Salivary Glands Pathology (Non-Neoplastic) Flashcards
Stafne’s bone cavity (defect)
Developmental condition
- Traditionally thought to be developmental inclusion of submandibular salivary gland along lingual cortex of Md
Symptoms and radiographic presentation of Stafne’s bone cavity
No signs or symptoms
Radiolucency, often corticated, below the inferior alveolar canal and roughly from angle to midbody
Treatment of Stafne’s bone cavity
No treatment, recognition only
Not pathology!
Mucocele
Traumatic severance of salivary duct resulting in mucus extravasation into connective tissue, not epithelial lined
- Not a cyst
Location where mucoceles commonly occur
Lower lip
Lateral tongue
Ant. ventral tongue
Cheek
What age group do mucoceles occur in
Kids and young adults
“the younger you are, more active you are, more chance for injury”
Ranula
Mucoceles in floor of mouth
usually lateral to the midline
Polunging (cervical) ranula
spilled mucin dissects through the mylohyoid muscle, producing swelling in neck. Can be potentially serious
Salivary Duct Cyst
also known as mucus retention cyst
- True epithelial lined cyst from salivary duct
- Bluish (or normal color) soft fluctuant swelling
Demographic pattern of Salivary Duct cyst
Mostly in adults
Occurs in major and minor glands, can be multiple
Most common location of Salivary Duct Cyst
Parotid gland, **Palate (most common), FOM, Buccal mucosa, lips
Sialolith, Sialolithiasis
(salivary stones)
- Calcifications in salivary duct
- *NOT due to hypercalcemia
Where are Sialoliths most common
Most often in submandibular gland
Also in minor glands, upper lip, buccal mucosa
Symptoms and radiographic features of Sialolith
Pain or swelling especially at meal time
Radiograph +-, sialography, ultrasound, CT
TX of Sialolith
Gentle massage, increase fluid intake, moist heat, sialogogue, surgery
Mumps
(Epidemic Parotitis)
Paramyxovirus infection primarily affect the salivary glands
- Also targets gonads. Esp. in boys it can produce sterility
