ENT Flashcards
1
Q
maxillofacial trauma
A
- Often impressive appearance
- ABC’s - airway risk?
- C-spine a priority
- Facial trauma = head trauma
- Vital signs resolving?
- EtOH common
- Other injuries
2
Q
Maxillofacial trauma - history
A
- What happened and when
- Fall? (why fell?), MVA? Assault?
- LOC? Vomiting? Can’t walk?
- Visual symptoms?
- Facial anesthesia/paresthesia?
- Condition of teeth, bite, blown nose?
- Blown nose – they blew their nose and their face puffed up - air now in sinus
- PMH, meds, tetanus
- Police report made?
- Domestic Violence? Child abuse?
3
Q
Maxillofacial trauma - physical exam
A
- Look from above/below/side for asymmetry
- Whistle, smile, wrinkle forehead
- Eyes
- Visual acuity (Rosenbaum card)
- Periorbital - edema, crepitus, lacerations
- EOM’s
- Pupils, conjunctiva and anterior chamber
- Symmetry, subconjunctival hemorrhage, hyphema
- Mouth
- Full, gloved exam
- Lips - lacs, hematoma, thru/thru, vermillion
- Trismus or can’t close?
- Teeth present and intact? Where are they?
- Alveolar ridge, frenulum attachment (put index finger on hard palate and just gently pull to see if there is wiggle)
- Bleeding in mouth?
- Tongue - lacs?
- Nose
- Locate, control bleeding
- Nasoseptal hematoma?
- Palpate medial canthus for mobility
- Ears
- Drainage (blood, CSF?)
- Ear lac?
- Auricular hematoma, Battle sign
- TM’s - hemoptypanum, rupture
- Palpation
- Palpate entire face, both hands
- Look for tenderness, bony crepitus, subcutaneous air, flattening, anesthesia
- Palpate entire orbital rim
- Check if anterior maxillary arch is stable - if it moves at all, stop
- Intraoral palpation of zygomatic arch
- Tongue blade test for mandible Fx- bite down, twist
- If can hold on, likely no Fx
- Tongue blade when you suspect mandible fracture – have them bite down and try to pull the blade out. If you pull it right out and they cant hold it, suspect mandible fracture
4
Q
Managment
A
- ABC’s first - suction
- Consider IV - pain control, Abx; tetanus
- Pain control
- IM/IV or topical (eyes, nose) - avoid po’s
- Imaging - CT preferred over plain film
- Panorex for mandible
- Make a diagnosis before calling a consultant
- Oral Maxillofacial surgeon (OMFS)
- Ophthalmologist
5
Q
Frontal sinus/bone fracture
A
- Significant mechanism
- Step-off, forehead lacs
- High risk for intracrainial injury, dura tear
- Bony crepitus, deformity, subcutaneous air, limited upward gaze, ptosis, sensory deficit forehead
- CT, Abx, OMFS, admit
6
Q
Pediatric considerations
A
- Frontal bone injury more common - check those lacs carefully
- Higher incidence of intracrainial trauma with frontal bone Fx - consider CT head
- Upper cervical spine injury more common than lower in kids
- Non-accidental facial trauma - ?abuse
- Development, cosmetic deformities
7
Q
Nasoethmoidal-orbital fx’s
A
- Small NEO Fx’s easy to miss
- Trauma to bridge, medial orbits
- Associated with lacrimal injury and dural tears
- Pain at medial bridge, w/ EOM’s
- Maybe crepitus, telecanthus
- CT, Abx, OMFS, admit
8
Q
Orbital floor - blow out fx
A
- Orbital floor fx
- Fat, blood into maxillary sinus
- Entrapment of ocular muscles possible (inferior rectus gets stuck)
- Diplopia on upward gaze
- Upward gaze deficit on EOM’s
- 30% have globe rupture
- Management
- CT maxillo-facial and orbits (head?)
- Check eye: vision, hyphema, pressures, subconjunctival hemorrhage, subcutaneous emphysema
- Check infraorbital anesthesia
- OMFS, ophtho consult
- Pain control, tetanus; admit?
- You can have a blow out fracture without entrapment
- Entrapment is when the muscle of the eye is trapped and cant work - you will get double vision when you look up if there is entraptment
9
Q
Retrobulbar hematoma
A
- Collection of blood behind globe
- Trauma, post surgical
- Proptosis, swelling
- CT face/orbits, Ultrasound
- Abx, pain control
- Ophtho consult, admit
- Red Flags: vision loss, pupil irregular, papilledema, IOP up, field deficit = optic neuropathy
- Orbital Compartment Syndrome
- Swelling with optic neuropathy
- Lateral canthotomy to relieve pressure and save vision
10
Q
Periorbital, orbital cellulitis
A
- Unilateral infection around or around (periorbital) and behind (orbital) orbital structures
- Fever, red, swelling
- EOM’s painful
- Proptosis if orbital
- CT orbits all, ULS useful
- Periorbital:
- Abx, +/- admit
- Orbital:
- Serious, vision/life threatening
- Abx (broad spectrum), Ophtho
- consult, admit all
11
Q
nasal fx
A
- Prior nasal trauma, deformity?
- Can you breathe thru your nose?
- Blow nose = face swelling?
- Clinical Dx – minor = no xray
- Suspect NEO Fx or other pathology – CT max/face/orbits
- Check for nasal-septal hematoma
- If present, must I&D or necrosis of septum ensues à
- Document if not present
- “Reduction”- specific cases only
- ENT f/u 5-7 days after edema subsides
12
Q
zygomatic arch
A
- Common; if isolated =less serious
- Direct blow, swelling
- Periorbital edema, subconj hemorrhage, flat cheek bone
- Intraoral exam
- X-rays- “bucket handle” view - depression?
- CT common: other fx’s
- OMFS f/u - cosmesis
13
Q
tripod fracture
A
- Significant mechanism, facial swelling
- Lateral subconjunctival hematoma
- Infraorbital anesthesia
- Check eye, lateral canthus pulled downward
- Trismus
- Consider head injury
- CT for Dx, OMFS consult, Ophtho consult, admit
14
Q
maxilla fractures
A
- High-energy, midface, not subtle
- LeFort Fx’s
- Fracture patterns often mixed
- Check hard palate/upper teeth mobility
- CT, Abx, tetanus
- OMFS and Optho consult
- Admit for open reduction and fixation
- Persistent nose bleed common
- Intracranial injury common – CT head too
15
Q
mandible anatomy and mandible fxs
A
- Open or closed?
- Multiple fx’s common
- Tender, swelling, trismus, malocclusion, jaw ecchymosis, bite test
- Sublingual hematoma is pathognomonic
- Panorex; then/or CT
- Open = blood in mouth, gingival lacs, teeth loose separated or uneven
- Open - OMFS, Abx, tetanus, admit
- Closed - outpatient f/u
16
Q
TMJ dislocation
A
- Jaw stuck open - post trauma, seizure or spontaneous
- Hx of same?
- Unilateral - jaw away from side of dislocation. Bilateral - protrudes forward
- X-rays if traumatic
- Pain meds, anxiolytics, suction
- Reduction: Downward pressure, rock and pull forward - from above or from front of patient
- Liquid diet for 3 days, OMFS f/u
17
Q
hearing loss
A
- Sudden or gradual?
- Partial or total?
- Unilateral or bilateral?
- Trauma, recent infection, meds (bilateral)
- NSAIDS, aminoglycosides, erythromycin, Lasix, ASA, antimalarials, chemo
- Associated Sx’s: tinnitus, vertigo, HA, drainage, pain
- Conductive or Sensorineural?
- Look in ear first, then look for the tuning fork
- Conductive loss is common
- Cerumen (most common), TM perf, OE, SOM, FB
- Weber test - tuning fork on head
- Conductive - heard best in affected ear
- Sensorineural - heard best in good ear
- Rinne test - mastoid then next to ear
- Conductive - BC>AC
- Sensorineural loss - AC>BC or can’t hear it
