Abstract
Craniofacial stenoses form a unique syndrome in spite of the extreme diversity of their clinical aspects, such as the Crouzon syndrome, orbital dystopies and hypertelorism. The possibility of surgery for these disorders is still new. The interventions are extremely complex because of the nature of the malformations, which may involve the intrafacial skull. By monobloc orbital osteotomy, the position of the orbit can be corrected in three planes, in the sagittal direction, in craniofacial stenoses, in the vertical direction in orbital dystopia, and in the transverse direction in hypertelorism.
