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.
