Combined Electric and Acoustic Stimulation: Successful Treatment Option for Partial Deafness

Partial deafness cochlear implantation (PDCI) and electric-acoustic stimulation (EAS).

The purposes of this paper are to (1) review briefly the experience to date with combined EAS for patients with some residual, low-frequency hearing; and (2) describe the further results that have been obtained with this combination for patients with higher levels of residual hearing at low frequencies, termed 'PDCI'. In broad terms, PDCI and combined EAS have produced large improvements in the...

Physiological Mechanisms in Combined Electric-Acoustic Stimulation.

OBJECTIVE Electrical stimulation is normally performed on ears that have no hearing function, i.e., lack functional hair cells. The properties of electrically-evoked responses in these cochleae were investigated in several previous studies. Recent clinical developments have introduced cochlear implantation (CI) in residually-hearing ears to improve speech understanding in noise. The present stu...

Mandarin Speech Perception in Combined Electric and Acoustic Stimulation

For deaf individuals with residual low-frequency acoustic hearing, combined use of a cochlear implant (CI) and hearing aid (HA) typically provides better speech understanding than with either device alone. Because of coarse spectral resolution, CIs do not provide fundamental frequency (F0) information that contributes to understanding of tonal languages such as Mandarin Chinese. The HA can prov...

Electric acoustic stimulation in children.

BACKGROUND/AIMS The combined electric acoustic stimulation (EAS) of one ear is a topic that has received considerable attention over the last 10 years, the technique having originally been introduced by Prof. Christoph A. von Ilberg for so-called borderline adult cochlear implant (CI) candidates. Its development has followed several parallel strands, including the modification of existing surgi...
