Study Notes

Salivary Glands

Salivary glands are exocrine glands that produce saliva through a system of ducts.
Two types of salivary glands exist: major and minor.
Major salivary glands are the largest and most important, producing most saliva in the mouth.
Three major salivary glands: submandibular glands, parotid glands, and sublingual glands.
Sublingual glands are paired, located in the anterior part of the mouth floor. Each has numerous excretory ducts opening into the oral cavity.

Disorders of Sublingual Glands

Ranula: a mucous retention cyst that can arise from the sublingual salivary gland, forming under the tongue and filled with saliva leaked from a damaged salivary gland.
Causes of ranula: saliva is unable to drain directly into the mouth if the sublingual gland is injured or diseased. Saliva leaks into surrounding tissues, forming a ranula.
Presentation: painless swelling in the submandibular or submental region of the neck.

Submandibular Glands

Paired salivary glands located below the mandible (jawbone) on each side.
8% of all salivary stones occur in submandibular glands because their secretions are highly viscous.
8% of submandibular stones are radio-opaque and can be identified on plain radiography.
Common causes of submandibular gland inflammation (sialadenitis): viral (paramyxovirus) and bacterial. Bacterial is more common and secondary to obstruction.
Common cause of obstruction: stone formation within the gland and its associated duct system

Clinical Symptoms of Sialadenitis

Patients typically present with acute painful swelling in the submandibular gland area.
Swelling often occurs rapidly after eating and resolves spontaneously within 1-2 hours.
Clinical examination reveals enlarged, firm, and tender submandibular glands. Pus may drain from the sublingual papilla.
Partial or complete obstruction of the submandibular duct is often involved. Stones are a frequent cause.

Parotid Glands

The parotid gland is divided into deep and superficial lobes, separated by the facial nerve.
Mumps is the most common cause of acute painful parotid swelling in children, spread via airborne droplets of infected saliva.
Mumps typically starts with fever, nausea, headache, followed by pain and swelling in one or both parotid glands. Pain can be severe and exacerbated by eating or drinking.
One episode of infection confers lifelong immunity.

Sjogren's Syndrome

Unknown etiology, but genetic, hormonal, infectious, and immunologic factors may be involved. Immunologic mechanisms are a primary factor.
Clinically, predominately affects women over 40, with a female-to-male ratio of 10:1.
Commonly presents with dry eyes and dry mouth due to hypofunction of lacrimal and salivary glands, resulting in pain, burning sensations, and ulcerations on the oral/conjunctival mucosa.
Sialography demonstrates cavitary defects filled with radiopaque contrast media, exhibiting a "branchless fruit laden tree" or "cherry blossom" appearance. Sjogren's involves biopsy

Frey's Syndrome (Gustatory Sweating)

A condition characterized by sweating and sometimes flushing of the skin in the area of distribution of the auriculotemporal nerve.
Thought to result from damage to the auriculotemporal nerve, where postganglionic parasympathetic fibers from the otic ganglion unite with sympathetic fibers from the superior cervical ganglion to supply sweat glands in the skin.
The syndrome can occur after surgery of the parotid gland, TM joint, injuries to the face region, or injections into this area.
Treatment for persistent cases may involve botulinum type A injections.
