![Page 40: The In’s and Out’s of Pediatric Maxillofacial Trauma](https://reader035.vdocuments.mx/reader035/viewer/2022081603/56815b6b550346895dc9619b/html5/thumbnails/40.jpg)
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
![Page 41: The In’s and Out’s of Pediatric Maxillofacial Trauma](https://reader035.vdocuments.mx/reader035/viewer/2022081603/56815b6b550346895dc9619b/html5/thumbnails/41.jpg)

![Page 42: The In’s and Out’s of Pediatric Maxillofacial Trauma](https://reader035.vdocuments.mx/reader035/viewer/2022081603/56815b6b550346895dc9619b/html5/thumbnails/42.jpg)
Associated Soft-Tissue Injuries

documentation
![Page 43: The In’s and Out’s of Pediatric Maxillofacial Trauma](https://reader035.vdocuments.mx/reader035/viewer/2022081603/56815b6b550346895dc9619b/html5/thumbnails/43.jpg)
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
![Page 44: The In’s and Out’s of Pediatric Maxillofacial Trauma](https://reader035.vdocuments.mx/reader035/viewer/2022081603/56815b6b550346895dc9619b/html5/thumbnails/44.jpg)
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
![Page 45: The In’s and Out’s of Pediatric Maxillofacial Trauma](https://reader035.vdocuments.mx/reader035/viewer/2022081603/56815b6b550346895dc9619b/html5/thumbnails/45.jpg)
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
![Page 46: The In’s and Out’s of Pediatric Maxillofacial Trauma](https://reader035.vdocuments.mx/reader035/viewer/2022081603/56815b6b550346895dc9619b/html5/thumbnails/46.jpg)
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
![Page 47: The In’s and Out’s of Pediatric Maxillofacial Trauma](https://reader035.vdocuments.mx/reader035/viewer/2022081603/56815b6b550346895dc9619b/html5/thumbnails/47.jpg)
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 infectionQuickTime™ and a
decompressorare needed to see this picture.
![Page 48: The In’s and Out’s of Pediatric Maxillofacial Trauma](https://reader035.vdocuments.mx/reader035/viewer/2022081603/56815b6b550346895dc9619b/html5/thumbnails/48.jpg)
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.
![Page 49: The In’s and Out’s of Pediatric Maxillofacial Trauma](https://reader035.vdocuments.mx/reader035/viewer/2022081603/56815b6b550346895dc9619b/html5/thumbnails/49.jpg)
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
![Page 50: The In’s and Out’s of Pediatric Maxillofacial Trauma](https://reader035.vdocuments.mx/reader035/viewer/2022081603/56815b6b550346895dc9619b/html5/thumbnails/50.jpg)
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
![Page 51: The In’s and Out’s of Pediatric Maxillofacial Trauma](https://reader035.vdocuments.mx/reader035/viewer/2022081603/56815b6b550346895dc9619b/html5/thumbnails/51.jpg)
General Management of Maxillofacial Fractures
• Surgical goals of ORIF:– Restoration of occlusion and aesthetic
appearance– Maintain height and width of face– Management of significant bone loss
• Bone grafting

General Management of Maxillofacial Fractures
• Prevent complications – Seizures (depressed skull fractures)– Mucocele – Tear duct obstruction – Enophthalmos – Ectropion– Malocclusion– Retrobulbar hematoma– Corneal abrasion
![Page 53: The In’s and Out’s of Pediatric Maxillofacial Trauma](https://reader035.vdocuments.mx/reader035/viewer/2022081603/56815b6b550346895dc9619b/html5/thumbnails/53.jpg)
Scar Management
• Nonsurgical– Sunscreen– Scar massage– Silicone products– Start 3-4 weeks after wound closure– Facemask in severe cases
![Page 54: The In’s and Out’s of Pediatric Maxillofacial Trauma](https://reader035.vdocuments.mx/reader035/viewer/2022081603/56815b6b550346895dc9619b/html5/thumbnails/54.jpg)
Scar Management
• Surgical- cases not responding to non-operative treatment– Steroid injection– Laser therapy– Dermabrasion– Scar revision– Serial excision– Tissue expansion
![Page 55: The In’s and Out’s of Pediatric Maxillofacial Trauma](https://reader035.vdocuments.mx/reader035/viewer/2022081603/56815b6b550346895dc9619b/html5/thumbnails/55.jpg)
Scar Management
• Scars cannot be removed but most can be improved
• Even “minor” scarring warrants evaluation if only for re-assurance.
• Timing and intervention based on:– Features of scar– Time since injury– Usually minimum of 6 months post-injury
![Page 56: The In’s and Out’s of Pediatric Maxillofacial Trauma](https://reader035.vdocuments.mx/reader035/viewer/2022081603/56815b6b550346895dc9619b/html5/thumbnails/56.jpg)
