Abstract
The aim of this study was to clarify the arrangement of the zygomaticus major muscle, and to describe morphology of zygomaticus minor muscle. After a detailed dissection, the zygomaticus muscles were observed in 66 embalmed cadavers. It was found that the insertion of zygomaticus major was divided into superficial and deep bands(42/70, 60%). Zygomaticus minor was inserted not only upper lip also alar portion(5/54, 9.2%). The arrangement and insertion patterns of the zygomaticus muscles in this study are expected to provide critical information for understanding of smile pattern and treatment of fold.
