Nasal branch of the anterior ethmoid artery: a consistent landmark for a midline approach to the frontal sinus.

Frontal sinusotomy can be challenging when significant scarring or distorted anatomy is present. Identifying a reliable anatomic structure, when traditional landmarks or navigation are absent, may assist the surgeon in revision and complicated frontal sinusotomies via a midline approach. We aimed to characterize the anatomic relationship of the nasal branch of the anterior ethmoid artery (NBAEA) to the frontal infundibulum, specifically the first olfactory fili, posterior frontal infundibulum, and anterior ...

Influence of a medialized middle turbinate on olfactory function: a prospective randomized double-blind study.

Medialization of the middle turbinate (MT) is an effective technique to prevent recurrent rhinosinusitis but could, in theory, reduce olfactory function by interfering the odorants to reach the olfactory mucosae. We performed a prospective randomized double-blind trial under the hypothesis that olfactory functions would be affected by the status of olfactory mucosae, not by MT medialization.

Determinants of noticeable symptom improvement despite sub-MCID change in SNOT-22 score after treatment for chronic rhinosinusitis.

The minimal clinically important difference (MCID) of the 22-item Sino-Nasal Outcome Test (SNOT-22) is specific but not sensitive for identifying patients experiencing noticeable improvement in symptoms of chronic rhinosinusitis (CRS). It is unclear why some patients with less than 1 MCID change in SNOT-22 score nevertheless report noticeable improvement in their CRS symptoms.

Semaphorin 3A inhibits allergic inflammation by regulating immune responses in a mouse model of allergic rhinitis.

It has been reported that semaphorin 3A (sema3A) could improve allergic symptoms in allergic rhinitis (AR) mice. However, the immunomodulatory roles of sema3A in AR remain unclear. This study was performed to determine the immunoregulatory effects of sema3A on airway inflammation in an AR mice model.

Utilization of a novel interactive mobile health platform to evaluate functional outcomes and pain following septoplasty and functional endoscopic sinus surgery.

Whether for research or quality improvement, assessment of postoperative quality of life outcomes faces a challenge in reliable data collection. Typical coordinator-led studies cite response rates from 35% to 70%. This study evaluates the utility of a digital patient engagement platform to track patient-reported outcome measures (PROMs) following septoplasty and functional endoscopic sinus surgery (FESS).

Therapeutic use of steroids in non-chronic rhinosinusitis olfactory dysfunction: a systematic evidence-based review with recommendations.

Olfactory loss is a common and debilitating disease with limited treatment options, particularly for olfactory dysfunction not related to sinonasal inflammation. Both topical and systemic steroids have been used as treatments for olfactory loss. This study systematically reviews the literature on the efficacy of steroids for non-chronic rhinosinusitis (CRS)-related olfactory loss and provides recommendations.

Ivacaftor improves rhinologic, psychologic, and sleep-related quality of life in G551D cystic fibrosis patients.

Ivacaftor is a cystic fibrosis transmembrane conductance regulator (CFTR) potentiator that improves pulmonary function in cystic fibrosis (CF) patients with at least 1 copy of the G551D CFTR mutation. The purpose of this study is to evaluate the impact of ivacaftor on chronic rhinosinusitis (CRS) symptoms in this population.

Interleukin-4-induced posttranscriptional gene regulation of CCL26 by the RNA-binding protein HuR in primary human nasal polyp-derived epithelial cells.

Much attention on the pathophysiology of nasal polyp (NP) has focused on eosinophils. Interleukin (IL)-4 and eotaxin-3 (C-C motif chemokine ligand 26, or CCL26) levels have been reported to be increased in eosinophilic nasal polyps. The aim of this study was to characterize CCL26 posttranscriptional regulation by the RNA-binding protein HuR in primary human nasal polyp-derived epithelial cells (hNPDECs) challenged with IL-4.

Surgical simulation of a catastrophic internal carotid artery injury: a laser-sintered model.

The catastrophic and rare nature of an internal carotid artery (ICA) injury during endonasal surgery limits training opportunities. Cadaveric and animal simulation models have been proposed, but expense and complicated logistics have limited their adoption. Three-dimensional (3D) printed models are portable, modular, reusable, less costly, and proven to improve psychomotor skills required for managing different lesions. In this study we evaluate the role of a simplified laser-sintered model combined with st...

Independent predictive factors for the persistence and tolerance of cow's milk allergy.

Cow's milk protein allergy (CMPA) is usually transient, with most children tolerating ingested cow's milk by 3 years of age. This study aimed to determine factors that promote or hindering the development of tolerance to CMPA.

Rising to the challenges of precision medicine: nasal inflammation research in China.

Highlights of eosinophilic chronic rhinosinusitis with nasal polyps in definition, prognosis, and advancement.

Tissue eosinophils are characteristic of inflammation in most but not all patients with chronic rhinosinusitis with nasal polyps (CRSwNP) and may be useful for defining subgroups and making treatment choices. However, no consistent diagnostic criteria for CRSwNP with eosinophilic inflammation have been established.

Adoptive cell therapy of tolerogenic dendritic cells as inducer of regulatory T cells in allergic rhinitis.

Regulatory T cells (Tregs) have become promising candidates for immunotherapy in allergic rhinitis (AR). The contributing role of tolerogenic dendritic cells (tDCs) in the augmentation of Tregs in AR remains to be determined.

B cell lymphoma-2-like protein-12 association with T-helper 2 inflammation in chronic rhinosinusitis with allergy.

T-helper 2 (Th2) polarization plays a critical role in the pathogenesis of chronic rhinosinusitis (CRS) with accompanying nasal allergy. Recent studies indicate that B cell lymphoma-2-like protein-12 (Bcl2L12) is associated with immune dysregulation. The purpose of this study was to elucidate the role of Bcl2L12 in the pathogenesis of Th2 polarization of CRS patients.

SNOT-22 score patterns strongly negatively predict chronic rhinosinusitis in patients with headache.

Differentiating the non-sinogenic headache from chronic rhinosinusitis (CRS) remains a significant clinical challenge due to the extensive overlap in symptoms. The objective of this study was to evaluate the 22-item Sino-Nasal Outcome Test (SNOT-22) score patterns in patients with confirmed non-sinogenic headache in order to develop negative predictors of CRS.

Impact of chronic rhinosinusitis on sleep: a controlled clinical study.

Earlier studies have suggested that patients with chronic rhinosinusitis (CRS) report worse sleep quality than population norms. What remains unknown is whether these patients are actually experiencing measurable changes in objective sleep parameters. The goal of this study was to prospectively evaluate objective sleep measures in a cohort of patients with CRS.

Deletion of Nrf2 enhances susceptibility to eosinophilic sinonasal inflammation in a murine model of rhinosinusitis.

Oxidative stress exacerbates lower airway diseases including asthma and chronic obstructive pulmonary disease (COPD); however, its role in upper airway (sinonasal) chronic inflammatory disorders is less clear. Nuclear erythroid 2 p45-related factor (Nrf2) is an endogenous mechanism that upon activation invokes an antioxidant response pathway via nuclear translocation and upregulation of cytoprotective genes. We sought to determine whether deletion of Nrf2 enhances susceptibility to allergic sinonasal inflam...

Management and outcome of epistaxis under direct oral anticoagulants: a comparison with warfarin.

Epistaxis is one of the more common reasons for emergency room visits. The main risk factor for epistaxis is anticoagulant therapy. Until recently, the main culprit was oral intake of a vitamin K antagonist, such as warfarin, which has a number of side effects. Even more recently, several direct oral anticoagulants, rivaroxaban and dabigatran, have been approved for use. We investigated the possible differences between treatment of epistaxis with direct oral anticoagulants and vitamin K antagonists.

Deficiency in interleukin-10 production by M2 macrophages in eosinophilic chronic rhinosinusitis with nasal polyps.

M2 macrophages are characterized by high interleukin-10 (IL-10) expression and are critical for resolving inflammation. Although increased accumulation of M2 macrophages has been demonstrated in chronic rhinosinusitis with nasal polyps (CRSwNP), particularly the eosinophilic type, their functional relevance in CRSwNP remains poorly understood.

Effects of mometasone furoate-impregnated biodegradable nasal dressing on endoscopic appearance in healing process following endoscopic sinus surgery: a randomized, double-blind, placebo-controlled study.

Postoperative care is an important factor affecting the outcome of endoscopic sinus surgery (ESS) in patients with chronic rhinosinusitis (CRS). The aim of this study was to test the effect of mometasone furoate (MF)-soaked biodegradable nasal dressings (BNDs) on endoscopic appearance in CRS patients with nasal polyps (CRSwNP) after ESS.

Allergic rhinitis and the associated risk of nocturnal enuresis in children: a nationwide population-based cohort study.

Despite controversy, an association between allergy and nocturnal enuresis (NE) has been reported for almost a century. Allergic rhinitis (AR)-associated sleep-disordered breathing frequently results in microarousals during sleep, decreased sleep efficiency, and change in sleep pattern and behavior. NE is a common sleep disorder in children. Hence, this study aimed to investigate the incidence and risk of NE in children with AR.

Unsupervised cluster analysis of chronic rhinosinusitis with nasal polyp using routinely available clinical markers and its implication in treatment outcomes.

Chronic rhinosinusitis with nasal polyps (CRSwNP) is a multidimensional disease. In this study, we performed an unsupervised cluster analysis of CRSwNP using routinely available clinical markers.

Sentinels at the wall: epithelial-derived cytokines serve as triggers of upper airway type 2 inflammation.

Recent evidence has demonstrated an expanding role of respiratory epithelial cells in immune surveillance and modulation. Studies have been focusing on the earliest events that link epithelial injury to downstream inflammatory responses. Cytokines produced by and released from respiratory epithelial cells are among these early trigger signals. Epithelial-derived cytokines, namely thymic stromal lymphopoietin (TSLP), interleukin (IL)-25, and IL-33, have come to the forefront of recent investigations. Each of...

Impact of genetic variants of GLCCI1 on operational therapy in Chinese chronic rhinosinusitis patients.

Endoscopic surgery and postoperative glucocorticoids may effectively control inflammation in patients with chronic rhinosinusitis (CRS). However, some patients who are insensitive to glucocorticoids have a poor prognosis. Studies have shown that the GLCCI1 polymorphism is related to sensitivity to glucocorticoids, but no study has been conducted in China to investigate the relationship between GLCCI1 polymorphisms and postoperative prognosis of CRS.
