We verified an accuracy of the new navigator for paranasal sinus surgery that we have developed. Using a human model, we performed a simulated endoscopic sinus surgery, and measured the errors. The result indicated that the average error was 1.02mm in the three-dimensional plane. When we verify the error of surgical navigator, caution should be paid with the thickness of the slices, the field of view value, and the partial volume effects in X-ray computed tomography.
