Presented herein are substantially automated techniques that enable an electro-acoustic or other hearing prosthesis implanted in a recipient to use objective measurements to determine when the recipient is likely experiencing sound perception changes. Once one or more perception changes are detected, the hearing prosthesis may initiate one or more remedial actions to, for example, address the perception changes. As described further below, the one or more remedial actions may include adjustments to the recipient's operational map to reverse the one or more perception changes.

Techniques and electrode array designs can facilitate implantation of a vestibular electrode array proximate a target treatment location of the recipient’s vestibular system. An example vestibular electrode array can include a variety of mechanisms to provide fine control of the vestibular electrode array’s position in the vestibular space. Further, the position can be guided by real time feedback mechanisms, such as fluoroscopy or electrophysiological measures to assist with optimizing the position of the vestibular electrode array.
