Summary
This summary is machine-generated.

Cochlear implant (CI) reimplantation is a safe and effective procedure for patients experiencing device failure. Hearing outcomes following reimplantation are comparable to initial implantation, ensuring continued auditory function.

Area of Science:

  • Otolaryngology
  • Biomedical Engineering
  • Neurosurgery

Background:

  • Multichannel cochlear implants (CI) can fail, necessitating reimplantation in a subset of recipients.
  • Understanding the reasons for failure and outcomes of reimplantation is crucial for managing CI patients.

Purpose of the Study:

  • To describe the causes of multichannel cochlear implant (CI) failure.
  • To detail the surgical technique for CI reimplantation.
  • To evaluate hearing outcomes after CI reimplantation.

Main Methods:

  • Retrospective analysis of a consecutive clinical series of 16 patients undergoing CI reimplantation.
  • Comparison of outcomes between initial implantation and reimplantation, including electrode insertion, programming, and audiometric results.
  • Documentation of failure causes and surgical findings during reimplantation.

Main Results:

  • No surgical complications were observed following CI reimplantation.
  • Device failure was the primary reason for reimplantation, occurring at a mean of 22.4 months post-initial surgery.
  • Post-reimplantation hearing and speech recognition scores were comparable to pre-failure levels.

Conclusions:

  • Cochlear implant (CI) reimplantation is a safe and effective surgical procedure.
  • Reimplantation successfully restores or maintains auditory function in patients with device failure.
