This Post-Market Clinical Follow-up (PMCF) investigation aims to further collect evidence on safety and performance of the Mi2000 TICI. This PMCF investigation will prospectively collect clinical data from the use of the Mi2000 TICI and related devices.
This PMCF investigation is performed on a cochlear implant system newly introduced to the market, which was previously studied in two pre-market clinical investigations. The purpose of the current clinical investigation is to collect further evidence by collecting additional clinical data on the use of the Mi2000 TICI.
796 studies on the registry are indexed under Hearing Loss; 193 are open to participants now.
This study's planned enrollment of 22 is below the median of 44 across 561 interventional studies indexed under Hearing Loss.

Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.
You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.

Participants in this clinical investigation will be implanted with an Mi2000 TICI totally cochlear implant
Device: Cochlear Implantation
Participants in this clinical investigation will receive a totally implantable cochlear implant.
Word Test in Quiet
Word recognition in quiet, on a scale from 0 to 100% correct, higher scores indicate better outcomes
Time frame: Pre-op to 6 months after first fitting
Sentence Test in Noise
Oldenburg Matrix Test, results measured in dB signal-to-noise ratio (SNR) with a range of +30 to -10 dB SNR, lower values indicating better outcomes
Time frame: Pre-op to 6 months after first fitting
Health Utility Index Mark 3 (HUI3)
Health utility scale: 1.00: Perfect health. 0.00: Death. Negative values: States worse than death.
Time frame: Pre-op to 6 months after first fitting
Nijmegen Cochlear Implant Questionnaire (NCIQ)
Disease specific Quality of Life, overall score is on a scale from 0 to 100, higher numbers indicating better outcomes

Hearing Implant Sound Quality Index (HISQUI)
Sound quality score ranging from 19 (very poor sound quality) to 133 (very good sound quality)
Time frame: through study completion, an average of 12 months after first fitting
Tinnitus Functional Index (TFI)
Tinnitus questionnaire measures the severity and negative impact of tinnitus on a 0 (Not a Problem / Slight Tinnitus) to 100 (Very Big Problem / Very Severe Tinnitus) scale
Time frame: through study completion, an average of 12 months after first fitting
Audiogram
Pure-tone air-conduction hearing thresholds will be measured in each ear. The threshold is the lowest sound level, in decibels hearing level (dB HL), at which the participant responds. The outcome is the threshold at each frequency. Higher thresholds mean poorer hearing; lower thresholds better hearing.
Time frame: through study completion, an average of 12 months after first fitting
