Cochlear implants with an absent or hypoplastic cochlear nerve?
The cornerstone of successful cochlear implantation has been the presence of a population of cochlear nerve endings which are able to mount a neural response to electrical stimulation. The authors of this paper present their experience of five children with...
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...
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...
To scan or not to scan?
This comprehensive review article seeks to establish how useful is MRI in the evaluation of patients with a history of smell loss or distortion. Interestingly, while some studies found the imaging unhelpful, one paper described found a 25% rate of...
Scientific Foundations of Audiology: Perspectives from Physics, Biology, Modeling and Medicine
Scientific Foundations of Audiology – Perspectives from Physics, Biology, Modeling and Medicine is a unique textbook which discusses a wide range of state-of-the-art topics in hearing, vestibular and brain science. The editors purport that this book is geared towards doctoral...
What to do with incidental findings on FDG PET/CT?
18F-fluoro-deoxy-glucose positron emission tomography/computed tomography (FDG PET/CT) is commonly used in head and neck cancer staging. This investigation frequently identifies incidental findings unrelated to the index head and neck cancer. To assess the nature of these incidental findings, notes of...
Reliability of Koos classification
Vestibular schwannoma (VS) tumour size has been considered the primary determinant of hearing outcomes and facial nerve function according to several published studies. Varying methods are used to estimate the size and volume of the VS with very little consensus...
High definition tractography to identify cranial nerves
It has always been challenging to visualise cranial nerves on traditional imaging as the cranial nerves have a fine structure and complex anatomy. This is especially true regarding the cochlear nerve. In congenitally hearing impaired children, the visualisation of the...
Should we be doing earlier MRIs in sudden sensorineural hearing loss?
There is recognised variation between ENT departments in exact imaging protocols for the workup of idiopathic sudden sensorineural hearing loss (ISSNHL) but a routine MRI to exclude retrocochlear pathology is standard, usually following immediate treatment with oral +/- intratympanic steroids....
Do we need contrast MRI when screening for vestibular schwannoma?
Gadolinium contrast enhanced T1-weighted (gT1w) MRI images of the internal acoustic meati have long been considered the gold standard in the diagnosis of vestibular schwannoma (VS). However, the addition of contrast to the MRI examination increases the cost and time...
