Augmented reality-enhanced navigated neuroendoscopy offers accurate and safe intraventricular surgery. This technology improves visualization by overlaying planning data onto the endoscopic view, enhancing surgical outcomes.

Area of Science:

  • Neurosurgery
  • Medical Imaging
  • Surgical Navigation

Background:

  • Intraventricular neuroendoscopy planning, including entry point and navigation, is increasingly critical.
  • Advancements in navigated neuroendoscopic solutions are continuously enhancing capabilities.

Purpose of the Study:

  • To experimentally measure the accuracy of augmented reality-enhanced navigated neuroendoscopy.
  • To report the initial clinical experience with this technology for intraventricular pathologies.

Main Methods:

  • AR-enhanced navigation was tested using a 3D-printed head model with CT-based tumor segmentation.
  • Navigation software superimposed pre-planned regions of interest and trajectories onto the endoscopic view.
  • Accuracy was assessed by measuring deviations between planned and visualized targets; the technique was applied in 29 clinical cases.

Main Results:

  • Experimental accuracy showed a deviation of 1.2 ± 0.4 mm.
  • Clinical applications included cyst fenestrations (18), biopsies (10), third ventriculostomies (7), and stent placements (6).
  • Postoperative cyst volume reduction averaged 47%, biopsy yield was 100%, and reoperations were needed in only two cases with minimal complications.

Conclusions:

  • Augmented reality-navigated neuroendoscopy is accurate and clinically feasible.
  • Integrating planning information into the endoscopic view can enhance safety and efficacy in intraventricular surgery.
