    Study Notes

    Maxillofacial Trauma

    Why Advance?

    • We are in a hospital setting, where basic life support is crucial in case of trauma, especially maxillofacial trauma.

    Horizontal Buttresses

    • Serve as cross-member stability to the facial skeleton
    • Define the antero-posterior and horizontal dimensions of the face
    • Types of horizontal buttresses:
      • Frontal bar (most superior horizontal buttress)
      • Upper transverse maxillary buttress (most important horizontal buttress)
      • Lower transverse maxillary buttress
      • Transverse mandibular buttress

    Imaging and Diagnosis

    • Imaging studies can help diagnose maxillofacial trauma
    • CT scans can show fractures in the facial bones and mandible
    • X-rays can show fractures in the mandible

    Classification of Mandibular Fracture

    • Simple: mucosa and skin intact
    • Compound or open: exposure of bone intraorally
    • Greenstick: incomplete, only one cortical surface
    • Comminuted: several small fragments of bone
    • Complex: with fractures of other areas of mandible
    • Complicated: involves both mandible and maxilla

    History and Physical Examination

    • Evaluate patients from head-to-toe
    • Ask specific questions to gather data about the patient's injuries
    • Important to assess the patient's neurological status using the Glasgow Coma Scale (GCS)
    • Evaluate the patient's airway, breathing, and circulation (ABCs)
    • Ask about the patient's last meal and drink, and when they were consumed
