Outcome Measures

Primary Outcomes (2)

  • Speech recognition score (word score)

    The primary efficacy objective is to demonstrate that mean monosyllabic word recognition score (Minimum Score 0 percent and maximum score 100 percent wheras 0 percent is worse and 100 is better) with the Ultra implants used in combination with a sound processor programmed with the latest fitting software is at least 20 percent better than the mean monosyllabic word score at baseline with conventional amplification in the same ear.

    6 months

  • Analysis of participants with device failure

    A maximum of one device failure that require device replacement during the first six months following device activation (activation approximately one to eight weeks after surgery).

    6 months

Secondary Outcomes (1)

  • Analysis of Speech reception threshold

    6 months

Other Outcomes (6)

  • Device fitting data

    6 months

  • Device verification data

    6 months

  • Professional feedback from the audiologist using the latest fitting software to program the latest processor

    6 months

  • +3 more other outcomes

Interventions

patients receive a cochlear implantation within clinical routine

Eligibility Criteria

Age18 Years+
Sexall
Age GroupsAdult (18-64), Older Adult (65+)
Sampling MethodNon-Probability Sample
Study Population

30 adult subjects with valid and useable data

You may qualify if:

  • No previous experience with any auditory implant
  • years of age or older
  • Postlingual onset of severe hearing loss (≥ 4 years of age)
  • Limited benefit from appropriately fitted hearing aids, defined as scoring 60% or less in Freiburger Monosyllabic word test
  • German language proficiency
  • Willingness to participate in all scheduled procedures outlined in the protocol

You may not qualify if:

  • Cochlear malformation or obstruction that would preclude full insertion of electrode array.
  • Presence of additional disabilities that would prevent or interfere with participation in the required study procedures
  • Medical or psychological conditions that contraindicate surgery or impact the ability to manage an implanted device or the study related procedures
  • Evidence of central auditory lesion or compromised auditory nerve
  • Pregnancy at time of surgery.
