Facial bipartition first involves splitting the frontal bone from the supraorbital rim. Then the orbits and the midface are released from the skull-base using monoblock osteotomy. Then a triangular shaped piece of bone is removed from the midline of the midface. The base of this triangular segment lies above the orbita and the apex lies between the upper incisor teeth. After removing this segment it is possible to rotate the two halves of the midface towards each other, thus resulting in reduction of the distance between the orbits. It also results in leveling out the V-shaped maxilla and therefore widening of it.
