MIDDILE THIRD OF FACE
The middle third of the face is the area bounded by :
superiorly by a line drawn from the zygomaticofrontal suture
across the frontonasal &frontomaxillary suture to the
zygomaticofrontal suture at the opposite side.
Inferiorly by the occlusal plane or the alveolar ridge, and
Posteriorly as far as the frontal bone above and body of
sphenoid below.

Le Fort I fracture
Violent force over a more extensive area above the level of the
teeth will result in Le Fort I fracture
Horizontal fracture line seen above the apices of the maxillary
teeth, detaching the tooth bearing portion of the maxilla from
the rest of the facial skeleton.
The fractured fragment is freely mobile and displacement will
depend on the direction of the force.
Depending upon the displacement, a variety of occlusal disharmony
can be seen in this type of Le Fort I fracture.
Dr.GPK, OMFSDr.GPK, OMFS 2121
Le Fort I fracture
The fracture line commences at the point on the lateral margin of the
anterior nasal aperture, passes above the nasal floor, and it
passes laterally above the canine fossa and traverses the lateral
antral wall, dipping 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 thrid and upper 2 /3rds.
At the same time, from the same starting point, the fracture also passes
along the lateral wall of the nose to join the lateral line of
fracture behind the tuberosity.

Pyramidal or subzygomatic fracture
Violent force in the central region extending from glabella
to the alveolus results in pyramidal fracture
Dr.GPK, OMFSDr.GPK, OMFS 3030
Le Fort II fracture
The fracture line runs below the frontonasal suture from the thin
middle area of the nasal bones down on either side, crossing the
frontal process of the maxillae and passes anteriorly across the
lacrimal bones anterior to nasolacrimal canal. From this point the
fracture line passes downward, forward and laterally crossing
the inferior orbital margin in the region of zygomaticomaxillary
suture. May or may not involve the infra orbital foramen. The
fracture line extends downward and forward and lateral to the
transverse wall of the antrum, just medial to the
zygomaticomaxillary suture line.

Le Fort III fracture
The fracture line begins at the frontozygomatic suture along the
lateral aspect of the internal orbit along the sphenozygomatic
suture line to the inferior orbital fissure, extends medially
across the floor of the orbit up the medial wall of the orbit
towards the dorsum of the nose where it crosses and proceeds to
the opposite side in the same manner. Various amounts of the
pterygoid plates will usually remain attached to the posterior
maxilla.

GOLDEN HOURGOLDEN HOUR
The vernacular term “golden hour” is widely attributed to
R. Adams Cowley, founder of Baltimore’s Shock Trauma
Institute.
In a 1975 article, he stated, “the first hour after injury will
largely determine a critically-injured person’s chances for
survival.”

Management of midface fracture
Maxillofacial Injuries
Treatment divided into following phases –
Emergency or initial care
Early care
Definitive care
Secondary care or revision
Dr.GPK, OMFSDr.GPK, OMFS 5959
Management of midface fracture
Emergency treatment and stabilization of the patient.
Definitive treatment with reduction and fixation
Dr.GPK, OMFSDr.GPK, OMFS 6060
SOFT-TISSUE LACERATIONS
The most common priority for patients with fractures of
the middle third is repair of soft –tissue lacerations,
particularly of the face. Ideally these should be sutured
before too much oedema has occurred; that is within 1- 8
hours of injury.

Initial management
The primary survey progresses in a logical manner based on the
ABC’s & D,E.
Airway maintenance with cervical spine control
Breathing and adequate ventilation
Circulation with control of hemorrhage
The letters D and E have also been added:
Degree of consciousness
Exposure of the patient via complete undressing to avoid
overlooking injuries camouflaged by clothing
Dr.GPK, OMFSDr.GPK, OMFS 6363

Treatment of Blood Loss & Shock
Extensive vascularity of head & neck may lead to massive blood
loss
Monitor vital signs closely – Intravenous infusion
Penetrating injuries need to be explored – Arteriogram
Esophagram
Hemorrhage most common cause of shock after injury
Multiple injury patients have hypovolemia
Goal is to restore organ function & perfusion
External bleeding controlled by direct pressure over bleeding site
Gain prompt access to vascular system with IV catheters
Fluid replacement – Ringer’s Lactate
Normal saline – Transfusion

Stabilization of associated injuries
C spine injury is primary concern with all maxillofacial‐
trauma victims
Any patient with injury above clavicle or head injury
resulting in unconscious state
Any injury produced by high speed
Signs/symptoms of C Spine injury‐
• Neurologic deficit
• Neck pain

  • 21. Le Fort I fracture Violent force over a more extensive area above the level of the teeth will result in Le Fort I fracture Horizontal fracture line seen above the apices of the maxillary teeth, detaching the tooth bearing portion of the maxilla from the rest of the facial skeleton. The fractured fragment is freely mobile and displacement will depend on the direction of the force. Depending upon the displacement, a variety of occlusal disharmony can be seen in this type of Le Fort I fracture. Dr.GPK, OMFSDr.GPK, OMFS 2121
  • 22. Le Fort I fracture The fracture line commences at the point on the lateral margin of the anterior nasal aperture, passes above the nasal floor, and it passes laterally above the canine fossa and traverses the lateral antral wall, dipping 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 thrid and upper 2 /3rds. At the same time, from the same starting point, the fracture also passes along the lateral wall of the nose to join the lateral line of fracture behind the tuberosity. Dr.GPK, OMFSDr.GPK, OMFS 2222
  • 25. Le Fort I fracture Mostly bilateral Sometimes unilateral depending upon the displacement, direction and severity of force May occur as single entity or with Le Fort I and II fractures. Dr.GPK, OMFSDr.GPK, OMFS 2525
