Background: A vestibular implant can partially restore vestibular function by providing motion information through implanted electrodes. During vestibular implantation, various obstructions of the semicircular canals, such as protein deposits, fibrosis, and ossification, can be encountered. The objective was to explore the relationship between preoperative imaging and intraoperative findings of semicircular canal obstruction and to develop surgical strategies for dealing with obstructions of the semicircular canal(s) in patients eligible for vestibular implantation.

Article Synopsis
  • The study aimed to assess the stability of electrode positions in vestibular implants (VI) over a one-year period with seven patients.
  • Fourteen out of 18 electrodes showed no significant displacement after surgery, indicating good stability, while some displacement occurred in four electrodes, possibly due to measurement error.
  • The results suggest that the surgical techniques used effectively stabilize the electrodes, preventing migration over time.

Introduction: The vestibular implant is a neuroprosthesis which offers a potential treatment approach for patients suffering from vestibulopathy. Investigating the influence of electrical stimulation parameters is essential to improve the vestibular implant response. Optimization of the response focuses on the electrically evoked vestibulo-ocular reflex.
