Your voice and your personality

Variations of vocal effort are a normal adaptation to difficult communication situations. However, persistence of these abnormal strategies can lead to various functional dysphonias. In this experiment, the authors tested 41 females aged 18-52. The subjects were asked to instruct...

Follow-up of NF2 patients with ABRs, SDS and MRI

Hearing loss is one of the earliest manifestations in vestibular schwannomas with 60% of the patients having high frequency loss. Several metabolic and mechanical factors influencing the cochlea and cochlear nerve have been implicated in the hearing decline noted in...

Paediatric versus adult pituitary adenomas

This retrospective study compares paediatric with adult patients undergoing pituitary adenoma surgery over a period of 26 years at a single institution. All surgeries were performed via a sublabial approach using the operating microscope. An endoscope was used occasionally for...

How many friends will you have after a TBI?

Friendships are key to reducing stress and improving morale and social support. Loss of friendships after a traumatic brain injury (TBI) can have a significant impact on these areas of a person’s life. There is little in the research literature...

The role of cVEMPs in the diagnosis of Meniere’s disease

This study sets out to determine the most useful metrics to use from cervical-vestibular evoked myogenic potential (c-VEMP) tests when the diagnosis of Meniere’s disease (MD) is unclear, or as a follow-up tool. It is known that cVEMPs can detect...

Conductive hearing loss and temporal processing

This Turkish study looked at the effect of using hearing aids on auditory temporal processing (the ability of the hearing system to process the temporal properties of a sound stimulus in a certain period of time) in conductive hearing loss....

Is there a role for hyperbaric treatment in sudden hearing loss?

Sudden sensorineural hearing loss is a common presentation to ENT departments with a significant difference in management both at a local and regional level. The authors seek to clarify the role of hyperbaric oxygen therapy in combination with oral and...

Interleukins, cilia and polyps

Interleukins (ILs) including IL13 (Th2 cytokine) are inflammatory mediators and their role in asthma has been detailed before. This study explores IL13 receptor expression in chronic rhinosinusitis with nasal polyps (CRSwNP). The authors investigate protein and mRNA expression levels of...

Blindness after orthognathic surgery

This is a case report and review of the literature of this rare, but well recognised alarming complication. The authors discuss the possible mechanisms, suggesting that it does not arise from a direct injury to the optic nerve and is...

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...

Increased intensity of treatment: intensity does not improve outcomes

There is a paucity of reports regarding the intensity and appropriate duration of treatment required to improve the language abilities of children with language impairment. This study used direct measures such as the time spent on language, the frequency, number...

Effects of age on neuro-physiological processing of speech at brainstem level

Degenerative changes associated with ageing may affect processing of spectral and temporal cues in speech at cortical and subcortical levels, even though these individuals may have normal audiometric thresholds. These changes are more likely to be picked up by speech...
