title: [Syndromes 7. Hypertelorism (Greig syndrome)].
abstract: Hypertelorism is an increased distance between the orbits. Most evident symptom is the increased intercanthal distance. It can be caused by congenital deformities (facial clefts, encephaloceles, enlarged ethmoïds) and by trauma. Three degrees are differentiated. Grade one and two can be corrected with a small risk for complications. If there is vertical orbital dystopia it has to be corrected by a transcranial procedure, as is necessary in grade 3.
