Peripheral nerve stimulation for chronic refractory pain

Peripheral nerve stimulation (PNS) plays an important role in treating chronic refractory pain syndromes that manifest in limited distributions and overlap with areas of neurologic innervation. The process is generally thought to capitalise on the inhibition and activation of pain-related...

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...

Advances in auditory implants

This article provides an overview of auditory implants. Implanted auditory devices may be classified into bone conduction implants (BCI) and active middle ear implants (AMEI) that stimulate cochlear hair cells, and cochlear implants (CI) that stimulate neural structures. CIs bypass...

How rare is vocal fold paralysis after spinal and epidural anaesthesia – should we be more concerned?

The authors present an unusual case of right vocal fold paralysis. Their patient was a 38-year-old woman who experienced new onset dysphonia following neuraxial anaesthesia (NA) for a caesarean section. Flexible nasendoscopy showed a right VFP with fixation in the...

Microgravity: an extreme environment for otolith organs

Motion sickness in a car can be upsetting for all involved. Transferring this concept into a tiny cabin bound for space could have devastating consequences. Are the processes involved in ‘space motion sickness’ the same as motion sickness? How do...

Update on the development of an implantable vestibular prosthesis

Cochlear implants have revolutionised the management of profound hearing loss. Might vestibular implants be the future for the treatment of bilateral vestibular failure? James Johnston and Neil Donnelly explore. The vestibular system is highly complex, integrating visual, labyrinthine and proprioceptive...

Hidden hearing loss in humans

Awareness of cochlear synaptopathy (‘hidden hearing loss’) is growing. Chris Plack gives us an introduction to the condition, defining it and reviewing recent research in humans and animals with respect to noise exposure. The main cause of hearing loss is...

Balance and vestibular disorders in children

Discover the world of paediatric vestibular assessment and management from the team at Alder Hey Children’s Hospital, which is revolutionising services in this field. Dizziness and balance problems generate significant morbidity in children of all age groups. Vestibular disorders are...

An app to help display hearing results

Vestibular neuronitis (VN) is a common condition that we treat. Despite this, many of us lack the in-depth knowledge and scientific reasons for doing what we do. Granted, the evidence is lacking in some areas but this paper is worth...

The electromagnetic larynx

Current treatment options for a bilateral vocal cord palsy (tracheostomy, posterior cordotomy, arytenoidectomy) are suboptimal, with a focus primarily on a static means of airway restoration at the expense of voice production and potentially swallow safety. This paper reports on...

To endo or to micro, that is the question: the musculoskeletal paradigm

Endoscopic ear surgery is a newer concept compared with the microscopic one. Both could lead to musculoskeletal pain due to the long static posture of surgeons during otologic procedures. The authors conducted a study on eight otolaryngologists, four attendings and...

The tip in rhinoplasty

Getting the tip right (both its position and its shape) is vital in rhinoplasty. George Marcells eloquently gives us his perspective on how to get it right. “Many surgeons overly concentrate on the profile at the expense of the frontal...
