. It may be subdivided temporally into acute, chronic and recurrent forms.
Alternate spelling:Sialoadenitis

Acute Form

Predisposing factors:

• decreased flow (dehydration, post-op, drugs)
• poor oral hygiene
• exacerbation of low grade chronic sialoadenitis

Clinical features:

• Painful swelling
• Reddened skin
• Oedema of the cheek, Periorbital region and neck
• low grade fever
• malaise
• raised ESR, CRP, leucocytosis
• purulent exudate from duct punctum

Chronic Form

Clinical Features:

• unilateral
• mild pain / swelling
• common after meals
• duct orifice is reddened and flow decreases
• may or may not have visible/palpable stone.
• Parotid gland
  Parotid gland
  The paired parotid glands are the largest of the salivary glands. They are each found wrapped around the mandibular ramus, and secrete saliva through Stensen's ducts into the oral cavity, to facilitate mastication and swallowing and to begin the digestion of starches.-Location:The parotid glands...
  
  
  • Recurrent painful swellings
• Submandibular gland
  Submandibular gland
  The paired submandibular glands are salivary glands located beneath the floor of the mouth. In humans, they account for 70% of the salivary volume and weigh about 15 grams. Unstimulated in humans, the percentage contribution to whole saliva; ~25% Parotid, Submandibular and Sublingual ~ 67% and...

    Sialolithiasis
    Sialolithiasis refers to the formation of stones in the salivary glands. Stones are most commonly found in the submandibular gland, where stones can obstruct Wharton's duct...
    
    or stricture

Treatment:
antibiotics that cover oral flora (Augmentin or Clindamycin)
Steroids for swelling and inflammation
Sour candy and foods to stimulate saliva excretion
Pain control
