Midface - Le Fort I, linear fracture

back to CMF overview

Glossary

General considerations

This is a very rare isolated fracture pattern, mostly occurring in edentulous patients wearing dentures during trauma. More often it occurs in combination with other midface fractures (Le Fort II and Le Fort III).

Observation
Main indication Skill Equipment
Non- or minimally mobile Le Fort I fractures with unaffected occlusion in compliant patients with good dentition. Basic surgical experience, no specialized skills Basic equipment only
Closed treatment
Main indication Skill Equipment
Non- or minimally displaced fractures in a compliant patient amenable to MMF. Basic surgical experience, no specialized skills Basic equipment only

Fractures with minor malocclusion readily correctable with maxillary manipulation, and not grossly mobile after repositioning may be treated closed. However, closed reduction is more commonly used in conjunction with other stabilization techniques (skeletal suspension, external fixators, etc.).

Further indications

  • Premorbid or unstable medical condition preventing general anesthetic
  • Conditions making open reduction and internal fixation difficult
  • Patient refusal of operative treatment (eg, for religious/cultural or financial reasons)
  • Unavailability of plates and screws

Special consideration: MMF may be contraindicated in patients with psychiatric disorders, seizure disorders, and alcoholics.

Open reduction internal fixation
Main indication Skill Equipment
Mobile maxillae with resulting malocclusion in cases where vertical restoration of one or more of the buttresses are indicated. Some specialized surgical experience Simple surgical and imaging resources

Usually, open reduction and internal fixation is the method of choice for mobile maxillae with malocclusion. A minimum of two plates are used to provide stability along the buttresses. Additional plates may support the fragments.
