Presented herein are techniques for monitoring the insertion of an intra-cochlear stimulating assembly for the occurrence of one or more insertion stop conditions. The insertion stop conditions are detectable events indicating that movement of the stimulating assembly into a recipient's cochlea should be at least temporarily stopped. The insertion monitoring is based on objectively measured inner ear potentials, such as acoustically-evoked potentials.

Monitoring stimulating assembly insertion

Presented herein are techniques that make use of objective measurements obtained in response to acoustic stimulation signals. More specifically, at least one measure of outer hair cell function and at least one measure of auditory nerve function are obtained from a tonotopic region of an inner ear of a recipient of a hearing prosthesis. The at least one measure of auditory nerve function and the least one measure of outer hair cell function are then analyzed relative to one another.

Objective determination of acoustic prescriptions

A method, including energizing one or more electrodes of a cochlear electrode array to induce a current flow in the cochlea at a plurality of temporal locations, measuring one or more electrical properties at one or more locations in the cochlea resulting from the induced current flow at the plurality of different temporal locations and determining whether or not trauma has occurred based on a change between the measured electrical properties from the first temporal location to the second temporal location.

Electrical techniques for biomarker detection in a cochlea

An expert diagnosis system integrated in a hearing prosthesis system is configured to diagnosis, grade, and remediate inner ear crises. In particular, the expert diagnosis system analyzes combinations of in-situ measured inner ear potentials, obtained in response to electrical and/or acoustic stimulation, in order to identify crisis signatures and to correlate those crisis signatures to clinical symptoms of a specific type and cause of an inner ear crises (i.e., automatically diagnosis the inner ear crisis). The expert system is further configured to grade the severity of the identified clinical symptoms and initiate some form of remedial action to address the identified inner ear crisis.
