ObjectiveTo objectively identify and quantitate presenting nasal symptoms in patients with a septal perforation using the validated NOSE‐Perf scale.Study DesignCase series retrospective review.MethodsThe medical records from August 2018 through January 2022 of patients at a tertiary care academic center with a septal perforation, and who completed the NOSE‐Perf questionnaire, were reviewed. Perforation symptoms were identified and quantified using the 12‐item NOSE‐Perf scale (score range 0–48). NOSE‐Perf findings were correlated to patient demographics, perforation etiology, and perforation length. NOSE‐Perf scores of patients who pursued treatment were compared with those who did not.ResultsNOSE‐Perf data were collected from 202 patients. Nasal crusting was noted in 94.1% of patients and was the most severe symptom reported (mean 2.9 of 4.0). Nasal congestion, difficulty breathing, and nasal obstruction followed in prevalence and severity. The mean total NOSE‐Perf score was 23.7. Linear regression analysis demonstrated a weakly negative association of NOSE‐Perf score with patient age and weakly positive association with increasing perforation length. NOSE‐Perf scores were significantly higher in women and in patients pursuing treatment.ConclusionThis is the first study to use the validated NOSE‐Perf scale to objectively characterize and establish baseline septal perforation symptomatology. The NOSE‐Perf scale can play a role in the standardization of perforation evaluation and treatment outcomes assessment. Laryngoscope, 133:1315–1320, 2023

AbstractObjectiveInvasive fungal sinusitis (IFS) in patients with active or recent COVID‐19 have been reported throughout the world. The primary purpose of the systematic review is to describe factors associated with IFS in patients with COVID‐19. The goal of the case series was to also characterize these factors in addition to evaluating the incidence of IFS at our institution after the onset of the pandemic.MethodsA systematic review using the preferred reporting in systematic reviews and meta‐analyses (PRISMA) framework identified publications of IFS cases associated with COVID‐19 (IFSAC). Search terms were “COVID‐19,” “invasive,” “fungal,” and “sinusitis.” IFS cases were evaluated for COVID‐19 status, fungal etiology, comorbidities, treatment, and outcome. A case series of patients at our center with IFS between December 1, 2018 to March 31, 2020 (“pre‐covid”) and April 1, 2020 to August 1, 2021 (“post‐covid”) was also performed with the above parameters.ResultsFourteen studies totaling 206 cases of IFSAC were identified. Most cases came from India (140/206, 68.0%), followed by Egypt (62/206, 30.1%), and North America (4/206, 1.9%). Diabetes was the most common comorbidity (151/206, 73.3%). Recent or prolonged steroid use was noted in 65.0% of cases (134/206). In our series, five pre‐covid and four post‐covid cases were identified. One had recent COVID‐19 infection. Acute myeloid leukemia was the most common pre‐covid comorbidity (3/5, 60.0%). Diabetes was the most frequent post‐covid comorbidity (2/4, 50.0%). Chronic steroid usage was noted in two pre‐covid and one post‐covid cases.ConclusionDiabetes and steroid use are common factors in reported cases of IFSAC. IFS incidence in our case series did not change appreciably after the onset of the pandemic.Level of Evidence: 4.

Objectives: Hereditary hemorrhagic telangiectasia (HHT) is a common inherited condition characterized by mucosal telangiectasias, recurrent epistaxis, and arteriovenous malformations. HHT results in detriment to quality of life. Morbidity and mortality result from severe anemia. Conventional interventions for HHT-related epistaxis include nasal packing, diathermy, lasers, coblation, microdebridement, bevacizumab (topical and systemic), as well as septodermoplasty and nasal closure. Sclerotherapy has been recently described in the literature as a novel approach to HHT-related epistaxis. We hypothesize that sclerotherapy is an effective treatment for HHT-related epistaxis and improves upon the current standard of care for this disease. Methods: A systematic review was conducted to study sclerotherapy for treating HHT-related epistaxis. Ovid MEDLINE, Ovid EMBASE, Scopus, and Web of Science were searched. Articles were evaluated and excluded according to PRISMA guidelines and reviewed by 2 authors. Reported variables included number of injections, months of follow up, changes in Epistaxis Severity Score, previous treatments used to control epistaxis, and post-injection side effects. Results: Seven studies with a total of 196 patients met inclusion criteria. Three studies reported significant improvement as measured by the Epistaxis Severity Score scale. One reported improvement through subjective patient surveys and others used the Bergler-Sadick scale to measure frequency and intensity of epistaxis. All studies reported improvement in HHT-related epistaxis. The lack of uniform reporting measures however precluded formal meta-analysis. Conclusions: Based on limited data, sclerotherapy appears to be effective for treating HHT-related epistaxis and offers promise for treating this recalcitrant condition. However, larger, prospective, multi-centered studies using universally validated instruments for epistaxis are needed to definitively evaluate outcomes from sclerotherapy.

AbstractIn the last two decades, the development of culture‐independent genomic techniques has facilitated an increased appreciation of the microbiota‐immunity interactions and their role in a multitude of chronic inflammatory diseases such as chronic rhinosinusitis (CRS), asthma, inflammatory bowel disease and dermatitis. While the pathologic role of bacteria in chronic inflammatory diseases is generally accepted, the understanding of the role of fungi remains controversial. Chronic rhinosinusitis, specifically the phenotype linked to nasal polyps, represents a spectrum of chronic inflammatory diseases typically characterized by a type 2 immune response. Studies on the microbiota within sinus cavities from healthy and diseased patients have focused on the bacterial community, mainly highlighting the loss of diversity associated with sinus inflammation. Within the various CRS with nasal polyps (CRSwNP) phenotypes, allergic fungal rhinosinusitis presents an opportunity to investigate the role of fungi in chronic type 2 immune responses as well as the antifungal immune pathways designed to prevent invasive fungal diseases. In this review, we examine the spectrum of fungi‐associated sinus diseases highlighting the interaction between fungal species and host immune status on disease presentation. With a focus on fungi and type 2 immune response, we highlight the current knowledge and its limitations of the sinus mycobiota along with cellular interactions and activated molecular pathways linked to fungi.

BackgroundSinusitis is a common outpatient diagnosis made by physicians and is a reason for referral to otolaryngologists. A foundation in basic sinonasal anatomy is critical in understanding sinus pathophysiology and avoiding complications. Our objective in this study was to develop and to validate a self‐directed surgical anatomy video for medical students.MethodsTwo multimedia videos were developed highlighting sinonasal anatomy. In Video 1 we included audio narration and radiologic imaging. Video 2 incorporated highlighted images from a sinus surgery video. An assessment was developed to test sinonasal anatomy landmarks, spatial recognition of structures, and their clinical relevance. An expert panel of rhinologists scored face and content validity of the curriculum videos and assessment. Factor analysis was used to separate questions into face and content validity domains, and a one‐sample t test was performed.ResultsThe panel scored face validity (Videos 1 and 2: 4.4/5) and content validity (Video 1: 4.5/5, 0.83; Video 2: 4.3/5, 0.75) significantly higher than a neutral response. There were no statistical differences for face or content validity between videos. The assessment was rated suitable (29%) or very suitable (57%) for testing basic sinonasal surgical anatomy, and the majority (71%) of respondents agreed (14%) or strongly agreed (57%) that the assessment thoroughly covered the sinus anatomy content with which medical students should be familiar.ConclusionWe have developed two videos and an assessment that highlight and test sinonasal anatomy. Future studies will aim to identify whether the use of a self‐directed video curriculum improves sinonasal anatomy awareness and whether incorporation of surgical endoscopic videos augments training.

Objective To provide a comprehensive state‐of‐the‐art review of the emerging role of urine leukotriene E4 (uLTE4) as a biomarker in the diagnosis of chronic rhinosinusitis (CRS), aspirin‐exacerbated respiratory disease (AERD), and asthma. Data Sources Ovid MEDLINE(R), Ovid EMBASE, Ovid Cochrane Central Register of Controlled Trials, Ovid Cochrane Database of Systematic Reviews, and Scopus. Review Methods A state‐of‐the‐art review was performed investigating the role of uLTE4 as a diagnostic biomarker, predictor of disease severity, and potential marker of selected therapeutic efficacy. Conclusions uLTE4 has been shown to be a reliable and clinically relevant biomarker for CRS, AERD, and asthma. uLTE4 is helpful in ongoing efforts to better endotype patients with CRS and to predict disease severity. Implications for Practice Aside from being a diagnostic biomarker, uLTE4 is also able to differentiate aspirin‐tolerant patients from patients with AERD and has been associated with objective disease severity in patients with CRS with nasal polyposis. uLTE4 levels have also been shown to predict response to medical therapy, particularly leukotriene‐modifying agents.

Objectives: Topical vasoconstrictors and intravenous tranexamic acid (IV TXA) are safe and efficacious to decrease bleeding and improve the surgical field during endoscopic sinus surgery (ESS). The purpose of this study was to investigate practice patterns, awareness of clinical evidence, and comfort levels among anesthesia providers regarding these hemostatic agents for ESS. Methods: A total of 767 attending anesthesiologists, residents, and certified registered nurse anesthetists (CRNAs) at 5 United States academic centers were invited to participate in a survey regarding their experience with IV TXA and 3 topical vasoconstrictor medications (oxymetazoline, epinephrine, and cocaine) during ESS. Results: 330 (47%) anesthesia providers responded to the electronic survey. 113 (97%) residents, 92 (83%) CRNAs, and 52 (68%) attendings managed 5 or fewer ESS cases per month. Two-thirds of providers had not reviewed efficacy or safety literature for these hemostatic agents. Oxymetazoline was perceived safest, followed by epinephrine, IV TXA, and cocaine. Respondents considered potential side effects over surgical field visibility when selecting agents. The majority of providers had no formal training on these agents for ESS, but indicated interest in educational opportunities. Conclusion: Many anesthesia providers are unfamiliar with safety and efficacy literature regarding agents used to improve hemostasis for ESS, highlighting a need for development of relevant educational resources. Rhinologic surgeons have an opportunity to communicate with anesthesia colleagues on the use of hemostatic agents to improve the surgical field during ESS.

ObjectiveReporting patient symptoms due to nasal septal perforation (NSP) has been hindered by the lack of a validated disease‐specific symptom score. The purpose of this study was to develop and validate an instrument for assessing patient‐reported symptoms related to NSP.Study DesignValidation study.SettingA tertiary care center.MethodsThe Nasal Obstruction Symptom Evaluation (NOSE) scale was used as an initial construct to which 7 nonobstruction questions were added to measure septal perforation symptoms. The proposed NOSE‐Perf instrument was distributed to consecutive patients evaluated for NSP, those with nasal obstruction without NSP, and a control group without rhinologic complaints. Questionnaires were redistributed to the subgroup with NSP prior to treatment of the perforation.ResultsThe study instrument was completed by 31 patients with NSP, 17 with only nasal obstruction, and 22 without rhinologic complaint. Internal consistency was high throughout the entire instrument (Cronbach α = 0.935; 95% CI, 0.905‐0.954). Test‐retest reliability was demonstrated by very strong correlation between questionnaires completed by the same patient at least 1 week apart (r = 0.898, P <. 001). Discriminant validity was confirmed via a receiver operating characteristic (P <. 001, area under the curve = 0.700). The NOSE‐Perf scale was able to distinguish among all 3 study groups (P <. 001) and between NSP and nasal obstruction (P =. 024). When used alone, the NOSE scale could not discriminate between NSP and nasal obstruction (P =. 545).ConclusionsThe NOSE‐Perf scale is a validated and reliable clinical assessment tool that can be applied to adult patients with NSP.

BackgroundAsthma and some chronic rhinosinusitis (CRS) subtypes are mediated by similar pathophysiologic mechanisms. The purpose of this study was to evaluate the effects of biologic therapy for asthma on co‐existent CRS in the “real‐world” setting.MethodsA review of electronic health records (2016‐2019) at Mayo Clinic was conducted to identify asthma patients treated with biologics who had co‐existent CRS. Matched‐pair analyses compared pretherapy and posttherapy Lund‐Mackay computed tomography (CT) scores and 22‐item Sino‐Nasal Outcome Test (SNOT‐22) scores. Performance of endoscopic sinus surgery (ESS) after initiating biologics was studied.ResultsWe identified 247 patients who received anti‐asthma biologic therapy and had co‐existent CRS. Of these, 181 patients (73.3%) had CRS with nasal polyposis (CRSwNP) and 66 (26.7%) had CRS without nasal polyposis (CRSsNP). The biologics utilized were omalizumab (51.0%), mepolizumab (46.6%), benralizumab (10.5%), reslizumab (1.6%), and dupilumab (2.4%). Anti‐interleukin‐5 (anti‐IL‐5) intervention was associated with significant improvement in CT scores (CRS overall, CRSwNP subgroup, CRSsNP subgroup) and SNOT‐22 scores (CRS overall, CRSwNP subgroup). Patients on omalizumab had a decrease in CT scores, but not SNOT‐22 scores. ESS was performed in 206 patients (84.1%); 55 (22.3%) underwent surgery post–biologic intervention (anti‐IL‐5: 16.5%; omalizumab 27.8% of patients).ConclusionAnti‐IL‐5 agents were associated with improved CT and SNOT‐22 scores in the overall CRS group and in CRSwNP subgroup; CRSsNP patients showed improved CT scores only. Omalizumab improved CT but not SNOT‐22 scores. ESS was performed in 22% of patients after initiating biologics. These real‐world results may influence future trial designs and clinical applications of biologics for CRS. ©2021 ARSAAOA, LLC.
