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...

Semicircular canal dehiscence and cochlear implantation

Semicircular canal dehiscence (SCD) is thought to occur in 3% of the population, it is mostly asymptomatic, but patients may present with sound-induced vestibular symptoms, low-frequency conductive hearing loss, autophony, hyperacusis and aural fulness. With the increasing utilisation of cochlear...

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...

Can we centralise cochlear implant surgery and keep most appointments close to home?

The NHS Five Year Forward View promoted seeing patients closer to home in order to provide better care, cut down on missed appointments and reduce costs. This encouraged the development of ‘hub and spoke’ models of care, but this model...

Quality of life after cochlear implantation in the older population

Cochlear implants (CI) have been increasingly adopted in older adults with severe to profound hearing loss as a result of the growing and ageing world population. There is much interest in the cost-effectiveness and quality of life in CI users....

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...

Satisfaction levels in elderly patients with cochlear implants

Hearing rehabilitation in the elderly is of utmost importance as it is associated with depression and dementia in this age group. Cochlear implantation is indicated for hearing-impaired individuals who do not derive adequate benefit from conventional hearing aids. In this...

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...
