BACKGROUND: The endocannabinoid system represents a highly conserved, innate signaling network with direct and indirect control of eicosanoid-mediated inflammation. Activation of the type 2 cannabinoid receptor (CB2R) leads to decreased type 2 inflammation and reduced production of arachidonic acid (AA). Given that altered AA metabolism is associated with aspirin-exacerbated respiratory disease (AERD), we hypothesized that expression of the CB2R gene CNR2 is increased in AERD. METHODS: Nasal polyps from consecutive patients undergoing endoscopic sinus surgery for AERD or allergic fungal rhinosinusitis (AFRS) were prospectively evaluated...

R Jankowski, C Rumeau, D T Nguyen, P Gallet
Nasalisation is a surgical technique proposed for the treatment of nasal polyposis in 1995. The technique as initially described was based on large opening of the maxillary, sphenoidal and frontal ostia and resection of the middle turbinates, with the aim of resecting the mucosa of the lateral masses of the ethmoid as completely and safely as possible. Recent findings on the evolution and development of the nose and sinuses and sinus physiology allow both the concept and the technique of nasalisation to be updated...

BACKGROUND: Chronic rhinosinusitis (CRS) is a diverse clinical syndrome with a heterogeneous pathophysiology. Early attempts to identify CRS endotypes and biomarkers have largely relied on analysis of surgically obtained tissue, thus limiting their practical utility. This study examined the ability of mucus T helper 2 (Th2) biomarkers to predict CRS disease severity and clinical characteristics. METHODS: CRS (n = 90) and healthy control subjects (n = 17) were prospectively enrolled prior to surgical intervention and mucus levels of interleukin (IL)-4, IL-5, and IL-13 were determined using a multiplex cytometric bead assay...

BACKGROUND: The ostiomeatal complex (OMC), comprising a small natural maxillary sinus ostium and narrow infundibulum, transmits the air diffusion into the antrum and mucociliary transport from the antrum, and is considered a key area in chronic rhinosinusitis (CRS). Thin membranous anterior and posterior fontanelle areas below the OMC can rupture forming a perforation, accessory maxillary ostium (AMO), that increases antral airflow changing the anatomy and function of the sinus. The purpose of this study was to report the first case series of CRS patients who had undergone repair of fontanelle defects aiming to reconstruct normal structures...

REVIEW
Y J Chen, X B Chai
Chronic rhinosinusitis with or without nasal polyps mainly uses combination of medications represented by nasal glucocorticoids and functional sinus endoscopic surgery (FESS) and comprehensive treatment with antibiotics. The effect of oral antibiotics for CRS exacerbations on the microbial resistance rate in the population has not yet been fully assessed, but may be significant, and glucocorticoid-resistant CRS has also emerged. CRSwNP associated with complications of asthma is considered a more serious condition...
