BAHA stability measurement in children

This useful paper reports the experience of using resonance frequency analysis for single stage bone-conduction implants in a paediatric population. A smartpegTM is attached to the abutment and vibrated by a close quarters magnetic field. The amount of vibration is...

Early vs late activation of cochlear implant device

Device activation after cochlear implant surgery was typically performed after wound healing, and varies anytime from three to four weeks after surgery. Nowadays, activation is performed as early as two to three days after surgery. The authors evaluated the effect...

Asymmetrical hearing loss following prolonged occupational noise exposure

Noise-induced hearing loss (NIHL) is one of the commonest occupational conditions and has been linked with increased risk of work-related injuries. Noise-induced hearing loss is traditionally associated with bilateral symmetrical sensorineural hearing loss unless they are exposed to unilateral noises,...

Hearing preservation in CI, any predictors?

The electrically evoked compound action potential (eCAP), obtained non-invasively from cochlear implant (CI) recipients, represents a population response of the auditory nerve to electrical stimulation. The eCAP characteristics include threshold (the lower the better), growth of response (the steeper the...

Long-term results of incus vibroplasty in patients with moderate-to-severe sensorineural hearing loss

The Vibrant Soundbridge (VSB) middle ear implant is now a well-accepted and widely utilised treatment option for patients with sensorineural hearing loss unable to use standard hearing aids. However, as a relatively recent addition to the portfolio of implants available...

Music is noise

Marshall Chasin recaps what we know acoustically about music and noise, and discusses the potentially damaging levels of music, how temporary threshold shift (TTS) is not necessarily temporary and gives us some considerations for protective devices for musicians. Most of...

Complications associated with microlaryngoscopy surgery

Microlaryngoscopy procedures are often considered to be routine procedures at the straightforward end of the ENT operative spectrum. Complications associated with this surgery are thought to be infrequent and primarily related to the possibility of dental trauma and adverse voice...

Taking a fresh look at otoacoustic emissions

So what has changed in four decades of OAEs? Do we now have all the answers? Have we reached our optimum recording ability? Professor Kemp explains what we know, what we don’t know and what’s to come. In the 40...

Hearing loss prevention in musicians - violating one rule of physics

Whilst enjoying music, we also need to be mindful of the potential effect of producing music for the musician. Dr Chasin discusses the development of earplugs for the industry with the added bonus of physics for party goers! Hearing protection,...

MRI in diagnosis Meniere’s disease: what is the evidence?

The utility of magnetic resonance imaging (MRI) in the diagnosis of Meniere’s disease (MD) has attracted a lot of interest recently. It is well accepted that the saccule is the most common vestibular organ affected by endolymphatic hydrops (EH) and...

Central auditory changes in SNHL

Robert Harrison discusses some of the most obvious ways in which cochlear hearing loss has central consequences. It is convenient to classify hearing loss according to the most obvious site of lesion, for example, conductive, cochlear, retro-cochlear, or central hearing...

Otological problems in musicians

Musicians are understandably anxious about their hearing, and recent high-profile cases of noise-related hearing loss have resulted in huge changes in the music industry. Chris Aldren (otologist and violinist) explains. In the recent Oscar-winning movie, Sound of Metal, heavy metal...
