36 patients will be enrolled in a pilot trial. Eligible patients (receiving CI at OSU) that consent to participate into the study will be enrolled. A simulation with visualize cochlear substructures will be created for each patient, and surgeon will conduct virtual surgery with various cochlear implant electrode types and using different techniques for optimal positioning. Based on the feedback from the simulation platform, the surgeon will find the optimal CI electrode and surgical technique using the virtual simulation and a formal plan will be recorded to guide the actual surgery. Patient demographic information, medical history and pre op audiogram will be collected once enrolled. Post-op images will be used to identify the actual electrode location (scalar location (SL), modiolar distance (MD) and and angular insertion depth (AID). At 6- and 12-months post-op, word score (CNC) will be obtained as primary clinical outcomes and AZBio scores will also be obtained and evaluated as a secondary clinical outcome. All outcomes data to be collected for SA3 are considered as part of routine clinical care for patients undergoing CI at our institution. The prospective data collection plan will ensure these data will be collected timely with high quality. OSU IRB approval has been obtained for this study (OSU IRB# 2020H0080: Virtual Reality simulation for patient specific surgical rehearsal in cochlear implantation - OSU#2) pending additional amendments as needed.
