Music training for cochlear implant users
The ability to enjoy music is something that is important to most people and contributes to wellbeing, as well as holding cultural significance. However, the speech signal is generally prioritised for those with cochlear implants (and indeed hearing aids). Improving...
Electrocochleography and cochlear implants programming
Cochlear implants (CIs) often are the only option for people with severe to profound sensorineural hearing loss to be able to hear. Therefore, effective CI programming seems very important, especially in children who are still developing their speech. Using acoustic...
Impedance for different electrode types
Measuring cochlear implant (CI) electrode impedances is common in CI programming appointments to measure the integrity of the implant e.g. whether there are any open or short electrodes. This is because impedance measures the flow of current between intra and...
Moving towards implanting children below 12 months of age
Newborn hearing screening has ensured that deaf infants are identified soon after birth so that habilitation can begin as early as possible. Cochlear implantation is a key component of early intervention for some children, but it is often not performed...
Cochlear implantation in asymmetric hearing loss
Criteria for cochlear implantation (CI) is a constant topic of debate. The UK traditionally had relatively restrictive guidance, although this has been greatly improved by more recent guidance released in 2019. Nevertheless, because of the lack of evidence for cost-effectiveness,...
Robotic insertion of electrode array in cochlear implantation
Cochlear implants (CIs) are commonly used for profound bilateral hearing loss. They have specific national guidance for their insertion, however patients with a substantial residual acoustic hearing are potential CI candidates. Preservation of this residual hearing can be sought with...
The impact of bilateral implantation on language outcomes
An American study retrospectively looked at the language outcomes of 204 children implanted either bilaterally, sequentially or unilaterally. All children received their first implant before the age of three years, and language measures were collected when the children were aged...
Recording of electrode voltages (REVS) to determine extra-cochlear electrodes
Determining whether electrodes are sitting within the cochlea can be difficult as the checks run by the programming software cannot always determine this. In some cases, patients may be unable to give the audiologist detailed feedback which can complicate the...
Hidden disabilities and cochlear implantation under 12 months of age
There has been a global shift to providing children with severe-profound deafness cochlear implants (CIs) before they are 12 months old. Early intervention is critical and one of the overriding factors in successful outcomes for children with CIs. Early implantation...
Dead regions in patients with cochlear implants
The very nature of a dead region (DR) in a cochlea means that they are often found in patients who are eligible for cochlear implants. However, a variety of different hearing configurations are found in those with DRs because of...
X-ray vs. intraoperative testing for determining cochlear implant placement
Most cochlear implant centres confirm electrode position after surgery using X-rays to ensure optimal electrode placement. As well as transorbital view X-rays, this team check placement using impedance measures and neural response telemetry (NRT) performed intraoperatively. The former indicates whether...
How to train adults with single-sided deafness and cochlear implants
Cochlear implantation (CI) in patients with single-sided deafness (SSD) has been carried out in Perth, Australia from 2008. It poses challenges to clinicians and patients who are trying to tune in the poorer ear while still having a normally hearing...
