Abstract:
Our exploration disclosed 17 (40%) stranded muscles of 42 hemifacial specimens of Korean cadavers. We name this distinct muscle "Orbitozygomatic Muscle (OZM)" that is either an aberrant orbicularis oculi muscle or a separate muscle. A triangular space bounded superiorly by the lowest edge of the orbicularis oculi muscle (OOM), laterally by Zygomaticus Minor, and inferiorly by OMZ gives way to neurovascular bundle and suborbicularis oculi fat pad (SOOF).

Cranial Bones: Superior and Posterior View
The frontal bone is the single bone that forms the forehead. At its anterior midline, between the eyebrows, there is a slight depression called the glabella. The frontal bone also forms the supraorbital margin of the orbit. Near the middle of this margin is the supraorbital foramen, the opening that provides passage for a sensory nerve to the forehead. The frontal bone is thickened just above each supraorbital margin,...
