(Fig. 9) Persistent complications of zygomatic-complex fractures
The most frequent complication of zygomatic complex
fractures was infra-orbital paraesthesia in 27 cases
(54%). This was followed by 3 cases (6%) in asymmetry
(cheek flattening). Two cases (4%) had limitation of
mandibular movement. Persistent diplopia and changes
of visual acuity was seen in one case (2%) (fig. 9).
Conclusion
This study presents information that can be
valuable in describing the pattern and spectrum
of zygomaticomaxillary complex fractures in local
population. Since the assault, the leading cause of facial
trauma, are usually associated with greater severity of
injuries, treatment approach needs to be comparatively
aggressive e.g. exposure of fracture sites and internal
fixations, for better aesthetic and functional restoration.
However, the four most important considerations
in treating zygomatic complex fractures are proper
reduction, adequate stabilization, adequate orbital
floor reconstruction (when necessary), and adequate
handling/positioning of periorbital soft tissue which will
provides the most accurate and satisfactory postoperative
results. Variance in treatment may exist because therapy
depends upon the type and severity of fracture, the time
since injury, and the surgeon’s personal experience. The
prognosis of zygomatic complex fractures is influenced
by delay between time of injury and treatment. The
timing of surgery is dependent on the general health
of the patient and the presenting signs and symptoms.
Ideally management of zygomatic complex injuries
should be undertaken after residual oedema has
subsided and a thorough pre-operative ophthalmic
assessment has been performed. As revealed in this
study, only 72% of patients received surgical intervention
to treat their injury.
