4. INTRODUCTION:
The maxilla represents the bridge between the cranial base
superiorly and the dentition inferiorly. Its intimate association
with the oral cavity, nasal cavity, and orbits and the important
structures adjacent to it make the maxilla a functionally and
cosmetically important structure.

5. Fracture of these bones is potentially life-threatening as
well as disfiguring. Hence we being maxillofacial
surgeons need to do systematic and timely repair of
these fractures to correct deformity and prevent
unfavorable sequalae.

6. HISTORY
• The first clinical examination of a maxillary fracture was
recorded in 2500 BC.
• In 1822 Charles Fredrick William Reiche provided the
first detailed description of maxillary fractures.
• In 1823 Carl Ferdinand van Graefe described the use of a
head frame for treating a maxillary fracture.

7. • In 1901 , Rene Le Fort published his landmark work, a
three-part experiment using 32 cadavers.
• The heads of the cadavers were subjected to low velocity
forces; the soft tissue were then removed and the bones
were examined.
HISTORY

8. • Le Fort noted that generally face was fractured and the
skull was not. He then stated that fractures occurred
through three weak lines in the facial bony structure. From
these three lines the Le Fort classification system was
developed.
HISTORY

9. External Fixation
Craniomaxillary fixation- Wassmund’s(1927) maxillary splint
with side bars attached to a head cap

10. SURGICAL ANATOMY OF MIDFACE
• Lacrimal fossa is partially formed by maxilla .Hence
fracture can cause injury to nasolacrimal duct.
• Damage to infraorbital nerve can occur unilaterally or
bilaterally in fracture of maxilla.
• Fracture involving orbital walls may give rise the
change in the ocular level due to separation above the
attachment of suspensory ligament of lockwood.
(LeFort III)
• If orbital floor is fractured, there will be herniation of
orbital content into maxillary sinus.

11. ETIOLOGY -
• Road traffic accidents (most common) -40%
• Industrial accidents- 10 %
• Assault -15%
• Sports.- 25 %
• Fall.- 10 %

12. • Most maxillary fractures occur in young men aged
between 16 to 40 years.
• Peak age- 21 - 25 years
• Male : Female - 4:1

13. Lefort fracture classification
Rene LeFort (1901) discovered the complex
fracture patterns of Maxilla which is broadly
classified as
1. Lefort I
2. Lefort II
3. Lefort III

14. IMPORTANT POINTS TO REMEMBER
(i) These fractures may occur unilaterally or may be
associated independently with a fracture of the zygomatic
complex.
(ii) There may be a midline separation of the maxillae or
extension of the fracture pattern into the frontal or
temporal bones.

15. LIMITATIONS OF THE lefort CLASSIFICATION
• The LeFort classification has proven to be less satisfactory
to describe more complex fracture patterns, comminuted,
incomplete, combination maxillary fractures or to describe
fractures of the part bearing the occlusal segment.

16. • Need for newer system:
• Midface fracture patterns now are far more complex than those
produced in Le Fort's laboratory.
• Fractures involving the cranial base and other midface fracture
configurations, including severely comminuted segments of the
facial skeleton, are not accurately classifiable using the traditional
Le Fort scheme.
• A more precise system of describing fracture patterns is necessary
to establish an accurate diagnosis & determine potential surgical
approaches.

17. • MODIFIED LEFORT CLASSIFICATION:
Proposed by Marciani (1993)
• Le Fort I Low maxillary fracture
Ia Low maxillary fracture/multiple segments
• Le Fort II Pyramidal fracture
IIa Pyramidal and nasal fracture
IIb Pyramidal and NOE fracture
• Le Fort III Craniofacial disjunction
IIIa Craniofacial disjunction and nasal fracture
IIIb Craniofacial disjunction and NOE fracture.
(From: Marciani RD. Management of Midface Fractures: fifty years later. J Oral Maxillofac Surg 1993;51:962.)

18. • Le Fort IV LeFort II or III fracture and
cranial base fracture
IV a + Supraorbital rim fracture
IV b + Anterior cranial fossa and
supraorbital rim fracture
IV c + Anterior cranial fossa and
orbital wall fracture

19. • There is separation of complete
dentoalveolar part of maxilla
(Pterygomaxillary dysjunction) and
the fractured fragment is held only by
means of soft tissues.
• Cause -
A violent force applied over more
extensive area of maxilla above the
level of maxillary teeth results in
Lefort I fracture.

20. Fracture line –
The fracture line commences at
the point on the lateral margin
of the anterior nasal aperture,
passes above the nasal floor,
passes laterally above the canine
fossa and traverses the lateral
antral wall, dips down below the
zygomatic buttress and then
inclines upward and posteriorly
across the pterygomaxillary
fissure to fracture the pterygoid
laminae at the junction of their
lower third and upper 2/3 rd.

21. LE FORT II
Cause –
Violent force, usually from an
anterior direction, sustained
by the central region of the
middle third of the facial
skeleton over an area
extending from glabella to
the alveolar margins results
in fracture of pyramidal
shape .

22. Fracture line -
The fracture line runs below
frontonasal suture from the
thin middle area of nasal
bones down on either side
crossing the frontal process
of maxilla and passes
anteriorly across the lacrimal
bone, immediately anterior to
nasolacrimal canal. Then
fracture line passes
downward, forward and
laterally crossing the inferior
orbital margin in the region
of zygomaticomaxillary
suture

23. • . It may or may not involve
infraorbital foramen. Then
fracture line now extends
downward, forward and
laterally to traverse the
lateral wall of antrum, just
medial
zygomaticomaxillary
suture line.

24. As in Lefort I , this fracture line
passes beneath the Zygomatic
buttress, inclines abruptly traversing
the pterygomaxillary fissure at a
higher level and fracturing
the pterygoid laminae approximately
midway from its base. Seperation of
entire pyramidal block from the base
of the skull is completed via nasal
Septum.

25. Le Fort III
Cause -
Due to force from the lateral direction with a severe impact.
Here , the initial impact is taken by Zygomatic bone
resulting in depressed fracture. Then entire middle third will
then hinge about the fragile ethmoid bone and the impact
will then be transmitted to the contralateral side resulting in
laterally displaced zygomatic fracture of opposite side.
(Craniofacial dysjunction)

26. FRACTURE LINE -
• Line commences near the
frontonasal suture, causes
dislocation of the nasal
bones and disruption of
cribriform plate of the
ethmoid bone.Then line
crosses both the nasal bones
and frontal process of
maxilla, near the frontonasal
and frontomaxillary sutures
and then traverses the upper
limit of the lacrimal bones .

27. • continuing posteriorly, the
line crosses the thin orbital
plate of the ethmoid bone
constituting part of the
medial wall of the orbit. As
optic foramen is surrounded
by a dense ring of bone,
Then fracture line gets
deflected downward and
laterally to reach the medial
aspect of the posterior limit
of the inferior orbital fissure.

28. • From this point , fracture
descends across the upper
posterior aspect of maxillae in
the region of sphenopalatine
fossa and upper limit of
pterygomaxillary fissures and
fractures the roots of pterygoid
laminae at its base.

29. From anterior and lateral aspect of
inferior orbital fissure, line passes
across the lateral wall of orbit ,
adjacent to the junction of zygomatic
bone with greater wing of sphenoid
.The fracture line seperates
zygomatic bone from frontal bone
near suture and then inclines laterally
, running abruptly downwards across
the infratemporal surface, thus in
effect joins the previous line of
fracture seen on medial wall of orbit .

30. The entire middle third is thus
detached from the dense cranial
base.

31. CLINICAL ASSESSMENT OF MIDFACE FRACTURES

76. Summary of Suspension wiring according to fracture site
Type of Suspension Wire Type of Le Fort Fracture
1. Frontal
a. Central Le Fort III & II
b. Lateral Le Fort III & II
2.
Circumzygomatic
Le Fort I & II
3. Zygomatic Le Fort I
4. Infraorbital Le Fort I
5. Piriform Aperture Le Fort I

77. DISADVANTAGES OF SUSPENSION WIRING
• Incomplete fixation of fractured fragments
• Insufficient visualization of fractures by closed
reduction
• Compression against the cranial base
• No 3-dimensional stability
• Patients dislike intra-oral splints as it hinders
oral hygiene maintainence.

78. Internal Fixation
Direct Osteosynthesis -
1. Interosseous Wires.
2. Plates and Screws.

79. Direct osteosynthesis
Intraosseous Wires-
1. Maxillary (Lefort –I )
2. Zygomaticomaxillary (Lefort –II)
3. Frontonasal (LeFort –II &III)
4. Zygomaticofrontal (Lefort III)
5. Zygomatic bone (comminuted)

80. Disadvantages -
 Non rigid type of osteosynthesis
 No 3 dimensional stability, it provides only
monoplane traction.
 IMF is always needed
 Interfragmentary pressure can not be controlled.
 Under functional stress, wire loses rigidity, direction
control and surface contact.
 Delayed healing because of micromovement at
fracture site.

81. Direct osteosynthesis-
2. Plates & Screws for midface fractures -
 Stainless steel mini-plating system
 Titanium mini-plating system
 Vitallium, Cobalt chromium, molybdenum alloy plates
 Bioresorbable plating system.

82. BONE PLATE OSTEOSYNTHESIS
Advantages –
1. Simple & less intraoperative time
2. Intraoral approach is sufficient
3. Postoperative IMF is not needed or period of
IMF is reduced.
4. Three dimensional stability and early return of
function.

101. PRINCIPLES OF MAXILLARY
RECONSTRUCTION
• Miniplates can bridge gaps of up to approximately 0.5cms
• Gaps >0.5cms – bone grafts
• Bone grafts bridging the gap should be wedged
underneath the plate & held in place with screws fixed
from plate directly into the graft.

102. IMMEDIATE BONE GRAFTING
Buttress reinforcement retained by plates or screws can
assist in restoring maxillary height & preventing
Contour deficiencies.
• Rib graft
• Iliac crest
• Calvaria
• Mandibular bone graft
• Alloplastic bone graft

103. CONCLUSION:
Le fort fractures are common in the trauma patient. They
require accurate radiologic diagnosis and surgical
management to prevent severe functional debilities and
cosmetic deformity.
A thorough understanding of the anatomy, craniofacial
buttresses and treatment options will give the maxillofacial
surgeon the optimal tools for achieving a successful result.
