Application of the Threedimensional CT Scan to the Reconstruction of Craniofacial Deformities.

New developments in computerised tomography (CT) imaging technology have paralleled advances in craniofacial surgical techniques. The ability to reconstruct congenital, neoplastic, and traumatic deformities is dependent upon good pre-operative assessment. Understanding the spatial relationship of a given deformity is limited with conventional two-dimensional CT scans.
