ABSTRACT
Traditionally, cadaveric studies and plain-film cephalometrics provided information
about craniomaxillofacial proportions and measurements; however, advances in computer
technology now permit software-based review of computed tomography (CT)-based models.
Distances between standardized anatomic points were measured on five dried human skulls
with standard scientific calipers (Geneva Gauge, Albany, NY) and through computer
workstation (StealthStation 2.6.4, Medtronic Surgical Navigation Technology, Louisville,
CO) review of corresponding CT scans. Differences in measurements between the caliper
and CT model were not statistically significant for each parameter. Measurements obtained
by computer workstation CT review of the cranial skull base are an accurate representation
of actual bony anatomy. Such information has important implications for surgical planning
and clinical research.
