Nasal septal perforations (NSPs) often cause bleeding, crusting, obstruction, and/or whistling. The objective was to analyze the impact of anterior NSP size and shape on nasal physiology using computational fluid dynamics (CFD).

We report a novel surgical technique based on an endonasal free mucosal graft (mucoplasty) for improving clinical results and local healing in chronic rhinosinusitis with nasal polyps (CRSwNP).

In recent years non-allergic rhinitis has received a lot of interest; in particular the different phenotypes, endotypes, the impact on quality of life and the potential role of IgE in local allergic rhinitis (LAR). The prevalence of LAR reported in the literature has been extremely variable (0-100%); Hamizan’s review in this issue explains many of these discrepancies. The overall prevalence of IgE in nasal secretion was found to be 10.2 (7.4-13.4) %. However, where there is history of an identifiable aeroallergen which triggered nasal symptoms or seasonality of symptoms, the prevalence is 19.8 (14.5- 25.6) %. On the other hand, patients who lacked a suggestive allergy history and had negative systemic allergy tests had zero probability of detectable nasal serum IgE (0 (0-3.1) %). This useful review highlights history taking as a simple method to filter potential LAR patients from the general NAR population. This is important because LAR patients significantly differ from other phenotypes of NAR, not only in terms of symptoms, but also the likelihood of developing asthma and susceptibility to treatment.

In order to perform endoscopic sinus surgery (ESS) safely and efficiently, preparation of the nasal mucosa with vasoconstrictor agents is crucial to minimise bleeding. There is no single best method, although traditionally cocaine has been the agent of choice. However, there have been concerns over the potential for systemic side effects when applied topically. With this concern in mind, there exists limited contemporary research looking at cocaine absorption in the context of ESS. This study aims to determine the amount and duration of systemic cocaine absorption after intranasal atomised administration of modified Moffett’s solution prior to ESS.

There is a paucity of high-quality evidence relating to the management of epistaxis severe enough to require admission to a hospital. Previous studies of interventions for epistaxis have suffered from small sample sizes. They lacked the power to allow analysis of the effect of an intervention on epistaxis control that is independent of the condition severity or additional interventions given.

No diagnostic criteria have been available for nonallergic rhinitis (NAR) to this point in time. Nonspecific nasal hyperresponsiveness (NHR), which could be efficiently assessed by cold dry air (CDA) provocation, is an essential feature of NAR. Thus, this study’s purpose was to assess the diagnostic value of CDA provocation in discriminating patients with NAR from healthy individuals.

While bacterial associations with chronic rhinosinusitis (CRS) are increasingly well described, fewer studies have examined the fungal component of the sinonasal microbiota. Here we present a study of the sinonasal mycobiota in a cohort of 144 patients (106 patients with CRS and 38 controls).

Local allergic rhinitis (LAR) is found in some patients with typical symptoms but who have negative skin prick tests and negative IgE to aeroallergens while presenting with positive nasal provocation tests for proper allergens. Little information about the clinical characteristics and prevalence of LAR has been published. The aim of this study was to determine the prevalence and characteristics of LAR in patients with symptoms of chronic rhinitis.

Prospective study investigating the incidence of concurrent Eustachian Tube dysfunction (ETD) in patients with CRS refractory to medical therapy, and the effect of Endoscopic Sinus Surgery (ESS) on ETD in this patient group.

Airway epithelial cells have a well-accepted role in the regulation of local inflammatory processes in allergic and innate defence responses. However, their role the pathophysiology of chronic rhinosinusitis with nasal polyps (CRSwNP) is unclear. The objective was to investigate whether potential differences in the mRNA expression profile of nasal epithelia from healthy individuals and from CRSwNP patients would shed new light on disease mechanisms.
