Is it time for cone-beam CTs to replace the traditional orthopantomogram in the primary diagnosis of temporomandibular joint disorders?
Cone-beam CT requires a lower dose of radiation compared to the multidetector CT and provides much more detailed information in 3D about the bony structures of the temporomandibular joint (TMJ) when compared to the traditional orthopantomogram (OPG). In this article...
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...
Associated findings in MRI used for detecting acoustic neuroma
Presently, gadolinium enhanced magnetic resonance imaging is the ‘gold standard’ for investigating acoustic neuroma. There are often ‘incidental’ findings that may or may not be significant. In this study of 109 scans, the authors noted an uptake of 0.9% for...
Cochlear implant electrode insertion technique
Atraumatic cochlear implant insertion techniques (so-called ‘soft surgery’) are now standard practice in most centres for all cases (no longer just for attempted hearing preservation cases). This has led to several studies examining cochlear trauma and electrode insertion force. In...Adolescence, drug use and body image
Teenagers are notoriously conscious of how they are perceived by others. Dr Saraiva and colleagues explain how this can lead to problems with substance abuse for both boys and girls, and discuss the different substances they may encounter. Adolescence is...Adult Hearing - Reconfiguring CI services: the ‘new normal’

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...Moving forward for better communication for the Deaf and hard of hearing – Wavefront Centre
Now more than ever, guaranteeing accessibility and inclusion is a vital need for people of all abilities. The Wavefront Centre for Communication Accessibility in Vancouver, BC, is a model on to how to effectively address these issues and serve the...TWJ Fellowship – Toronto 2015: Endoscopic Ear Surgery
The Thomas Wickham Jones (TWJ) Foundation is a charitable trust with the aim of helping patients with deafness overcome their disability. Striving to achieve this goal they provide educational grants to otolaryngologists and other related audiological professionals working within the...Recent changes in vestibular science and assessment
Clinical assessment of the dizzy or imbalanced patient is all about the patient’s history. History, history, history. But what about puzzling cases when we feel we need more information? Sally Rosengren gives us a rundown of the vestibular tests which...Selective upper airway stimulation
Obstructive sleep apnoea (OSA) is one of the most common diseases in industrialised countries and is characterised by an intermittent obstruction of the upper airway during sleep. The standard treatment for OSA is continuous positive airway pressure (CPAP) therapy, which...
