Auditory Brainstem Implantation in Young Children
To purpose of this feasibility study is to demonstrate the safety and efficacy of the Nucleus 24 Multichannel Auditory Brainstem Implant (ABI, Cochlear Corp, Sydney, AUS) in children without the diagnosis of neurofibromatosis type II (NFII) that have either experienced failed cochlear implantation (CI) or have been unable to receive a CI secondary to cochlear or cochlear nerve disorders. These conditions can include: developmental or acquired cochlear nerve deficiency (CND), cochlear aplasia (Michel), post-meningitic cochlear ossification or cochlear malformation.
This study proposes to implant up to 10 young children (<5 yrs. of age) with the Nucleus 24 Multichannel ABI (Sydney, AUS) in an attempt to demonstrate safety of the surgical procedure, tolerance of device stimulation, and the potential for auditory benefit beyond that experienced with their CI. This study will provide the preliminary experience for a larger scale clinical trial.
Aim 1: Demonstrate the safety of ABI surgery in children. Aim 2: Demonstrate the development of sound awareness and improved speech understanding among children implanted with the ABI when compared to their baseline skills. Aim 3: Demonstrate the development of oral language skills following the use of the ABI that were not evident prior to its use.

- Safety and Complications [ Time Frame: 3 years ]Complications and related outcomes will be tracked and recorded. These include bleeding, infection, neural injury, cerebrospinal fluid leakage, brain bleeding or bruising, stroke, death. Also, complications and sequelae related to the device such as non-auditory stimulation and device failure will be tracked.
