Clinical Measures in Cochlear Implant Simulations

Abstract:
Cochlear implants have become a standard rehabilitation method for hearing impaired patients. Modern implant systems allow for various recordings modalities of current spread and neural responses. Patient recoded current flow data is used to optimise the conductivity parameters of a realistic 3-dimensional model of the implanted human cochlea. Histological data is implemented obtain correct positioning of neural structures. CT-images are used to implement inter-patient variation. The in this way created model is used to analyse newly developed implant designs and speech coding strategies. The model gives insight in stimulation paradigms and has good correlations with psychophysical and objective measurements.
