ABSTRACT
Background:
In the literature cochlear reimplantation is described as a possible surgical procedure and the change from a single to a multichannel device is associated with audiological improvement.

Material and Methods:
A 47 year old male caucasian patient presented after cochlear implantation 21 years ago. Lacking any benefit from the old single-channel implant over the last few years, the patient no longer used the device. The old cochlear implant was changed for a modern multichannel unit.

Results:
The patient showed a great improvement in hearing threshold and his quality of life with the new device.

Conclusions:
This case justifies the reimplantation of patients who have been implanted more than 20 years ago.
