importance  Image guidance is an important adjunct for endoscopic sinus and skull base surgery.

 

However, current systems require bulky external tracking equipment, and their use can interrupt efficient surgical workflow.

 

Objective  To evaluate a trackerless surgical navigation system using 3-dimensional (3D) endoscopy and simultaneous localization and mapping (SLAM) algorithms in the anterior skull base.

 

Design, Setting, and Participants  This interventional deceased donor cohort study and retrospective clinical case study was conducted at a tertiary academic medical center with human deceased donor specimens and a patient with anterior skull base pathology.

 

Exposures  Participants underwent endoscopic endonasal transsphenoidal dissection and surface model reconstruction from stereoscopic video with registration to volumetric models segmented from computed tomography (CT) and magnetic resonance imaging.
