Pilot Clinical Study Using Pre-operative Simulation for Patients Undergoing Cochlear Implant

NCT04588870 · Status: WITHDRAWN · Phase: NA · Type: INTERVENTIONAL

Last updated 2024-02-07

No results posted yet for this study

Summary

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.

Conditions

  • Sensori-Neural Deafness

Interventions

DEVICE

Pre operative computer based cochlear implant surgical simulation

Prior to surgery, the surgeon will perform virtual cochlear implant surgery on patient specific imaging data within a computer simulation program. The surgeon will be able to iterate the procedure on the simulator until achieving the best electrode array location is achieved with respect to scalar location and modiolar distance. A written and graphical surgical plan will then be developed that the surgeon can use in the actual surgery.
