Understanding the Condition
Parotitis is inflammation of one or both parotid glands, most often caused by infection, blockage or an immune condition. The parotid glands are located anterior to the ear and play a key role in saliva production. Inflammation occurs when normal salivary flow is disrupted or when infectious or immune-mediated processes affect glandular tissue.
Parotitis may be unilateral or bilateral, depending on the underlying cause.

Classification
Parotitis encompasses several distinct clinical entities, each requiring a different management strategy.
Rapid onset of pain, swelling, and sometimes systemic symptoms such as fever.
Persistent or intermittent swelling from repeated infections or ductal obstruction.
Cyclical episodes of swelling indicating ductal abnormalities or incomplete resolution.
Sjögren's syndrome and other inflammatory disorders affecting glandular tissue.
HIV-related salivary gland disease with parotid enlargement and cystic changes.
Etiology
Parotitis may arise from several underlying mechanisms:
Bacterial infection (commonly due to ductal stasis) and viral infections such as mumps.
Salivary stones and ductal narrowing or strictures.
Sjögren's syndrome and other inflammatory disorders affecting glandular tissue.
Dehydration, medication effects, and radiation therapy.

Signs & Symptoms
Symptoms vary depending on the underlying etiology and severity of inflammation:
Painful swelling near the ear or jaw
Redness or warmth over the gland
Dry mouth or reduced saliva
Difficulty chewing or swallowing
Fever in infectious cases
Precision Diagnostics
A detailed history and physical examination help distinguish between acute, chronic, and recurrent forms of parotitis.
Detailed history and physical examination to identify the form and underlying cause of parotitis.
Ultrasound for initial evaluation, CT or MRI for deeper or complex disease.
Sialendoscopy allows for direct visualization of the salivary ducts and identification of obstruction or inflammation.
Targeted Therapy
Treatment is guided by the underlying cause and severity of disease.

Antibiotics for bacterial infection, hydration and gland massage, and anti-inflammatory therapies.
Sialendoscopy plays an important role in managing obstructive and chronic inflammatory parotitis by restoring ductal patency.
Chronic parotitis may require repeated interventions or targeted therapies to prevent recurrence and preserve gland function.
Our Approach
Successful treatment depends on identifying and correcting the root cause of inflammation rather than treating symptoms alone.
Whenever possible, interventions are designed to maintain salivary production and avoid gland removal.
Long-term management strategies focus on preventing repeated episodes and progressive gland damage.


Don't Wait
Early specialist involvement improves diagnostic accuracy and expands treatment options. Seek evaluation if you experience:
Recurrent or persistent gland swelling
Severe or worsening pain
Symptoms not responding to initial treatment
Associated dry mouth or systemic disease
PATIENT EDUCATION
Parotitis is inflammation of the parotid gland, which can be caused by bacterial infection, viral infection (such as mumps), autoimmune disease, or duct obstruction.
Viral parotitis (such as mumps) can be contagious. Bacterial and obstructive parotitis are not contagious as they are caused by internal factors.
Treatment depends on the cause and may include antibiotics for bacterial infection, anti-inflammatory medications, hydration, gland massage, and in some cases, minimally invasive procedures to address duct obstruction.
Yes. Recurrent parotitis is a recognized condition, particularly when caused by underlying duct abnormalities, stones, or autoimmune disease. Identifying the root cause is essential for prevention.
Seek urgent evaluation if you experience rapidly worsening swelling, high fever, difficulty opening the mouth, or signs of abscess formation.

Why Choose OHNI
Many patients assume the best care is found at large, well-known institutions. While these centers offer excellent care, they often operate within standardized systems shaped by regional training models.
At OHNI, Dr. Ryan Osborne offers something fundamentally different: a truly global perspective combined with highly personalized surgical care with experience across five continents, tailoring each procedure to the individual patient, not the system.
Experience across five continents, applying diverse surgical philosophies and techniques beyond standard U.S. training.
Specialized techniques like Extra-Capsular Dissection designed to minimize invasiveness while protecting the facial nerve.
Direct surgeon access, individualized treatment planning, and a focus on both medical outcomes and quality of life.
Patients consistently highlight clear communication, confident surgical decisions, and excellent functional results.
By identifying the underlying cause and applying targeted therapies, including minimally invasive techniques, most patients can achieve significant symptom relief and preservation of gland function.
