Flashcards in Module 2_Examination 1 (Head and neck Exam) Deck (23):
1

What consists of the first part of the examination?

-Head, jaw, neck (general appearance)

-Muscles of mastication

-Jaw opening

-TMJ

-Blood vessels
-Salivary Glands
-Lymph system

second part= cranial nerves

2

What are the steps to the exam?

-Look at the head and neck in both frontal and sagittal views-->check for abnormalities and asymmetries

3

Where should you look to differentiate between Crouzon's and Apert's syndrome?

Hands

4

How should the temporalis muscle be palpated extra orally?

-Anteriorly to posteriorly
-Check for tender spots

5

How should the masseter be palpated extra orally?

-Insertion (zygomatic arch)-->body of muscle with jaws clenched and unclenched-->attachment to angle of mandible

6

Where is the medial pterygoid palpated extra orally?

Under the angle of the mandible

7

Where is the temporalis palpated intra orally?

Coronoid process

8

Where is the medial pterygoid palpated intra-orally?

Ramus of the mandible

9

Where is the lateral pterygoid palpated?

Behind the maxilla

10

What technique should be used in palpating muscles? Why?

-Bilaterally simultaneously
-Allows patient to tell you if any difference between right and left side

11

What aspects should be measured in terms of jaw opening?

-Patient should open as wide as they can
-Then close
-Then swing left
-Then swing right
(movements should be smooth and symmetrical)

Jaw opening distance should be measured (by using ruler to measure interincisal gap)

Lateral movement distance measured using the mx and md midlines as landmarks

12

What is the normal range of jaw movement? When should you refer a patient?

Opening: 45mm +
Lateral: 6-8mm +
*Refer if opening less than 25mm

Patient who can't open more than 5mm is in life threatening situation
10mm: serious difficulty
20mm: difficult to eat or dental treatment

13

How should TMJ Examination be performed?

-Palpate TMJ on opening and closing-->should feel rotation and translation
-Normally symmetrical
-Note any crepitus or catching

-Stretch test
-Get pt to open halfway
-Push sharply downwards on chin
-If muscles cramped will feel soreness along muscle lines
-If TMJ inflamed will hurt in TMJ and ears

Neck muscle evaluation
-Palpate sternocleidomastoid
-Palpate occipital muscles
-Get patient to rotate head left and right-->should be symmetrical and pain free
-Get them to also tilt up and down with head in the midline

14

What blood vessels should be checked?

Facial artery (including superior and inferior labial arteries)

Facial vein

Auriculotemporal/superfical temporal artery (note runs deep and posterior to TMJ, can be palpated as it crosses zygomatic arch between external acoustic meatus and condyle))

External carotid (bit above Sternocleidomastoid)

Visually examine if another discoloration or swelling following facial vessels
Palpate arteries for abnormalities and pulses

15

What should be checked on salviary gland exam? What technique shoudl be used?

-Parotid (behind masster and mandibular ramus)
-Submandibular gland (near angle of the jaw)
-Sublingual gland (floor of the mouth)

Bimanual palpation
One hand on outside of mouth push gland up
one hand inside and push down
Feel gland between two fingers
*Compare both sides

16

How to differentiate between parotid and masseteric swelling?

-Get patient to clench
-If parotid will not change

17

What is an enlarged single sublingual gland likely to indicate?

-Mucoepidermoid carcinoma

18

Is it normal to feel the submandibular gland via palpation?

-Can not feel normal submandibular gland
-Also should not be tender

19

What is the characteristic of an inflamed gland/

-Swollen
-Tender
-Tense

20

What is the characteristic of a neoplastic gland?

-Enlarged
-Non-tender
-Hard

21

How should you carry out a lymph node exam?

Submental
Submandibular
Facial (anterior to the masseter muscle near the facial artery)-->enlarged and tender if mouth inflamed-->always enlarged if wisdom teeth extracted
Jugulodigastric (important to check in oral cancer patients)

22

What portion of hte body's lymph nodes are in the head and neck?

Half

23

How do you differentiate between inflamed, malginant and developmentally swollen lymph nodes?

Inflamed:
-Tense and tender

Malignant:
-Very hard and painless

Developmental:
-Present for a long time
-Soft
-Non-tender
