upper 2/3 of facial bones, maxillary sinuses
- b Obliteration vs. close monitoring with CT scans (in reliable patient only).
- c enophthalmos, dipoloplia, infraorbital nerve hypesthesia
- d 1. isolated nondisplaced fractures of the coronoid
2. unilateral nondisplaced subcondylar fracture with normal occlusion
- e rapid rewarming in circulating water. avoid rubbing and dry heat as both of these predispose to liquefactive necrosis. surgical debridement not indicated for 3 weeks for final demarcation of injury

- An imaginary line drawn at the canines
- external carotid-->internal maxillary-->inferior alveolar
- If no displacement or e/o CFS leak, observe and give abx. If displaced, obliteration and possible repair of dural tear. Cranialization reserved for fracture with significant bone loss or comminution.
5 True/False questions
How often do isolated fractures of a single site in the mandible occur? → 6%
What are class II and III occlusion? → external carotid-->internal maxillary-->inferior alveolar
what are the most common complications of orbital floor repair → diploplia and enopthalmos
Most likely long term outcome from conservative management of orbital blowout fracture (all-comers)? → Cheek hypesthesia. Enopthalmos likely if >50% of floor.
When do fibrillation potentials appear in Wallerian degeneration? → Associated fibrillation potentials show up starting 3 days after injury.
