Preoperative CT checklist (using the ‘CLOSE’ mnemonic) improves identification of anatomical variants for endoscopic sinus surgery

Computed tomography (CT) scans of the paranasal sinuses act as roadmaps for endoscopic sinus surgery (ESS) and careful inspection preoperatively warns the operating surgeon of critical anatomical variants. This study aimed to investigate if implementation of a pre-ESS CT checklist...

Is there time for intraoperative scans?

Intraoperative imaging plays an integral role in orthopaedic surgery during the repair of long-bone fracture. Given the complexity of the facial skeleton, intraoperative imaging has the potential for similar benefits in reconstructive surgery. The objectives of the study were to...

Thyroid nodule update

This excellent article summarises the current diagnostic difficulties with an endocrine gland that frequently produces nodules, some of which may harbour malignancy. At 50 years of age and over there is about a 50% chance of having a nodule; at...

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...

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...

Diagnostic criteria for superior semicircular canal dehiscence syndrome

The latest Bárány Society’s consensus document on diagnostic criteria for vestibular disorders is one for superior semicircular canal dehiscence syndrome (SCDS). There are three major categories: (A) Symptoms consistent with a third mobile labyrinthine window; (B) Physiologic tests – clinical...

Innovation in medical product technologies

There is a point in all innovation projects where the clinician has exhausted their knowledge and needs expert help to create a prototype. Mark Prince, Design Engineer, discusses this phase of the project and how engineers’ analytical thinking brings a...
