[The use of a computer to measure linear and angular variables for an assessment of symmetry of the base of the skull].
The use of a computer is described to make linear and angular measurements of the base of the skull. A group of 19 adult skulls from mediaeval Poland were chosen for this study. The cephalometric analysis defined 11 linear and 9 angular morphological variables. An assessment of method error due to point location by the cursor was made by duplicate determination, and an assessment of symmetry was carried out by comparing angular values derived from basion (ba) for right and left sides of the maxillary dental arch, zygomatic arch and cranial base. The results demonstrate that skull measurements could be recorded with a small method error of 0.2 mm for linear, and 0.2 degrees for angular recordings. Mean values for the 21 variables in the sample were recorded and statistically tested for point placement accuracy using measures of skewness and kurtosis to detect gross distribution errors.
