16
Q

Describe the facial artery’s course

A

Tortous course to the medial angle of the eye giving branches to the upper/lower lip and cheek and nose.

17
Q

What is the arterial supply between the face and scalp

A

Branches of the external carotid, posterior auricular artery and occipital artery

18
Q

What is the venous drainage of the face?

A

Facial vein

19
Q

What is the venous drainage of the scalp?

A

The veins accompanying the external carotid

20
Q

What is the significance between the communications between the facical veins and cavernous sinuses?

A

The fact that infections can travel through this area.

21
Q

What is the parotid gland?

A

Serous salivary gland

22
Q

Where is the parotid gland located?

A

beneath the zygomatic arch in front of the mastoid process above the angle of the mandible behind the mastica, superficial to the syloid process.

23
Q

What is the parotid gland contained in?

A

Parotid fascia

24
Q

What is the significance of the parotid fascia?

A

In mumps the parotid gland becomes inflammed against the fibrous capsule causing intense pain

25
Q

Where is the duct of the parotid gland?

A

The duct emerges from the anterior border of the parotid gland running across the masseter. Once it reaches the inferior edge of masseter it turns inwards and pierces buccinator and enters the cavity just near the second upper molar.

26
Q

Where does the facial nerve exit?

A

Stylomastoid foramen

27
Q

Where does it enter the parotid gland?

A

Posteromedial surface

28
Q

What is the plexiform arrangement called in the parotid gland?

A

PES ANSERINUS

29
Q

What does the facial nerve supply?

A

Occipitalis via posterior auricular branch
Posterior belly of the digastric
Stylohoid muscle

30
Q

What does the facial nerve do after emerging from the anterior border of the parotid gland?

A

It fans out forming 5 branches

31
Q

What are the branches of the facial nerve (VII)?

A 
Temporal
Zygomatic
Buccal
Mandibular
Cervical
32
Q

What is the venous drainage from the parotid gland?

A

Retromandibular vein

33
Q

What is the arterial supply to the parotid gland?

A

External cartoid artery

34
Q

What is the clinical significance of the facial nerve in the parotid?

A

If damage the facial nerve, deinnervation can occur.

35
Q

What is bells palsy?

A

Drooping of lower eyelid, angle of mouth and flattening of facial folds
