Percutaneous pedestals in cochlear implantation

Abstract

Percutaneous pedestals have been integral to the development of cochlear implants since 1969. By enabling direct electrical access to implanted electrodes or other devices, they allow optimization of control of stimulation strategies. Similarly, technology not validated for implantable use can be safely tested. These advantages have facilitated the development of cochlear implants and also resulted in their inclusion in trials investigating electronic implants developed for other organs. Surgery is straightforward, but post-operative care, in particular, skin-care is crucial to ensure complications are minimized. This review discusses the history of percutaneous pedestal use in cochlear implants and other electronic devices. Surgical technique, aftercare, and complications of surgery are discussed along with possibilities for future development.
