Facial Injuries
 Dental Terminology
http://entbgh.blogspot.com/
Overview
 Classic tripod, orbital floor, LeFort
fractures better thought of as
orbitozygomaticomaxillary fractures
 Precise anatomic reduction
is key
 Goal is functional
and cosmetic
rehabilitation
http://entbgh.blogspot.com/
Epidemiology

Males : Females -- 4:1

to decrease and avoids shortening of

between 5-7 days
for resolution of
edema
 Pre- or intra-
operative steroids
can help with
edema

shorten

Zygoma
 reduction only - Minimally displaced, non
comminuted
 plating of lateral antrum, orbital rim, ZF
suture, and even the zygomatic arch - for
Increasing amounts of displacement &
comminution

with reduction, then plate it after other
areas stabilized

Coronal and Lower Eyelid Incisions
http://entbgh.blogspot.com/
Treatment
http://entbgh.blogspot.com/
Treatment
 Goal is functional and cosmetic
restoration
 Treatment must be individualized
 Various factors can affect management
strategies
 Multi-trauma
 Concomitant mandible injury
 Only-seeing eye
http://entbgh.blogspot.com/
Maxillary Fractures
Management
 Rigid Internal
Fixation
 Frontal Bone as a Guide
 Mandibuar Ramus Dictates
Facial Height
 Stabilize Vertical
Buttresses
 Bone Grafts If Necessary
http://entbgh.blogspot.com/
Maxillary Fractures
Palatal Fractures
 8% of LeFort fractures
 Younger vs. Older
 <30 years

midline fracture
 >30 years

sagittal fractures adjacent to midline or alveolus
http://entbgh.blogspot.com/
Maxillary Fractures
Palatal Fractures
 Stabilize before IMF
 Open reduction of palatal roof
 Pyriform aperture plate to unite
maxillary segements
 Dental splints to prevent occlusion

Associated Injuries
 Brandt et al 1991
 59% caused by MVA had
intracranial injury
 10% caused by fall/beating had
intracranial injury
http://entbgh.blogspot.com/
Associated injuries
 Haug et al 1990
 402 patients
 Zygoma fractures:
 Lacerations 43%
 Orthopedic injuries 32%
 Additional facial fractures 22%
 Neurologic injury 27%
 Pulmonary, abdominal, cardiac 7%, 4.1%, 1%
http://entbgh.blogspot.com/
 Maxillary fractures:
 Lacerations and abrasions 75%
 Orthopedic injury 51%
 Other facial fractures 42%
 Neurologic injury 51%
 Pulmonary 13%, abdominal 5.7%, cardiac
3.8%
http://entbgh.blogspot.com/
Midface
 “Rigid” fixation misnomer with small
plates and thin bones
 Semirigid fixation (wire) sometimes
preferable
 Early function can be achieved with soft
diet only
http://entbgh.blogspot.com/
Vertical Buttress Algorithm
http://entbgh.blogspot.com/
Midface Disimpaction
 May be necessary to restore
facial dimensions before fixation
http://entbgh.blogspot.com/
Palate
Fracture
 Wire can be
placed
posteriorly for
stabilization
before triangular
reduction
http://entbgh.blogspot.com/
ORIF of Midface
http://entbgh.blogspot.com/
Order of Repairs
 Work from stable to unstable
 Use occlusion as guide
 Generally stabilize mandible, zygoma
and palate before midface before orbit
and NOE
http://entbgh.blogspot.com/
Order of
Repairs
http://entbgh.blogspot.com/
Treatment of maxillary
fractures
 Early repair
 Single-stage
 Extended access approaches
 Rigid fixation
 Immediate bone grafting
 Re-suspension of soft tissues
http://entbgh.blogspot.com/
Maxillary fractures
 Steps of reconstruction-Rohrich and
Shewmake
 Reestablish facial height and width
 IMF with ORIF of mandible
 Zygomatic arch reconstruction restores facial
width and projection
 Reconstruction continues from stable bone to
unstable and from lateral to medial
http://entbgh.blogspot.com/
Internal fixation vs. traditional
methods
 Klotch et al 1987
 43 patients
 22 treated with ORIF using AO
miniplates
 21 treated with combination of
intermaxillary fixation, and/or
interosseous wiring, and/or primary
bone grafting
http://entbgh.blogspot.com/
 Most severe injuries in rigid internal
fixation group
 Shorter IMF, early return to diet, lower
percentage of tracheotomy
 No plate infections
http://entbgh.blogspot.com/
 Haug et al 1995
 134 patients treated by
maxillomandibular fixation or rigid
internal fixation
 Postoperative problems in 60% vs 64%
http://entbgh.blogspot.com/
Treatment of maxillary
fractures
 Early repair
 Single-stage
 Extended access approaches
 Rigid fixation
 Immediate bone grafting
 Re-suspension of soft tissues
http://entbgh.blogspot.com/
Approaches
 Circumvestibular
 Facial degloving
 Bicoronal
 Transconjuctival

Cutting Edge Topics
 Bioresorbable plates
 Intraoperative CT
 3-D CT reconstruction
 Endoscopic assistance
http://entbgh.blogspot.com/
Conclusion
 Goal is functional and cosmetic
rehabilitation
 Precise anatomic restoration key
 Treatment tailored to each individual
 Knowledge of anatomy and techniques
will lead to superior results
http://entbgh.blogspot.com/
Conclusions
 High index of suspicion for associated
injuries- especially ocular
 Assessment of buttress system
 Wide exposure via cosmetically
acceptable incisions
 Rigid fixation
 Soft tissue resuspension
http://entbgh.blogspot.com/
