[Our surgical experience of 20 extracochlear implantations on the oval window with transcutaneous approach]

While multichannel implants can produce far better results than single-channel implants, the results of a multichannel implantation are impossible to predict accurately preoperatively. Single-channel implants, which produce average and constant results, still have a major merit in that their cost is much lower. Since extracochlear implantation with transcutaneous approach is innocuous, we have been promoting this type of implantation as a temporary procedure until much more effective systems are found in the future, or as a definitive implantation.
