Background: Sinonasal neoplasms, whether benign and malignant, pose a significant challenge to clinicians and represent a model area for multidisciplinary collaboration in order to optimize patient care. The International Consensus Statement on Allergy and Rhinology: Sinonasal Tumors (ICSNT) aims to summarize the best available evidence and presents 48 thematic and histopathology-based topics spanning the field., Methods: In accordance with prior International Consensus Statement on Allergy and Rhinology documents, ICSNT assigned each topic as an Evidence-Based Review with Recommendations, Evidence-Based Review, and Literature Review based on the level of evidence. An international group of multidisciplinary author teams were assembled for the topic reviews using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses format, and completed sections underwent a thorough and iterative consensus-building process. The final document underwent rigorous synthesis and review prior to publication., Results: The ICSNT document consists of four major sections: general principles, benign neoplasms and lesions, malignant neoplasms, and quality of life and surveillance. It covers 48 conceptual and/or histopathology-based topics relevant to sinonasal neoplasms and masses. Topics with a high level of evidence provided specific recommendations, while other areas summarized the current state of evidence. A final section highlights research opportunities and future directions, contributing to advancing knowledge and community intervention., Conclusion: As an embodiment of the multidisciplinary and collaborative model of care in sinonasal neoplasms and masses, ICSNT was designed as a comprehensive, international, and multidisciplinary collaborative endeavor. Its primary objective is to summarize the existing evidence in the field of sinonasal neoplasms and masses., (© 2023 The Authors.

Background: We identify chronic rhinosinusitis (CRS) manifestations associated with how rhinologists assess CRS control, with a focus on patient perspectives (patient-reported CRS control)., Methods: Fifteen rhinologists were provided with real-world data from 200 CRS patients. Participating rhinologists first classified patients' CRS control as "controlled," "partly controlled," and "uncontrolled" using seven CRS manifestations reflecting European Position Paper on Rhinosinusitis and Nasal Polyps (EPOS) CRS control criteria (nasal obstruction, drainage, impaired smell, facial pain/pressure, sleep disturbance, use of systemic antibiotics/corticosteroids in past 6 months, and nasal endoscopy findings) and patient-reported CRS control. They then classified patients' CRS control without knowledge of patient-reported CRS control. Interrater reliability and agreement of rhinologist-assessed CRS control with patient-reported CRS control and EPOS guidelines were determined., Results: CRS control classification with and without knowledge of patient-reported CRS control was highly consistent across rhinologists (κ w  = 0.758). Rhinologist-assessed CRS control agreed with patient-reported CRS control significantly better when rhinologists had knowledge of patient-reported CRS control (κ w  = 0.736 vs. κ w  = 0.554, p < 0.001). Patient-reported CRS control, nasal obstruction, drainage, and endoscopy findings were most strongly associated with rhinologists' assessment of CRS control. Rhinologists' CRS control assessments weakly agreed with EPOS CRS control guidelines with (κ w  = 0.529) and without (κ w  = 0.538) patient-reported CRS control. Rhinologists classified CRS as more controlled than EPOS guidelines in almost 50% of cases., Conclusions: This study directly demonstrates the importance of patient-reported CRS control as a dominant influence on rhinologists' CRS control assessment. Knowledge of patient-reported CRS control may better align rhinologists' CRS control assessments and treatment decisions with patients' perspectives., (© 2023 The Authors.

Background: A recent analysis suggested potential narrowing of the gender gap in research productivity in the field of rhinology. This analysis did not, however, provide insight into how the genders are represented in the rhinologic literature. This study aimed to evaluate 11 years of literature to evaluate for gender differences in authorship position, collaborations, category and content of research, citations, and funding to gain perspective on how gender and authorship has changed over time., Methods: Authorship data for all articles on rhinologic subject matter published between January 1, 2008 and December 31, 2018 in four otolaryngology journals was collected. The gender of authors was determined by protocol. Category and content of research and funding status/source were additionally obtained., Results: Data were collected from 2666 articles. Gender of 14,510 authors was determined. Female authors accounted for 23% of the overall authors and male authors accounted for 77%. Female first authorship increased significantly over time, but there was no change in female senior authorship. The percentage of female authors steadily increased over time, whereas male authorship decreased slightly. Mixed gender teams were shown to be increasing in frequency. Women published more than expected in basic science and allergy and less than expected in skull base. On funded studies, women were significantly underrepresented as senior authors., Conclusion: This study represents the first assessment of gender differences in the rhinology literature. Areas where female representation can improve include senior authorship, increased involvement in skull base publications, and increased funding., (© 2021 ARS-AAOA, LLC.)

Background: Hereditary hemorrhagic telangiectasia (HHT) is an autosomal dominant hereditary disorder resulting in vascular dysplasia and formation of arteriovenous malformations. Recurrent epistaxis is a hallmark of the disease. An array of medical therapies are used in this patient population, but robust evidence-based recommendations regarding the medical treatment of epistaxis are lacking. This systematic review was performed to look at the current literature and make meaningful evidence-based recommendations., Methods: A search of the Ovid MEDLINE, Embase, and Cochrane databases was conducted by a research librarian. Abstracts in the English language and published in a peer-review journal were reviewed for relevance and inclusion. PRISMA guidelines were followed., Results: Eighteen studies met the inclusion criteria. In a few small studies, thalidomide was shown to consistently improve severity and frequency of epistaxis and improve hemoglobin concentrations while decreasing the need for transfusion. Tranexamic acid appeared to only impact the epistaxis severity score and not other clinical outcomes. Selective estrogen modulators (SERMs), propranolol, rose geranium oil, and N-acetylcysteine, have demonstrated promising efficacy in small trials., Conclusion: Appropriate medical therapies for epistaxis outcomes in HHT remain undefined, and there is no "gold standard." Many of the studies are small and the data reported are heterogeneous, and therefore the ability to make strong evidence-based recommendations is limited. However, many different medications appear to be promising options., (© 2018 ARS-AAOA, LLC.)

Background: The impact of endoscopic sinus surgery (ESS) on pulmonary function in cystic fibrosis (CF) patients with chronic rhinosinusitis remains unclear, as studies have demonstrated conflicting results. To date, no study has looked specifically at the impact of CF genotype on lung function after ESS. In this study, we reviewed changes in pulmonary function test (PFT) results after ESS in F508del homozygotes and heterozygotes., Methods: The charts of 25 patients with CF without prior lung transplant, who underwent ESS performed by the same surgeon between the period of July 2005 to July 2015, were retrospectively reviewed. Data including genotype and PFT results were collected. Patients were grouped based on genotype. Pre- and postoperative PFTs were compared., Results: Some differences in PFT outcomes after ESS could be seen on subgroup analyses. For example, when considered as a whole group, the overall cohort showed a significant improvement from preoperative FEV 1 levels at 6 months after surgery (p = 0.0127). Interestingly, on subgroup analysis, the heterozygous group saw significant improvements from preoperative FEV 1 levels at 6 and 12 months (p = 0.0155 and p = 0.0333, respectively). No significant improvements were seen from "baseline" FEV 1 in either group at any timepoint., Conclusion: Prior studies investigating the impact of ESS on pulmonary function in CF patients have shown conflicting results. To our knowledge, those earlier udies did not separate and compare different genotypes, which may have introduced heterogeneity in their patient populations. Our study suggests that grouping CF patients more strictly according to genotype or disease severity when investigating outcomes may reveal differences among various subgroups., (© 2017 ARS-AAOA, LLC.)

Background: Environmental factors such as inhaled pollutants like cigarette smoke may play a significant role in diseases of the upper airway including chronic rhinosinusitis (CRS). Recent studies have shown that cigarette smoke causes impaired airway epithelial cell barrier function likely through environmental oxidative stress related pathways. The purpose of this study is to explore whether enhancing nuclear factor erythroid 2 [NF-E2]-related factor 2 [Nrf2], the body's master antioxidant system, can ameliorate cigarette smoke-induced sinonasal epithelial cell (SNEC) barrier dysfunction., Methods: Human SNECs (HSNECs) were grown from control patients at the air-liquid interface (ALI). HSNECs were stimulated with cigarette smoke extract (CSE) with and without pharmacologic activation of Nrf2. HSNECs were then stained for the epithelial cell junctional proteins zonula occludens 1 (ZO-1) and junctional adhesion molecule A (JAM-A) using confocal microscopy. In addition, transepithelial electrical resistance (TER) was measured in cultures before and after stimulation with CSE., Results: CSE stimulation caused a global disruption of the epithelial junctional proteins ZO-1 and JAM-A along with an associated decrease in TER levels. Enhancing Nrf2 levels prior to stimulation with CSE was associated with increased localization of ZO-1 and JAM-A levels at the cell surface and statistically significant increases in TER levels., Conclusion: This is the first study to demonstrate that cigarette smoke induced SNEC barrier dysfunction is reversible by Nrf2 activation. The Nrf2 antioxidant pathway may represent a potential therapeutic target for cigarette smoke-associated sinonasal inflammation., (© 2016 ARS-AAOA, LLC.)

Background: During sinus surgery, partial or complete resection of the middle turbinate (MT) is sometimes necessary because of polypoid changes or demineralization. Topical drug delivery to the paranasal sinuses is an integral component in managing chronic rhinosinusitis (CRS) with and without nasal polyposis. The purpose of this study was to examine the role of the MT and MT resection in topical drug distribution into the sinuses via nebulization. We report on a novel technique of quantitatively evaluating the delivery of nebulized dye in cadavers., Methods: Endoscopic sinus surgery was performed on 5 fresh cadavers. Complementary colored dyes mixed with saline were successively nebulized using the following protocol: (1) fluorescein prior to MT resection; (2) brilliant green following partial MT resection; and (3) methylene blue following total MT resection. Photodocumentation of the sinuses was performed following each nebulization and standardized photoanalysis was performed., Results: Successive nebulizations with fluorescein, brilliant green, and methylene blue produced a complementary staining pattern that provided an easy side-by-side analysis of the extent of mucosal staining. Dye delivery to the frontal and sphenoid sinuses significantly increased following partial resection of the MT (p = 0.013 and p = 0.0027, respectively) and complete resection of the MT (p = 0.027 and p = 0.027, respectively). Following complete MTR, dye delivery to the maxillary sinus significantly increased compared to baseline (MT intact) (p = 0.0027)., Conclusion: Resection of the MT appears to have a significant effect on nebulized drug delivery into the frontal, maxillary, and sphenoid sinuses. Future prospective studies will help delineate the clinical relevance of this effect., (© 2016 ARS-AAOA, LLC.)
