NCT06459765

Brief Summary

The goal of this clinical trial is to test the Mi2000 Totally Implantable Cochlear Implant in a population of candidates for a cochlear implant. The main question it aims to answer is, whether the device is able to improve speech perception compared to the pre-operative score. Participants will undergo cochlear implantation and fitting, and will be asked to perform the following tests pre- and post-operatively:

  • Word test in quiet
  • Sentence test in noise
  • Audiograms
  • Health Utilities Index 2 and 3 (HUI2\&3), a generic quality-of-life questionnaire
  • Nijmengen Cochlear Implant Questionnaire (NCIQ), a disease specific quality-of life questionnaire
  • Speech, Spatial and Qualities of Hearing Scale (SSQ12), a disease specific questionnaire
  • Hearing Implant Sound Quality Index (HISQUI19), a sound quality questionnaire

Eligibility Criteria

Age18 Years+
Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • Minimum age of eighteen (18) years at time of enrolment
  • Bilateral sensorineural hearing loss with no or limited benefit from a hearing aid (\>70 dB HL PTA4)
  • Post-lingual onset of deafness
  • No or limited benefit from hearing aids for less than 10 years and an expected benefit from cochlear implantation
  • A maximum score of 50% on a word test in the language of the test centre in the ear to be implanted in the best aided condition
  • Fluency in the test language with excellent proficiency, as appropriate to perform speech testing
  • Functional auditory nerve
  • General health condition, psychological and emotional condition deemed compatible with the treatment and tests performed in this study
  • Pre-operative assessment according to the local professional standards
  • Candidate is highly motivated and has realistic expectations about the expected benefit of the implant and shall understand the importance of returning to the implant centre for regular speech processor programming, assessment sessions and training
  • Realistic expectations, as deemed appropriate by the implanting surgeon/implant board
  • Evidence of up-to-date vaccinations against meningitis, as per recommendations by the applicable national body
  • Signed and dated informed consent before the start of any study-specific procedure

You may not qualify if:

  • Previously having received an implant on the location chosen for placing the cochlear implant
  • Having received a hearing implant from another manufacturer than MED-EL on the contralateral ear
  • Pre-existing condition known to necessitate MRI scans after implantation of the Mi2000 TICI
  • Women being pregnant or nursing
  • Women of childbearing age not reporting to use effective contraception
  • The individual is known to be intolerant of the materials used in the implant or other required accessories including medical grade silicone, parylene C, titanium, platinum iridium, platinum, stainless chromate steel, thermoplastic elastomere (TPE-S), thermoplastic elastomere (SEBS), mixture of polycarbonate and acrylonitrile-butadiene-styrol polymer (PC/ABS), polyamide, liquid crystal polymer, silicone and polyurethane-coated silicone rubber)
  • Absence of cochlear development
  • The cause of deafness is non-functionality of the auditory nerve and/or the upper auditory pathway
  • Medical contra-indications to middle ear and/or inner ear surgery, and/or anaesthesia
  • External or middle ear infections are present
  • The tympanic membrane is perforated in the ear to be implanted
  • Anatomic abnormalities are present that would prevent appropriate placement of the stimulator housing in the bone of the skull, or prevent placement of the chosen electrode array into the cochlea (including ossification of the cochlea)
  • The psychological status of the individual is unstable
  • The individual has unrealistic expectations
  • Acute cholesteatoma
  • +8 more criteria
