- Abstract
This case study details the evaluation, explantation, and subsequent reimplantation of a cochlear implant (CI) recipient with an unusually deep electrode array insertion. Although the positive value of sufficiently deep insertion and the effect of insertion variability have been researched, there are few data available that illustrate the detrimental effects on speech recognition when deep insertion corrupts optimal use of the CI. This unique case report challenges the assumption that deeper insertion will result in improved speech understanding and demonstrates the importance of fully evaluating recipients' complaints and recognizing the impact of frequency-to-place mismatch.
