Effects of blast and acoustic trauma: assessment of hearing status on war veterans

Introduction Acoustical conditions of the military are often dangerous and there is a real risk of blast trauma and acoustic trauma [1, 2]. Levels of military noises maybe reach up to 125 dBA [3]. Weapons produce instant shock waves (10μs)...

Kuduwave™ testing aboard the ISS

What does it take to make an audiometer and tympanometry ready for the space age? In a recent interview, Jillian Scotland and Dirk Koekemoer shared their first-hand experience of getting the Kuduwave ready for a voyage to the ISS. It...

A bittersweet finding

This is an elegant study, documenting the role of, and activation of, nitrous oxide in chronic sinusitis. Bitter taste receptors (TR2) have recently been identified as novel ‘players’ in sinonasal innate immunity and in chronic rhinosinusitis. The receptors are triggered...

An Introduction to the Psychology of Hearing

This is the sixth edition of Brian Moore’s introductory textbook to the field of psychoacoustics, which explores the links between the physical and perceptual properties of sound. The work has been revised throughout, with references to over 100 scientific papers...

Laryngeal evaluation during COVID-19 using transcervical ultrasonography

In light of the COVID-19 pandemic, the authors highlight their protocol of transcutaneous laryngeal ultrasonography as an alternative to flexible fibreoptic laryngoscopy when appropriate. This is to reduce the risk of aerosolisation posed by laryngoscopy. Ultrasonography is a rapid, non-invasive...

Advances in neural stimulation of the auditory pathway

This article reviews the use of neuroprosthetic devices such as cochlear and auditory brainstem implants (ABI) to stimulate the auditory pathway, discussing the successes, limitations and advances in this area. Currently, neuroprosthetic devices deliver electrical impulses to the cochlear nerve...

Recurrent ENT infections in children – is it a sign of primary immunodeficiency disease?

ENT clinicians often come across children with recurrent ear, sinus and pulmonary infections. These recurrent infections, albeit common in childhood, can represent an early sign of primary immunodeficiency diseases (PIDD). PIDD is an underdiagnosed group of genetic disorders involving absent...

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...

New diagnostic criteria for Ménière’s disease – an international consensus

Most readers are familiar with the American Academy diagnostic criteria for Ménière’s disease (MD) but a significant minority will be aware of other criteria from Japan and Korea. This new effort is a collaboration between these three bodies and the...

High dose betahistine as effective as, but slower acting compared to intratympanic dexamethasone in intractable Meniere’s disease

The management of intractable Meniere’s disease poses a complex conundrum to otolaryngologists. The focus of treatment is decreasing the severity and frequency of vertigo and tinnitus whilst trying to preserve hearing. Betahistine has been used for many years in the...

What Plug?

For decades, audiologists have encouraged people to wear hearing protection when they attend concerts. Traditionally, the most accessible options have been foam plugs, which have limited appeal due to their poor sound quality. Disposable foam plugs absorb high frequency sounds...

Using the Ling-Madell-Hewitt (LMH) Test Battery

Why change a classic? Because of new knowledge and improved technology, of course! Drs Hewitt and Madell present an update to Daniel Ling’s classic speech test. One of Daniel Ling’s legacies is the Ling Six Sound Test which presents six...
