Auditory Performances With Different Stimulation Depths in Cochlear Implanted Subjects Using a Fine Structure Strategy
Study of Musical Perception and Post-operative Auditory Performance as a Function of the Depth of Stimulation in Subjects Implanted With a MED-EL Cochlear Implant and Using a FineHearing Strategy Single-center Randomized Cross-over Study
MED-EL Elektromedizinische Geräte GesmbH
32 participants
Jul 10, 2021
INTERVENTIONAL
Conditions
Summary
Main objective: Investigate on new cochlear implanted patients whether the FineHearing strategy of the MED-EL cochlear implant gives better results on musical perception if the depth of stimulation (stimulation or not of the apical areas) is greater. Secondary objectives: Evaluate the effect of stimulation depth on vocal audiometric results, results of differential frequency threshold test and on qualitative sound perception.
Eligibility
Inclusion Criteria4

- Patient who fulfils the criteria for cochlear implantation
- Patient with a postoperative insertion angle of the apical electrode \> 450°
- Patient with 12 active electrodes on the day of activation.
Exclusion Criteria1
- Retro-cochlear pathology: auditory neuropathy, vestibular schwannoma
