The document discusses fractures of the maxilla and midface. It notes that maxilla fractures can be life-threatening and disfiguring if not treated properly. The maxilla acts as a bridge between the cranial base and dentition. Midface fractures are now more complex than those produced in le Fort's laboratory, and a more precise system is needed to describe fracture patterns to aid in diagnosis and determining surgical approaches. Current management of le Fort fractures involves stabilizing the upper midface to the frontal skeleton and lower midface to the mandibular skeleton.

2. The maxilla
represents a bridge
between the cranial
base superiorly and
dentition inferiorly.

3.  Fractures of these bones is potentially life
threatening and also disfiguring.
 Systemic and timely repair of these fractures
is important to correct deformity and prevent
unfavorable sequelae

5. Heads were subjected to low velocity forces ,soft tissues were then
removed and fracture lines examined on 32 cadavers.

6.  Lacrimal fossa is partly formed by maxilla
hence fracture can cause injury to
nasolacrimal duct

9.  CHANGE IN OCCULAR LEVEL DUE TO
SEPARATION ABOVE THE ATTACHMENT
OF SUSPENSARY LIGAMENT OF
LOCKWOOD.

10.  Herniation of orbital floor. Characteristic tear
drop!

27.  Midface fractures are now far more complex
than those produced in le forts’laboratory.

29. Fractures involving cranial base and other
midface configurations including severely
comminuted segments are not accurately
classifiable using the traditional Le fort
scheme.
 A more precise system of describing fracture
pattern is necessary to establish accurate
diagnosis and determine potential surgical
approaches.

31.  Current management of lefort fractures
include stabilization of upper midface to
frontal skeleton.lower midface is stabilized to
mandibular skeleton.
 Evaluation of pattern of fractural fragments
keeping structural pillars in mind.
 Management should be considered in terms
of functional units and horizontal and vertical
buttresses.
