Hearing loss and cognition: something to think about

Irace, Chern and Golub propose causal and non-causal mechanisms for the links between hearing loss and dementia, concluding with a discussion of several proactive measures available to help preserve neurocognitive health in older adults with hearing loss. What is age-related...

New MRI technique assesses treatment response in skull base osteomyelitis

This paper describes another useful imaging technique to monitor Necrotising Otitis Externa (NOE). Echoplanar diffusion weighted magnetic resonance (DW MR) shows high signal on the ‘ADC map’ with active disease and this reduces in signal intensity as symptoms improve. This...

Consider PCR testing in culture negative necrotising otitis externa

Necrotising otitis externa (NOE) often does not yield identification of a causative organism to treat although in 90% of cases it is a member of the pseudomonas species. The incidence of fungal NOE is not to be forgotten and this...

The missing link: how migraine neurophysiology amplifies tinnitus

This article discusses an emerging hypothesis linking bothersome tinnitus with migraine-related sensory processing dysfunction. When evaluating patients with tinnitus, a range of contrasting experiences are noted, from mild, non-bothersome symptoms to those associated with significant distress – broadly corresponding to...

How has management and outcomes of necrotising otitis externa changed over the past decade?

Necrotising otitis externa (NOE) remains a challenging condition for ENT departments, particularly with the increased prevalence of diabetes mellitus (DM) in the general population. There is no international consensus on treatment, although many institutions now have local guidelines drawn up...

A diagnosis-based scoring system to predict outcomes in necrotising otitis externa

Patients admitted with necrotising otitis externa have increased six-fold in the last 10 years. The prognosis is variable and dependent on co-existing morbidities. Charlston Comorbidity Index (CCI) is a weighted comorbidity scoring method, based on the presence or absence of...

Management of necrotising otitis externa

Although uncommon, necrotising (previously malignant) otitis externa (nOE) can be very aggressive, particularly if not managed appropriately. In this study the authors perform a retrospective review of 25 patients admitted with nOE over a four year period at a tertiary...

Patient experience of necrotising otitis externa

Necrotising otitis externa is increasing in incidence in the UK and becoming a rising burden to patients and health services. Despite a growing body of literature on this condition, we know very little about patient experience of necrotising otitis externa....

Is clinical HIT as good as vHIT in the emergency room?

Establishing the cause of acute vestibular syndrome (AVS) is critical in the first few hours of presentation in the emergency department. The first question to ask is, “is it due to a peripheral vestibular pathology or a stroke?” This is...

Indication and timing of electrodiagnostic tests in facial palsy

This excellent review describes the benefits and limitations of electrodiagnostic testing for patients with facial paralysis. Tests such as Schirmer, stapedial reflex and electrogustometry have been largely replaced by neurophysiologic tests like nerve excitability test (NET), electroneuronography (ENoG), surface electromyography...

What’s hidden in hidden hearing loss?

In order to truly understand the many key aspects of acquired sensorineural hearing loss, the role of cochlear synaptopathy or ‘hidden hearing loss’ must be considered. Dan Guo and Sharon Kujawa review and summarise what we know to date, including...

Botulinum toxin injection for bilateral recurrent laryngeal nerve paralysis

All traditional surgical treatments for bilateral recurrent laryngeal nerve (RLN) paralysis are essentially a balance between maximising airway patency and ensuring adequate phonation / airway protection. This paper highlights the potential role of botulinum toxin (Botox) injection into the cricothyroid...
