Recent advances in imaging have led to high‐resolution computerized tomography (CT) scanning with exquisitely detailed slice images of the skull and three‐dimensional (3‐D) surface reconstructions using computer software. It is possible to use CT scans to acquire morphologic information about the skull in a convenient digital form and to derive 3‐D measurements from surface reconstruction images. Unfortunately, no effort has been made to date to test the validity of these measurements on laboratory specimens, and no compelling evidence is available from phantom studies to indicate the nature and magnitude of the errors inherent in the measurement technique. We have performed a pilot study to quantify the morphology of the skull based on surface features that can be found in CT scans and 3‐D reconstructions. Comparative measurements were obtained from five skulls (two normal and three with dysmorphology) with calipers and a 3‐D electromagnetic digitizer. These measurements were statistically compared with those based on original CT scan slices and reformatted 3‐D images. It is concluded that 3D‐CT measurements techniques are superior to those in which measurements are obtained directly from the original CT slices; 3‐D CT methods, however, must be significantly improved before measurements based on these techniques can be used in studies that require a high degree of precision. The results are used to indicate the most fruitful areas of future study
