Veins of H&N Flashcards
What are the major face veins
Which veins drain into the facial vein
Angular
Superior labial
Inferior labial
Which veins does the facial vein connect with and where do they drain into
Infraorbital veins which drain into pterygoid venous plexus
What is the potential risk of veins of the face draining into the cavernous sinus and pterygoid venous plexus
Chance that infection may spread from the face to the sinsuses as the veins are valveless
Where do veins of the scalp drain into and what do they drain through
They drain into the dural venous sinuses through emissary veins
What are the dural venous sinuses
Venous channels found between endosteal and meningeal layers of dura matter
Cerebral veins drain into them
Name the dural venous sinuses
Superior and inferior sagittal
Straight
Confluence of sinuses
Transverse
Sigmoid
Cavernous
What is the cavernous sinus
Venous plexus on the upper surface of the sphenoid
It forms part of the intracranial venous system
What is contained within the cavernous sinus
Internal carotid artery
CN III/oculomotor
CN IV/trochlear
CN VI/adbucent
CN V1/opthalmic
CN V2/maxillary
Describe the passage of the facial vein
Runs from the medial angle of the eye towards the inferior border of the mandible with the facial artery
Then the facial vein drains into the IJV
Which dural venuos sinus continues as the IJV
Sigmoid sinus
Name some veins which drain into the IJV
Facial vein
Veins draining the thyroid and tongue
Which veins does the angular vein connect with and where do they drain
Superior and inferior opthalmic veins which connect with the cavernous sinus
Which dural venous sinus does the facial vein connect directly to
Pterygoid sinus
What artery runs through the cavernous sinus
Internal iliac vein
