For structure and support, it is best to inject deep onto the bone at the zygomaticotemporal suture line to have anterolateral lifting and on the malar eminence (the maximal projection point) to give inferior support to the orbit and indirectly improve the sub-orbital hollowing.

This injury is due to a direct blow to the cheek, which may fracture the zygomatic arch in isolation, or cause a ‘tripod’ fracture to the zygo-maticomaxillary (malar) complex that extends through three structures: Superiorly through the zygomaticofrontal suture.Laterally through the zygomatic arch or zygomaticotemporal suture.Medially through the zygomaticomaxillary suture or the infraorbital foramen region.

The zygomaticus major originates from the zygomatic bone just in front of the zygomaticotemporal suture. It passes to the angle of the mouth, blending with the fibers of the orbicularis oris and the levator anguli oris, and merges with the modiolus. The zygomaticus major pulls the angle of the mouth upward and laterally, as seen during laughing. Its vascular supply is mainly via the superior labial artery, a branch of the facial artery. Muscle innervation is via the zygomatic and buccal branches of the facial nerve.

Stress arising from the zygomaticotemporal suture was higher at all angles in the skeletal anchorage model. The stress concentration in the area around the insertion site of the orthodontic anchor screw was low at 0° and 10° and the concentrations in the posterior alveolar bone and palate areas were high, whereas those in the zygomaticomaxillary and zygomaticotemporal sutures were considered to be lower compared with the dental anchorage model. However, stress was found to decrease with increasing angle, reaching its minimum value at 30°. Although zygomaticotemporal suture stress decreases at greater angles, anterior displacement of the ANS increased. Chang Liu et al [29] reported that the frontomaxillary and zygomaticomaxillary sutures play significant roles in rotation and anterior movement of the maxilla, whereas the zygomaticotemporal and pterygopalatine sutures have minimal effects. Our results also suggest that the zygomaticotemporal suture has a negligible effect on anterior displacement of the maxilla.

Specific measurements were defined as follows, zygoma transverse width was defined as the distance between the zygomatic peak point and self-base plane, which was produced by the three midpoints of the three sutures around zygoma, the zygomaticomaxillary suture, zygomaticotemporal suture, and zygomaticofrontal suture. The zygomatic peak point was produced by the ‘create part comparison analysis’ function in 3-matics. While, the zygoma anterior protrusion was defined as the distance from the most anterior point of zygoma to the plane representing the most anterior of frontal bone (Figure 1).
