treatment of the facial clefts can be divided in different areas of the face: the cranial anomalies, the orbital and eye anomalies, the nose anomalies, the midface anomalies and the mouth anomalies. Treatment of the cranial anomalies The most common cranial anomaly seen in combination with facial clefts is encephalocele. Encephalocele The treatment of encephalocele is based on surgery to repair the bony gap and provide adequate protection of the underlying brain. The question remains if the external brain tissue should be put back into the skull or if it is possible to cut off that piece of brain tissue, because its claimed that the external piece of brain tissue often isn’t functional, with the exception of a basal encephalocele, in which the pituitary gland can be found in the mouth. Treatment of orbital / eye anomalies The most common orbital /eye anomalies seen in children with facial clefts are colobomas and vertical dystopia. Coloboma The coloboma which occurs often in facial clefts is a cleft in the lower or upper eyelid. This should be closed as soon as possible, to prevent drought of the eye and a consecutive loss of vision. Vertical orbital dystopia Vertical orbital dystopia can occur in facial clefts when the orbital floor and/or the maxilla is involved in the cleft. Vertical orbital dystopia means that the eyes do not lay on the same horizontal line in the face (one eye is positioned lower than the other). The treatment is based on the reconstruction of this orbital floor, by either closing the boney cleft or reconstructing the orbital floor using a bone graft. Hypertelorism There are many types of operations which can be performed to treat a hypertelorism. 2 options are: box osteotomy and facial bipartition (also referred to as a median fasciotomy). The goal of the box osteotomy is to bring the orbits closer together by removing a part of the bone between the orbits, to detach both orbits from the surrounding bone structures and move both orbits more to the centre of the face. The goal of the facial bipartition is not only to bring the orbits closer together, but also to create more space in the maxilla. This can be done by splitting the maxilla and the frontal bone, remove a triangular shaped piece of bone from the forehead and nasal bones and pulling the two pieces of forehead together.
