Summary We are pioneering the use of intra-operative monitoring of hearing function during cochlear implantation to actively preserve this function in theatre. As part of this monitoring, the surgeon may adjust the electrode’s trajectory actively during implantation to preserve hearing. With newer pre-curved electrode designs that are advanced out of sheaths, it is unclear how these manipulations affect the tip of the electrode array.

Project Details

A goal of modern cochlear implantation is to protect any natural, residual hearing the patient may have. We are pioneering the use of intra-operative monitoring of hearing function during cochlear implantation to actively preserve this function in theatre. As part of this monitoring, the surgeon may adjust the electrode’s trajectory actively during implantation to preserve hearing. With newer pre-curved electrode designs that are advanced out of sheaths, it is unclear how these manipulations affect the tip of the electrode array. The purpose of this project is to investigate changes in the electrode’s position using X-ray and µCT scans in 3d printed cochlear models and donated temporal bones to develop and roll-out a protocol for actively preserving residual hearing during cochlear implantation. The project has a strong possibility for translational research, and you will be working closely with cochlear implant recipients as well as our industry partner (Cochlear Ltd).
