    Study Notes

    Facial Fractures

    Classification

    • Le Fort Fractures: involve the midface, classified into 3 types:
      • Le Fort I: horizontal fracture above the teeth, involving the maxilla and palate
      • Le Fort II: pyramid-shaped fracture, involving the maxilla, zygoma, and lacrimal bone
      • Le Fort III: involves the entire midface, including the zygoma, lacrimal bone, and cribiform plate
    • Mandibular Fractures: involve the lower jaw, classified into 3 types:
      • Symphysis fracture: involves the midline of the chin
      • Body fracture: involves the horizontal ramus or angle of the jaw
      • Condylar fracture: involves the temporomandibular joint
    • Zygomatic Fractures: involve the cheekbone, classified into 3 types:
      • Zygomatic arch fracture: involves the arch of the cheekbone
      • Zygomaticomaxillary fracture: involves the cheekbone and maxilla
      • Tripod fracture: involves the zygoma, maxilla, and orbit

    Causes

    • Blunt Trauma: most common cause of facial fractures, resulting from:
      • Motor vehicle accidents
      • Falls
      • Assaults
      • Sports injuries
    • Penetrating Trauma: less common cause, resulting from:
      • Gunshot wounds
      • Stab wounds
      • Other penetrating injuries

    Symptoms

    • Pain and Swelling: common symptoms of facial fractures
    • Facial Deformity: may be present, depending on the type and severity of the fracture
    • Dental Malocclusion: teeth may not fit together properly due to fracture displacement
    • Eye Symptoms: may include vision changes, double vision, or eye movement limitation

    Diagnosis

    • Clinical Examination: visual inspection, palpation, and range of motion tests
    • Imaging Studies: radiographs (e.g., Panorex, CT scans) to confirm diagnosis and assess extent of injury
    • Dental Evaluation: dental examination to assess dental occlusion and potential tooth involvement

    Classification of Facial Fractures

    • Le Fort Fractures involve the midface and are classified into 3 types: Le Fort I, Le Fort II, and Le Fort III.
    • Le Fort I involves a horizontal fracture above the teeth, affecting the maxilla and palate.
    • Le Fort II involves a pyramid-shaped fracture, affecting the maxilla, zygoma, and lacrimal bone.
    • Le Fort III involves the entire midface, including the zygoma, lacrimal bone, and cribiform plate.

    Mandibular Fractures

    • Mandibular Fractures involve the lower jaw and are classified into 3 types: Symphysis fracture, Body fracture, and Condylar fracture.
    • Symphysis fracture involves the midline of the chin.
    • Body fracture involves the horizontal ramus or angle of the jaw.
    • Condylar fracture involves the temporomandibular joint.

    Zygomatic Fractures

    • Zygomatic Fractures involve the cheekbone and are classified into 3 types: Zygomatic arch fracture, Zygomaticomaxillary fracture, and Tripod fracture.
    • Zygomatic arch fracture involves the arch of the cheekbone.
    • Zygomaticomaxillary fracture involves the cheekbone and maxilla.
    • Tripod fracture involves the zygoma, maxilla, and orbit.

    Causes of Facial Fractures

    • Blunt Trauma is the most common cause of facial fractures, resulting from motor vehicle accidents, falls, assaults, and sports injuries.
    • Penetrating Trauma is a less common cause, resulting from gunshot wounds, stab wounds, and other penetrating injuries.

    Symptoms of Facial Fractures

    • Pain and Swelling are common symptoms of facial fractures.
    • Facial Deformity may be present, depending on the type and severity of the fracture.
    • Dental Malocclusion may occur, with teeth not fitting together properly due to fracture displacement.
    • Eye Symptoms may include vision changes, double vision, or eye movement limitation.

    Diagnosis of Facial Fractures

    • Clinical Examination involves visual inspection, palpation, and range of motion tests.
    • Imaging Studies, such as radiographs (e.g., Panorex, CT scans), are used to confirm diagnosis and assess extent of injury.
    • Dental Evaluation involves a dental examination to assess dental occlusion and potential tooth involvement.
