PAROTITIS
(OR)
DEFINITION:
Parotitis is inflammation of the parotid salivary gland. Inflammation results in swelling of the
tissues that surround the salivary glands, redness, and soreness.
TYPES OF PAROTITIS:
Based on the onset:
Acute
Chronic
Chronic with acute exacerbation
Based on the causative agents:
Bacterial parotitis
Viral parotitis
CAUSATIVE AGENT:
Staphylococcus aureus is the most common bacterial pathogen
Viral parotitis is more common worldwide than bacterial parotitis with mumps
being the most common viral cause of parotitis in children.
PREDISPOSING CONDITIONS:
Dehydration
Malnutrition
Immunosuppression
Dental infections
Tracheostomy
Medications that suppress salivary flow (antihistamines, diuretics, anticholinergic
medications)
PATHOPHYSIOLOGY
Acute bacterial
Bacteria spread from the oral cavity parotid gland (via Stensen's duct-
the main excretory duct of the parotid gland).
Another potential mechanism, especially in newborns, is hematologic spread from
transient bacteremia
Chronic bacterial
Chronic bacterial parotitis may exist in the presence of calculi or
stenosis(narrowing) of the ducts secondary to injury and is less likely as a sequela
(prior disease or injury)of acute bacterial infection.
In most instances, the chronic disease is autoimmune with superimposed bacterial
infections.
Signs and Symptoms:
Face pain
Fever
Headache
Sore throat
Loss of appetite
Swelling of the parotid glands (the largest salivary glands, located between the ear and the
jaw)
Swelling of the temples or jaw (temporomandibular area)
Other symptoms
in males are:
Testicle lump
Testicle pain
Scrotal swelling
DIAGNOSTIC EVALUATIONS
Cultures: may be obtained from parotid needle aspiration
Ultrasound: demonstrates solid masses or fluid collections within the gland
CT scanning and MRI: with gadolinium enhancement(contrast) may be used to determine
the size, shape, and presence of a neoplasm or abscess within the gland
MANAGEMENT
Adequate hydration
Ice or heat packs
Eat soft food
Gargle with warm salt water
Medical Management:
antimicrobial therapy
Antibiotics should be administered intravenously
antistaphylococcal antibiotic (nafcillin, oxacillin, cefazolin).
Cefoxitin, imipenem, ertapenem, the combination of penicillin plus beta-lactamase
(amoxicillin/clavulanate, ampicillin/sulbactam).
Vancomycin, linezolid, or daptomycin.
In penicillin-allergic patients, clindamycin is an alternative option
Surgical Management
Surgical drainage and decompression of the gland are occasionally required if spontaneous
drainage does not occur
Parotidectomy may eventually be required for people with long-standing infection
Prevention
MMR immunization (vaccine) protects against measles, mumps, and rubella.
It should be given to children at these ages:
First dose: 12 through 15 months old
Second dose: 4 through 6 years old
Adults can also receive the vaccine.
