Forward-going sound pressure wave with hearing thresholds

This article discusses an important and well-known point regarding the differences between coupler sound pressure measurements, used to calibrate earphones, and actual pressures delivered to the ear due to individual variances across patients. The study purports to suggest a new...

The perils of poor postop blood pressure control

This retrospective case control study reviews 621 patients undergoing thyroid surgery over a 10-year period from 2002-2012 looking at postoperative haemorrhage rates. This potentially catastrophic complication warrants close analysis in order to best discern how it can be minimised. The...

Treating keloid scarring with pressure clips following excision: does it work?

Keloid scars can pose a difficult management problem. Whilst not harmful in themselves they can be cosmetically unappealing and lead to social embarrassment and resulting isolation, and following surgical excision they often reoccur. Mechanical pressure is an adjuvant to surgical...

Development of a new negative-pressure ventilatory support device: Exovent

The pandemic has driven innovation in ways that we have not seen for many decades. Intensive care medicine and ENT have been at the forefront of these advances, and our good friends David Howard (never one to put his feet...

Effectiveness of oral pressure therapy in obstructive sleep apnoea: a systematic analysis

Oral pressure therapy (OPT) is a relatively new form of therapy for obstructive sleep apnoea (OSA). Paradoxically it seems to work even though it creates a vacuum in the oral cavity as opposed to the gold standard of continuous positive...

Curettage adenoidectomy impairs eustachian tube function

Adenoidectomy is a common procedure undertaken for obstructive sleep apnoea and nasal obstruction. Curettage is the most common technique but is associated with complications (mucosal trauma, bleeding) that may cause eustachian tube dysfunction (ETD). This study analysed changes in middle...

Maturation of BC attenuation

The aim of this study was to clarify the reason for differences between bone-conduction hearing in adults and infants. The authors investigated how the sound pressure level in the ear canal changes depending on the bone-conduction transducer placement. By using...

Middle ear pressures with different anaesthetic agents

The use of appropriate anaesthetic agents is essential to avoid complications during middle ear surgery. This Turkish study attempted to identify whether intravenous (IV) anaesthetics (propofol) or inhalational agents (sevoflurane) cause more variations in middle ear pressures. The authors performed...

Alternobaric vertigo: asymmetrical vestibular function due to asymmetrical middle ear pressures (Iron Man’s archenemy)

The Marvel Cinematic Universe could certainly be deemed an ‘extreme environment’ and yet very rarely do we see the Avenger’s popping to the clinic for a check-up. Hee-Young Kim has wondered how they cope with extreme pressure changes and discusses...

Increasing tongue strength to reduce dysphagia: what is the potential benefit of a device driven exercise?

Weakness in tongue muscle strength and laryngeal elevation is known to have an adverse impact on swallowing function. Various swallowing exercises are often recommended to improve function of these important structures with the goal of preventing aspiration and improving swallow...

The role of the respiratory physician in sleep medicine

ENT surgeons may feel that they are the first point of referral for the majority of patients with snoring and possible obstructive sleep apnoea, but in reality a significant number of patients with sleep-disordered breathing (of any cause) are seen...

Neurological idiopathic disease: a shared journey for NASA and medicine

Whilst Southampton can’t really be described as an extreme environment, experiments carried out in the city have certainly been taken out of this world. Robert Marchbanks discusses one of the associations between Southampton, The International Space Station and tympanic membrane...
