BACKGROUND: In the 5 years that have passed since the publication of the 2018 International Consensus Statement on Allergy and Rhinology: Allergic Rhinitis (ICAR-Allergic Rhinitis 2018), the literature has expanded substantially. The ICAR-Allergic Rhinitis 2023 update presents 144 individual topics on allergic rhinitis (AR), expanded by over 40 topics from the 2018 document. Originally presented topics from 2018 have also been reviewed and updated. The executive summary highlights key evidence-based findings and recommendation from the full document.METHODS: ICAR-Allergic Rhinitis 2023 employed established evidence-based review with recommendation (EBRR) methodology to individually evaluate each topic. Stepwise iterative peer review and consensus was performed for each topic. The final document was then collated and includes the results of this work.RESULTS: ICAR-Allergic Rhinitis 2023 includes 10 major content areas and 144 individual topics related to AR. For a substantial proportion of topics included, an aggregate grade of evidence is presented, which is determined by collating the levels of evidence for each available study identified in the literature. For topics in which a diagnostic or therapeutic intervention is considered, a recommendation summary is presented, which considers the aggregate grade of evidence, benefit, harm, and cost.CONCLUSION: The ICAR-Allergic Rhinitis 2023 update provides a comprehensive evaluation of AR and the currently available evidence. It is this evidence that contributes to our current knowledge base and recommendations for patient evaluation and treatment.

Previous work has shown the chemosensory dysfunction item of the 22-item Sinonasal Outcome Test (SNOT-22) that assesses problems with "taste/smell" has poor psychometric performance compared with other items on the SNOT-22, which we have hypothesized is due to the simultaneous assessment of two different senses. Our aim was to determine whether distinct smell and taste items in the SNOT-22 would improve psychometric performance.One hundred and eighty-one CRS patients were recruited and completed the SNOT-22. Additional items querying problems with the senses of "smell" and "taste," using the same response scale and recall period were given to study participants. Item response theory (IRT) was used to determine IRT parameters, including item discrimination, difficulty, and information provided by each SNOT-22 item.Confirming previous studies, the chemosensory item of the SNOT-22 (reflecting "taste/smell") had poor psychometric performance. Use of a distinct smell or taste item instead of the combined "taste/smell" item did not improve psychometric performance. However, a dedicated smell question resulted in a left shift of threshold parameters, showing that the dedicated smell item better captures moderate CRS disease burden than the original taste/smell item of the SNOT-22, which by virtue of near-identical IRT parameters appears to more greatly reflect problems with taste.A dedicated smell- or taste-specific item, rather than the combined "taste/smell" item currently in the SNOT-22 does not provide significantly greater psychometric performance. However, a dedicated smell item may better capture moderate CRS disease burden compared with the current chemosensory item on the SNOT-22. Laryngoscope, 132:1644-1651, 2022.

The objectives of this study were to determine the degree of citation skew in otolaryngology journals and how article citation distribution affects their impact factors (IFs). Forty-one "otorhinolaryngology" journals in the Clarivate Journal Citation Reports database were identified and their article citation data from 2017 to 2020 extracted. Article citation frequency was remarkably similar across most journals, consistent with the narrow distribution of IFs (mean [SD], 1.9 [0.9]). Although the percentage of a journal's articles cited more than its IF during the IF citation window (mean [SD] of 32.4% [7.9%] of journals' articles)-reflecting citation skew-was not correlated with IF, the percentage of a journal's articles that were cited at least once (mean [SD] of 62.5% [15.3%] of articles) was highly correlated (ρ = 0.92

The burden of chronic rhinosinusitis (CRS) symptomatology is frequently measured with the 22-item Sinonasal Outcome Test (SNOT-22). In some situations, such as when there is need for frequent sampling, a full SNOT-22 may be impractical, and an abbreviated measure may be useful. Herein, we study 4 questions reflecting the 4 SNOT-22 subdomains as accurate reflections of SNOT-22 content. In total, 250 patients with CRS completed a SNOT-22 and answered 4 questions about their total nasal symptoms, poor sleep quality, ear/facial pain, and mood (reflecting SNOT-22 subdomains) using visual analog scales (VASs). The 4 SNOT-22 subdomain VAS scores each correlated strongly with the corresponding SNOT-22 subdomain scores. The sum of the 4 subdomain question VAS scores was highly correlated with the total SNOT-22 score (

Objectives This study seeks to comprehensively analyze the impact of smoking history on outcomes after endoscopic transsphenoidal hypophysectomy (TSH) for pituitary adenoma. Design This was a retrospective study. Setting This study was done at the tertiary care center. Participants Three hundred and ninety-eight adult patients undergoing TSH for a pituitary adenoma. Main Outcome Measures Clinical and tumor characteristics and operative factors were collected. Patients were categorized as never, former, or active smokers, and the pack-years of smoking history was collected. Years since cessation of smoking was obtained for former smokers. Specific outcomes included postoperative cerebrospinal fluid (CSF) leak, length of hospitalization, 30-day return to the operating room, and 30-day readmission. Smoking history details were comprehensively analyzed for association with outcomes. Results Any history of smoking tobacco was associated with return to the operating room (odds ratio [OR] = 2.67, 95% confidence interval [CI]: 1.05–6.76, p = 0.039), which was for persistent CSF leak in 58.3%. Among patients with postoperative CSF leak, any history of smoking was associated with need for return to the operating room to repair the CSF leak (OR = 5.25, 95% CI: 1.07–25.79, p = 0.041). Pack-years of smoking was positively associated with a return to the operating room (OR = 1.03, 95% CI: 1.01–1.06, p = 0.048). In all multivariable models, all negative outcomes were significantly associated with the covariate: occurrence of intraoperative CSF leak. Conclusion This is the first study to show smoking may have a negative impact on healing of CSF leak repairs after TSH, requiring a return to the operating room. This effect appears to be dose dependent on the smoking history. Secondarily, intraoperative CSF leak as covariate in multivariable models was significantly associated with all negative outcomes.

Objective Endonasal dural suturing (EDS) has been reported to decrease the incidence of cerebrospinal fluid fistula. This technique requires handling of single-shaft instrumentation in the narrow endonasal corridor. It has been proposed that three-dimensional (3D) endoscopes were associated with improved depth perception. In this study, we sought to perform a comparison of two-dimensional (2D) versus 3D endoscopy by assessing surgical proficiency in a simulated model of EDS. Materials and Methods Twenty-six participants subdivided into groups based on previous endoscopic experience were asked to pass barbed sutures through preset targets with either 2D (Storz Hopkins II) or 3D (Storz TIPCAM) endoscopes on 3D-printed simulation model. Surgical precision and procedural time were measured. All participants completed a Likert scale questionnaire. Results Novice, intermediate, and expert groups took 11.0, 8.7, and 5.7 minutes with 2D endoscopy and 10.9, 9.0, and 7.6 minutes with 3D endoscopy, respectively. The average deviation for novice, intermediate, and expert groups (mm) was 5.5, 4.4, and 4.3 with 2D and 6.6, 4.6, and 3.0 with 3D, respectively. No significant difference in procedural time or accuracy was found in 2D versus 3D endoscopy. 2D endoscopic visualization was preferred by the majority of expert/intermediate participants, while 3D endoscopic visualization by the novice group. Conclusion In this pilot study, there was no statistical difference in procedural time or accuracy when utilizing 2D versus 3D endoscopes. While it is possible that widespread familiarity with 2D endoscopic equipment has biased this study, preliminary analysis suggests that 3D endoscopy offers no definitive advantage over 2D endoscopy in this simulated model of EDS.

To determine factors associated with social media usage for finding a doctor or seeking medical advice among otolaryngology patients.Cross-sectional study of 361 patients visiting our clinics. All participants were asked if they were aware social media may be used to find doctors and if they had ever done so, and also if they were aware social media could be used to get advice about a medical condition or its treatment and if they had ever done so. Demographic characteristics were examined for association with affirmative answers to these questions.Facebook was the most used social media platform with 50.7% using Facebook daily. Over 50% of participants were aware social media could be used to find a doctor or seek medical advice. Daily use of Facebook was associated with using social media for finding a doctor (OR = 2.57, 95%CI: 1.41-4.67, p = 0.002) and seeking medical advice (OR = 1.72, 95%CI: 1.09-2.71, p = 0.020). Having Medicare was associated with using social media to find a doctor (OR = 2.20, 95%CI: 1.15-4.21, p = 0.017), whereas Medicaid was associated with using social media for medical advice (OR = 1.99, 95%CI: 1.08-3.67, p = 0.027).A majority of otolaryngology patients may be aware of health care applications of social media, with Facebook being the dominant platform, and Medicare insurance identifying patients who may most use social media in this manner. There is also an indication that social determinants of health, as reflected by Medicaid insurance, may be associated with using social media to seek medical advice.NA Laryngoscope, 2022.

The SNOT-22 (22-item Sinonasal Outcome Test) is a high-quality outcome measure that assesses chronic rhinosinusitis-specific quality of life. The aim of this study was to gain greater insight into the information provided by the SNOT-22 by determining its item-based psychometric properties.Retrospective cohort study.Tertiary care academic centers.This study used a previously described data set of the SNOT-22 completed by 800 patients with chronic rhinosinusitis. Item response theory graded response models were used to determine parameters reflecting item discrimination, difficulty, and information provided by each item toward the SNOT-22 subdomain to which it belonged.The unconstrained graded response model fitted the SNOT-22 data best. Item discrimination parameters and total information provided showed the greatest variability within the nasal subdomain, and the item related to sense of smell/taste demonstrated the lowest discrimination and provided the least amount of information overall. The dizziness item provided disparately lower total information and discrimination in the otologic/facial pain subdomain. Items in the sleep and emotional subdomains generally provided high discrimination. While items in the nasal, sleep, and otologic/facial pain subdomains spanned all levels of difficulty, emotional subdomain items covered higher levels of difficulty, indicating greater information provided at higher levels of disease severity.The item-specific psychometric properties of the SNOT-22 support it as a high-quality instrument. Our results suggest the need and possibility for revision of the smell/taste dysfunction item, for example its wording, to improve its ability to discriminate among the different levels of disease burden.

Acute exacerbations of chronic rhinosinusitis (AECRS) are currently defined as a transient worsening of symptoms that return to baseline. This definition is narrow and can only be made retrospectively. The literature has studied this phenomenon from the physician perspective, yet a key stakeholder's-the patient's perspective is not well elucidated in the literature. To understand AECRS from the patient's perspective, we performed this study to further clarify this phenomenon.Basic qualitative study via patient interviews using constant comparative methodology was conducted.Tertiary care academic center.Two of the authors served as coders, and via group discussion, a common codebook was created and used to identify recurrent themes. The themes were analyzed for meaning and conclusions were summarized.Ten interviews were conducted with chronic rhinosinusitis (CRS) patients. Recurring themes included the following: (1) patients identify with the termBeyond worsening of sinonasal symptoms, the concept of AECRS reflects a more complex construct to patients with associated extranasal symptoms and systemic manifestations. In addition, AECRS have a large impact on patients, and therefore, understanding this component of CRS is pivotal in improving disease control and QOL in this patient population.

Objective Patient reported outcome measures (PROMs) for assessment of chronic rhinosinusitis (CRS) employ a variety of recall periods and response scales for reporting CRS symptom burden. CRS patient perspective is unknown with respect to recall periods and response scales in PROMs. Design Cross-sectional study. Setting Tertiary rhinology clinic. Participants 63 adults with CRS. Main outcome measures Participants were asked to choose which CRS symptom recall period - one day, two weeks, one month, or greater than one month - was most reflective of their current disease state and best to base treatment recommendations (including surgery) upon. Participants were also asked to report on which of six response scales (one visual analogue scale [VAS] and five Likert scales ranging from four to eight items) was easiest to use and understand, and most preferred. Results A majority of participants felt the current state of their CRS symptoms was best reflected by a recall period of two weeks to one month; however, patients preferred that recommendations about treatments, including endoscopic sinus surgery, be determined by symptoms experienced over at least a one-month period. Participants generally found the VAS and seven-item Likert scale to be the easiest to use and understand, and their most preferred scales. No patient characteristics associated with preferences for recall periods or response scales. Conclusion Future PROMs for CRS symptoms should consider assessment of symptoms over a one-month time frame and use either a VAS or seven-item Likert response scale to optimally balance reflection of current disease state, need for intervention and patient preference.

Opioid use disorder (OUD), which includes the morbidity of dependence and mortality of overdose, has reached epidemic proportions in the United States. Overprescription of opioids can lead to chronic use and misuse, and unused narcotics after surgery can lead to their diversion. Research supports that most patients do not take all the prescribed opioids after surgery and that surgeons are the second largest prescribers of opioids in the United States. The introduction of opioids in those with OUD often begins with prescription opioids. Reducing the number of extra opioids available after surgery through smaller prescriptions, safe storage, and disposal should reduce the risk of opioid use disorder in otolaryngology patients and their families.The purpose of this specialty-specific guideline is to identify quality improvement opportunities in postoperative pain management of common otolaryngologic surgical procedures. These opportunities are communicated through clear actionable statements with explanation of the support in the literature, evaluation of the quality of the evidence, and recommendations on implementation. Employing these action statements should reduce the variation in care across the specialty and improve postoperative pain control while reducing risk of OUD. The target patients for the guideline are any patients treated for anticipated or reported pain within the first 30 days after undergoing common otolaryngologic procedures. The target audience of the guideline is otolaryngologists who perform surgery and clinicians who manage pain after surgical procedures. Outcomes to be considered include whether the patient has stopped using opioids, has disposed of unused opioids, and was satisfied with the pain management plan.The guideline addresses assessment of the patient for OUD risk factors, counseling on pain expectations, and identifying factors that can affect pain duration and/or severity. It also discusses the use of multimodal analgesia as first-line treatment and the responsible use of opioids. Last, safe disposal of unused opioids is discussed.This guideline is intended to focus on evidence-based quality improvement opportunities judged most important by the guideline development group. It is not a comprehensive guide on pain management in otolaryngologic procedures. The statements in this guideline are not intended to limit or restrict care provided by clinicians based on their experiences and assessments of individual patients.The guideline development group made

Purpose Temporal trends of disease-specific internet searches may provide novel insights into seasonal dynamics of disease burden and, by extension, disease pathophysiology. The aim of this study was to define the temporal trends in rhinosinusitis-specific internet searches. Methods This was a cross sectional analysis of search volume for predefined search terms. Google trends was used to explore the volume of searches for five specific search terms related to rhinosinusitis: nose, mucus, sinus, sinusitis, chronic sinusitis, which were entered into Google web search between 2004 and 2019. Results were analyzed within search “context” which included temporally associated related searches. Relative search volume (RSV) was analyzed for English and non-English speaking countries from the Northern and Southern hemispheres. Analysis of seasonality was performed using the cosinor model. Results The five specific search terms were most related to rhinosinusitis-related search contexts, indicating that they were appropriately reflective of internet queries by patients for rhinosinusitis. The RSV for rhinosinusitis-related terms and more general search terms increased with each passing year indicating constant interest in rhinosinusitis. Cosinor time series analysis revealed inquiry peaks in winter months for all five specific rhinosinusitis-related search terms independent from the hemisphere. Conclusion Over a 15-year period, Google searches with rhinosinusitis-specific search terms consistently peaked during the winter around the world. These findings indirectly support the model of viral infection or exposure as the predominant cause of acute rhinosinusitis and acute exacerbations of chronic rhinosinusitis.

I. Executive summary BACKGROUND: The 5 years since the publication of the first International Consensus Statement on Allergy and Rhinology: Rhinosinusitis (ICAR-RS) has witnessed foundational progress in our understanding and treatment of rhinologic disease. These advances are reflected within the more than 40 new topics covered within the ICAR-RS-2021 as well as updates to the original 140 topics. This executive summary consolidates the evidence-based findings of the document. Methods ICAR-RS presents over 180 topics in the forms of evidence-based reviews with recommendations (EBRRs), evidence-based reviews, and literature reviews. The highest grade structured recommendations of the EBRR sections are summarized in this executive summary. Results ICAR-RS-2021 covers 22 topics regarding the medical management of RS, which are grade A/B and are presented in the executive summary. Additionally, 4 topics regarding the surgical management of RS are grade A/B and are presented in the executive summary. Finally, a comprehensive evidence-based management algorithm is provided. Conclusion This ICAR-RS-2021 executive summary provides a compilation of the evidence-based recommendations for medical and surgical treatment of the most common forms of RS.

We look back at the end of what soon will be seen as an historic year, from COVID-19 to real-world introduction of biologicals influencing the life of our patients. This review describes the important findings in Rhinology over the past year. A large body of evidence now demonstrates loss of sense of smell to be one of the most common symptoms of COVID-19 infection; a meta-analysis of 3563 patients found the mean prevalence of self-reported loss to be 47%. A number of studies have now shown long-term reduced loss of smell and parosmia. Given the high numbers of people affected by COVID-19, even with the best reported recovery rates, a significant number worldwide will be left with severe olfactory dysfunction. The most prevalent causes for olfactory dysfunction, besides COVID-19 and upper respiratory tract infections in general, are trauma and CRSwNP. For these CRSwNP patients a bright future seems to be starting with the development of treatment with biologics. This year the Nobel prize in Medicine 2021 was awarded jointly to David Julius and Ardem Patapoutian for their discoveries of receptors for temperature and touch which has greatly enhanced our understanding of nasal hyperreactivity and understanding of intranasal trigeminal function. Finally, a new definition of chronic rhinitis has been proposed in the last year and we have seen many papers emphasizing the importance of endotyping patients in chronic rhinitis and rhinosinusitis in order to optimise treatment effect.

There is a paucity of data in the literature describing quantitative exposure of the ventral craniocervical junction through the endonasal corridor in a safe manner mindful of locoregional anatomy.To quantify ventromedial exposure of O-C1 and C1-2 articular structures after turning an inverted U-shaped nasopharyngeal flap (IUNF) and to obtain measurements assessing the distance of flap margins to adjacent neurovascular structures.In 8 cadaveric specimens, an IUNF was fashioned using a superior incision below the level of the pharyngeal tubercule of the clivus and lateral incisions in the approximate region of Rosenmuller fossae bilaterally. Measurements with calipers and/or neuronavigation software included flap dimensions, exposure of O-C1 and C1-2 articular structures, inferior reach of IUNF, and proximity of the internal carotid artery (ICA) and hypoglossal nerve to IUNF margins.The IUNF facilitated exposure of an average of 9 mm of the medial surfaces of the right/left O-C1 joints without transgression of the carotid arteries or hypoglossal nerves. The C1-2 articulation could not be routinely accessed. The margins of the IUNF were not in close (5 mm) proximity to the ICA in any of the 8 specimens. In 6 of 8 specimens, the dimensions of the IUNF were in close (5 mm) horizontal or vertical proximity to the hypoglossal foramina.The IUNF provided safe and reliable access to the medial O-C1 articulation. Given the close proximity of the exocranial hypoglossal foramen, neuronavigation assistance and neuromonitoring with attention to the superolateral IUNF margin are recommended.

Odontoidectomy for ventral compressive pathology may result in O-C1 and/or C1-2 instability. Same-stage endonasal C1-2 spinal fusion has been advocated to eliminate risks associated with separate-stage posterior approaches. While endonasal methods for C1 instrumentation and C1-2 trans-articular stabilization exist, no hypothetical construct for endonasal occipital instrumentation has been validated. We provide an anatomic description of anterior occipital condyle (AOC) screw endonasal placement as proof-of-concept for endonasal craniocervical stabilization.Eight adult, injected cadaveric heads were studied for placing 16 AOC screws endonasally. Thin-cut CT was used for registration. After turning a standard inferior U-shaped nasopharyngeal flap endonasally, 4 mm × 22 mm AOC screws were placed with a 0° driver using neuronavigation. Post-placement CT scans were obtained to determine: site-of-entry, measured from the endonasal projection of the medial O-C1 joint; screw angulation in sagittal and axial planes, proximity to critical structures.Average site-of-entry was 6.88 mm lateral and 9.74 mm rostral to the medial O-C1 joint. Average angulation in the sagittal plane was 0.16° inferior to the palatal line. Average angulation in the axial plane was 23.97° lateral to midline. Average minimum screw distances from the jugular bulb and hypoglossal canal were 4.80 mm and 1.55 mm.Endonasal placement of AOC screws is feasible using a 0° driver. Our measurements provide useful parameters to guide optimal placement. Given proximity of hypoglossal canal and jugular bulb, neuronavigation is recommended. Biomechanical studies will ultimately be necessary to evaluate the strength of AOC screws with plate-screw constructs utilizing endonasal C1 lateral mass or C1-2 trans-articular screws as inferior fixation points.

Eustachian tube dysfunction (ETD) is a common otolaryngologic condition associated with decreased quality of life. The first-line treatment of ETD is intranasal corticosteroid sprays (INCS). Computational fluid dynamics (CFD) was used to study particle deposition on the Eustachian tube (ET) using two commercial INCS (Flonase and Sensimist). Simulations also considered the effects of nostril side, insertion depth, insertion angle, cone spray angle, inhaling rates, wall impingement treatment, and fluid film. Flonase and Sensimist produced different particle size distributions and sizes. Sensimist droplets are smaller, less sensitive to asymmetry in nostrils anatomy and variation in insertion angle, and therefore can reach the posterior nasopharynx more readily. Flonase produces larger particles with greater inertia. Its particles deposition is more sensitive to intrasubject variation in nasal anatomy and insertion angles. The particle deposition on the ET was sensitive to the wall impingement model. The deposition on the ET was insignificant with adherence only

OBJECTIVE Anchor-based methods to calculate the minimal clinically important difference (MCID) of a patient-reported outcome measure (PROM) may suffer from recall bias. This has never been investigated for otolaryngic PROMs. We sought to identify evidence of recall bias in calculation of MCIDs of PROMs for patients with chronic rhinosinusitis (CRS). DESIGN Retrospective analysis of data from two previous studies calculating the MCID of the 22-item Sinonasal Outcome Test (SNOT-22) and 5-dimensonal EuroQol questionnaire (EQ-5D) in CRS patients. SETTING Tertiary rhinology clinic. PARTICIPANTS Adults with CRS. MAIN OUTCOME MEASURES SNOT-22 score, and EQ-5D visual analog scale scores (EQ-5D VAS) and health utility values (EQ-5D HUV) before and after medical treatment for CRS. After treatment, participants were asked to rate the change in sinonasal symptoms and general health (the anchor question) as "Much worse," "A little worse," "About the same," "A little better" or "Much better." Participants' responses to the anchor question were checked for association with post-treatment and pre-treatment scores using ordinal regression. RESULTS On univariate association, post-treatment SNOT-22 and EQ-5D scores were associated with respective participants' anchor question responses (P

Objective Repair of cerebrospinal fluid (CSF) leaks of the lateral recess of the sphenoid (LRS) sinus can be challenging to accomplish via an endoscopic transphenoidal approach. The endoscopic transpterygoid approach can improve surgical access to the lateral recess but requires more extensive surgical dissection. We review our experience with LRS CSF leak repair via both techniques to determine whether preoperative radiologic data can help predict the most appropriate surgical approach. Methods Electronic medical records of patients with LRS CSF leaks were retrospectively reviewed at a single tertiary referral center. Radiographic measurements from preoperative computed tomography images were reviewed. Results Twenty‐two LRS CSF leaks were identified. The transphenoidal and transpterygoid approach were used in 6 (27.3%) and 16 (72.7%) cases, respectively. The mean vidian canal to foramen rotundum angle of the repairs accessed transphenoidally as compared to the transptyergoid approach were not significantly different (41.93° ±10.91, 40.72° ±19.49, respectively; P = .63). However, the mean volume of the LRS accessed by the transpterygoid approach was significantly greater compared to those accessed through the transphenoidal approach (0.97 cm3 ± 0.48, 0.39 cm3 ± 0.40, respectively; P = .04). A LRS volume of 0.400 cm3 or greater predicted the use of the transpterygoid approach with 93.3% sensitivity and 60.0% specificity. Conclusion This study demonstrated that LRS CSF leaks that necessitated repair by the transpterygoid approach, rather than transphenoidal approach, were in the context of significantly larger lateral recess. Assessment of the LRS volume is a quantifiable parameter to aid in preoperative surgical planning. Level of Evidence Level 4., The endoscopic endonasal surgical approach is the gold standard in these repairs, however, the LRS sinus is particularly challenging due to anatomical constraints. Another method, known as the endoscopic endonasal transpterygoid (ETTP) approach has been used, but requires a more invasive process. Depending on the location of the CSF leak, maneuverability limitations and risks are important to consider. Our goal is to define a quantifiable parameter that will be useful in preoperative surgical planning to determine the safest, most effective approach on a case‐by‐case basis.

ObjectiveWe sought to determine if chronic rhinosinusitis (CRS) patients with nasal polyps (CRSwNP) differentially perceived CRS symptom burden compared to patients without nasal polyps (CRSsNP) and to what extent CRS symptom severity was associated with quality of life (QOL) and patient-reported symptom control in the 2 groups.MethodsA total of 600 patients (266 CRSwNP and 334 CRSsNP) presenting with CRS were recruited. CRS symptom burden was assessed with the 22-item Sinonasal Outcome Test (SNOT-22). SNOT-22 nasal, sleep, ear/facial discomfort, and emotional subdomain scores were calculated. General health-related QOL was assessed with the visual analog scale of the 5-dimensional EuroQol questionnaire (EQ-5D VAS). Patients rated their CRS symptom control on a 5-point scale.ResultsSNOT-22 scores did not differ between CRSwNP (mean: 35.6) and CRSsNP (mean: 36.3). There were no differences in nasal, sleep, and emotional subdomains of the SNOT-22. CRSsNP had higher ( P = .003) ear/facial subdomain scores than CRSwNP, while CRSwNP reported greater hyposmia ( P ConclusionCRSwNP and CRSsNP have differences in symptom profile, effect on health-related QOL, and patient-perceived symptom control. CRSsNP experience significantly greater burden of ear/facial discomfort, while CRSwNP report greater hyposmia. Although CRSsNP reports lower general health-related QOL overall, CRSwNP patients had lower levels of CRS symptom control for every incremental increase in symptom burden suggesting greater sensitivity/intolerance to CRS symptoms.

Coronavirus disease 2019 (COVID-19) is a global pandemic affecting millions of individuals, killing hundreds of thousands. Although typically described with characteristic symptoms of fever, cough, and shortness of breath, greater understanding of COVID-19 has revealed myriad clinical manifestations. Olfactory dysfunction (OD)-hyposmia and anosmia-has recently been recognized as an important symptom of COVID-19 and increasingly gained traction as a public health tool for identifying COVID-19 patients, in particular otherwise asymptomatic carriers who, unawares, may be major drivers of disease spread. The objective of this study is to review the scientific evidence about anosmia in COVID-19.PubMed, Google Scholar, and Web of Science.Comprehensive literature search of primary studies pertinent to the objectives of this review using the chosen data sources.Current evidence shows that OD is highly prevalent in COVID-19, with up to 80% of patients reporting subjective OD and objective olfactory testing potentially showing even higher prevalence. OD is frequently accompanied by taste dysfunction. Up to 25% of COVID-19 patients may experience sudden-onset OD as the first symptom. A large proportion of COVID-19 OD cases may resolve over the period of a few weeks.Sudden anosmia should be considered a symptom of COVID-19. Assessing for sudden-onset anosmia may increase sensitivity of COVID-19 screening strategies, in particular for identifying patients at the earliest stages of disease. Since many cases of OD due to COVID-19 may resolve in the short term, conservative management, including observation, is reasonable, while advanced imaging is unnecessary.

Objective Intranasal saline irrigations and intranasal corticosteroids are supported by level-1 evidence for medical management of chronic rhinosinusitis (CRS). We sought to study adherence with these medications. Methods Prospective study of 174 patients with CRS. Patients reported their usage of intranasal saline irrigation and intranasal corticosteroid over the preceding 3 months, at presentation, and a subsequent follow-up visit 3 to 12 months later. Adherence was defined as reported medication usage for ≥6 days per week. Results At the time of presentation, 44.3% of patients were using an intranasal corticosteroid spray or irrigation ≥6 days/week, whereas only 24.1% were using saline irrigation ≥6 days per week. At follow-up, 60.3% of patients were using either an intranasal corticosteroid spray or irrigation ≥6 days per week, whereas 35.6% were using saline irrigation ≥6 days per week. Adherence with intranasal corticosteroids was associated with comorbid asthma (adjusted odds ratio [OR] = 2.68, 95% confidence interval [CI]: 1.10-6.50, P = 0.029), allergy (OR = 2.22, 95% CI: 1.05-4.71, P = 0.037), and change in 22-item Sinonasal Outcome Test score (OR = 0.98, 95% CI: 0.96-0.99, P = 0.027). Use of intranasal corticosteroid sprays versus irrigations (OR = 2.56, 95% CI: 0.84-7.83, P = 0.099) was suggestive of association with improved adherence. Adherence with intranasal saline irrigation was associated with age (OR = 1.02, 95% CI: 1.01-1.05, P = 0.034). Conclusion Usage and adherence with intranasal steroids and saline may be low in CRS patients even with management in a tertiary level, subspecialty rhinology clinic. Adherence with medications represents a major opportunity for improving patient care and outcomes, specifically by targeting patients with lower disease burden and improving convenience of medications.

Background The association between sinonasal microbiome and clinical outcomes of patients with chronic rhinosinusitis (CRS) is unclear. We performed a systematic review of prior studies evaluating the CRS microbiome in relation to clinical outcomes. Methods Computerized searches of PubMed/Medline, Cochrane, and EMBASE were updated through October 2019 revealing a total of 9 studies including 244 CRS patients. A systematic review of the literature was performed, including data extraction focusing on sample region, sequencing platforms, predominant organisms, and outcomes measures. Results Nine criterion-meeting studies included 244 CRS patients, with varied results. Eight studies used 16s-ribosomal RNA (16s-rRNA) gene sequencing to assess the sinonasal microbiome and 1 used 16s-rRNA PhyloChip analysis. Seven studies used Sino-Nasal Outcome Test scores, 1 applied another CRS symptom metric, and 1 used need for additional procedures/antibiotics as the primary clinical outcome. Three studies suggest that baseline abundance of phylum Actinobacteria (specifically genus Corynebacterium) was predictive of better surgical outcome. One study found C. tuberculostearicum was positively correlated with symptom severity. Another study revealed genus Escherichia was overrepresented in CRS and had positive correlation with increased symptom scores. In addition, 1 study identified Acinetobacter johnsonii to be associated with improvement in symptom scores while supporting Pseudomonas aeruginosa as having a negative impact on quality of life. Conclusion Microbiome data are varied in their association with clinical outcomes of CRS patients. Further research is required to identify if predominance of certain microbes within the microbiome is predictive of CRS patients' outcomes.

Knowledge of chronic rhinosinusitis (CRS) epidemiology may directly impact patient care: aiding patient identification and establishing accurate diagnosis as well as informing treatment decisions. The objective of this review is to summarize the current evidence on the epidemiology of CRS, with a focus on prevalence and risk factors. Although the presence of either symptoms or objective findings alone have yielded CRS prevalence estimates of over 10%, the presence of both-consistent with guideline-based diagnostic criteria for CRS-has suggested that the true prevalence of CRS is consistently less than 5%, with approximately one-third of patients with CRS having nasal polyps, in epidemiologic studies from around the world. In comparison, the prevalence of CRS endotypes-pathophysiologic subclassification of CRS most commonly as related to type 2 or non-type 2 inflammation-has been found to vary significantly by region. The epidemiology of CRS is modified and ultimately determined by risk factors: genetic/hereditary, demographic, environmental, and imparted by predictive pre-/comorbid disease. The understanding of these epidemiologic relationships may help the provider to optimally identify and understand each individual's CRS disease process, thereby improving both diagnosis and treatment.

Academic rank and metrics such as total publications (pubs) and H-index are indicators to measure academic achievement. This study aims to determine whether there are gender differences in academic productivity or faculty appointments among endocrine surgeons in the United States.A database was generated from the American Association of Endocrine Surgeons (AAES) website. Community or academic practice was designated by institution affiliation and faculty appointment. Academic metrics, including pubs, H-index, and weighted-RCR (relative citation ratio), were obtained from public databases.A total of 258 AAES members were affiliated with an academic institution. The majority were men (58%). Overall, men in endocrine surgery had higher academic metrics: pubs (56.0 [26-134], 23.0 [11-56], P 0.0001), H-index (19.0 [11-35], 9.0 [5-21], P 0.0001), weighted-RCR (63.5 [22-193], 24.1 [8-74], P 0.005) and rank (associate professor or professor, P 0.0001). Subgroup analysis accounting for time in practice found no difference in total publications, weighted RCR, or faculty appointments between genders in practice for 0-5 y. However, among surgeons in practice for 6-10 y, men had higher academic metrics (pubs: 31.0 [16-79], 18.5 [9-33]; RCR: 46.0 [14-102], 13.3 [9-34]) and faculty appointments (all P 0.05).There are gender disparities in academic productivity and faculty appointment among US endocrine surgeons. While junior faculty show no gender differences in most indicators of academic productivity or rank, men with 6-10 y in practice have higher average academic metrics and rank. Whether the absence of gender disparities among junior faculty is a sustainable reflection of recent efforts to encourage equal mentorship and professional opportunities or whether disparities will manifest as faculty progress remains to be determined.
