Because this often creates excessive skin between the orbits a midline excision of skin is frequently necessary. This approximates the eyebrows and eye corners and provides a more pleasing look. Facial bipartition
The standard procedure (box osteotomy) was modified by Jacques van der Meulen and resulted in the development of the facial bipartition (or median faciotomy). 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. Because hypertelorism is often associated with syndromes like Apert, hypertelorism is often seen in combination with midface dysplasia. If this is the case, facial bipartition can be combined with distraction osteogenesis. The aim of distraction osteogenesis of the midface is to normalize the relationship between orbital rim to eye and also normalize the position of zygomas, nose and maxilla in relation to the mandible. Soft tissue reconstruction
To create an acceptable aesthetic result in the correction of orbital hypertelorism, it is also important to take soft-tissue reconstruction in consideration.
