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...

Cochlear implant use in young children

There are clear and well-established links between those identified and fitted with amplification early and good spoken language outcomes, but how much does the time an appropriately fitted hearing instrument is used each day contribute to this? During the first...

Cochlear implants in single sided deafness

Whilst the benefit of a second cochlear implant in people with bilateral deafness is well established, the benefits of implantation for single sided deafness with normal contralateral hearing have been much more modest. The reasons for this are varied, in...

Learning from reimplantation

The Irish implant centre in Dublin undertook a retrospective study of their reimplantation cases to look at what lessons could be learnt. Device failures fall into two classes: hard and soft failures. Hard failures are implant malfunction or altered performance....

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...
