Central auditory changes in SNHL

Robert Harrison discusses some of the most obvious ways in which cochlear hearing loss has central consequences. It is convenient to classify hearing loss according to the most obvious site of lesion, for example, conductive, cochlear, retro-cochlear, or central hearing...

CIs and lymphoma

In this editorial, the authors raise a very serious (albeit hypothetical) question: can the silicon of cochlear implants induce an anaplastic lymphoma akin to breast implants? The case of breast implant-induced large cell anaplastic lymphoma has been highly publicised. Although...

What’s new in the cochlea?

Prof Furness in this article rounds up the steps and leaps being made by the scientific community to develop therapies to support, rejuvenate and / or replace the cochlear structures. David’s electron microscope images of the cochlear structures are world...

Role of imaging in unilateral sensorineural hearing loss

Recent understanding of the significance of unilateral hearing loss in children for language development calls for extensive investigations and early rehabilitation. This retrospective study of 90 children with unilateral hearing loss with high resolution CT scans and MRI revealed that...

Possible correlation of ABR changes with prognosis in sudden sensorineural hearing loss

A sensorineural hearing loss (SNHL) of 30dB or more affecting at least three frequencies and occurring over less than three days is classified as ‘sudden’ SNHL (SSNHL). Treatment is urgently undertaken with systemic and/or intra-tympanic steroids, and ijn some cases...

Neural plasticity and aural rehabilitation

Neural plasticity refers to an ability of the brain and central nervous system to change their structure and function or their reorganisation in response to environmental cues, experience, learning, behaviour, injury and / or diseases and treatments. Neural plasticity is...

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...

Can and should vestibular schwannoma surgery be carried out via the endoscopic transcanal approach?

The extent and scope of endoscopic ear surgery has rapidly progressed in recent years, and this paper, from one of the leading proponents of this technique, reports on the outcomes of a case series of patients who have had total...

The search for pharmacological treatments for hearing loss and tinnitus

Where are we in our search for a hearing restoration grail? Nicola Robas leads us through the map pieces discovered in creating a pharmaceutical answer to hearing loss and tinnitus. Together, hearing loss and tinnitus affect over one in six...

CIs and the elderly

Although cochlear implantation (CI) is thought to be a predominantly paediatric procedure, more and more adults are candidates for cochlear implants. This retrospective study was performed on 80 adults aged above 50 who were implanted for at least nine months....

High definition tractography to identify cranial nerves

It has always been challenging to visualise cranial nerves on traditional imaging as the cranial nerves have a fine structure and complex anatomy. This is especially true regarding the cochlear nerve. In congenitally hearing impaired children, the visualisation of the...

How can we assess children with complex needs?

In the early days of cochlear implantation, children with additional disorders were being excluded as poor candidates whereas today a large number of children with complex needs are being referred for cochlear implant assessment. However, the related problems include difficulties...
