A new septoplasty technique

This article describes a novel septoplasty technique to correct a cartilaginous deflection. Although it took a while to understand it as the operative photographs were not very helpful it is an interesting concept. The author excises an inferior strip and...

How can we assess children with complex needs?

In the early days of cochlear implantation, children with additional disorders were being excluded as poor candidates whereas today a large number of children with complex needs are being referred for cochlear implant assessment. However, the related problems include difficulties...

Low-frequency air-bone gaps appear to be a true audiological finding in Ménière’s disease

There is a lack of established objective tests in Ménière’s disease (MD) that can provide information about the disease process. The appearance of low-frequency air-bone gaps (LFABGs) in MD is a recognised but unexplored phenomenon. Two theories have been suggested...

Does Koos classification predict facial nerve dysfunction?

The Koos classification is a grading system used often for preoperative evaluation of acoustic tumours on imaging studies. It indirectly correlates to the size of the tumour. Size of the vestibular schwannoma is often considered the main determinant for hearing...

The telemedicine genie is out of the bottle

Delivering healthcare interventions remotely is not a new concept. The authors of this article provide a brief history dating back to the 1930s, when the International Radio Medical Centre was established to transmit medical advice to global seafarers. In the...

Speech in noise hearing difficulties

The phenomenon of speech understanding in noise in normal hearing people attracts the interest of researchers continuously. This study’s aim was to further explore the possible reasons behind these difficulties. The participants were 50 adults that reported having normal hearing...

Radiological diagnosis of mastoiditis in patients screened for acoustic neuroma

Magnetic resonance imaging is the ‘gold standard’ for screening patients suspected to have acoustic neuroma. Various abnormalities are picked up through this investigation, one of which, not uncommonly reported, is mastoiditis. This requires referral to otolaryngology and further evaluation. In...

Speech perception in the ageing population

Speech perception can present a challenge as we grow older. One of the factors responsible is, of course, hearing loss. Now research indicates that other non-auditory factors like cognitive decline may also contribute to difficulties in understanding speech. The authors...

Do nasal septal deviation and septoplasy affect Eustachian tube function?

The authors suggest that nasal septal deviation (NSD) or septoplasty possibly affect Eustachian tube (ET) function. They conclude this from their prospective study on 25 patients who underwent septoplasty for NSD. These patients aged above 14 years had no other...

Scoring system to predict hearing impairment following hemifacial spasm surgical treatment

The authors analysed brain stem auditory evoked potentials prospectively in 100 patients undergoing endoscopic microvascular decompression for management of hemifacial spasm over a period of two years. They then developed a scoring system based on electrophysiological events to predict the...

Chronic rhinosinusitis and sleep

This is an interesting article from the Chung Shan Medical University in Taiwan. One-hundred-and-thirty-nine patients were enrolled into this five-year study. They all had chronic rhinosinusitis with or without polyposis and underwent sinus surgery. The aim was to investigate a...

Hearing preservation and device benefit following implantation of short or hybrid electrodes

Hybrid or short electrodes have increasingly been used in the literature in order to combine electrical with hearing-aid stimulation. However, hearing preservation of the residual low-frequencies are of utmost importance in this attempt. The present study compared hearing preservation and...
