CAISS Face Injuries 1 — Questions and Answers
Question 1: In the AIS coding system, which anatomical structures are primarily covered in the face chapter?
- Skull and brain tissue
- Nose, orbits, jaw, and facial soft tissue (Correct answer)
- Cervical vertebrae and spinal cord
- External ear and mastoid process
Correct answer: Nose, orbits, jaw, and facial soft tissue
The face chapter in AIS covers facial structures including the nose, orbits, mandible/maxilla, zygomatic bones, and facial soft tissue.
Question 2: Which of the following fractures would be coded in the face chapter of the AIS?
- Temporal bone fracture
- Occipital bone fracture
- Mandibular fracture (Correct answer)
- Parietal bone fracture
Correct answer: Mandibular fracture
Mandibular fractures are coded in the face chapter because the mandible is part of the facial skeleton, not the cranium.
Question 3: What AIS severity score is typically assigned to a simple, non-displaced nasal bone fracture?
- AIS 1 (Correct answer)
- AIS 2
- AIS 3
- AIS 4
Correct answer: AIS 1
Simple non-displaced nasal bone fractures are minor injuries posing no life threat and are coded AIS 1.
Question 4: In AIS coding, orbital fractures are classified under which body region chapter?
- Head
- Neck
- Face (Correct answer)
- External
Correct answer: Face
Orbital fractures are classified in the face chapter because the orbits are part of the facial skeleton surrounding the eyes.
Question 5: Which description best defines a Le Fort II fracture for AIS coding purposes?
- A palatal fracture separating palate from maxilla
- A pyramidal fracture through maxilla, nasal bones, and orbital floors (Correct answer)
- A transverse fracture at the nasal floor level
- A complete craniofacial separation at the skull base
Correct answer: A pyramidal fracture through maxilla, nasal bones, and orbital floors
Le Fort II is a pyramidal fracture involving the maxilla, nasal bones, and orbital floors, representing a moderate-to-severe facial injury pattern.
Question 6: How are isolated facial lacerations requiring sutures but with no underlying structural damage coded in AIS?
- They are not coded in AIS
- AIS 1 for minor soft tissue injuries (Correct answer)
- AIS 2 for any laceration requiring sutures
- AIS 3 for all facial lacerations
Correct answer: AIS 1 for minor soft tissue injuries
Facial lacerations requiring sutures without underlying structural damage are typically coded AIS 1, reflecting a minor injury.
Question 7: Among isolated facial injuries, which would typically receive the highest AIS severity score?
- Simple nasal bone fracture
- Mandibular fracture, minimally displaced
- Panfacial fractures involving multiple facial regions (Correct answer)
- Isolated orbital floor fracture
Correct answer: Panfacial fractures involving multiple facial regions
Panfacial fractures involve multiple facial bones across several facial regions and receive higher AIS scores reflecting their complexity and extent.
