She presented with "long face syndrome" with excessive midface height, excessive dental show in repose, and malocclusion with anterior open bite (Fig 1).
Virtual planning work flow. (a) Preoperative 3D reconstruction demonstrating excessive maxillary height and anterior open bite. (b) Planned intermediate position of the maxilla after performing a Le Fort I osteotomy with impaction and using a prefabricated splint to move the maxilla on the basis of the current position of the mandible. (c) Planned final position of the mandible after performing bilateral sagittal split osteotomies and using a second splint to move the mandible on the basis of the new position of the maxilla.
