To scan or not to scan?

This comprehensive review article seeks to establish how useful is MRI in the evaluation of patients with a history of smell loss or distortion. Interestingly, while some studies found the imaging unhelpful, one paper described found a 25% rate of...

Reliability of Koos classification

Vestibular schwannoma (VS) tumour size has been considered the primary determinant of hearing outcomes and facial nerve function according to several published studies. Varying methods are used to estimate the size and volume of the VS with very little consensus...

High definition tractography to identify cranial nerves

It has always been challenging to visualise cranial nerves on traditional imaging as the cranial nerves have a fine structure and complex anatomy. This is especially true regarding the cochlear nerve. In congenitally hearing impaired children, the visualisation of the...

What to do with incidental findings on FDG PET/CT?

18F-fluoro-deoxy-glucose positron emission tomography/computed tomography (FDG PET/CT) is commonly used in head and neck cancer staging. This investigation frequently identifies incidental findings unrelated to the index head and neck cancer. To assess the nature of these incidental findings, notes of...

Should we be doing earlier MRIs in sudden sensorineural hearing loss?

There is recognised variation between ENT departments in exact imaging protocols for the workup of idiopathic sudden sensorineural hearing loss (ISSNHL) but a routine MRI to exclude retrocochlear pathology is standard, usually following immediate treatment with oral +/- intratympanic steroids....

Do we need contrast MRI when screening for vestibular schwannoma?

Gadolinium contrast enhanced T1-weighted (gT1w) MRI images of the internal acoustic meati have long been considered the gold standard in the diagnosis of vestibular schwannoma (VS). However, the addition of contrast to the MRI examination increases the cost and time...

Diagnostic criteria for superior semicircular canal dehiscence syndrome

The latest Bárány Society’s consensus document on diagnostic criteria for vestibular disorders is one for superior semicircular canal dehiscence syndrome (SCDS). There are three major categories: (A) Symptoms consistent with a third mobile labyrinthine window; (B) Physiologic tests – clinical...

Cochlear implants: recipient stories

The most powerful evidence for the remarkable achievements made with cochlear implants over 40 years comes from the life-changing, personal stories of those who have benefited from the technology. James Rylance I first noticed a problem with hearing when I...

Innovation in medical product technologies

There is a point in all innovation projects where the clinician has exhausted their knowledge and needs expert help to create a prototype. Mark Prince, Design Engineer, discusses this phase of the project and how engineers’ analytical thinking brings a...

A funny thing happened on the way to a conference – and other stories

This series of stories is dedicated to those of you with whom some of these moments were shared (or endured) and, above all, to my amazing and long-suffering husband, David Howard. Most of you know him as an exceptional head...

Intraoperative MRI use during pituitary tumour resection

This article provides an overview of intraoperative MRI (iMRI) use in transphenoidal surgery (TSS) for pituitary tumours. Traditionally imaging of the surgical field during surgery involves intraoperative fluoroscopic imaging or neuronavigation which help to avoid injury to critical structures but...

CEORL-HNS 2024

Held from June 15 to 19 at the Dublin Convention Centre, this was an unmissable event for ENT surgeons and allied health professionals across the world. Hosted by Professor John Russell, the President of the Confederation, the event brought together...
