How AR Enhances Cochlear Implant Planning

Cochlear implant surgery planing involves multiple steps: preoperative assessment of te te patient 's cochlear anatomy, selection of thee appropriate implant andd electrode array, and determination of thee optimal inserction traffitory. Each of these stages can benefit from AR- enhanced visualization.

Patient- Specific 3D Modeling

Using high- resolution CT ande MRI data, surgeons can create detaild destructions of thee cochlea, facial nerve, chorda tympani, and ossicles. AR platforms, such as those built on thee contact HoloLens 2 or Magic Leap 2, can render these modele as holoographic overlays. During planning, thee surgeon came examphee thee cochlear duct from any angle, rotate thee model, and metributical distrances - such athee ingene between whne whne the modiolus - with submimetter.
