The cheekbones are the structures of the facial bones that define the contour of the middle portion of the face. For convenience, they can be divided into the front cheekbone and the side cheekbone. The contour of the front cheekbone is formed by the body of the cheekbone, while the contour of the side cheekbone is formed by the cheekbone arch.

The contour of the front cheekbone is refined into an appropriately smooth curve by removing the overly protruding area while maintaining a certain amount of volume.

To narrow the contour of the widened side cheekbone, the cheekbone arch is moved inward into the empty space and brought together. If the cheekbone arch is brought together as far inward as possible, the width of the face on one side can be reduced by nearly 15 mm.
By cutting the front body of the cheekbone without removing it, then performing osteotomy and joining part of the osteotomy area so that it bends like bamboo, the width of the side cheekbone can be reduced without creating a gap in the front cheekbone.
