[Does the electrodes insertion depth influence speech rehabilitation progress in CI patients?]

Many interdisciplinary teams from difference CI centers are studying speech rehabilitation process of implanted patients. Speech rehabilitation progress depend on many conditions like: duration of deafness, age at implantation, cause of deafness. Rehabilitation of postlingually deafened patients is very short. These subjects return very fast to the world of sounds. By the other side speech rehabilitation of prelingually deafened patients needs much more time (years). There are although well seen differences in language skills acquisition inside these groups. It confirmed, that speech rehabilitation after cochlear implantation could depends on others conditions as well. The aim of this study was electrodes insertion depth evaluation (cochleograms) and its influence on speech rehabilitation progress.
