Salivary Gland Disease Flashcards
What are the salivary gland diseases?
- Mucocele/Ranula
- Sialolithiasis
- Acute and Chronic Sialadenitis
- Xerostomia
- Benign Lymphoepithelial lesion (BLEL)
- Sjoren syndrome
- Necrotizing sialometaplasia
- Salivary gland Neoplasia
What is a mucocele/Ranula?
A ruptured salivary duct in which mucin spills into the surrounding tissues.
What is a common cause of oral swelling?
mucocele/ranula
Muccocele/ranula is most often seen in whom?
Children and young adults-but all ages
Where in the oral cavity is a mucocele/ranula seen?
lower lip, buccal mucosa, ventral tongue floor of mouth
Where is the most common site and how often?
- lower lip near #22,27.
- 82% of the time
What are the clinical features of a mucocele/ranula?
-non-tender, soft swelling
-flucuant or firm
-translucent to blue color
-history of repeated swelling and reslolution-superficial
mucocele erupts on own.
Where is a ranula most often located and what is the appearance compared to mucocele?
-located on anterior floor of mouth (FOM) right or left to
midline.
-It appears larger than mucocele
Histopathologically, what is its appearance?
- extravasated mucin
- granulation tissue
- variable mounts of inflammatory cells
How do you treat a mucocele/ranula?
- microscopic exam to rule out neoplasm
- some resolve with no tx
- excision of mucous deposit including involved gland
- marsupilization-unroofing
What is the prognosis for a mucocele/ranula?
- excellent
- occasionally recur if involved gland not excided
What are Sialolithiasis?
- Salivary duct stone
- calcified structures that develop within the salivary ductal system
- Deposition of calcium salts around nidus of debris in lumen
- Cause unclear,may be promoted by chronic sialadentitis and partial duct obstruction
How do Sialolithiasis appear clinically?
- Hard submucosal mas in soft tissue
- may or may not have symptoms
- May have swelling prior or during meals
What is the most common affected gland and how often?
- submandibular gland
- 80% of the time
-can also be affect the parotid or minor glands
What does sialolithiasis like radiographically?
soft tissue appears opaque and lamellated
What is the histological appearance of a sialolithiasis?
- concentric laminations surrounding nidus of amorphous debris
- if associated duct is removed, often demonstrate squamous metaplasia
- periductal inflamation
- acute or chronic sialadenitis of the feeding gland
What is the treatment for sialolithiasis?
-gentle message toward orifice
-sialogogues or sour sugarless candies
-moist heat
-“flush”-increase fluid intake
-surgical removal, may include gland if significant
inflammatory damage
-Lithotripsy, sialendoscopy w/basket retrieval (major
gland)
What is the prognosis for sialolithiasis?
-Minor glands-good
-Major glands-good, but morbidity if gland needs
removal.
What is Acute/Chronic Sialadenitis?
inflammation of the salivary gland
What infectious causes of sialadenitis?
- Bacterial - penicillanase-producing staph
- Viral - mumps
What are non-infectious causes of sialadenitis?
- Ductal obstruction, retograde infection - associated with xerostomia, may follow general anesthesia.
- Chronic may follow acute sialadenitis due to ductal damage.
What are the clinical features/ symptoms of sialadenitis?
- diffuse, painful and tender, unilateral swelling
- pain, especially around meal times
