  1. The In’s and Out’s of Pediatric Maxillofacial Trauma Wellington J. Davis III, MD, FACS Section of Plastic and Reconstructive Surgery St. Christopher’s Hospital for Children Philadelphia, PA

  2. Introduction • Maxillofacial trauma evaluation • Key problems and Work-Up • Classification of fractures and associated clinical problems • General management • Scar management

  3. Initial Survey • Control airway and breathing • Control bleeding • Resuscitation • Head injury-GCS? • R/O C-spine injury • Associated with 10% of maxillofacial injuries

  4. Initial Survey • Control airway • In-line stabilization • Oral intubation possible in almost all cases • Rarely tracheostomy needed • Check for aspiration teeth/blood

  5. Initial Survey • Airway Issues • May revisit airway for surgery • Nasotracheal intubation • Tracheostomy • Wire cutters to bedside

  6. Initial Survey • Control bleeding • Address the scalp • Whip-stitch vs. staples • Pressure dressing • Nasal packing • Foley catheters • Fracture reduction • Arch bars • Angiography and embolization

  7. Initial Survey • Resuscitate • Hb/Hct • 2 large bore IV’s • Neurologic status • GCS? • C-spine injury

  8. Secondary Survey • Systematic evaluation for: • Lacerations • Palpate for bony step-off at bony prominences • Mid-facial stability • Check sensation in trigeminal distribution • Check facial nerve function

  9. Secondary Survey • Systemic Evaluation for: • Dentition • Occlusion • Ophthalmologic injury/vision • Recheck for C-spine injury • CSF leak

  10. Secondary Survey • Check for lacerations • Scalp • Retroauricular • No real contraindication to closure based on time of injury • Absorbable sutures acceptable and preferable

  11. Secondary Survey • Palpate step-offs • No step-off, CT scan may not be indicated • Bimanual maxillary exam • Critical to document sensation and vision prior to surgery • Facial nerve evaluation • Raise brows • Eye closure • Puff cheeks • Smile

  12. Secondary Survey • Look in the mouth • Empty sockets? • Chipped teeth? • Chest x-ray check for teeth • Check the bite • Patient can detect a poppy seed b/w teeth • Occlusion test very sensitive for mandibular or maxillary fractures

  13. Secondary Survey • Ophthalmology evaluation • All orbital fractures especially in operative cases • Check for entrapment • Limited EOM • Generally painful • Emergent • Hyphema emergency • Retinal tears • Corneal abrasions

  14. Secondary Survey • Re-check the neck • CSF leak, dural tear • Beta-transferrin

  15. Work-Up • Labs • CBC • Type and Cross • Imaging • CT scan with thin cuts • Axial • Coronal, • Sagittal views • Panorex

  16. Work-Up • Consultations • Maxillofacial surgeon • Plastics • ENT • OMFS • Dental • Ophthalmology • Neurosurgery

  17. Types of Fractures • Frontal sinus (anterior, posterior) • Naso-orbital-ethmoid • Orbit • Nasal fractures • Maxilla and zygoma • ZMC • Lefort fracture • Mandibular • Condyle, coronoid, ramus, body, symphysis

  18. Types of Fractures • Frontal Sinus Fractures • CSF leak • Dural Tear • Aesthetic deformity • Mucocele • Nasofrontal duct obstruction • Intervention: Immediate to 7 days

  19. Types of Fractures • Naso-orbital-ethmoid • Saddle nose deformity • Telecanthus • Widening of medial canthi • Enophthalmos • Intervention: Immediate to 7 days

  26. Post-op

  27. Medial Wall Fracture With Entrapment

  28. Imaging

  29. Types of Fractures • Maxillary and zygomatic fractures • Occlusion problems • Facial lengthening or widening • Contour deformity • Intervention: 5-7 days

  31. 3D CT scan

  32. Intra-op

  33. Intra-op

  34. Types of Fractures • Nasal Fractures • Aesthetic deformity • Airway obstruction • Isolated nasal fracture clinical diagnosis • Imaging not mandatory • Intervention: 5-7 days

  35. Types of Fractures • Mandible fractures • Occlusion problems • Aesthetic deformity • Antibiotics needed, considered an open fracture in mouth • Generally warrant aggressive surgical management • Intervention: 2-5 days

  36. Associated Soft-Tissue Injuries • Extensive lacerations eyelid, eyebrow, nose, lip, ear • Mucosal and tongue lacerations • Alveolar ridge fractures • Tear duct injuries • Stenson’s duct injury • Globe injuries • Hyphema • Retinal tears

  37. Associated Soft-Tissue Injuries • Facial nerve injury • Infraorbital nerve injury • Inferior alveolar nerve injury • Mental nerve injury • Supraorbital nerve injury • Sensory nerve function important for documentation

  38. General Management of Maxillofacial Fractures • Management Based On: • Type of fracture • Location of fracture • Amount of displacement • Timing of injury • Age of patient (Mandible) • Surgical approach based on surgeon experience, principles the same

  39. General Management of Maxillofacial Fractures • Only 15-20% of maxillofacial fractures are operative • Non-displaced fractures • Consider outpatient management with early follow-up 24-48 hours with maxillofacial specialist • No surgery in almost all cases except mandible • Mandible may require arch bars and wiring based on location of fracture

  40. General Management of Maxillofacial Fractures • Unstable patients • Arch bars minimum in maxillary or mandibular fractures • If poor GCS but hemodynamically stable best to repair most severe fractures in the usual time frame 5-7 days • Why? • Major functional problems if patient survives • Occlusion • Visual • Aesthetics • Difficult to repair secondarily

  41. General Management of Maxillofacial Fractures • Displaced fractures • ORIF • Bone grafts in complex cases • Complex cases may benefit from tracheostomy pre-op • Resorbable plates preferred in pediatric patients • Potential for growth restriction

  42. General Management of Maxillofacial Fractures • Timing • Ideally within 5-7 days before bony healing • Isolated orbital fracture could wait longer • Most surgeons prefer for edema to resolve prior to surgery • Mandible fracture tend to be done early w/i 24-48 hours to decrease risk of infection

  43. General Management of Maxillofacial Fractures • Unrepaired fractures may require osteotomies for correction especially if addressed 3 or more weeks after injury. • Surgery is much more complex and accurate reduction more difficult.

  44. General Management of Maxillofacial Fractures • Minimal scarring due to craniofacial approaches: • Bicoronal incision • Transconjunctival/Subciliary/Orbital rim • Brow or upper lid incisions • Buccal sulcus incisions • Preauricular • Risdon incision • Gilles approach • Existing lacerations

  45. General Management of Maxillofacial Fractures • 2-5 hour cases depending on complexity • Generally minimal blood loss • Sometimes multiple teams • Post-op management overnight stay • Monitoring for retrobulbar hematoma in orbital cases
