Monocular Surface Reconstructions in Transcanal Endoscopic Ear Surgery: A Phantom Feasibility Study

Key Points

This research aims to evaluate the feasibility of using monocular images for 3D reconstructions in ear surgery.
Conducted a phantom feasibility study using monocular endoscopic images.
Converted 2D images into 3D surface models of the middle ear anatomy.
Assessed registration accuracy against ground-truth imaging.
Achieved submillimeter registration accuracy for the 3D reconstructions.
Confirmed the feasibility of monocular, endoscope-centric navigation in ear surgery.

Abstract

Simple 2D, monocular endoscopic images can be converted into high-fidelity 3D surface reconstructions of middle ear anatomy, which can be registered to ground-truth imaging with submillimeter registration accuracy. These findings establish the preclinical feasibility of monocular, endoscope-centric navigation for transcanal endoscopic ear surgery.
