3D endoscopy in pituitary adenoma surgery

Endoscopic approach for pituitary adenoma surgery is well recognised. There has been recent refinement of 3D endoscopy technology which improves on the depth of vision offered and more compact delivery. This may improve visualisation of the critical structures involved in...

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...

What we need to know about the new frontier of inner ear therapies

This is an interesting and topical review of the emerging biotechnology and pharmaceutical solutions for hearing loss and related conditions such as tinnitus. This paper suggests we are on the cusp of a very large step-change in the way we...

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...

Sound localisation after bilateral cochlear implantation

Limited information is known about the localisation skills of paediatric cochlear implant patients who were good hearing aid users before their hearing deteriorated. As localisation is a skill often associated with good natural hearing, there is a worry that implants...

Talking through technology – keeping up with the mainstream

Augmentative and alternative communication (AAC) system development has often made early use of innovative technology. Touch screens have been a part of this technology for some time. In fact, touch screens were invented in 1965 but it wasn’t until the...

The basis of auditory processing disorder: what can we learn from corticals?

Auditory processing disorder (APD) is a poorly understood, heterogenous and surprisingly common condition. It manifests as a perceptual difficulty in centrally processing auditory information. Diagnosis is usually based on a variety of behavioural tests involving verbal and non-verbal assessments. In...

Variations in obstructive level with increasing depth of sedation in DISE

This study highlights some of the controversies surrounding DISE (Drug Induced Sedation Endoscopy, or otherwise known as sleep nasendoscopy in the UK). On one hand it provides some evidence that the BIS (BiSpectral Index), recordings of patients while they are...
