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
