  1. TRAUMA Clerk Mary Angeli A. Conti

  2. Treatment Priorities • Maintain airway • Maintain reasonable cardiac output • Evaluation and therapy of any CNS injury • Evaluation and therapy of any abdominal and thoracic injury • Treatment of soft tissue, facial and extremity trauma • Reduction and fixation of facial and extremity fractures

  3. Treatment Priorities • Maintain airway • Evaluate existence & identification of obstruction • Clear of fractured teeth, bood clots, dentures • Endotracheal intubation • Emergency tracheostomy • Last resort • Laryngeal injuries

  4. Treatment Priorities 2. Maintain reasonable cardiac output • Bleeding controlled by direct pressure • IV catheters 3. Evaluate and therapy of CNS injury • Primary concern: C-spine injury • Avoid any movement of spinal column • Immobilization until spinal injuries are ruled out by: Xray, CT scan, neurologic exam

  5. Treatment Priorities 4. Evaluation and therapy of any abdominal and thoracic injury 5. Treatment of soft tissue, facial and extremity trauma 6. Reduction and fixation of facial and extremity fractures

  6. History of traumatic event • Time of injury • Detailed description of the instance surrounding the incident • Seatbelt • Velocities of the vehicle

  7. Diagnosis of Maxillofacial Injuries • Inspection • Palpation • Diagnostic Imaging • Plain films • CT

  8. Physical Examination • Inspection • Consciousness • Soft tissue covering • Facial mobility • All wounds should be probed • Hemorrhage, Otorrhea, Rhinorrhea, Contour deformity, Ecchymosis, Edema, Continuity defects, Malocclusion

  9. Evaluate for laceration • Obvious depression in skull • Asymmetry • Discharge from nose or ear • Assume CSF leak • Palpation to note bone discontinuity

  10. Palpation • Head & neck, locate displaced fractures • Fracture fragments- “Step” defect • Abnormality frontozygomatic sutures CSF Fistula • Nose: Septal mobility • Cheeks • Pain on compression zygoma fracture • Mandible • Neck • Free air  ruptured tracheobronchial tree, crepitations • Tenderness over the larynx fracture

  11. Outline of Discussion Types of Fractures • Nasal • Mandibular • Zygoma & Orbital floor • Maxillary • Frontal Sinus • Definition • Signs & Symptoms • Management

  12. Nasal Fracture • Most common bone injury involving the face • Signs of Nasal Fracture • Depression or displacement of the nasal bone • Edema of the nose • Epistaxis • Fracture of the septal cartilage with displacement or mobility

  13. Nasal Fracture: Management • Always examine for septal hematoma • May progress to abscess formation resorption of cartilage severe saddel-nose deformity • Management • I & D • Placement of temporary drain • Intranasal dressings to compress the septal mucosa • Antibiotic therapy to decrease risk of infection

  14. Nasal Fracture: Management • Repair of Nasal Fracture • Under local anesthesia • After resolution of edema • Reduction techniques (Closed/Open) • Fixation techniques (direct wiring, external suspension, lead plates) • Nasal dressings (internal/ external) • Antibiotic therapy

  15. Mandibular Fracture • 2nd most common fracture of facial skeleton • Most commonly affected: condyle & angle • Signs & symptoms • Malocclusion of the teeth • Tooth mobility • Intraoral lacerations • Pain on mastication • Bone deformity

  16. Mandibular Fracture • Initial evaluation: • Fractures of the teeth • Examine dental occlusion • Intraoral examination

  17. Mandibular Fracture : Management • Immediate treatment: hygiene, antibiotic, analgesics, stabilization, Figure of eight/ Barton’s bandaging • Splinting • Open reduction • Internal wire fixation • Bone plates • Closed reduction • Application of arch bars • Placement into intermaxillary fixation (IMF) • Antibiotics

  18. Zygoma& Orbital Floor Fractures • When untreated, sequelae: • Flattened cheek • Ocular complications (enopthalmos, diplopia) • Zygoma fractures: Signs and symptoms • Palpable deformity in the orbital rim • Diplopia on upward gaze • Hyphesthesia of the cheek • Flattening of the lateral aspect of the cheek • Periorbitalecchymosis • Inferior displacement of the ocular globe

  19. Zygoma Tripod Fractures • Tripod fractures consist of fractures through: • Zygomatic arch • Zygomaticofrontal suture • Inferior orbital rim and floor

  20. Fractures of the orbital floor • Restrited upward gaze • Management • Closed/ Open reduction techniques • Orbital floor reconstruction

  21. Maxillary Fractures • Among the most severe injuries in the face • Signs & Symptoms • Mobility or displacement of the palate • Mobility of the nose in assocition with the palate • Epistaxis • Mobility or displacement of the entire middle third of the face

  22. Maxillary Fractures: Classification LE FORT I • Low transverse fracture involving the palate only • Characterized by: • Displacement of maxillary dental arch & palate • Dental malocclusion • AKA Guerin fracture or 'floating palate‘

  23. LE FORT II • aka Pyramidal fracture • Fracture • en bloc of the palate • Mid 1/3 of the face including the nose • Characterized by: • Mobility of the palate & nose • Epistaxis • Dental malocclusion • Retrodispalecement of palate

  24. LE FORT III • Most severe injury • Complete disruption of the attachment s of the facial skeleton to the cranium • Transverse fracture • Craniofacial dissociation • Dish faced deformity • Predisposes the patient to CSF rhinorrhea more commonly than the other types

  25. Treatment • Open reduction techniques • Firmly fix fractured fragments to intact portions of the skull • Direct wiring , plate stabilization, • Antibiotics

  26. Frontal Sinus Fracture • Maybe extremely serious because of cosmetic deformity & CNS involvement • Signs & Symptoms • Depression of the anterior table of the frontal sinus • Epistaxis • Occasional disruption of the posterior table of the frontal sinus with dural rupture & CSF fluid rinorrhea

  27. Escher classification

  28. Management • Open reduction • Internal fixations • Neurosurgical approach

  29. Indications for surgical treatment of frontobasal fractures

  30. Indications for surgery
