Area of Science:

  • Otorhinolaryngology
  • Medical Technology
  • Surgical Navigation

Background:

  • Augmented reality (AR) integrates preoperative imaging with live surgical views.
  • Scopis Hybrid Navigation is a surgical navigation system featuring AR for endoscopic sinus surgery (ESS).

Purpose of the Study:

  • To evaluate the utility and accuracy of AR-enhanced surgical navigation in a cadaveric model of ESS.
  • To assess the potential of AR to improve frontal recess surgery and reduce complications.

Main Methods:

  • Predissection planning using Scopis Hybrid Navigation software.
  • Endoscopic sinus surgery dissection on human cadaveric specimens with electromagnetic surgical navigation.
  • Overlaying 3D models and annotations of critical anatomy onto endoscopic views.

Main Results:

  • AR image accuracy relative to anatomy was better than 1.5 mm.
  • The trajectory targeting tool guided instrument placement along the frontal sinus outflow pathway.
  • AR highlighted critical structures like the optic nerve and internal carotid artery.

Conclusions:

  • AR-enhanced surgical navigation was easily deployed in ESS cadaveric models.
  • This technology can facilitate identification and cannulation of the frontal sinus outflow pathway.
  • AR can reduce surgical complications by highlighting "anti-targets" and improving navigation.
