Auditory brainstem implants (ABI) offer hearing sensations for Neurofibromatosis type 2 (NF2) patients. Recent advancements show ABIs can provide excellent speech recognition, enabling even telephone conversations for those deafened by NF2-related surgery.

Area of Science:

  • Neuroscience
  • Otolaryngology
  • Biomedical Engineering

Background:

  • Neurofibromatosis type 2 (NF2) commonly causes bilateral vestibular schwannomas, leading to hearing loss after surgical removal.
  • The auditory brainstem implant (ABI) was developed to restore hearing by stimulating the cochlear nucleus in deafened NF2 patients.

Purpose of the Study:

  • To review recent developments and improving outcomes of the auditory brainstem implant (ABI).
  • To discuss potential causes for the variability in ABI outcomes.

Main Methods:

  • Review of historical and recent outcomes data for ABI implantation.
  • Analysis of ABI performance in NF2 patients and other populations.

Main Results:

  • Early ABIs provided modest hearing sensations; recent applications show high speech recognition, even in NF2 patients.

  • ABIs demonstrate functional hearing benefits, including environmental sound awareness and lipreading enhancement.
  • Excellent speech recognition, including conversational telephone use, is now achievable with ABIs in some NF2 patients.

    • Conclusions:

    • Auditory brainstem implants (ABIs) effectively recreate hearing sensations by activating cochlear nucleus neurons.
    • Most NF2 patients benefit functionally from ABIs, with some achieving excellent speech recognition.
    • Further research is needed to fully understand factors contributing to improved ABI performance in NF2 patients.
