Abstract
Chronic rhinosinusitis with nasal polyposis is a common inflammatory condition, with subtypes like aspirin-exacerbated respiratory disease, allergic fungal rhinosinusitis, and central compartment atopic disease sharing a common type 2 inflammatory pathway. Respiratory biologic therapies have been developed that target type 2 inflammation. In this article, we discuss the use of respiratory biologic therapies for nasal polyposis in general, as well as within the various subtypes of nasal polyps. Further, we discuss future roles of novel biologic therapies targeting type 2 inflammation in nasal polyposis.

Abstract
Allergy and asthma prevalence vary across different subsets of chronic rhinosinusitis with nasal polyposis. In this article, the authors investigate the management of allergy and asthma within populations of patients with aspirin-exacerbated respiratory disease, allergic fungal rhinosinusitis, and central compartment atopic disease. Topical steroids, nasal rinses, and endoscopic sinus surgery are frequently employed in the management of nasal polyposis. Further, other causes of upper and lower airway inflammation like allergy and asthma should be considered in the overall treatment plan in order to optimize outcomes.

Numerical and experimental analysis of pollen inhalation exposure in nasal airways following various middle turbinectomy. THE SCIENCE OF THE TOTAL ENVIRONMENT 2024; 907:168156. [PMID: 37898207 DOI: 10.1016/j.scitotenv.2023.168156] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 06/26/2023] [Revised: 10/24/2023] [Accepted: 10/25/2023] [Indexed: 10/30/2023]
Abstract
BACKGROUND Middle turbinectomy (MT) has always been controversial. MT significantly alters the anatomy and redistributes the inhaled air. The current study is designed to quantify the effect of MT with varying resection volumes on airflow and associated pollen inhalation exposure characteristics in the nasal airways. METHODS Six realistic models following bilateral comprehensive Functional Endoscopic Sinus Surgery (FESS) deriving from CT images were constructed and their corresponding post-MT models with four types of MT procedures were virtually conducted. Inhalation exposure to pollen particles was simulated by the Computational Fluid-Particle Dynamics (CFPD) approach and validated through in vitro experiments. RESULTS Following the excision of the middle turbinate, a significant escalation in airflow was observed within the upper-middle region of the nasal cavities. Pollen deposition was observed to be more prominent in the nasal septum, laryngopharynx, and maxillary sinus, varying with the types of MT procedures. Notably, particles with diameters smaller than 50 μm exhibited two distinct "high peaks" and three "small peaks" within the nasal airways. CONCLUSION MT resulted in increased airflow volume within the upper-middle region of the nasal cavities. Following MT, notable shifts in pollen particle deposition hot spots were observed, transitioning from the nasal vestibule, nasal septum, and middle meatus to the nasal septum and laryngopharynx. These findings are anticipated to contribute valuable perspectives on pollen inhalation exposure risk assessments following diverse MT surgical interventions.

Abstract
INTRODUCTION Central compartment atopic disease (CCAD) is a newly recognized variant subtype of chronic rhinosinusitis (CRS). Although CCAD has been reported to be correlated with allergy, there is still a considerable gap in our knowledge regarding CCAD. AREAS COVERED We have conducted a thorough analysis of the literature on CCAD. This review provides current understanding and therapeutic strategies of CCAD. In this article, we will review the clinical presentations and parameters, allergy-related etiology, endotypes, and recommended management of CCAD. EXPERT OPINION CCAD is considered as an aeroallergen-driven type 2/eosinophilic inflammatory pattern. Although CCAD can be diagnosed by endoscopy and radiology, as well as allergen test, pathogenesis and management strategies leave much to be desired, and further studies are needed.

Abstract
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.

Inhalation and deposition of spherical and pollen particles after middle turbinate resection in a human nasal cavity. Respir Physiol Neurobiol 2021; 294:103769.

Abstract
Middle turbinate resection significantly alters the anatomy and redistributes the inhaled air. The superior half of the main nasal cavity is opened up, increasing accessibility to the region. This is expected to increase inhalation dosimetry to the region during exposure to airborne particles. This study investigated the influence of middle turbinate resection on the deposition of inhaled pollutants that cover spherical and non-spherical particles (e.g. pollen). A computational model of the nasal cavity from CT scans, and its corresponding post-operative model with virtual surgery performed was created. Two constant flow rates of 5 L/min, and 15 L/min were simulated under a laminar flow field. Inhaled particles including pollen (non-spherical), and a spherical particle with reference density of 1000 kg/m3 were introduced in the surrounding atmosphere. The effect of surgery was most prominent in the less patent cavity side, since the change in anatomy was proportionally greater relative to the original airway space. The left cavity produced an increase in particle deposition at a flow rate of 15 L/min. The main particle deposition mechanisms were inertial impaction, and to a lesser degree gravitational sedimentation. The results are expected to provide insight into inhalation efficiency of different aerosol types, and the likelihood of deposition in different nasal cavity surfaces.

Abstract
BACKGROUND Central compartment atopic disease (CCAD) is a variant of chronic rhinosinusitis (CRS) with nasal polyps (CRSwNP) characterized by polypoid changes of the superior nasal septum, middle (MT), and/or superior turbinates (ST). This study evaluates surgical outcomes in patients with CCAD compared with other CRSwNP subtypes. METHODS Retrospective analysis was performed at Emory University from May 2012 to November 2019. Patients undergoing primary endoscopic sinus surgery (ESS) for CCAD, aspirin-exacerbated respiratory disease (AERD), allergic fungal rhinosinusitis (AFRS), and CRSwNP not otherwise specified (CRSwNP NOS) were included consecutively, beginning with the earliest date of CCAD patient. Outcome measures included polyp recurrence, revision ESS, oral steroid use, and oral antibiotic use. Pearson chi-square and univariate analysis of variance (ANOVA) were performed for group comparisons. RESULTS Data was collected for 132 patients (CCAD = 38, AERD = 20, AFRS = 37, CRSwNP NOS = 37; 58 females, mean age 42.9 years [range, 13-85 years]). CCAD patients demonstrated polyp recurrence less frequently than expected, whereas AFRS patients had polyp recurrence more frequently than expected (p = 0.003; phi 0.32). CCAD patients underwent revision ESS less frequently than expected; AFRS and CRSwNP NOS underwent revision ESS more frequently than expected (p = 0.03; phi 0.26). CRSwNP NOS patients received more total antibiotic courses than those with CCAD (p = 0.01; eta-squared 0.09) and more courses of antibiotics per month than those with AFRS (p = 0.03; eta-squared 0.07). There was no significant difference in follow-up measures across groups (number of visits, total months, or visits per month). CONCLUSION Rates of polyp recurrence and revision ESS were significantly lower in CCAD patients compared with patients with other CRSwNP subtypes, suggesting durable benefit of ESS and postoperative medical therapy in CCAD patients.

Abstract
OBJECTIVE To evaluate disease presence in the central compartment (CC) in patients with eosinophilic chronic rhinosinusitis (CRS). METHODS Patients with eosinophilic CRS were divided into three endotypes: aspirin-exacerbated respiratory disease (AERD), allergic fungal rhinosinusitis (AFRS), and eosinophilic CRS with nasal polyps (eCRSwNP). CT scans were reviewed for CC involvement, defined as the area between the superior nasal septum (SNS) and middle turbinate (MT). CC involvement was measured based on the degree of opacification (0: no opacification, 1: up to 50% opacification, and 2: >50% opacification), and distance from SNS to MT (mm). Patients who had lateralized MTs from prior surgery as the cause of CC widening were excluded. Patients who underwent orbital decompression were included as a control group. RESULTS Fifty patients in each group (AERD, AFRS, and eCRSwNP) and 50 control patients were included. Average number of surgeries was 2.5 in AERD (p = 0.05), 2 in AFRS (p = 0.4), and 1.7 in eCRSwNP. Preoperative CC distance was significantly higher in AERD versus control, AFRS, and eCRSwNP: 4.2 versus 2.8 mm (p < 0.0001), 4.2 versus 1.9 mm (p < 0.0001), and 4.2 versus 2.7 mm (p < 0.0001), respectively. Postoperatively, CC distance and degree of opacification were significantly higher in AERD versus control, AFRS, and eCRSwNP. Within the AERD group, CC distance was significantly higher postoperatively than preoperatively (6.5 vs. 4.2 mm, p = 0.002). CONCLUSION CC involvement is more significant in AERD patients and if present, rhinologists should be suspicious of the diagnosis. This area could represent a source of inflammatory load in patients with AERD.

Abstract
BACKGROUND Olfactory dysfunction (OD) associated with chronic rhinosinusitis (CRS) remains quite challenging. Instruments to precisely assess olfactory cleft anatomy and their association with olfaction are needed. METHODS The olfactory cleft endoscopy scale (OCES) was used to assess the olfactory cleft in healthy control subjects and a cohort of patients with CRS. Psychophysical and psychosocial olfactory function were assessed and correlations with OCES scores were measured. RESULTS Control subjects and subjects with CRS with nasal polyps (CRSwNP) and CRS without nasal polyps (CRSsNP) were enrol- led. OCES correlated with both psychophysical and psychosocial olfaction, as measured by threshold, discrimination and identi- fication (TDI) scores and Questionnaire on Olfactory Disorders (QOD-NS) scores for all case and control subjects combined. OCES improved in both CRS groups postoperatively with the highest correlation seen in postoperative olfaction in CRSwNP patients. CRS patients who achieve near perfect OCES and sinus endoscopy scores after surgery have olfactory metrics that are indistin- guishable from controls regardless of polyp status. CONCLUSIONS The OCES is a valid olfactory-specific measure that demonstrates strong validity and provides complimentary infor- mation to traditional sinus endoscopy to aid in our understanding of OD associated with CRS.

Abstract
BACKGROUND Chronic rhinosinusitis with nasal polyps (CRSwNPs) has several phenotypes. OBJECTIVES The goal of this study was to evaluate computed tomography (CT) findings associated with each CRSwNP phenotype. METHODS Patient charts between January 2015 and March 2019 were retrospectively reviewed. Patient groups, including allergic fungal rhinosinusitis (AFRS), aspirin-exacerbated respiratory disease (AERD), central compartment atopic disease (CCAD) and CRSwNP not otherwise specified (CRSwNP NOS), were determined by standard criteria. The oldest CT scan available was reviewed for Lund-Mackay (LM) score, septal involvement of inflammatory disease, opacification of olfactory clefts, nasal cavity opacification, and oblique positioning of the middle turbinates. Nonparametric analyses of variance were performed with correction for multiple comparisons. RESULTS A total of 356 patients had scans available for review; 80 (23%) patients were categorized into the AFRS group, 101 (28%) in the AERD group, 43 (12%) in the CCAD group, and 132 (37%) in the CRSwNP NOS group. Septal inflammatory involvement and oblique middle turbinate orientation on CT scans was higher in both AERD patients and CCAD patients as compared to AFRS and CRSwNP NOS patients (P < .05). Olfactory cleft opacification was increased in the AERD group compared to all other diagnoses (P < .05). The CCAD group showed lower LM scores compared to all other groups (P < .05), and the AFRS group revealed the greatest differences between left and right LM grades, representing unilaterality of disease (P < .05). CONCLUSION CRSwNP encompasses many subsets of disease, which have varying treatments and intraoperative findings. Preoperative CT findings can be used to differentiate between these groups to improve prediction of diagnoses and patient counseling.

Abstract
OBJECTIVE To phenotype patients with aspirin-exacerbated respiratory disease (AERD) according to the presence of atopy, urticaria and level of peripheral eosinophils. METHODS This study included adult asthmatic patients with AERD followed up at a tertiary hospital. They were classified according to atopy and/or urticaria, assessing clinical and laboratorial differences among the groups in order to identify possible aggravating factors of the disease. RESULTS We included 73 patients, 78.1% being female with a mean age of 54.0 years. Severe asthma was observed in 68.5% and respiratory exacerbation with dipyrone in 67.1% of these patients. They had median total serum IgE of 191.6 IU/mL, mean peripheral eosinophils of 718.5 cells/mm3, and 50.7% were atopic. Urticaria was observed in 32.9% of them, and exacerbations were more often triggered by dipyrone (p = .016). Atopic patients were younger than nonatopic patients (p = .023), and had, on average, higher total serum IgE levels (p = .022). We observed a good correlation between asthma severity and peripheral eosinophils count (r2 = 026; p = .021). CONCLUSIONS In this study, severe asthma was highly prevalent in AERD patients. Likewise, urticaria was quite prevalent and its presence was associated with dipyrone induced hypersensitivity reaction. Atopy was found in half of the patients, with no association with asthma severity. Patients with higher levels of peripheral eosinophils had more severe asthma. Dypirone hypersensitivity may be a marker for concomitant respiratory and cutaneous hypersensitivity reactions.

Abstract
This literature review collates and summarizes recent literature to explore the relationship between chronic rhinosinusitis (CRS) and allergy. The relationship between CRS and allergy is not fully understood. However, current evidence suggests a relationship between allergy and specific endotypes of CRS with nasal polyposis, including allergic fungal rhinosinusitis and central compartment atopic disease. Specific endotypes of CRS with nasal polyps seem to have an association with allergy. More evidence is necessary to better characterize this relationship. Level of evidence: 5.

Abstract
BACKGROUND Respiratory epithelial adenomatoid hamartoma (REAH) is a benign lesion of the sinonasal tract that may mimic more concerning pathology. Clinical factors associated with REAH have not been well characterized. OBJECTIVE To report our findings on patients with this pathologic diagnosis. METHODS A retrospective chart review of patients with REAH between September 2006 and November 2019 was conducted. Data collected included clinical allergic rhinitis and asthma history, additional sinonasal diagnoses, prior sinus surgery, and the location of the REAH within the sinonasal cavity. RESULTS Twenty-six patients were identified (53.8% male, mean age 62 years [range, 29-93]). Bilateral REAH occurred in 50%. REAH was located at the superior nasal septum in 84.6% cases, with the remainder identified in sinus contents submitted for pathology, making definitive site uncertain. Concurrent sinonasal inflammatory disorders were identified in 18 patients (69.2%), including chronic rhinosinusitis with nasal polyps-not otherwise specified (6), chronic rhinosinusitis without nasal polyps (4), aspirin-exacerbated respiratory disease (2), allergic fungal rhinosinusitis (1), central compartment atopic disease (5), and IgG4-related sclerosing disease (1). Eight patients had isolated REAH. Adequate allergy records were available for 19 patients, of which 18 of 19 (94.7%) had clinical allergic rhinitis. CONCLUSIONS REAH is a benign sinonasal lesion commonly located within the central compartment of the nasal cavity, a site of significant allergen exposure. Affected patients have a high incidence of allergy along with chronic inflammatory conditions. The coexistence of REAH within inflammatory nasal mucosa in a consistent anatomic location, suggests REAH may have a similar etiology to central compartment atopic disease, with resultant respiratory glandular ingrowth within long-standing reactive changes of mucosa derived from ethmoid embryologic origin.

Abstract
BACKGROUND Central compartment atopic disease (CCAD) is a recently described variant of chronic rhinosinusitis with nasal polyp (CRSwNP) associated with inhalant allergy. An association with asthma was noted to be uncommon within our clinical practice. The purpose of this study was to determine allergy and asthma prevalence in CCAD and other CRSwNP subtypes. METHODS A retrospective analysis at a tertiary care institution was performed over the period from 2015 to 2019. CRSwNP was grouped into the following subtypes: allergic fungal rhinosinusitis (AFRS); aspirin-exacerbated respiratory disease (AERD); CCAD; and CRSwNP not otherwise specified (CRSwNP NOS). Patients with sinonasal polyps and concomitant polypoid disease in the central compartment (CRSwNP/CC) were analyzed as a separate cohort for the purpose of this study. Prevalence of allergy and asthma was compared between groups. RESULTS Three hundred fifty-six patients were included. CRSwNP NOS was the most common subtype (37.1%) and CRSwNP/CC was the least common (3.7%), with other CRS subtypes ranging between 11.5% and 24.2%. Asthma prevalence was highest in AERD (100%) and CRSwNP NOS (37.1%), but substantially lower in AFRS (19.0%) and CCAD (17.1%). Asthma was significantly more common in AERD and CRSwNP NOS when compared with CCAD (p < 0.001 and p = 0.039, respectively). Prevalence of allergy was significantly higher in AFRS (100%), CCAD (97.6%), CRSwNP/CC (84.6%), and AERD (82.6%) when compared with CRSwNP NOS (56.1%) (p < 0.001). CONCLUSION CCAD represents a clinically distinct phenotype of CRSwNP with a high prevalence of allergy and low prevalence of asthma. Patients with both CCAD and diffuse sinonasal polyps had an allergy prevalence approaching that of CCAD and an asthma prevalence approaching CRSwNP NOS.
