Surgery for Cochlear and Other Auditory Implants

Make no mistake, this is a big book. Admittedly it’s not as big as Scott-Brown, which Liam Flood couldn’t carry from his office to his car without resting several times, but it’s still a whopping beast. Measuring 32cm in height...

Role of non-echo planar diffusion weighted magnetic resonance imaging in detection of cholesteatoma

Whilst the method of canal wall down and same-session reconstruction is emerging to be more popular, canal wall up procedures are still performed. In either, it is necessary to ensure eradication of cholesteatoma or detect its recurrence. The reliability of...

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...

Role of imaging in unilateral sensorineural hearing loss

Recent understanding of the significance of unilateral hearing loss in children for language development calls for extensive investigations and early rehabilitation. This retrospective study of 90 children with unilateral hearing loss with high resolution CT scans and MRI revealed that...

Clinical histopathology of 250 parotidectomy patients

Clinical histopathology of 250 parotidectomy patients This is a retrospective study of 250 consecutive parotidectomy patients at units in Belgium and the Netherlands. The sensitivity and specificity of FNAC was 64% and 99% respectively, the sensitivity being slightly lower than...

Diagnosing complications of acute mastoiditis in emergency situations

In many cases, acute mastoiditis is manageable with intravenous antibiotics and hospitalised care. However, the decision whether to intervene surgically remains crucial and reliance is based on radiological findings – CT scans for bony changes and MRI for possible intra-cerebral...

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...

Two for the price of one - multiple parotid neoplasms

With advancing years come many benefits, but one drawback is the acquisition of parotid (or thyroid) neoplasms. Conventional teaching is that most are benign and slowly enlarge, and not infrequently are found bilaterally as in Warthin’s. Pleomorphic adenomas are also...

Imaging tinnitus

Tinnitus is a common sensation with a reported prevalence of 7-32%. The British National Study of Hearing recorded that 10% of adults suffered from prolong spontaneous tinnitus, and approximately a quarter of these are subsequently referred to hospital for investigation...

Hidden hearing loss in humans: cochlear synaptopathy is superseded by cognitive effects when listening to speech in noise

Elizabeth Beach presents an overview of the recent research being undertaken at the National Acoustic Laboratories on speech in noise and its relationship to cochlear synaptopathy. Our team at the National Acoustic Laboratories (NAL) has been investigating hidden hearing loss...

Is clinical HIT as good as vHIT in the emergency room?

Establishing the cause of acute vestibular syndrome (AVS) is critical in the first few hours of presentation in the emergency department. The first question to ask is, “is it due to a peripheral vestibular pathology or a stroke?” This is...

In conversation with Professor Paul J Donald

Prof Paul J Donald has recently stepped down as Chairman of the ORL-HN Department at UC Davis in Sacramento and is winding down to retirement. In this interview with Prof Pat Bradley, Prof Donald explains some of the highlights of...
