Exam 1 - Salivary Glands

Salivary glands are not present on the

gingiva

dorsum of tongue anterior to CV papillae

attached alveolar mucosa

mid-palatine raphe

mucoceles are

reactive

sialorrhea

excessive salivation

sialadentitis

inflammation of salivary glands

causes of sialadenitis

infections

recent surgery

dehydration

debilitation

medication

sialadenosis

non-inflammatory salivary gland enlargement

causes of sialadenosis

endocrine disorders

pregnancy

nutritional conditions

neurogenic medications

what type of lesion is a mucocele (benign, malignant, reactive)

reactive

mucocele characteristics

bluish 

fluctuate in size 

non-blanching (not vascular)

common on lower lip

psuedocyst

demo: kids/young adults

salivary duct cyst

location: major/minor salivary glands

mimics mucocele

true cyst

ranula characteristics

location: floor of mouth

frog underbelly

involves sublingual/submandibular gland

blue

lateral to midline

one of most common soft tissue enlargements

mucocele

sialolith (sialolithiasis)

deposits of calcium salts in salivary gland/duct

sialolith characteristics

Cause: decreased salivary flow OR increased viscosity

Location: submandibular gland/duct

Painful

radioopaque

necrotizing sialometplasia characteristics

ischemic

mimics squamous cell carcinoma

swelling first then concavity

sjogrens syndrome characteristics

female predilection

dry mouth 

dry eyes

enlarged salivary glands

pain/burning

increased candidiasis

salivary gland tumors usually occur in the

parotid gland

salivary gland tumors in the parotid gland ¾ of the time are 

benign 

salivary gland tumors in the parotid gland ¼ of the time are 

malignant

the larger the gland the more likely it is to be

benign

the smaller the gland the more likely it is to be

malignant

the submandibular gland has a ___/___% chance at being benign/malignant

50/50

majority of the time lesions in the sublingual gland are 

malignant

_______ lip lesion is more common to be benign

upper

_______ lip lesion is more common to be malignant

lower

BM/palate have a 50/50% shot at being benign or malignant

true

tongue/retromolar pad/floor of mouth have a very high chance of being benign 

false

what increases the chance of a benign neoplasm turning malignant

no treatment

canicular adenoma

canicular adenoma

female predilection

upper lip

blue
