Stability in correction of hypertelorbitism and Treacher Collins syndromes.
In the authors' experience, correction of hypertelorbitism either by facial bipartition or by moving only the orbits has proved to be very stable. This is based on the design of the osteotomies and the use of the frontal bar. On the contrary, the rotation of the midfacial segment combined with mandibular lengthening for the correction of Treacher Collins has a strong tendency to relapse because of the backward pull of the soft tissues. Primary stability in these cases depends on the quality of bone grafts, their placement, and skeletal fixation.
