Increasing tongue strength to reduce dysphagia: what is the potential benefit of a device driven exercise?
Weakness in tongue muscle strength and laryngeal elevation is known to have an adverse impact on swallowing function. Various swallowing exercises are often recommended to improve function of these important structures with the goal of preventing aspiration and improving swallow...Neurological idiopathic disease: a shared journey for NASA and medicine
Whilst Southampton can’t really be described as an extreme environment, experiments carried out in the city have certainly been taken out of this world. Robert Marchbanks discusses one of the associations between Southampton, The International Space Station and tympanic membrane...Speech mapping and the benefits of using in clinical practice
Fitting hearing aids is not simply a case of one size fits all. Nicole da Rocha discusses the benefits of using speech mapping as a verification tool. The verification of hearing aids has become quintessential for best practice. Using either...Multifrequency tympanometry
There are many good reasons to start using multifrequency tympanometry as opposed to a traditional, single 226Hz probe tone. Here, Leigh Martin of Interacoustics discusses the uses and benefits. Tympanometry is a core test in the audiologist’s test battery. In...
Safe distances in the infratemporal fossa
This analysis from China involved 50 enhanced CT datasets to reconstruct the skull, internal carotid artery and the internal jugular vein. The anatomical routes of these vessels were related to the styloid process, height of the pterygoid plates, distance from...
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...
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...
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...
