Current treatment options for bilateral profoundly deaf children, diagnosed with inner ear anatomical abnormalities are limited, and in the case of absent cochleas, non-existent. An auditory brainstem implant (ABI) places an electrode close to the auditory nucleus in the brainstem. Children aged 2 - 5 who are not candidates for a cochlear implant, or who did not demonstrate benefit from a cochlear implant, will be implanted with an ABI and followed for 1 year for safety and a total of 3 years for preliminary efficacy. This is a feasibility study to determine the safety of the ABI.

Condition Intervention Phase
Bilateral Cochlear Aplasia
Bilateral Cochlear Nerve Deficiency
Bilateral Cochlear Ossification Secondary to Meningitis
Device: Auditory brainstem implant
Phase 1

Study Type: Interventional
Study Design: Intervention Model: Single Group Assignment
Masking: Open Label
Primary Purpose: Treatment
Official Title: A Feasibility Study of the Placement, Use, and Safety of the Nucleus 24 Auditory Brainstem Implant in Non-Neurofibromatosis Type 2 (NF2) Pediatric Patients

Further study details as provided by House Research Institute:

Primary Outcome Measures:
  • Number of Serious Adverse Events [ Time Frame: 12-month post-activation ]
    Count of the number of expected serious adverse events must not exceed that known to occur in pediatric retrosigmoid craniotomy and Count of the number of unexpected serious adverse events must not exceed 2 in the first 5 children.

Secondary Outcome Measures:
  • Access to sound at a level (dB) and within the frequency range (500-4000 Hz), known to be associated with speech [ Time Frame: 3 years post-activation ]
    ability to detect sounds
