Narrow band imaging in laryngopharyngeal reflux

Narrow band imaging (NBI) is a tool on the Olympus endoscopic systems that uses blue and green wavelengths to enhance visualisation of mucosal vasculature. It has been used to aid in the early diagnosis of upper aerodigestive tract cancers. A...

Sinus implants to treat recalcitrant polyps

It is well established that the burden of chronic rhinosinusitis on healthcare costs and patients’ quality of life is high, and that current mainstream treatment options of oral or topical steroids are not without problems. This paper compares two RCTSs...

Helicobacter pylori infection delays mucociliary clearance in the nose

Chronic rhinosinusitis is not uncommonly a difficult condition to treat and therefore any possible association of this condition with factors outside the nose and sinuses is the subject of worthwhile research. Impairment of mucociliary clearance is paramount to upper respiratory...

Swallow this: management of dysphagia post-stroke

We know that between 50% and 80% of people who have had a stroke present with swallowing difficulties that may be associated with even a small lesion of the cortical or subcortical brain regions. This article provides an up-to-date overview...

The GP and the ear

General practitioners are the first members of the medical community to deal with ear problems. In this survey, 11 GPs examined 124 patients using a regular otoscope and a video-otoscope and reported their findings in a 10-item table. The same...

An eye-opening resection technique

It is widely accepted that the gold standard treatment of inverted papilloma of the maxillary sinus (IPMS) is endoscopic excision via medical maxillectomy or mega antrostomy, and these approaches can be augmented by a Caldwell-Luc or canine fossa trephination if...

Dacryocystorhinostomy revisited

In this technical variant, instead of seeking the lacrimal sac, the authors describe a retrograde technique. They first identify the nasolacrimal duct at the level of the most anterior insertion of the inferior turbinate in the lateral nasal wall. The...

Widen the ostium or keep it: that is the question

The original concept of wide endoscopic sphenoethmoidectomy for sinonasal polyposis has been a well-established principle since 1995. However, with the evolution of the understanding of sinonasal physiology, this might change. The authors present arguments based on the evolutionary and developmental...

Instrument assessment preferable over standard beside swallow to determine prevalence of aspiration

Aspiration does not trigger the protective cough response in some patients. The patient’s response may vary according to fluid viscosities and volume. The authors of this prospective study investigated the prevalence of aspiration and response to aspiration of different viscosities...

An unrecognised anatomical variant which may help frontal sinus surgery

Anatomic variants in the frontal sinus have significant implications in endoscopic sinus surgery. In this illustrative study, the authors describe a newly-observed anatomical variant – a mucosa lined prism‑shaped space between the most superior part of the nasal septum and...

IL-25 and nasal polyps, another target

Immune response in chronic rhinosinusitis with nasal polyps (CRSwNP) is mainly via type 2 T-helper (Th2) cells while Th1 cells characterise chronic rhinosinusitis without nasal polyps (CRSsNP) immune response. CRSwNP is heterogeneous on a cytological level causing a varied response...

What is balloon eustachian tuboplasty (BET)?

Eustachian tube dysfunction (ETD) is the result of a combination of factors that interfere with the mucosal functional or cartilaginous structures. Failure to open the eustachian tubes can cause aural pain, pressure in the ears, muffled hearing, crackling/popping sounds in...
