Facial Fractures Flashcards
What is a LeForte Fracture?
A fracture of the Maxillary bone
What is the usual mechanism of injury involved in a LeForte Fracture?
High velocity blunt force
- Altercations
- Falls
- Car accidents
How many types of LeForte Fractures are there?
Three (different fracture pattern, same technique to fix)
- LeForte I
- LeForte II
- LeForte III
Describe: LeForte Fracture I
Fracture of the Upper Jaw
-From Nasal Septum to Pterygomaxillary Junction
Fracture travels horizontally above the teeth apices
What are the steps for surgical repair of a LeForte Fracture I?
- Disimpaction of the fracture
- Maxillary-mandible fixation (wiring jaw shut)
- Miniplates and screws
What type of incision is made for a LeForte Fracture I?
Gingivolabial incision (where gum and upper lip meet)
Describe: LeForte Fracture II
Fracture of the upper jaw and nose
-Pyramidal fracture from Nasal Bridge through Lacrimal Bones to the Pterygoid Plates
What are the types of incisions that are used to repair a LeForte Fracture II?
- Transconjunctival incision
- Subciliary incision
- Gingivolabial incision
What are the steps for surgical repair of a LeForte Fracture II?
- Disimpaction of the fracture
- Maxillary-mandible fixation (wiring jaw shut)
- Miniplates and screws
Describe: LeForte Fracture III
Fracture extending from Nasofrontal and Frontomaxillary Suture to the base of the Sphenoid
-Extends through Orbital Bone and Zygomatic Arch
What are the types of incisions that are used to repair a LeForte Fracture III?
- Labellar fold incision
- Gingivolabial incision
- Subciliary incision
- Transconjunctival incision
- Lateral brow incision
- Bicoronal incision
What are the steps for surgical repair of a LeForte Fracture III?
- Disimpaction of the fracture
- Maxillary-mandible fixation (wiring jaw shut)
- Miniplates and screws
