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...

Maturation of BC attenuation

The aim of this study was to clarify the reason for differences between bone-conduction hearing in adults and infants. The authors investigated how the sound pressure level in the ear canal changes depending on the bone-conduction transducer placement. By using...

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...

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...

Basic Fundamentals in Hearing Science

The preface to this textbook explains that its inspiration came from an identified need to replace a previously discontinued hearing science textbook authored by Durrant and Lovrinic in 1995. This was an excellent resource that I used throughout my own...

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...

Head and neck radiation and the brain

An increasing number of patients with head and neck squamous cell carcinoma and other lesions are treated with high dose radiotherapy. An increase in survival rates is being reported along with a younger patient demographic. The long-term effects of treatment...

Botox application for drooling shrinks salivary glands

The large majority of sialorrhoea (drooling) in paediatric patients is managed conservatively. However in severe cases, often where there is associated developmental delay or a motor disorder, medical and surgical techniques can be used to decrease salivary flow. Botulinum toxin...

Targeted focal parathyroidectomy

Leanne Hamilton and Louise Clark describe their technique for helping to localise parathyoid adenomas. Surgically this can be difficult, so careful preoperative evaluation using imaging as described can help minimise difficulties intraoperatively when identifying the parathyroid adenoma. Preoperative imaging has...

What’s new in electrophysiology?

Steve Bell is a lecturer at the University of Southampton and a member of the British Society of Audiology’s (BSA) Special Interest Group in Electrophysiology. Given the current surge in interest in electrophysiology, both in rehabilitation and diagnostic arenas, Steve...

eSRTs versus eCAP: Which is better?

Electrically evoked compound action potentials (eCAP) and electrically evoked stapedius reflex threshold (eSRT) techniques were compared to establish how well the two techniques correlated and which yielded quicker results in a group of paediatric cochlear implant (CI) users. This team...
