Abstract:
Patients with Apert syndrome show hypertelorism and midfacial hypoplasia, and their features are significantly improved through facial bipartition surgery. In addition, because patients with Apert syndrome demonstrate cranial deformity as well as other deformities, they require multiple surgical interventions throughout their development. We present herein a girl with Apert syndrome for whom subcranial facial bipartition was performed. We could not use the coronal approach because she had a terribly cicatricial scalp and wide calvarial defects caused by previous cranial surgeries carried out at another institution. Therefore, we used the glabellar reverse V-shaped approach and temporal approaches in place of the standard approach. She enjoyed a complication-free intraoperative and postoperative course, and left the hospital on postoperative day 10. Her midfacial segment was repositioned 6 mm anteriorly and 12 mm inferiorly on the cephalometric measurement. Her interpupillary distance was altered from 83 mm preoperatively to 76 mm postoperatively. The reverse V-shaped glabellar approach permits more relaxation of the nasal skin and nasal augmentation that is more reliable, although an inconspicuous scar remains in the prominent area. The temporal approach is also useful, enabling easy zygomatic arch osteotomy and secure pterygo-maxillary separation for pterygo-maxillary separation through an oral approach, allowing chiseling toward the skull base.

Cranial Bones: Superior and Posterior View
The frontal bone is the single bone that forms the forehead. At its anterior midline, between the eyebrows, there is a slight depression called the glabella. The frontal bone also forms the supraorbital margin of the orbit. Near the middle of this margin is the supraorbital foramen, the opening that provides passage for a sensory nerve to the forehead. The frontal bone is thickened just above each supraorbital margin,...
Cranial Bones: Lateral View
The temporal bone forms the lower lateral side of the skull. The temporal bone is subdivided into several regions. The flattened upper portion is the squamous portion of the temporal bone. Below this area and projecting anteriorly is the zygomatic process of the temporal bone, which forms the posterior portion of the zygomatic arch. Posteriorly is the mastoid portion of the temporal bone. Projecting...
