IMPORTANCE: Single sensory impairment is associated with reduced functional resilience and increased mortality, though the effects of multiple sensory deficits are not known. OBJECTIVE: To investigate longitudinal associations of the type, severity, and number of sensory impairments with physical function trajectories and mortality in older adults. DESIGN, SETTING, AND PARTICIPANTS: This retrospective analysis of a longitudinal cohort study, the Health, Aging, and Body Composition (Health ABC) study, incorporated data from April 1997 to July 2013, featuring a 16-year follow-up with annual examinations and questionnaires. The cohort comprised 3075 men and women, aged 70 to 79 years at baseline, residing in Memphis, Tennessee, and Pittsburgh, Pennsylvania. All participants with complete sensory testing and covariate data at analytical baseline (year 5, 2002) were included. The data were analyzed September 1, 2022. EXPOSURES: Visual, olfactory, auditory, and touch sensory functions were assessed between 2000 and 2002. MAIN OUTCOMES: The main outcomes included physical functioning trajectories and mortality risk. Physical function was assessed longitudinally using the Health ABC physical performance battery (HABCPPB). RESULTS: A total of 1825 individuals (mean [SD] age, 77.4 [3.2] years; 957 [52%] female) were included in this study. Multivariable analysis of HABCPPB decline indicated that having 1 sensory impairment (β estimate, −0.01 [95% CI, −0.02 to −0.001]); 2 sensory impairments (β estimate, −0.01 [95% CI, −0.02 to −0.01]); 3 sensory impairments (β estimate, −0.03 [95% CI, −0.04 to −0.02]); or 4 sensory impairments (β estimate, −0.04 [95% CI, −0.05,−0.03]) was significantly associated with a steeper HABCPPB score decline in a dose-dependent manner. Adjusted Cox proportional hazards models indicated that having 1 sensory impairment (hazard ratio [HR], 1.35 [95% CI, 1.01-1.81]), 2 sensory impairments (HR, 1.58 [95% CI, 1.19-2.11]), 3 sensory impairments (HR, 1.79 [95% CI, 1.33-2.42]), or 4 sensory impairments (HR, 1.97 [95% CI, 1.39-2.79]) was significantly associated with increased mortality risk in a similarly dose-dependent manner. CONCLUSION: In this retrospective cohort study, the degree and number of multiple sensory impairments were associated with worse physical functioning and increased mortality risk. These findings represent an opportunity for further investigation into the value of screening, prevention, and treatment of sensory impairments to reduce morbidity and mortality in older adults.

Background Studies evaluating health-related quality of life (HRQOL) in patients with hereditary hemorrhagic telangiectasia (HHT) have expanded rapidly in the past decade. These studies have evaluated QOL aspects ranging from the general QOL for patients living with HHT to intervention-specific outcomes. However, few tools have been fully validated across the spectrum of disease manifestations and interventions in HHT.Objective In this scoping review, we aim to map the literature on HHT-QOL metrics, identify gaps, inform future QOL research, and facilitate future metric development.Methods We analyzed articles in English that assessed at least 1 measure of general HRQOL, including physical health, mental health, social health, or intervention-specific QOL in patients with HHT. Searches across 2 bibliographic databases (PubMed and Scopus) yielded 186 articles after duplicates were removed. Sixty-three studies met eligibility criteria: 22 prospective studies (34.9%), 20 retrospective studies (31.7%), 12cross-sectional studies (17.5%), 6 randomized controlled trials or secondary analyses of a randomized controlled trials (9.5%), 2 qualitative studies (3.2%), and 1 case-control study (1.6%). Two additional studies—1 prospective and 1 cross-sectional study—were identified at the October 2022 14th International HHT Conference and included, making a total of 65 studies.Results The 65eligible studies used 30QOL instruments. Twenty studies characterized baseline HRQOL, and 45studies evaluated QOL before and after treatment. Of those 45 studies, 37evaluated HRQOL before and after therapies targeting epistaxis and nasal symptoms, 4 targeted therapies for liver arteriovenous malformations and high-output heart failure, 3 evaluated therapies for both epistaxis and gastrointestinal bleeding, and 1 evaluated treatment targeting gastrointestinal bleeding alone.Conclusions Comparison of results across studies remains challenging given the heterogeneity in outcomes measures. Further development of HHT-specific patient-reported outcomes instruments that capture the global illness experience of HHT is needed.

IMPORTANCE: Olfactory dysfunction (OD) is increasingly recognized as a robust marker of frailty and mortality. Despite broad recognition of frailty as a critical component of head and neck cancer (HNC) care, there is no standardized frailty assessment. OBJECTIVE: To assess the prevalence of OD and its association with frailty and postoperative outcomes in HNC. DESIGN, SETTING, AND PARTICIPANTS: In this prospective cohort study with enrollment between February 17, 2021, to September 29, 2021, at a tertiary academic medical center, 85 eligible adult patients with primary, treatment-naive HNC of mucosal or cutaneous origin were included. Patients with a history of COVID-19, neurocognitive, or primary smell/taste disorders were excluded. EXPOSURES: Prospective olfactory assessments (self-reported, visual analog scale [VAS] and psychophysical, University of Pennsylvania Smell Identification Test [UPSIT]) with concurrent frailty assessment (Risk Analysis Index [RAI]) were used. Olfactory-specific quality of life (QOL) was examined with brief Questionnaire of Olfactory Disorders–Negative Statements (QOD-NS). MAIN OUTCOME(S) AND MEASURE(S): The primary outcome was the prevalence of OD as assessed by VAS (0-10, no to normal smell) and UPSIT (0-40, higher scores reflect better olfaction) and its association with frailty (RAI, 0-81, higher scores indicate greater frailty). For surgical patients, secondary outcomes were associations between OD and postoperative length of stay (LOS), 30-day postoperative outcomes, and QOD-NS (0-21, higher scores indicate worse QOL). RESULTS: Among 51 patients with HNC (mean [SD] age, 63 [10] years; 39 [77%] male participants; 41 [80%] White participants), 24 (47%) were frail, and 4 (8%) were very frail. Despite median (IQR) self-reported olfaction by VAS of 9 (8-10), 30 (59%) patients demonstrated measured OD with psychophysical testing. No meaningful association was found between self-reported and psychophysical testing (Hodges-Lehmann, <0.001; 95% CI, −2 to 1); a total of 46 (90%) patients did not report decreased olfaction-specific QOL. Median UPSIT scores were lower in frail patients (Hodges-Lehmann, 6; 95% CI, 2-12). Multivariate modeling demonstrated severe microsmia/anosmia was associated with 1.75 (95% CI, 1.09-2.80) times odds of being frail/very frail and approximately 3 days increased LOS (β, 2.96; 95% CI, 0.29-5.62). CONCLUSIONS AND RELEVANCE: Although patients with HNC are unaware of olfactory changes, OD is common and may serve as a bellwether of frailty. In this prospective cohort study, a dose-dependent association was demonstrated between increasing degrees of OD and frailty, and the potential utility of olfaction was highlighted as a touchstone in the assessment of HNC frailty.

Purpose: Cushing Syndrome (CS) is a rare endocrine disorder associated with physical and mental symptoms that can drastically affect quality of life (QoL). This study characterizes QoL in patients with CS, describes their treatment experiences, and identifies patient subsets associated with decreased QoL or shared impressions of treatment. Methods: A 136-question survey addressing QoL factors and treatment experiences was completed by adult patients with CS from the Cushing Support and Research Foundation. Patient demographics, tumor characteristics, and treatment information were collected. Bivariate analyses were conducted to determine if patients’ symptoms or treatment experiences were significantly associated with demographics or other variables. Results: A total of 178 patients, predominantly female (94%) with mean age 53 years, completed the survey. Anxiety and/or depression (n= 163, 94%), loss of physical strength (n= 164, 93%), loneliness (n= 156, 90%), fatigue from treatment (n= 142, 89%), memory loss (n= 153, 88%), insomnia (n= 144, 83%), and pain (n= 141, 83%) were symptoms most commonly experienced by respondents. Patients experiencing delay of diagnosis >10 years were more likely to have suicidal thoughts (p= 0.002). Younger patients were more likely to express concerns about hair loss (p= 0.007), loneliness (p= 0.025), pain (p= 0.004), or the impact of CS on their marriage (p= 0.039) or children (p= 0.024). Conclusion: This survey demonstrates CS impacts patients across many dimensions, emphasizing the need for holistic support. We identified patient subsets in which QoL may be improved with additional patient resources or provider attention.

IMPORTANCE: Traumatic brain injury has been associated with short-term olfactory dysfunction, but the association of number of prior head injuries and head injury severity with both subjective and objective long-term olfactory function is less clear. OBJECTIVE: To investigate the associations of prior head injury, number of prior head injuries, and head injury severity with subjective and psychophysical (objective) olfactory function in older adults and to examine concordance between subjective and objective olfactory function among individuals with and without head injury. DESIGN, SETTING, AND PARTICIPANTS: This prospective cohort study included 5951 participants who attended Atherosclerosis Risk in Communities (ARIC) Study visit 5 (2011 through 2013). Data analysis was performed between November 2021 and May 2022. EXPOSURES: Head injury was defined by self-report and International Classification of Diseases codes. MAIN OUTCOMES AND MEASURES: Self-reported subjective olfactory dysfunction was assessed by the question, “Do you suffer from smell loss or a significantly decreased sense of smell?” Objective olfactory performance was assessed using the 12-item Sniffin’ Sticks odor identification test. RESULTS: Overall, the 5951 participants were a mean (SD) age of 75.6 (5.2) years, 3501 (58.8%) were female, 1356 (22.8%) were of Black race, and 1666 (28.0%) had a history of head injury. Participants with prior head injury were more likely than individuals without prior head injury to report subjective olfactory dysfunction (24% vs 20%; difference, 4%; 95% CI, 1% to 6%) and have objective anosmia (15% vs 13%; difference, 2%; 95% CI, 0.1% to 4%) but had lower concordance between subjective and objective assessment (72% vs 77%; difference, −5%; 95% CI, −8% to −3%). In logistic regression models adjusted for sociodemographics and medical comorbidities including cognitive status, participants with a history of prior head injury, particularly individuals with 2 or more prior head injuries and more severe head injuries, were more likely to self-report subjective olfactory dysfunction and were more likely to be found to have objective anosmia compared with participants with no history of head injury. CONCLUSIONS AND RELEVANCE: Findings of this cohort study provide evidence supporting the association between head injury and olfactory dysfunction, particularly among individuals who experienced multiple prior head injuries and among individuals with more severe head injury. The findings also suggest that individuals with prior head injury were more likely to both under–self-report and over–self-report deficits compared with objective olfactory testing; therefore, it may be important to consider objective olfactory testing in this patient population.

Background Chronic rhinosinusitis (CRS) presents with broad and systemic manifestations, including impaired sleep; however, the impact of CRS treatments upon sleep is unknown.Objective To establish the effect of medical or surgical CRS treatment on subjective and objective sleep metrics for patients not previously diagnosed with sleep apnea.Methods Review of PubMed, Scopus, Web of Science, and the Cochrane Library was performed from the databases’ date of inception through August 13, 2020, for studies evaluating the effect of CRS treatment on sleep quality. All studies reporting on subjective and objective sleep parameters for patients with CRS, with completed pre- and posttreatment data were included. Studies composed of patients with diagnosed sleep apnea were excluded.Results Sixteen unique studies reporting data on a total of 1770 patients (mean age, 50.6 ± 15.6 (n = 1675) years) following treatment for CRS were included. Patient-reported outcome measures, Epworth Sleepiness Scale, Pittsburgh Sleep Quality Index, and Fatigue Severity Scale, demonstrated mean posttreatment differences of −2.8 (95% CI: −4.9 to −0.7), −2.4 (95% CI: −3.7 to −1.2), and −1.2 (95% CI: −1.6 to −0.7), respectively. The SNOT-22 and its sleep domain demonstrated a mean posttreatment difference of −23.5 (95% CI: −31.7 to −15.3) and −5.4 (95% CI: −6.8 to −4.0), respectively. EpSS, FSS and SNOT-22 exceeded their respective reported MCID values. Objective findings did not significantly change with treatment; mean difference: AHI: 0.7 (95% CI: −1.5 to 2.9), oxygen nadir: 0.3 (95% CI: −0.4 to 0.9).Conclusions Treatment of CRS may lead to clinically meaningful reduction in disease burden and improvements in both overall sleep quality and patient-reported fatigue. Despite clinically meaningful quality of life improvements, objective sleep parameters did not demonstrate corresponding posttreatment improvements.

Purpose: Patients with chemosensory dysfunction experience significant quality of life disruptions, including reduced enjoyment of eating. While chemosensory dysfunction has been associated with eating disorders, the relationship is poorly understood. This systematic review aims to characterize psychophysical gustation and olfaction in patients with eating disorders. Methods: Systematic review of investigations assessing psychophysical chemosensory function in patients with organic eating disorders. Results: 26 studies were included. Five studies assessed both chemosenses, while 12 and 9 assessed exclusively gustation or olfaction, respectively. In total, 779 patients were included [72.4% anorexia nervosa (AN), 26.7% bulimia nervosa (BN), 0.8% combined AN/BN]. Patients with eating disorders experienced rates of hypogeusia up to 87% in AN and 84.6% in BN. There was evidence for alterations in psychophysical olfaction, but orientation of trends were less clear. Chemosensory dysfunction was more evident in AN patients. Treatment correlated with improved chemosensory function. Conclusions: Despite heterogeneity in study methodology and results, this review demonstrates that patients with eating disorders experience some degree of chemosensory dysfunction, particularly in gustation. This symptomatology overlaps with those experienced by patients with other causes of chemosensory impairment. These findings suggest potential broad psychosocial, dietary, and mental health implications in patient populations experiencing chemosensory dysfunction. Level of evidence: Level II.

Background Evidence suggests chemosensory dysfunction (CSD) patients have altered diet, but population-level evidence assessing diet quality in CSD patients is lacking.Objective We examined the association between CSD and diet quality in a representative sample of United States adults.Methods This cross-sectional study included 2831 adults aged greater than 40 years from the 2013-2014 National Health and Nutrition Examination Survey who completed the taste/smell questionnaire and examination. Mean nutrient intake in subjects with self-reported olfactory/gustatory dysfunction (sOD/sGD) and measured olfactory/gustatory dysfunction (mOD/mGD) were compared to those without CSD using univariate Wilcoxon rank-sum tests. The Healthy Eating Index (HEI), a validated measure of diet quality, was calculated. The proportion of subjects with CSD with bottom-quartile HEI was compared to those without CSD using multivariate logistic regression, adjusting for demographic and socioeconomic covariates.Results The population-weighted prevalence of sOD, sGD, mOD, and mGD was 20.1%, 14.4%, 15.9% and 25.6%, respectively. Subjects with mOD had lower mean intake of total calories, total fat, protein, sodium, and potassium compared to normal subjects (1873.4 ± 49.6 vs 2010.2 ± 24.2 kcal, 72.3 ± 2.7 vs 78.6 ± 1.0 gm, 74.0 ± 2.5 vs 80.4 ± 0.6 gm, 3122 ± 97.2 vs 3353.2 ± 37.0 mg, 2509.8 ± 69.8 vs 2684.7 ± 26.1 mg, P< 0.05 respectively). When controlling for sociodemographic factors and comorbidities, subjects with sOD were more likely to have bottom-quartile HEI compared to normal subjects (OR 1.33, 95% CI 1.04–1.70).Conclusions This population-level study suggests an association between poor diet quality and variation in dietary intake in patients with CSD, which warrants further investigation and suggests the possible need for nutritional counseling for CSD patients.

Background The management of paranasal sinus and nasal cavity malignancies has evolved significantly with the development of advanced endoscopic techniques and improvements in adjuvant therapy. We sought to characterize both disease-specific survival (DSS) and 5-year conditional disease-specific survival (CDSS, the change in life expectancy with increasing survivorship) for sinus malignancies diagnosed before and after the year 2000.Methods Patients diagnosed with sinus and nasal cavity cancer between 1973-2015 were extracted from the Surveillance, Epidemiology, End Results (SEER) registry. Kaplan-Meier analysis for DSS was stratified by year of diagnosis before and after 2000. Cox-proportional hazards models of DSS controlling for stage, age, and year of diagnosis were generated. CDSS was calculated using Cox-regression models stratified by stage.Results We analyzed 10,535 patients. Diagnosis after the year 2000 was independently associated with improved DSS (HR:0.81, 95% CI: 0.75-0.87, P< .001) after controlling for age and stage. After stratifying by stage, diagnosis after year 2000 was associated with improved DSS for localized (HR:0.71, 0.59-0.86, P< .001) malignancies, regional (HR: 0.86, 0.78-0.94, P= .001) and distant malignancies (HR 0.74, 0.63-0.87, P< .001). CDSS improved with increasing survivorship for all stages of sinus and nasal cavity cancer, and those diagnosed after 2000 had improved CDSS compared to those diagnosed before 2000. Descriptively, the association of year of diagnosis with CDSS diminished with increasing survivorship for localized cancers, but was consistent for other stages.Conclusion For paranasal sinus and nasal cavity malignancies, year of diagnosis independently influences both DSS and CDSS. Improved survival is likely due to advances in both surgical and adjuvant treatments. To our knowledge, this study is the first to examine CDSS for these malignancies.

Hereditary hemorrhagic telangiectasia is an autosomal dominant disorder that causes multisystem vascular malformations, and early diagnosis, screening, and multidisciplinary treatment are important to decrease complications and improve quality of life.

As endoscopic endonasal skull base surgery (EESBS) for sellar pathology has become routine, there is increasing awareness of quality-of-life (QOL) outcomes related to this approach. Similarly, there is a growing interest in postoperative chemosensory function, with notable emphasis on olfaction and the corresponding psychosocial implications of olfactory dysfunction. Meanwhile, there has been minimal direct investigation into gustatory outcomes, and the association between these 2 chemosensory functions remains poorly understood.

Background Olfactory dysfunction (OD) has been reported to impact social interactions. However, the relationship between OD and loneliness has received little attention. The purpose of this study was to determine the association between OD and loneliness, controlling for patient factors.Methods Subjects without otolaryngic complaints were enrolled and olfactory function was assessed using: Sniffin’ Sticks test to measure threshold, discrimination and identification (TDI), Questionnaire of Olfactory Disorders Negative Statements (QOD-NS) and 9 – item Olfactory-Visual Analogue Scale (VAS). Loneliness was assessed using the De Jong Gierveld (DJG) and University of California Los Angeles (UCLA) loneliness scales. Bivariate analysis was performed followed by regression analysis, controlling for confounders.Results In total, 221 subjects were included with a mean age of 50.5 years (range 20 to 93), 133 (60.2%) females and 161 (72.9%) white. Mean TDI score was 29.3 (7.0) and 49.5% of the cohort was dysosmic. Using DJG, 36.4% of the cohort were classified as lonely, whereas 35.0% were lonely using UCLA. Olfactory measures were significantly associated with DJG, including TDI (β= −0.03, p = 0.050), olfactory discrimination (β= −0.111, p = 0.005), QOD-NS (β= 0.058, p < 0.001) and olfactory-VAS (β= 0.032, p < 0.001). UCLA scores were significantly associated with QOD-NS (PR 1.061 [CI 1.018–1.107], p = 0.005) and olfactory-VAS scores (PR 1.027, [CI 1.007–1.049], p = 0.009). After controlling for confounders, the association between DJG and olfactory discrimination, as well as DJG and olfactory-VAS remained significant.Conclusions In this community-based sample of older adults, both OD and loneliness were common. Those subjects with worse olfactory function were more likely to report loneliness. Further research is necessary to establish causality, as well as explore the role of depression.

Background Viral respiratory tract infections are associated with a significant burden of disease and represent one of the leading causes of mortality worldwide. The current Coronavirus Disease 2019 (COVID-19) pandemic highlights the devastating toll that respiratory viruses have on humanity and the desperate need to understand the biological characteristics that define them in order to develop efficacious treatments and vaccines. To date, Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) has infected nearly 600 times more people and resulted in 200 times more deaths relative to Severe Acute Respiratory Syndrome Coronavirus (SARS-CoV) and Middle Eastern Respiratory Syndrome Coronavirus (MERS-CoV) combined.Objective Through this review, we aim to summarize the key characteristics of respiratory viruses that hold global significance, with a focus on SARS-CoV-2. Our goal is to disseminate our current knowledge of these infectious agents to otolaryngologists, in particular rhinologists, practicing in the COVID-19 era.Methods The general and clinical characteristics of selected respiratory viruses along with available viral treatments and vaccines are reviewed.Results There has been significant progress in our understanding of the epidemiology and pathogenesis of various respiratory viruses. However, despite the advancement in knowledge, efficacious vaccines and antiviral treatments remain elusive for most respiratory viruses. The dire need for these scientific discoveries is highlighted by the recent COVID-19 pandemic, which has prompted investigators worldwide to conduct clinical trials at an accelerated timeline in an effort to reduce the morbidity and mortality associated with SARS-CoV-2 infection. Rhinologists will continue to remain on the front-lines of pandemics associated with respiratory viruses.Conclusion In light of these unprecedented times, the need to understand the nuances of these viral respiratory pathogens, especially SARS-CoV-2, cannot be overemphasized. This knowledge base is of particular importance to otolaryngologists, whose expertise in the upper airway coincides with the anatomic tropism of these infectious agents.

Background Allergic fungal rhinosinusitis (AFRS) is disproportionately identified in patients of low socioeconomic status living in warm, humid climates, and is thought to occur in response to environmental fungal species.Objective We hypothesized that micro-geographic differences in fungal exposure contribute to the pathogenesis of AFRS, and compared home fungal exposure of patients with AFRS to normative data and controls.Methods Comprehensive prospective enrollment and data capture was completed in 70 patients. Patients with AFRS were compared to a control population with chronic rhinosinusitis with nasal polyposis (CRSwNP) and comorbid atopy. Comprehensive demographics, 22-item sino-nasal outcomes test (SNOT-22) questionnaires, and endoscopy scores were compiled. Using a test strip collection system, a home fungal assessment was completed for each patient, along with detailed questions related to home condition.Results Patients with AFRS were more likely to be younger (p<.001), African American (p<.001), from a lower income bracket (p < .012), and less likely to own their home (p < .001). There were no differences in prior surgeries (p=.432), endoscopy scores (p = .409) or SNOT-22 scores (p = .110) between the groups. There were no differences in overall fungal counts between patients with AFRS and controls (p = .981). AFRS patients had a higher prevalence of Basidiospores than controls (p = .034).Conclusion This study failed to detect differences in total home fungal exposure levels between those with AFRS and atopic CRSwNP, despite differences in socioeconomic status. This suggests that absolute fungal levels may not be the primary driver in development of AFRS, or that the fungal detection strategies utilized were not representative of patients’ overall fungal exposure.

Background Olfactory dysfunction (OD) is common, affecting an estimated 13 million adults in the United States. Prior studies may underestimate OD prevalence due to use of brief smell identification tests or age-adjusted cutoff values, which concede that it is acceptable for older people to have a decreased sense of smell.Objective To determine OD prevalence in the healthy community when the goal and expectation is ideal olfactory function, rather than age-based population norms. Secondary goals were to explore factors associated with OD.Methods Subjects without otolaryngic complaints were recruited from the community surrounding the Medical University of South Carolina. Olfactory-specific information was collected, and olfactory function was assessed using the Sniffin’ Sticks test (Burghardt, Wedel, Germany) to measure threshold, discrimination, and identification (TDI). OD was defined as a TDI score < 31. Bivariate analysis and linear regression were used to determine factors associated with OD.Results In total, 176 subjects were included with mean age of 52 years (range: 20–93), 111 (63%) female, and 127 (72%) white. Mean TDI score was 28.8 (6.9) and OD was present in 94 (53%) subjects. Multivariate linear regression revealed that TDI decreased an average of 1 point every 5 years. TDI was also associated with Mini-Mental Status Examination (MMSE) score, asthma, and gastroesophageal reflux disease. Threshold was associated with age, heart problems, and gastroesophageal reflux disease. Discrimination was associated with age and MMSE scores. Identification was associated with age, heart problems, and anxiety.Conclusions In a community-based sample, OD affects greater than 50% of subjects. Aging impacts all aspects of olfaction, while the effects of factors such as asthma, MMSE scores, gastroesophageal reflux disease, heart problems, and anxiety may only be evident in specific olfactory subtests.

Olfactory dysfunction (OD) is one of the cardinal symptoms of chronic rhinosinusitis (CRS), and its prevalence ranges from 60% to 80% in patients with CRS. It is much more common in CRS with nasal polyposis patients compared to CRS without nasal polyposis. Decreased olfactory function is associated with significant decreases in patient-reported quality of life (QOL), and notably, depression and the enjoyment of food. Objective measures can help detail the degree of OD, whereas subjective measures can help to determine in the impact on patient. There is variable treatment response to OD with both medical and surgical therapies.

The treatment paradigm for the management of chronic rhinosinusitis with nasal polyposis (CRSwNP) is currently undergoing a rapid evolution with the development of monoclonal antibody therapies targeted at type 2 inflammatory pathways. The use of these biologic therapies in asthmatic patients, and more recently, patients with CRSwNP has produced promising results, especially for patients with severe disease. Many questions regarding the appropriate timing of these medications, whether or not these new treatment strategies should be used as a monotherapy or in conjunction with traditional therapies such as sinus surgery, the role of appropriate phenotyping, and identification of biomarkers, remain unanswered. We herein present a case of a patient with severe eosinophilic asthma and comorbid CRSwNP who failed to achieve control of his respiratory symptomology and ultimately progressed to sinus surgery despite treatment with an anti-interleukin 5 monoclonal antibody therapy (mepolizumab). Consideration is given to the mechanistic underpinnings of the reported patient's failure. This case highlights the need for further understanding of the optimal usage of these novel therapeutics in the management of CRSwNP and in the need to better understand the pathophysiology of CRSwNP.

Background Intranasal trigeminal function is important in detecting environmental stimuli. The impact of age-associated chemosensory dysfunction upon taste and olfaction is well described, but an understanding of trigeminal loss (chemesthesis) is lacking.Objective The goal of this study was to characterize trigeminal function in a cohort of older adults and explore potential impacts.Methods Twenty-eight participants over 50 years of age were recruited from the community as part of an aging cohort study. This nested cohort completed chemosensory questionnaires, patient-reported outcome measures (PROMs), and psychophysical testing for taste (taste strips), olfaction (Sniffin’ Sticks), and trigeminal function (eucalyptol lateralization). Data were analyzed for associations between trigeminal function, olfactory, and taste psychophysical performance, patient-reported metrics, and demographic risk factors.Results Patient-reported trigeminal impairment is less severe than other chemosensory loss, with mean visual analog scores (VAS, rated 0-100 from least to most severe) for smell (32.9 ± 34.2), taste (20.6 ± 28.4), and trigeminal sensation (9.5 ± 12.8). Despite low VAS scores, psychophysical trigeminal dysfunction was present in 10 (35.7%) subjects. Psychophysical olfactory and taste dysfunction were present in 16 (57.1%) and eight (28.6%) participants respectively. Hypercholesterolemia was associated with psychophysical trigeminal dysfunction (mean lateralization performance in hypercholesterolemia 57.7% ± 17.1 vs. 74.1% ± 10.4, p= .008).Conclusion Intranasal trigeminal impairment is present in nearly one-third of aging adults when assessed by psychophysical methods but is under-recognized. Hyperlipidemia may be associated with trigeminal impairment. Future inquiries should better characterize these findings in larger and prospective cohorts.

NSAID-Exacerbated Respiratory Disease (NSAID-ERD) presents a significant challenge in clinical management, owing to recalcitrant disease with accompanying profound impacts on patient quality of life. Though asthma represents a significant component of this disease, quality of life disruptions are driven primarily by recalcitrant sinonasal complaints, olfactory dysfunction, and the associated psychosocial and dietary implications. This review delves into specific quality of life metrics used to assess NSAID-ERD and the associated healthcare burden and financial implications of this disease, offering insights into the comparative challenges in chronic rhinosinusitis with nasal polyps (CRSwNP) where available. The article reviews the associated costs and cost-effectiveness of NSAID-ERD-directed therapies, including endoscopic sinus surgery, aspirin desensitization, and biologic therapy. While some of these emerging treatment approaches show promise, they also present numerous unanswered questions, reflecting the dynamic nature of this field. As the landscape of NSAID-ERD management continues to evolve, this review provides insights into the challenges faced by clinicians and underscores the need for further research to optimize patient care and quality of life outcomes.

Background Allergic fungal rhinosinusitis (AFRS) is characterized by higher revision endoscopic sinus surgery (ESS) rates and unique radiographic features when compared to chronic rhinosinusitis with nasal polyposis (CRSwNP) or chronic rhinosinusitis without nasal polyposis (CRSsNP).Objective We hypothesized that an increased frequency of concha bullosa in AFRS or other radiographic nuances might allow for accumulation of allergic mucin and contribute to increased ESS revision rates.Methods A retrospective cohort study was performed. Patient diagnosis (AFRS, CRSwNP, and CRSsNP), basic demographics, and prior ESS rates were collected.Results A total of 210 consecutive patients were included (AFRS = 70, CRSwNP = 70, and CRSsNP = 70). Pediatric AFRS patients had more unilateral disease (38.1% vs 4.4%; P= .007) and anterior ethmoid skull base erosion (23.8% vs 6.7%; P= .047) than adult AFRS patients. AFRS patients were more likely to be younger (24.9 ± 10.1 years vs 45.6 ± 14.4 years vs 48.7 ± 18.2 years; P< .001), African American (70% vs 14.3% vs 11.4%; P< .001), and have undergone prior ESS (54.3% vs 45.7% vs 31.4%; P= .02) than CRSwNP or CRSsNP patients. Concha bullosa were more prevalent in AFRS patients than CRSwNP or CRSsNP patients across the population (42.9%, 18.6%, and 14.3%; P< .001) and in the setting of no previous surgery (53.1%, 31.6%, and 16.7%; P< .001).Conclusion In this cohort, pediatric AFRS patients had more unilateral disease and anterior ethmoid skull base erosion. Concha bullosa prevalence was significantly higher in AFRS as compared to those with CRSwNP or CRSsNP, despite prior ESS. Surgeons should consider concha bullosa as a potential anatomical subsite to harbor recurrent or residual disease.

Background Chronic rhinitis impacts 60 million Americans and is associated with significant costs for patients. Although medical treatments are first line, some patients require surgical intervention such as vidian or posterial nasal neurectomy. Previous reviews have investigated the role of surgical management in chronic rhinitis, but none have investigated a longstanding treatment with recent interest: cryotherapy.Objective To identify the safety, efficacy, and durability of treatment response of cryotherapy in treating chronic rhinitis.Methods A systematic literature review was performed to identify studies that investigated the utility of cryotherapy in chronic rhinitis. Only studies with the primary objective of assessing the efficacy of cryotherapy on chronic rhinitis were included. Patients were classified as allergic rhinitis, nonallergic rhinitis (vasomotor rhinitis), or mixed rhinitis using the original author’s criteria. Data were extracted regarding reported complications, treatment efficacy, and length of follow-up.Results A total of 110 abstracts were identified, of which 15 were included in this review. Epistaxis and nasal obstruction were commonly reported complications. No serious adverse events were reported. For obstructive symptoms, “reduced” symptoms were reported in 63.4% to 100% of patients. In regard to rhinorrhea, reports of reduced symptoms were experienced from 77% to 100% of patients. Seven studies used only patient-reported improvements without stratifying results based on symptom type; general improvements ranged from 67% to 100%. Nine studies noted symptom improvement in nonallergic cohorts ranging from 67% to 97.5% of patients. Four studies noted improvement in allergic cohorts ranging from 63.4% to 80% of patients. Two studies noted improvement in patients with mixed pictures ranging from 92.5% to 100%.Conclusions Although cryotherapy appears safe and efficacious, heterogeneous past investigations with low-quality evidence make strong, evidence-based recommendations difficult to make. Further study with validated metrics and controlled populations is certainly warranted and should be encouraged.

Background Retronasal olfaction is important in flavor detection and enjoyment. The ability to identify specific individual retronasal odors may play a role in quality of life for patients with chronic rhinosinusitis (CRS).Objective To identify patterns and improve understanding of retronasal identification of individual odors in CRS patients.Methods Patients diagnosed with CRS underwent retronasal and orthonasal (Sniffin’ Sticks) olfactory testing and taste testing (taste strips). Retronasal identification was tested with presentation of flavored powders on the posterior tongue. Retronasal identification for individual odors was compared with results of orthonasal and taste testing.Results Seventy participants were evaluated. Retronasal identification correlated with orthonasal identification and discrimination for most individual odors. Among all patients, cinnamon and apple were identified better retronasally and banana better orthonasally (P< .05). Anosmics identified retronasal orange, cinnamon, mushroom, coffee, smoked ham, peach, ginger, grape, and cheese more than would be expected by chance for a forced-choice paradigm with 3 distractor items (P< .05), and this was independent of objective taste function for most odors.Conclusion Retronasal and orthonasal identification of most odors correlate in CRS patients; however, patients with anosmia can still identify certain retronasal odors more often than expected. These odors do not appear to stimulate gustatory pathways and may involve trigeminal stimulation. Understanding preserved retronasal neural stimuli may allow providers to improve eating-related quality of life in these patients.

Background The cribriform plate (CP) is a common site of spontaneous cerebrospinal fluid (SCSF) leaks. Radiographic assessment of the anterior and lateral skull base has shown thinner bone in patients with SCSFs; however, prior assessment of the CP has required postmortem cadaver dissection.Objective To develop novel radiographic techniques to assess the anatomy of the CP.Methods Computed tomography (CT) scans were performed on cadaveric specimens. Bone density and anatomy of a predefined volume of interest of the posterior CP were assessed by two independent reviewers. CT assessment of olfactory foramina was also performed and validated using anatomic dissection of cadaver specimens.Results Interclass correlation coefficients (ICCs) for measuring the same volume of each CP was 0.96, confirming reproducible anatomic localization. Cadaver CPs had a mean Hounsfield units of 263, indicating a mix of bone and soft tissue, and ICC was 0.98, confirming reproducible radiographic measurements. Optimal CT estimates of bone composition of CPs averaged 85% (range 76% to 96%) compared to actual anatomic dissection which averaged 84% bone (range 74% to 91%, r= .690, P= .026).Conclusion Our novel, noninvasive CT method for assessing CP anatomy is reproducible and correlates with anatomic dissection assessing bone composition. The clinical implications of anatomic changes in the CP are an area for further study.

Objective: There is a paucity of literature discussing prognostic factors or comparing outcomes in eosinophilic angiocentric fibrosis (EAF). This review aims to analyze tumor and patient characteristics as possible prognostic markers and compare surgical approaches.Methods: Systematic literature review and case report analyzing available cases of EAF located within the paranasal sinuses.Results: The literature search yielded 39 articles meeting criteria for a total of 59 cases (including 1 from our institution). Median patient age was 46 years. The most common presenting symptoms were nasal obstruction (69%, n = 41) and change in external nasal appearance (39%, n = 32). The majority of cases (85%) were treated with surgical resection alone or in combination with medication. Of surgical patients, 62% underwent a complete resection with a recurrence rate of 20%. Median follow-up duration was 2 years. Endoscopic approach showed a significant positive correlation with complete resection (P= .045). Patient sex (P= .6), tumor location (range, P= .32-.98), lateral rhinotomy (P= .26), septoplasty (P= .84), and external rhinoplasty (P= .28) were not significantly correlated with total resection. Insufficient sample size precluded calculation of predictors of recurrence following surgery.Conclusion: This review suggests that an endoscopic approach to EAF tumor is a viable option, frequently yielding complete resection.

Background Pulmonary colonization with antibiotic-resistant organisms in patients with cystic fibrosis (CF) is often preceded by upper-airway infections. Although there is a well-described relationship between pulmonary respiratory viral infections and overall disease progression of CF, the pathogenicity of respiratory viral infections in the paranasal sinuses of patients with CF remains unknown. With recent advances in respiratory virus detection techniques, this study sought to detect the presence of respiratory viruses in the paranasal sinuses of patients with CF in comparison with healthy controls and to correlate the viral presence with clinical measures of sinonasal disease.Methods This prospective individual cohort study compared 24 patients with CF with 14 healthy controls. Basic demographics, clinical measures of disease and respiratory viral screens (commercial multiplex) obtained directly from the paranasal sinuses were compared between the two groups.Results Respiratory viruses were detected in 33% of patients with CF (8/24) compared with 0% of the healthy controls (0/14) (p = 0.017). Respiratory viruses were only detected during the winter months, and the most commonly identified were influenza A and human rhinovirus strains. There was no statistical difference in the 22-Item Sino-Nasal Outcome Test (SNOT-22) scores (p = 0.93) or modified Lund-Kennedy scores (p = 0.74) between patients with CF with a positive viral test and those without a positive result.Conclusions Respiratory viral detection is more commonly detected in the paranasal sinuses of patients with CF compared with healthy controls. Although respiratory viral presence did not correlate with a worse clinical severity of sinonasal disease, these findings may provide insight into the pathophysiology of CF and open new avenues for potential targeted therapy.

Background The role of viruses in chronic rhinosinusitis (CRS) is poorly understood. In part, this is secondary to difficulty in isolating viruses. Although traditional detection methods for respiratory viruses have had little clinical utility, modern viral screening techniques that use molecular sequencing are now both rapid and feasible, which makes analysis of the paranasal sinus microbiome more accessible.Objective To detect respiratory viruses in the paranasal sinuses of patients with CRS and of healthy controls as well as to correlate clinical and radiographic measures of CRS with viral presence.Methods In this prospective study, 13 patients with CRS with nasal polyposis (CRSwNP) and 8 patients without nasal polyposis (CRSsNP) were enrolled and compared with 14 healthy controls. Samples were obtained from the paranasal sinuses and were screened for viral DNA with polymerase chain reaction—based sequencing techniques. Typical symptoms of CRS, the Sinonasal Questionnaire, and objective measures, including the modified Lund-Mackay and modified Lund-Kennedy scores were obtained.Results Eighty percent of the positive screens (4/5) were found in patients with CRSsNP, whereas 20% of the positive tests (1/5) were in the CRSwNP group, and none of the controls tested positive (p = 0.0029). Coronavirus was the most common virus detected. Sinonasal Questionnaire scores of the patients with CRS who tested positive for viruses were higher but not statistically different than those without a positive screen (p = 0.31). Radiographic and endoscopic measures of disease were not significantly different in the setting of a positive viral screen (p = 0.12 and 0.11 respectively).Conclusion Although traditionally difficult, advances in molecular sequencing enhance detection of viruses in the sinonasal tract. In this study, respiratory viruses were more commonly isolated from patients with CRS compared with healthy controls. Moreover, viral infection may play a greater role in symptom exacerbation in CRSsNP than in CRSwNP. These findings warrant further investigation into the role of the viral microbiome in CRS.

IMPORTANCE: Anosmia, the loss of the sense of smell, has profound implications for patient safety, well-being, and quality of life, and it is a predictor of patient frailty and mortality. Exposure to air pollution may be an olfactory insult that contributes to the development of anosmia. OBJECTIVE: To investigate the association between long-term exposure to particulate matter (PM) with an aerodynamic diameter of no more than 2.5 µm (PM2.5) with anosmia. DESIGN, SETTING, AND PARTICIPANTS: This case-control study examined individuals who presented from January 1, 2013, through December 31, 2016, at an academic medical center in Baltimore, Maryland. Case participants were diagnosed with anosmia by board-certified otolaryngologists. Control participants were selected using the nearest neighbor matching strategy for age, sex, race/ethnicity, and date of diagnosis. Data analysis was conducted from September 2020 to March 2021. EXPOSURES: Ambient PM2.5 levels. MAIN OUTCOMES AND MEASURES: Novel method to quantify ambient PM2.5 exposure levels in patients diagnosed with anosmia compared with matched control participants. RESULTS: A total of 2690 patients were identified with a mean (SD) age of 55.3 (16.6) years. The case group included 538 patients with anosmia (20%), and the control group included 2152 matched control participants (80%). Most of the individuals in the case and control groups were women, White patients, had overweight (BMI 25 to &lt;30), and did not smoke (women: 339 [63.0%] and 1355 [63.0%]; White patients: 318 [59.1%] and 1343 [62.4%]; had overweight: 179 [33.3%] and 653 [30.3%]; and did not smoke: 328 [61.0%] and 1248 [58.0%]). Mean (SD) exposure to PM2.5 was significantly higher in patients with anosmia compared with healthy control participants at 12-, 24-, 36-, 60-month time points: 10.2 (1.6) µg/m3 vs 9.9 (1.9) µg/m3; 10.5 (1.7) µg/m3 vs 10.2 (1.9) µg/m3; 10.8 (1.8) µg/m3 vs 10.4 (2.0) µg/m3; and 11.0 (1.8) µg/m3 vs 10.7 (2.1) µg/m3, respectively. There was an association between elevated PM2.5 exposure level and odds of anosmia in multivariate analyses that adjusted for age, sex, race/ethnicity, body mass index, alcohol or tobacco use, and medical comorbidities (12 mo: odds ratio [OR], 1.73; 95% CI, 1.28-2.33; 24 mo: OR, 1.72; 95% CI, 1.30-2.29; 36 mo: OR, 1.69; 95% CI, 1.30-2.19; and 60 mo: OR, 1.59; 95% CI, 1.22-2.08). The association between long-term exposure to PM2.5 and the odds of developing anosmia was nonlinear, as indicated by spline analysis. For example, for 12 months of exposure to PM2.5, the odds of developing anosmia at 6.0 µg/m3 was OR 0.79 (95% CI, 0.64-0.97); at 10.0 µg/m3, OR 1.42 (95% CI, 1.10-1.82); at 15.0 µg/m3, OR 2.03 (95% CI, 1.15-3.58). CONCLUSIONS AND RELEVANCE: In this study, long-term airborne exposure to PM2.5 was associated with anosmia. Ambient PM2.5 represents a potentially ubiquitous and modifiable risk factor for the loss of sense of smell.

Introduction Silent sinus syndrome (SSS) is a condition characterized by ophthalmologic features, such as spontaneous enophthalmos and hypoglobus with ipsilateral maxillary sinus atelectasis and an otherwise asymptomatic presentation. SSS has been documented secondary to a number of external causes, including trauma or surgery, but has less commonly been described in the setting of a potential mass in the deep masticator space.Case Presentation A 56-year-old woman with a history of chronic headaches with normal prior sinonasal imaging presented with increasing right-sided facial pain and headaches that radiated to her occiput, subjective visual changes, sharp ear pain, and long-standing subjective diminished sense of smell. Physical examination was normal, while nasal endoscopy demonstrated lateral bowing of the medial maxillary wall on the right. Magnetic resonance imaging demonstrated a homogenous 2 × 2 × 2.4 cm T1- and T2-weighted, hyperintense mass lesion in the deep masticator space splaying the right medial and lateral pterygoid muscles concerning for a possible lipomatous lesion. Computed tomography revealed an atelectatic and opacified maxillary sinus with inward bowing of the posterior maxillary wall and increased orbital volume on that side. Endoscopic maxillary antrostomy was performed with biopsy of the retromaxillary space lesion and with near immediate resolution of the patient’s symptoms. Histologic examination of the mass demonstrated mature adipose tissue with few aggregates of benign small vessels.Discussion This is an unusual presentation of SSS, with an accompanying enlargement of the retromaxillary fat pad. We herein review our clinical experience with SSS and provide a literature review of the presentation, management, and perioperative considerations for SSS.
