Abstract
Background: Zygomaticus major is one of the muscles of facial expressions and is also known as musculus
zygomaticus major, the greater zygomatic muscle, as well as musculus zygomaticus. There are so many variations
in the insertion of this muscles and may leads to the formation of dimple in the cheek region. This particular
property of this muscle is quiet interesting and became the background of this study.
Materials and Methods: Present study was done among 10 cadaveric hemi faces belongs to the department of
anatomy Tagore Medical College to find the occurrence of bifid zygomaticus major which is responsible for
dimple formation in cheeks.
Result: Among the 10 hemi faces we found only 2 faces with bifid zygomaticus major along its insertion.
Conclusion: Even though bifid zygomaticus major is considered as a developmental defect, the dimple in cheek
formed by it is always measured as a mark of beauty. So learning more about the muscle and its variation paved
ways to produce artificial dimples in the face to beautify it.
