Isolated zygomatic arch fracture is rare in zygomaticomaxillary
complex fracture, representing approximately 10% of all cases in the literature.
The most common fracture patterns were zygomaticomaxillary
complex fractures and isolated orbital floor fractures (table 1).
Under general anesthesia an incision was made on anterior border of mandible and the corpus and ramus were exposed on affected side and in upper jaw zygomaticomaxillary
buttress was exposed.
9 Another retrospective study conducted in India showed the most commonly associated fracture was that of zygomaticomaxillary
complex, followed by Le Fort type fractures10.
Another relatively rare cause of trismus is trauma to the zygomatic arch and zygomaticomaxillary
complex, which interferes with movements of coronoid process

fractures were seen in 17 patients (7.
Associated injuries included left frontal lobe injury, anterior and posterior table fractures of the left frontal sinus, and a comminuted left zygomaticomaxillary
In the present study combination of frontozygomatic process and zygomaticomaxillary
buttress was frac-tured in 8.
He was diagnosed having right frontal bone, orbital blow out and zygomaticomaxillary
The prosthesis had entered the orbit in the retrobulbar area and eroded the lateral zygomaticomaxillary
buttress and the orbital floor.
Among her injuries were multiple orthopedic and facial fractures, including fractures of the right zygomaticomaxillary
complex (ZMC) and the nasal bone, as well as extensive soft-tissue envelope trauma.
