Area of Science:

  • Neurosurgery
  • Medical Imaging
  • Surgical Navigation Systems

Context:

  • Computer-aided surgery (CAS) in endonasal sinus surgery faces challenges with patient head mobility and referencing time.
  • Existing CAS systems require improvements in accuracy and efficiency for complex procedures.

Purpose:

  • To evaluate the accuracy, usability, and applicability of a novel non-invasive, frameless, LED-based autoregistration mask for navigated endonasal sinus surgery.
  • To compare the performance of the LED autoregistration mask against the gold standard of titanium screw markers.

Summary:

  • The LED autoregistration mask was tested in cadaver and patient studies, demonstrating high precision and simple usability.
  • Accuracy measurements using Euclidean distance showed a total accuracy of 2.22 +/- 0.91 mm.
