Identity of orbitozygomatic muscle

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 orbiculairs 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).
