Percutaneous pedestal in cochlear implantation. Direct electrical connection between an external sound-processing device and intracochlear electrodes is accomplished via a percutaneous pedestal. Patient pedestal complaints and experience have been recorded. Pedestal problems have been classified into six classes, with class 0 indicating no problems and the severity of problem increasing in classes 1 through 4. Class 5 indicates pedestal trauma. No class 5 problems were encountered. At 48 months of experience, 53% of patients were class 0 and 26% were class 1. The pedestal experience is detailed in the paper. The percutaneous pedestal has been found to be a well-tolerated, efficient system for information transfer in cochlear implant patients.
