Abstract

Objectives

Cochlear implantation is a groundbreaking surgical procedure offering significant benefits to individuals with severe hearing impairments. Correct placement of the electrode array within the cochlea is crucial for optimal device functionality and auditory outcomes. Our study describes four cases of electrode misplacement along with the factors causing it and discusses solutions for the same.

Methods

Eight hundred cochlear implant cases were reviewed in three tertiary care centres in India, spanning 2011 to 2023.

Results

Four cases of electrode misplacement requiring reimplantation were identified.

Conclusion

This paper discusses the implications of electrode misplacement, the factors contributing to it and the critical role of multidisciplinary approaches in managing such complications. By addressing these issues, we aim to improve surgical techniques and outcomes in cochlear implant procedures.
