Face Injuries Flashcards

In the AIS coding system, which anatomical structures are primarily covered in the face chapter?

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.

Which of the following fractures would be coded in the face chapter of the AIS?

Answer: Mandibular fracture

Mandibular fractures are coded in the face chapter because the mandible is part of the facial skeleton, not the cranium.

What AIS severity score is typically assigned to a simple, non-displaced nasal bone fracture?

Answer: AIS 1

Simple non-displaced nasal bone fractures are minor injuries posing no life threat and are coded AIS 1.

In AIS coding, orbital fractures are classified under which body region chapter?

Answer: Face

Orbital fractures are classified in the face chapter because the orbits are part of the facial skeleton surrounding the eyes.

Which description best defines a Le Fort II fracture for AIS coding purposes?

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.

How are isolated facial lacerations requiring sutures but with no underlying structural damage coded in AIS?

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.

Among isolated facial injuries, which would typically receive the highest AIS severity score?

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.

Which structure, when fractured, would be coded in the face chapter rather than the head chapter of AIS?

Answer: Zygomatic arch

The zygomatic arch is part of the facial skeleton; fractures here are coded in the face chapter, not the head chapter.

A patient presents with 4 avulsed teeth after a motor vehicle collision. How should this be coded in AIS?

Answer: All avulsed teeth are captured with a single face chapter code

Multiple avulsed teeth are captured with a single AIS code from the face chapter rather than coding each tooth individually.

When coding facial soft tissue injuries in AIS, which factor most directly determines the severity score?

Answer: Depth and extent of the injury

The depth and extent of facial soft tissue injury — whether it is an abrasion, laceration, or avulsion — are the primary determinants of AIS severity.

In AIS, traumatic enucleation of the eye is classified under which chapter?

Answer: Face chapter

Eye injuries including traumatic enucleation are coded in the face chapter because the eye is housed within the orbit, a facial structure.

A patient with a mandibular fracture undergoes open reduction and internal fixation (ORIF). What AIS score would this injury most likely receive?

Answer: AIS 2

Mandibular fractures requiring ORIF are typically coded AIS 2, indicating a moderate injury with significant treatment needs but no immediate life threat.

Which of the following is NOT typically included in the face chapter of the AIS?

Answer: Cervical vertebrae fractures

Cervical vertebrae fractures are coded in the spine chapter; they involve the neck's spinal column rather than facial structures.

When coding a Le Fort III fracture (craniofacial disjunction) in AIS, what severity score is typically assigned?

Answer: AIS 3

Le Fort III fractures represent complete craniofacial separation and are coded AIS 3, reflecting a serious injury that is life-threatening without intervention.

What does the term 'panfacial fracture' signify for AIS coding purposes?

Answer: Fractures involving multiple facial bones across different facial regions

Panfacial fractures involve multiple facial bones spanning several regions of the face and receive higher AIS scores reflecting their anatomical complexity.

How should a coder classify a facial contusion with hematoma in AIS?

Answer: AIS 1 for minor soft tissue injury in the face chapter

Facial contusions with hematoma are minor soft tissue injuries coded AIS 1 in the face chapter, as they pose minimal life threat.

In AIS, orbital blowout fractures are primarily classified based on which factor?

Answer: The specific orbital wall(s) involved and fracture severity

Orbital blowout fractures are classified in AIS by which orbital walls are fractured and the complexity of the fracture pattern, not patient factors.

A trauma patient has both a frontal sinus fracture and a basilar skull fracture. How should these injuries be coded?

Answer: Code each separately: frontal sinus in face chapter, basilar skull in head chapter

Each injury is coded separately in its appropriate AIS chapter — frontal sinus in the face chapter and basilar skull fracture in the head chapter — to fully capture all injuries.

What is the typical maximum AIS severity score assigned to isolated facial injuries?

Answer: AIS 3

Isolated facial injuries typically max out at AIS 3; facial injuries rarely reach AIS 4 or 5 because the face is not directly vital to immediate survival on its own.

Where are traumatic bilateral facial nerve injuries coded in the AIS?

Answer: Face chapter, as facial nerve injuries involve facial structures

Facial nerve injuries are coded in the face chapter of the AIS because the facial nerve primarily serves facial motor and sensory function in the facial region.
