Summary
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.
