Abstract

Technical advances in computer image analysis have made possible three-dimensional(3D) surface Informations of anatomic structures from contiguous axial CT slices. We have recently utilized this 3D CT reconstruction with spiral CT scanner in 6 consecutive patients with primary or secondary craniosynostosis to assess the presence and extent of synostosis, associated calvarial deformity and to facilitate surgical planning of the craniectomy site. High resolution 3-mm contiguous CT sections were obtained and 3D shaded-surface reconstruction image generated after reformation at 2-mm interval. In each case 3D CT demonstrated the exact extent of synostosis, and in 3 cases it was confirmed by surgical inspection. 3D CT images facilitated surgical planning by precisely localizing the proper site for craniectomy. Three-dimensional CT with shaded-surface display may be a useful adjunct to imaging and surgical planning in the patients with craniosynostosis, as well as a useful follow-up imaging study during observation or after surgery.
