The Next Challenges of Vestibular Implantation in Humans

Area of Science:

• Neuroscience
• Otolaryngology
• Biomedical Engineering

Background:

• Bilateral vestibulopathy causes significant patient burden.
• Current treatments offer limited relief for vestibular dysfunction.
• Vestibular neuroprosthesis development is inspired by cochlear implant technology.

Purpose of the Study:

• To review advancements in vestibular implant development presented at the 2021 ARO Mid-Winter Meeting.
• To discuss challenges and future directions for vestibular neuroprostheses targeting ampullary nerves.

Main Methods:

• Review of symposium presentations and discussions.
• Focus on prototype vestibular implants and combined cochlear-vestibular implants.
• Exploration of electrical stimulation of the vestibular nerve.

Main Results:

• Feasibility of vestibular neuroprosthesis demonstrated in animal and human studies.
• Substantial progress has been made in developing vestibular implants.
• Several research groups are actively investigating prototype devices.

Conclusions:

• Key challenges include optimizing stimulation, surgical procedures, and preserving hearing.
• Regulatory approval and clinical infrastructure development are crucial.
• Overcoming these hurdles will accelerate the clinical application of vestibular implants.
