- Background: While endoscopic skull base surgery (ESBS) has emerged as an alternative surgical
option, the limited field of view of the endoscope may lead to the surgeon's fatigue and
Methods: The developed navigation system includes extended augmented reality (AR), which
can provide an extended viewport to a conventional endoscopic view by overlaying 3D anatomical models generated from preoperative medical images onto endoscope images. To enhance the
accuracy of the developed system, we adopted state‐ of‐ the‐ art endoscopic calibration and
tracking techniques based on an optical tracking system.
Results: The mean spatial errors of AR was ~1 mm, which falls in the acceptable range of
accuracy for ESBS. For the simulated surgical tasks with the developed system, the number and
duration of error events were decreased.
Conclusions: The results show that the human subject can perform the task more precisely
and safely with the developed AR‐ based navigation system than with the conventional endoscopic system.
