Abstract

There are numerous advantages for patients who can add residual acoustic hearing to the electric stimulation of a cochlear implant. When cochlear implantation was first becoming accepted, patients were typically profoundly deaf in both ears, so any possible advantages of also using acoustic hearing were non-existent. However, as time progressed and the range of patients considered for implantation was expanded to include those with more and more residual hearing, this remaining acoustic hearing became a factor to consider. The residual acoustic hearing was at first most often located in the non-implanted ear, especially since the trend has been to place the implant in the poorer ear if there was any aidable hearing. In recent years, residual acoustic hearing has been preserved even in the implanted ear, whereby acoustic and electric hearing are combined in the same ear. It turns out that the acoustic hearing that remains in either ear after cochlear implantation can still contribute to overall performance in some very significant ways, including cases where, by itself, the acoustic hearing produces only minimal or no word recognition.
