Summary

Severe to profound hearing loss affects 0,8% of the global population. For these people, a conventional hearing aid often does not provide sufficient benefit. However, these people can benefit from a cochlear implant (CI). A CI needs to be individually programmed (fitted) for each recipient. A fitting "map" is defined as a set of electrical parameters that are individually adapted to a recipient's needs to achieve optimal sound perception. At present, most CI recipients are fitted with a default frequency allocation map that doesn't take individual variability in size and shape of the cochlea into account. In this study, a fitting strategy based on the post-operative CT scan, that will allow the audiologist to set a frequency-band distribution for CI fitting that may be more closely aligned to the natural tonotopic frequency distribution of a normal hearing cochlea, will be evaluated.
