Which factors affect the postoperative CSF leak following endoscopic skull base surgery?
Endoscopic skull base surgery is being increasingly performed worldwide for skull base tumours. Common indications include pituitary tumours, rathke cleft cysts, chordomas, craniopharyngiomas and olfactory neuroblastomas. The most common and important complication following endoscopic skull base surgery is postoperative CSF...
Management of postoperative cholesteatoma
This prospective longitudinal observational study compared the ability of second-look surgery with that of surveillance using serial non-echo-planar diffusion-weighted imaging to detect residual cholesteatoma after canal wall-up mastoidectomy. A total of 34 patients were included in the study who underwent...
Benign oesophageal strictures: overview and management strategies
Benign oesophageal strictures may have several attributable causes including caustic injuries, long-term acid reflux, eosinophilic oesophagitis, anastomotic strictures and endoscopic therapy. Endoscopic dilation via bougies or balloon dilators may treat most strictures successfully and satisfactorily. However, in some situations treatment...
Outcomes at three years post-implantation of the Bonebridge device
This is a MED-EL-funded study of the hearing outcomes and complication rates of the Bonebridge active transcutaneous bone conduction implant (BCI). The authors have declared no conflict of interest. Follow-up occurred at intervals for 36 months post-implantation in all 57...
Robotic insertion of electrode array in cochlear implantation
Cochlear implants (CIs) are commonly used for profound bilateral hearing loss. They have specific national guidance for their insertion, however patients with a substantial residual acoustic hearing are potential CI candidates. Preservation of this residual hearing can be sought with...
Algorithms to diagnose NIHL
Finding an efficient diagnostic tool for noise-induced hearing loss (NIHL) has been of research interest for a long time. There are several algorithms that compare expected age-related deterioration of hearing with the actual audiogram. This study aimed to compare a...
Long-term effectiveness of sleep surgery for obstructive sleep apnoea
n this study, 39 patients from Turkey with obstructive sleep apnoea (of varying severity) underwent an expansion sphincter pharyngoplasty. This operation was devised by Prof Kenny Pang in Singapore and involves using the palatopharyngeus muscle and partly relocating it laterally...
Impedance for different electrode types
Measuring cochlear implant (CI) electrode impedances is common in CI programming appointments to measure the integrity of the implant e.g. whether there are any open or short electrodes. This is because impedance measures the flow of current between intra and...
Coblation for laryngeal granulomas
Laryngeal granulomas remain notorious for their tendency to recur after surgical removal. Although high rates of complete remission have been reported with use of the potassium-titanyl-phosphate (KTP) laser, this equipment is expensive and not available in all units performing ENT...
Role of maxillary sinus irrigation as an adjuvant to current management of chronic rhinusitis without polyposis
Several decades have passed since irrigation of maxillary sinuses generally became a treatment of the past. A more recent concept of biofilms may have evoked new interest in this past procedure, fraught with its own issues. In this study, the...
Take a breath between mouthfuls
Pulse oximetry provides a measure of the percentage of oxygen in the blood. The usual range of readings on pulse oximetry is 97-99%. Older people may have lower pulse oximetry readings than younger people, and young women have higher readings...
