The study aimed to assess whether insertion length and the number of active channels are preserved after cochlear implant reimplantation. A retrospective review of 170 consecutive multichannel cochlear implant cases, focusing on Nucleus users reimplanted in the same ear, was performed. Seventeen devices required replacement; most patients maintained insertion length and channel count, but a few experienced substantial decreases, and overall the group showed a small but statistically significant decline, indicating that while reimplantation is feasible, the initial surgery offers the optimal outcome.
The objective of this study was to determine whether insertion length and number of active channels remained the same after reimplantation of a cochlear implant. A retrospective case review of 170 consecutively implanted multichannedl cochlear implants was conducted. Seventeen of these devices had to be replaced. Data were analyzed for the Nucleus cochlear implant users who were reimplanted in the same ear. For most subjects, insertion length and number of channels remained unchanged, but a few subjects experienced substantial decreases. When the whole group was considered, a small but statistically significant drop was noted for both parameters. In conclusion, although reimplantation is technically possible, the first procedure provides the optimal surgical environment.
