4. take a top-down approach to assess
5. evaluation criteria
30
what are the ABC's of assessment for facial trauma?
A = airway
B = breathing
C = consciousness (aka mental status)
31
why do you need to manage significant bleeding in the face?
- to better assess all structures (for better visibility)
32
how can you check the nose and ears for CSF?
- halo test with a gauze wad (in the nose or ears, wherever there is bloody drainage)
33
what is the top-down approach to assess facial injuries?
- look for facial asymmetry

- oral cavity and mandible
34
what are the evaluation criteria for facial injuries?
- asymmetry
- bony steps
- bony mobility
- bruising
35
what is the cause of a forehead fracture?

- numbness of the cheek, side of nose, upper lip or ipsilateral teeth (because of injury to the infraorbital nerve)
39
how do you care for an orbital fracture?
- ice
- no blowing nose
- no Valsalva maneuver (keep head upright and limit movement)
- *the risk of infection is high
- x-ray/CT to confirm fracture
- treated surgically or will resolve spontaneously
40
what are the signs of a midface (maxillary) fracture?
-*must also assess the airway and eyes (especially around the nose)
- visible lengthening and flattening of face
- mobile maxilla
- nasal bleeding
- ecchymosis of cheek
- malocclusion (alteration of bite) --> teeth won't go together
41
how do you palpate to confirm a maxillary fracture?
- along maxilla (for major deformities)
- forehead stabilization with one hand, gently pull maxillary incisors (to see if face moves)
42
what are the 3 levels of maxillary fracture?
- Le Fort I = only under nose
- Le Fort II = up cheek bones and top of nose
- Le Fort III = up to top of eye sockets
43
what is the cause of a zygomatic complex fracture?

- double vision (diplopia)
- possible restricted eye movements
- possible subconjunctival hemorrhage and periorbital ecchymosis
45
how can you measure step-offs for a zygomatic complex fracture?
- place a ruler or pencil on the side of the head, should stick relatively straight down
- positive test is if the bottom of the ruler deviates
46
how do you care for a maxillary and zygomatic complex fracture?
- secure airway
- if conscious, keep upright for blood and saliva drainage (not down the throat)
- transport to emergency for diagnosis and imaging
47
what is the cause of a mandible fracture?

- +ve tongue blade test
- deformity
- loss of occlusion
- bleeding around teeth
- lower lip numbness
49
what is the tongue blade test?
- insert a wooden tongue depressor into patients molars
- tell them to bite down
- if you can twist the tongue depressor and it breaks, they likely didn't fracture their mandible
- broken mandible will be weak, painful and likely unable to keep strength in bite
50
how do you care for a mandible fracture?
- secure airway
- immobilize with elastic wrap (around head to keep jaw closed) --> easy to remove in case of vomiting

what are the signs of the three types of tooth fractures?
- uncomplicated = fragments without bleeding
- complicated = bleeding, tooth chamber exposed, pain and sensitivity with air exposure, touch and temperature
- root fractures = requires an x-ray, may feel loose and have bleeding
55
how do you care for tooth fractures?
- uncomplicated and complicated do not require immediate attention (just within 24 hours)
- place broken off pieces into milk or save-a-tooth solution (NOT ON ICE)
- control bleeding with gauze
- for root fractures, follow-up immediately following the game
56

64
how do you manage a tooth avulsion injury?
- locate and protect the tooth
- rinse lightly with milk (if soiled)
- do not rub or rinse with tap water (injures periodontal ligament cells and compromises implantation)
- try to reposition tooth if athlete is conscious (any position is fine, just want to keep viable)
- splint with hand or paper towel to hold in place
- immediate dental evaluation

67
how do you care for nasal fractures?
- secure airway if needed
- control bleeding by external pressure if needed
- internal packing (nose plugs, etc.)
- protect and transport for x-ray, exam and reduction
- will have little problem for return, may fix with surgery (depending on severity and athlete)
68
what is the cause of septal hematoma injuries?
- hemorrhage between the two layers of mucose covering the septum
69
what are the signs of a septal hematoma?
- blueish or dull red bulge on the septum
- nasal pain and difficulty breathing out of one nostril
70
how do you care for a septal hematoma?
- *untreated will lead to abscess and bone cartilage loss and deformity

- insert wick to allow for further drainage
- pack to prevent the return of hematoma (needs pressure)
71
what is the cause of injury of epistaxis?
- *aka nosebleed

73
how do you care for an epistaxis injury?
- blow nose (to clear clots)
- sit upright with head forward
- cold compress over nose and on back of neck
- after 5 minutes, may need septic or astringent
- after bleeding has stopped, player may return to play --> don't let them blow their nose for 2 hours (may remove clots and cause rebleeding)
74
what is the mindset as a clinician caring for sport-related ocular injuries?
- salvage the remaining vision (once it's gone, it's gone)
- eye injuries have a very high likelihood of being severe
75

82
what is hyphema?
- bleeding within the lens or retina of the eye (not present in the white of the eye)
83
what is the cause of hyphema?

90
what are the 4 steps for a basic eye assessment?
1. history (determine force and direction of force)
2. check vision (before any manipulation)
3. pupil/cornea/conjunctiva
4. eye movements
91
how do you check vision in step 2 of an eye assessment?
- get them to read a chart or newspaper (~ size 12 font)
- diplopia suggests serious injury
92
how do you examine the pupil/cornea/conjunctiva in step 3 of an eye assessment?

97
what is laryngospasm?
- closure of the larynx caused by a spasm (may occur within 4-6 hours)
- causes athlete to panic
98
how do you treat a laryngospasm?
- move the chin forward and place strong anterior pressure behind the angle of the jaw
- hold for 45-60 seconds until you hear inspiration
- the best case scenario, the athlete passes out (this causes them to relax and therefore breathe normally)
99
what are the signs and symptoms of larynx injury (following trauma) --> aka cartilaginous fracture to thyroid/coricoid cartilage (6)
1. speechlessness or hoarse, breathy voice
2. loss of prominence (adams apple)
