The fusion of coronoid process with zygomatic arch
is not often seen.
Surgery included resection of the right inferior orbital rim, the anterior orbital floor, the zygomatic arch
, and the anterior face of the maxilla.
The interesting finding in this study was that no isolated fracture of zygomatic arch

distance from the gnathion after the aboral edge of the hard palate, CI--thickness of the incisor, IBW--width of the braincase, A--breadth of the upper ramus of the zygomatic process of the maxilla, and B--breadth of the zygomatic arch
. Skull measurements were taken with a digital calliper with accuracy of 0.01 mm.
Research of zygomatic arch
pneumatization has particular morphological, as well as clinical significance.
Hyperplasia caused the zygomatic arch
and the zygomatic bone on the right side to expand and become thinner (Figures 1 to 5).
Panoramic radiographs in which the zygomatic arch
was not seen clearly and cases with previous history of maxillofacial fractures or had maxillofacial anomalies were excluded from our study.
For the SBZ technique, a 22G x 1 inch hypodermic needle was inserted perpendicular to the skin in a point located between the caudal margin of the maxilla and the cranial border of the jaw body, ventral to the rostral portion of the zygomatic arch
. The needle was advanced into the pterygopalatine fossa and, when it was considered by the veterinarian to be in close proximity to the maxillary nerve, injection of methylene blue dye was performed (Figure 1).
Closed reduction was the most commonly used treatment method in cases with nasal fractures and isolated zygomatic arch
The right temporal bone fracture with a fractured fragment in the temporomandibular joint (TMJ) space, the right zygomatic arch
fracture, the right greater wing of the sphenoid fracture, the orbital floor fracture, and lateral and medial walls of the right maxillary sinus fracture were reported.
The nerve crosses over the hind part of the zygomatic arch
posterior to the superficial temporal artery (Figure 1(b) and Table 1).
The white area represents the swung anterior maxilla, and the blue area (inferior part of the zygomatic arch
) represents the area removed for visualization purposes.
The bone thickness, confirmed by CT scan (Figure 1), in temporal root of the zygomatic arch
and glenoid fossa were adequate for the fixation of the fossa component of the prosthesis.
Lie the patient in the supine position with shoulder elevated, and rotate the patient's head about 90[degrees] to the contralateral side of the lesion, and keep the zygomatic arch
in the horizontal position; lean the head back about 15[degrees], so as not to oppress the trachea; laterally bend the head 15[degrees] to the contralateral position, to compensate for the upward incline angle along the middle skull base.
