Ent - Salivary Gland Disease

Front 1

Describe the parasympathetic function of the facial nerve.

Back 1

Innervation to lacrimal gland as well as submandibular and sublingual salivary glands.

Front 2

Does the facial nerve innervate the parotid gland?

Back 2

No!

Though the facial nerve runs through the parotid gland, the parotid itself is innervated by the auriculotemporal nerve.

Describe the functions of the facial nerve.

Back 3

1) Motor
-facial muscles

2) Sensory
-taste from anterior 2/3 of tongue, external auditory canal, external ear

Front 4

Back 4

Front 5

Which nerve detects taste in the anterior 2/3 of the tongue?

Back 5

Front 6

How can Bell's palsy be differentiate from a central lesion in a patient with facial paralysis?

Back 6

Sparing of the forehead suggests central lesion.

Front 7

Back 7

Pleomorphic adenoma

Front 8

What is the second most common benign salivary tumour?

Back 8

Warthin's tumour

Front 9

What is the most common malignant salivary gland tumour?

Back 9

Mucoepidermoid carcinoma

Front 10

Give a differential diagnosis for a mass in the region of a salivary gland.

Back 10

1) Benign and malignant neoplasms of the salivary gland
-benign: pleomorphic adenoma, Warthin's tumour, salivary cyst
-malignant: mucoepidermoid carcinoma, squamous cell carcinoma

2) Lymphadenopathy
