Outcome Measures

Primary Outcomes (2)

  • Change in Hearing In Noise Test Score in Quiet (HINT-Q) From Baseline to 6 Months in English-speaking Participants.

    To assess the clinical efficiency, speech perception performance using the HINT sentences was measured in quiet at 6 months pos-activation in English speaking participants. Primary clinical efficiency outcome is defined as the change in HINT scores from baseline to 6 months post-activation. Recorded HINT sentences lists were presented to the participant at 60 dB SPL (sound pressure level) pre-operatively in the best aided hearing conditions and at 6 months in the implanted ear after Neuro Zti implant activation. The post-activation assessment was performed in the implanted ear alone with masked controlateral ear. Resultant score is a percentage of words correctly repeated. Possible scores are range from 0% to 100% words correctly repeated. Change = (6 Months score - Baseline score). A score greater or equal to 10% was considered clinically significant improvement.

    pre-operative, 6 Months

  • Major Related Adverse Event (AE)

    Adverse event (AE) is defined as any undesired change from the participant's baseline condition symptom or clinically relevant symptom or disease, regardless of its cause. AEs include complications that are related to the device or clinical procedure, as well as unrelated AE that are not related to the device or the trial procedure. AEs were classified as Major if they corresponded to any of the following criteria: * life-threatening conditions (e.g. meningitis) * require hospitalization * result in permanent disability or damage (e.g. facial nerve paresis) * require revision surgery with or without explantation or re-implantation (e.g. device failure, flap necrosis) * medical events that could not be alleviated by electrode deactivation (e.g. tinnitus, facial nerve stimulation, pain) The co-primary safety endpoint is the major related adverse events rate during the surgery and over the post-surgical period from activation to 12 months post-activation.

    3, 6 and 12 months

  • Hearing In Noise Test Score in Quiet (HINT-Q) Pre-operatively, at 3-, 6- and 12-Months on English-speaking Participants

  • Hearing In Noise Test Score in Noise (HINT-N) Pre-operatively, at 3-, 6- and 12-Months on English-speaking Participants

Eligibility Criteria

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

You may qualify if:

  • Adults, eighteen (18) years of age or older.
  • Bilateral severe-to-profound sensorineural hearing loss, defined by pure-tone average (PTA) ≥70 dB HL (Hearing Level) at 500, 1000 and 2000 Hz on both ears.
  • HINT sentences recognition scores in quiet ≤ 50% correct, in the best-aided listening condition.
  • Post-lingual onset of deafness.
  • Primary implantation (no re-implantation).
  • Up-to-date pneumococcal vaccine.

You may not qualify if:

  • Medical conditions that contraindicate undergoing cochlear implant surgery (middle ear diseases i.e. AOM/CSOM (Acute Otitis Media/Chronic Suppurative Otitis Media) , lesions of auditory nerve, pathologies of central auditory pathway, otosclerosis; cochlear malformation i.e. Mondini malformation, cochlear ossification, large vestibular aqueduct).
  • Unrealistic expectations regarding the possible benefits, risks, and limitations that are inherent to the surgical procedure and medical device.
  • Unwillingness or inability of the candidate to comply with all investigational requirements.
