Study Notes

Nasal Fractures

  • Relatively little force is required to fracture the nasal bones
  • Most fractures result from laterally applied forces (over 66%)
  • Fractures following frontal injuries accounted for 13%
  • Greater force is required to fracture the nose with a blow directed from the front as the nasal cartilages behave like shock absorbers

Causes

  • Trauma including accidental personal assaults, sports injury and RTA (road traffic accident)
  • Domestic violence
  • Falls (common in children)
  • Falls from syncope or impaired balance in the elderly

Nasal Fracture Classification

  • Class 1: Frontal or frontolateral trauma, vertical septal fracture, depressed or displaced distal part of nasal bones
  • Class 2: Lateral trauma, horizontal or C-shaped septal fracture, bony or cartilaginous septum fracture, frontal process of maxilla fracture
  • Class 3: High velocity trauma, fracture extends to ethmoid labyrinth, bony septum rotates posteriorly, bridge collapse, upturned tip revealing nostrils, depressed nasal bones pushed up under frontal bones, apparent inter-ocular space widening (telecanthanus)

Clinical Presentation

  • History: A detailed history should include the following:
    • Mechanism of trauma: What was the direction of the force and the nature of the striking object? Was there associated epistaxis at the time of the trauma? Stops spontaneously
    • History of previous facial trauma or surgery
    • Other than swelling, is the nasal appearance different from before the trauma?
    • Does the patient perceive a functional impairment in breathing compared to before the trauma? If so, which nostril is impaired?
    • Is the nasal fracture related to an assault or motor vehicle accident?

Nasal Fractures

  • Relatively low force is required to fracture nasal bones, lateral forces most common
  • Most fractures result from laterally applied forces (over 66%), followed by frontal injuries (13%)
  • Nasal cartilages can absorb shock, requiring higher force for a fracture to occur from the front
  • Fractures are often a result of trauma including personal assaults, sports injuries and road traffic accidents, domestic violence, falls, syncope (common in the elderly)

Nasal Fracture Classification

  • Class 1: Frontal or frontolateral trauma, vertical septal fracture, depressed or displaced distal part of nasal bones
  • Class 2: Lateral trauma, horizontal or C-shaped septal fracture, bony or cartilaginous septum fracture, frontal process of maxilla fracture
  • Class 3: High velocity trauma, fracture extends to ethmoid labyrinth, bony septum rotates posteriorly, bridge collapse, upturned tip revealing nostrils, depressed nasal bones pushed up under frontal bones, apparent inter-ocular space widening (telecanthanus)

Clinical Presentation

  • A detailed history should include the following:
    • Mechanism of trauma: Direction of force, nature of striking object.
    • Episaxis: Occurred at the time of trauma and whether it stopped spontaneously.
    • History of prior facial trauma or surgery.
    • Changes in nasal appearance since the trauma.
    • Functional impairment in breathing compared to pre-trauma.
    • If there's impairment, which nostril is affected.
    • Relation of nasal fracture to assault or motor vehicle accident.

Septal Hematoma

  • A collection of blood under the nasal septum's mucoperichondrium.
  • Can follow nasal trauma, sometimes occurring as a complication of septal surgery rarely.
  • It can also be caused by blood dyscrasias
  • Clinical presentation is complete bilateral nasal obstruction
  • Complications:
    • Septal abscess
    • Cartilage necrosis
    • Nasal saddle deformity
  • Treatment:
    • Aspiration if the hematoma is small.
    • Incision and drainage with quilt suturing.
    • Antibiotics to minimize risk of local and systemic infection.

Nasal Fractures

  • Relatively little force is required for nasal bone fracture
  • Most fractures caused by lateral force
  • Fractures following frontal injuries account for 13% of cases
  • Cartilage in nose behaves like shock absorber,
  • Requires more force to fracture when hit from the front
  • Falls, assaults, sports injuries, and RTA are common causes

Classification of Nasal Fractures

  • Class 1:
    • Frontal or frontolateral trauma
    • Vertical septal fracture,
    • Distal part of nasal bones depressed or displaced
  • Class 2:
    • Lateral trauma,
    • Horizontal or C-shaped septal fracture,
    • Bony or cartilaginous septum fracture,
    • Frontal process of maxilla fracture
  • Class 3:
    • High-velocity trauma,
    • Fracture extends to ethmoid labyrinth,
    • Bony septum rotates posteriorly,
    • Bridge collapse,
    • Upturned tip with revealing nostrils,
    • Depressed nasal bones pushed up,
    • Apparent inter-ocular space widening (telecanthanus)

Clinical Presentation

  • Take detailed history
  • Mechanism of trauma: Direction of force, nature of object causing trauma, presence of epistaxis,
  • Previous facial trauma or surgery
  • Physical appearance compared to pre-trauma
  • Functional impairment in breathing
  • If functional impairment exists: Which nostril is impaired?
  • Is the nasal fracture related to assault or motor vehicle accident?
