Salivary Gland Disorders
Salivary gland disorders include inflammatory, bacterial, viral and neoplastic causes.

The presentation can be acute, recurrent, or chronic.

Acute suppurative sialadenitis presents as rapid-onset pain and swelling and is treated with antibiotics, salivary massage,
hydration and
sialagogues (agents that increase the secretion of saliva) such as lemon drops or vitamin C lozenges.

Viral causes include mumps and Human Immunodeficiency Virus and treatment is directed at the underlying disease.

Recurrent or chronic
sialadenitis is more likely to be inflammatory than infectious; examples include recurrent parotitis of
childhood and
sialolithiasis (salivary stones).

Inflammation is commonly caused by an obstruction such as a stone or duct stricture.  Management is directed at relieving
the obstruction.

Benign and malignant tumours can occur in the salivary glands and usually present as a painless solitary neck mass.  
Diagnosis is made by imaging (e.g., ultrasonography, computed tomography, magnetic resonance imaging) and biopsy
(initially with fine-needle aspiration).  Overall, most salivary gland tumors are benign and can be treated with surgical excision.
