operation to remove tongue tumour/related tissues
commando op: side of tongue, musc. floor of mouth, mandible, cervical nodes, sternomastoid, int. jug. vein
repair after tongue tumour op?
myocutaneous flap and bone from chest 5th rib – mandible, pec major – musc. for floor of mouth, skin – fl. of mouth
anterior 2/3, tip lymph drainage
submand-deep cervical. submental-submand, deep cerv.
if tumour of tongue more posterior, then what nodes?
more posterior tumour is, will involve nodes higher up.
tongue tumour spread?
soft palate, floor of mouth, mandible, posterior 1/3, tonsil
superior and middle thyroid veins drain where
internal jugular
inferior thyroid vein drains where
left brachiocephalic
superior pharyngeal constrictor innervation, mid, inf.

hyoid bone
structures at risk during carotid reaming out
endarterectomy: vagus (laryngeals), hypoglossal
methods for reducing emboli
blood thinners, aspirin
when small emboli pass through cerebral vessels
platelets/lipids: cause transient ischemic attacks – usually on same side/structure (bloodflow=laminar) sudden loss of vision, sudden weakness, vertigo. HARBINGER: bad things
what is a carotid clamp for?
if huge middle cerebral aneurism, need to reduce flow: danger of bleeding. put small clamp (tap) on carotid, gradually reduce to ensure enough collateral flow elsewhere before turning off entirely

causes of eye swelling
tumours, infection from sinuses, vessel malformations, lymph swelling, endocrine disease (hyperthyroid)
choroid plexus tumour
will fill in ventricles, create lesion, bulge gyri
space occupying lesion in brain – effect
coning – brain shifts to accommodate, may herniate through dura, disturb resp. patterns, compress cerebellum/brainstem
fracture of frontal sinuses – danger
