To compare the accuracy of 3 computer-aided surgery systems for maxillofacial reconstruction.
Evaluation of 3 computer-aided surgery systems: StealthStation, VectorVision, and Voxim.
The University of California, Davis, Department of Otolaryngology computer-aided surgery laboratory.
Four fresh cadaveric heads.
Main Outcome Measure
Mean target registration error.
The StealthStation was the most accurate (mean [SD] target registration error, 1.00 [0.04] mm), followed by VectorVision (1.13 [0.05] mm) and then Voxim (1.34 [0.04] mm). All values met statistical significance (P < .05).
Measurable accuracy differences were found among the navigation systems evaluated. The StealthStation was the most accurate. However, the differences are small, and the clinical significance for maxillofacial reconstruction is negligible.
