High‐Resolution Visualization of the Human Semicircular Canals Using Optical Coherence Tomography

The semicircular canals are essential sensors of the vestibular organ. Current clinical in vivo imaging techniques lack the resolution needed to visualize critical vestibular microstructures, such as the membranous labyrinth and crista ampullaris. Optical coherence tomography (OCT) has emerged as a promising imaging technique, offering high‐resolution, cross‐sectional visualization of inner ear structures, particularly within the cochlea. In this study, we assess the feasibility of OCT for imaging the vestibular system in human temporal bones and present the first comprehensive OCT atlas of the human vestibular organ confirmed on micro‐CT imaging. This atlas may support future research by providing detailed anatomical references. This technique holds promise for future diagnostic applications and for improving the accuracy of surgical procedures, such as vestibular implant surgery.
