venous drainage

A

retromandibular vein

43
Q

retromandibular vein

A

formed from superficial temporal and maxillary veins

anterior and posterior division

44
Q

anterior retromandibular vein

A

merges with facial - common facial vein

45
Q

common facial vein

A

to internal jugular vein

from anterior retromandibular and facial vein union

46
Q

posterior retromandibular vein

A

merges with posterior auricular vein - external jugular vein

47
Q

external jugular vein

A

from posterior auricular and posterior retromandibular veins

48
Q

lymph drainage

A

submental, submandibular, parotid nodes

ultimately, to deep cervical nodes

49
Q

danger area

A

central face area

-infection travel from superficial to deep face or skull

50
Q

facial vein communication

pterygoid plexus via deep facial vein

cavernous sinus via ophthalmic veins

51
Q

parotid gland

A

largest of salivary glands

-overlying ramus of mandible

52
Q

parotid duct

A

crosses masseter

-enters oral cavity opposite 2nd upper molar

53

within parotid gland (parotidectomy be careful)**

A

facial nerve
retromandibular vein
external carotid artery

55
Q

parasympathetic to parotid

-exits foramen ovale - synapse on otic ganglion

postganglion - fibers with auriculotemporal branch V3

56
Q

sympathetic to parotid

A

preganglionic - T1-4
-postganglionic SCG
