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...
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...
Electrocochleography and speech-perception in cochlear implant (CI) patients
It is difficult to predict the speech perception outcomes of cochlear implantation. Previous studies showed that total response electrocochleography (ECochG-TR) may explain the variance in CI performance better than biographic, audiometric, and surgical factors combined. The authors’ objectives were to...
Hearing preservation in CI, any predictors?
The electrically evoked compound action potential (eCAP), obtained non-invasively from cochlear implant (CI) recipients, represents a population response of the auditory nerve to electrical stimulation. The eCAP characteristics include threshold (the lower the better), growth of response (the steeper the...A day with Peter Prinsley MP
Our former editor, Ray Clarke, spent a day at Westminster with Peter Prinsley, an ENT surgeon turned Member of Parliament. Peter Prinsley had recently retired from more than 40 years as an NHS Consultant ENT surgeon in Norfolk when he...
Drug eluting stent vs INCS for CRS
A prospective, randomised study from Finland to compare a drug eluting stent (DES) and intranasal corticosteroids (INCS) in 63 patients as assessed by SNOT-22, VAS, endoscopy, CT and rhinometry pre-treatment, at three and six months post treatment. Recruitment was over...Pathways for becoming an audiologist in the USA: Part 2. Academic and licensure requirements today
Part 1 of this topic is available here. Professor Hall reviews current requirements for practising audiology in the USA; audiologists must have a Doctor of Audiology degree from an accredited university programme and a licence in the state where they...
Are they just ignoring you?
The clarity of hearing in background noise, which is influenced by the signal-to-noise ratio, has been a much-debated topic over many years from various angles. This study looks at anaesthetised cats and, as cats are not commonly known for their...The evolving role of OAEs in newborn hearing screening
An admission on emissions from James Hall! OAEs hold an established place in the screening of infants; Professor Hall introduces how OAEs established this position and the advances keeping the test relevant to today’s infant screening battery. Introduction Truthfully, when...Addressing the hearing needs of people with dementia
Dr Dawes provides a comprehensive overview of hearing needs of persons with dementia coupled with recommended guidelines for hearing-related considerations when assessing and intervening with persons with dementia. With ageing populations, we face a global dementia challenge. Rates of both...
