5 Written questions

5 Matching questions

  1. types of other fractures most often associated with a mandibular condyle fracture
  2. Draw horizontally favorable and unfavorable mandibular angle fractures.
  3. Describe vertically unfavorable mandible fractures.
  4. Treatment of an anterior table frontal sinus fracture involving the frontonasal duct.
  5. Treatement of posterior table frontal sinus fractures.
  1. a Usually involve the body and sympysis-parasymphysis areas.

    The fracture line is posterior on the lateral cortex and anterior on the medial cortex. Therefore, the portion of the mandible posterior to the fracture is pulled medially, displacing the fracture. The mylohyoid is the primary muscle displacing the fracture.
  2. b symphysis and condyle of contralateral side
  3. c 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.
  4. d
  5. e Obliteration vs. close monitoring with CT scans (in reliable patient only).

5 Multiple choice questions

  1. upper 2/3 of facial bones, maxillary sinuses
  2. anterior and medial

  3. zygomas
  4. diploplia and enopthalmos
  5. within 3 hours of injury or from 3-7 days.

5 True/False questions

  1. Long-term complications of orbital blow outenophthalmos, dipoloplia, infraorbital nerve hypesthesia


  2. arterial supply to the mandibleexternal carotid-->internal maxillary-->inferior alveolar


  3. How often do isolated fractures of a single site in the mandible occur?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


  4. Most likely long term outcome from conservative management of orbital blowout fracture (all-comers)?diploplia and enopthalmos


  5. Types of mandible fractures that require treatment with soft diet only (no MMF or ORIF)symphysis and condyle of contralateral side
