varies and might involve managing underlying conditions, changing medications, or other interventions based on the specific cause of the parotitis.

Preventing Parotitis

Prevention strategies depend on the type of parotitis:

  • Vaccination: For viral parotitis like mumps, getting vaccinated with the MMR vaccine is the most effective prevention.
  • Oral Hygiene: Regular and thorough oral hygiene practices can prevent bacterial parotitis. This includes brushing, flossing, and using an antiseptic mouthwash.
  • Hydration: Staying hydrated helps maintain healthy saliva flow, reducing the risk of infections.
  • Avoiding Irritants: Tobacco and alcohol can irritate the salivary glands. Reducing or eliminating their use can be beneficial.
  • Regular Dental Check-Ups: Routine dental visits can help identify and address potential issues early, including those that might lead to parotitis.

What to Expect with Parotitis

During Treatment

  • Medication: If it’s bacterial, you’ll likely be prescribed antibiotics. Adhere to the full course of medication, even if you start to feel better before it’s finished.
