Description
Description
- Typically blunt trauma from motor vehicle accidents, sports, direct blows including assaults, or falls
- Gunshot wounds are another common cause
- Consider physical assault and domestic violence, especially in women and children
- Open fractures common
- Many facial fractures are complex and are not easily classified
Etiology
Etiology
- Most common are nasal bone, orbital floor, zygomatic bone, maxillary sinus
- Le Fort fractures involve the maxilla and are classified as:
- Le Fort I: Transverse fracture of maxilla below nose but above teeth through lateral wall of maxillary sinus to lateral pterygoid plate
- Le Fort II: Pyramidal fracture from nasal and ethmoid bones through zygomaticomaxillary suture and maxilla, often involving maxillary sinuses and infraorbital rims
- Le Fort III: Craniofacial disjunction with elongated, flattened face owing to fractures through frontozygomatic suture, orbit, base of nose, and ethmoid bone
- Le Fort IV: Includes frontal bone in addition to Le Fort III
- A patient may have different level Le Fort fractures on each side of the face
- Zygomatic arch fractures often occur in 2 or 3 places and can involve the orbit and maxilla (tripod fracture)
- Inner plate frontal sinus fractures are associated with CSF leaks and ocular injuries
- Orbital fractures most commonly involve the orbital floor (blow-out fracture), and are commonly associated with ocular injuries but can involve the medial and lateral orbital walls
Geriatric Considerations
- Falls most common cause
- Zygoma most common bone fractured (after nasal fractures)
- Beware of associated cervical and intracranial injuries
Pediatric Considerations
- Maxillofacial fractures rarely seen in children <6 yr; suspect nonaccidental trauma
- Falls and motor vehicle accidents account for most cases
- Over 50% have severe associated injuries, high incidence of associated head injury
- Fractures of the orbit are the most common facial fracture in children (excluding nose)
