Salivary Gland Ds Flashcards
The largest of the salivary glands and is predominantly serous with few
scattered mucous acini.
- Produces most stimulated saliva
Parotid gland
What is the stetson’s duct?
Parotid gland opening into oral cavity
Below/anterior EAC (External
Acoustic Meatus)
Posterior to mandibular ramus
and anterior to mastoid process
or temporal bone
Parotid gland
_____ Nerve is embedded within the superficial and deep lobes of
the parotid gland.
Facial nerve
It is a large salivary gland composed of a mixture of serous and mucous
acini.
Located in Submandibular triangle
Submandibular gland
What is the wharthin’s duct?
Submandibular gland opening around lingual frenum
Submandibular gland divided
into superficial and deep
lobes separated by
______
mylohyoid muscle.
The superficial lobe of
the submandibular gland is in
the submandibular space, and
the deep lobe is situated in
the sublingual space where it
can be palpated intraorally.
Submandibular gland
It is the smallest of the major salivary glands.
It is almond-shaped and lies beneath the mucous membrane of the floor
of the mouth close to the midline.
It is a mucous-secreting gland.
Sublingual gland
Located on superior surface of mylohyoid muscle and separated from
oral cavity by thin later of mucosa
Sublingual gland
_______ ducts (sublingual) consist of 8-20 smaller ducts called as Ducts of Rivinus
empties into floor or mouth near the punctum of Whartons ducts or on a crest
of sublingual mucosa called plica sublingualis or directly into Wharton’s
duct.
Bartholin’s ducts
(Increase in saliva flow)
- Psychosis
- Mental retardation
- Certain neurological diseases
- Rabies
- Mercury poisoning
Sialorrhea
(Decrease in saliva flow)
- Mumps
- Sarcoidosis
- Sjoegrens syndrome
- Lupus
- Post-irradiation treatment.
Xerostomia
(Most Common and often recurrent benign salivary gland tumor
Pleomorphic adenoma
Most common salivary gland malignancy
Mucoepidermoid tumor
Which salivary gland tumor has perineural spread?
Adenoid cystic carcinoma
Mechanical usually unilateral
diffuse glandular swelling
Sialolithiasis
Mechanical obstruction usually causes unilateral diffuse glandular swelling
Salivary Calculi/ Stones (Sialolithiasis)
Which gland are salivary stones most commonly found?
Submandibular
_______ is the radiographic examination of the salivary glands.
It usually involves the injection of a small amount of contrast medium into
the salivary duct of a single gland, followed by routine X-ray projections.
Sialography
Performed with stone is palpable within distal segment or anterior region of
whartons duct in submandibular gland.
Stone can be removed transorally if in the duct and easily palpable
-Don’t close the duct: leave open to avoid stenosis
Transoral Sialolithotomy with Sialodochoplasty
___________ is an image-guided technique
for the evaluation and treatment of patients with obstructive disease of the
salivary glands.
Sialoendoscopy (salivary gland endoscopy)
Where do mucoceles mostly occur?
Lower lip
How do you avoid recurrence of mucoceles?
Excise the lesion and removal of adjacent minor salivary glands
A _______ usually presents as a translucent blue, dome
shaped, fluctuant swelling in the tissues of the floor of the mouth.
Obstruction disorder usually involves the Sublingual gland
Consist of mucin from rupture salivary gland
Etiology: usually trauma to duct or gland
Common in children
Usually asymptomatic with exception to elevation in floor of mouth
ranula
What two glands are usually affected in ranula?
Sublingual (mostly) and Sub mand
How do you treat renula?
Removal of affected gland; can marsupialize too
_____ ranulas dissect thru mylohyoid to produce swelling in the neck
Plunging/cervical
How do you treat plunging/cervical ranula?
Remove glands: subling or submand or both
________ is an inflammation of gland or duct. Inflammation of the
salivary glands can arise from various infectious and non-infectious causes.
– Obstruction,
– Bacterial infection (acute vs chronic),
– Viral (HIV, Mumps)
– Sarcoidosis,
– Sjogrens syndrome,
– Tumor,
– Irradiation,
– Malnutrition
Most bacterial infections arise as a result of ductal obstruction or
decreased salivary flow
One of the more common causes is recent surgery
Sialadenitis
Is bacterial or viral Sialadenitis more common?
Bacterial
