This study demonstrates a novel surgical navigation system using simultaneous localization and mapping (SLAM) for trans-mastoid surgery. The SLAM-based approach achieved high accuracy, showing potential for improved lateral skull base procedures.

Area of Science:

  • Neurosurgery
  • Medical Imaging
  • Surgical Navigation

Background:

  • Traditional surgical navigation often relies on external tracking systems.
  • Simultaneous Localization and Mapping (SLAM) offers a potential trackerless alternative.
  • Skull base surgery demands high precision navigation.

Purpose of the Study:

  • To evaluate the feasibility of a SLAM-based surgical navigation system.
  • To assess its accuracy during combined exoscopic-endoscopic trans-mastoid surgery.
  • To determine the system's performance in a cadaveric model.

Main Methods:

  • Interventional deceased donor cohort study in a tertiary care hospital.
  • Surface models reconstructed from 3D exoscopy/endoscopy video.
  • Volumetric CT models segmented and coregistered with surface reconstructions.

  • Accuracy quantified by reconstruction, registration, and surface-surface errors.

    • Main Results:

    • High-fidelity surface model reconstruction and coregistration achieved.
    • Mean reconstruction error: 0.72 mm.
    • Mean registration errors ranged from 1.43 mm to 1.72 mm.
    • SLAM system maintained accuracy throughout simulated surgical dissection.

    Conclusions:

    • SLAM-based surgical navigation is feasible for trans-mastoid surgery.
    • The system provides accurate localization and maintains accuracy during exoscope/endoscope alternation.
    • This technology has potential for accurate, continuous navigation in lateral skull base surgery without compromising efficiency.
