Abstract
OBJECTIVE To evaluate the association between smell loss and other aspects of disease, and evaluate dupilumab efficacy in patients with severe chronic rhinosinusitis with nasal polyps (CRSwNP) and moderate or severe smell loss. METHODS This post-hoc analysis of the SINUS-24/52 studies (NCT02912468/NCT02898454) analyzed nasal polyp score (NPS, 0-8), nasal congestion/obstruction (NC, 0-3), Lund-Mackay CT-scan score (LMK-CT, 0-24), rhinosinusitis severity visual analog scale (RS-VAS, 0-10), and 22-item Sinonasal Outcome Test (SNOT-22, 0-110) according to baseline monthly average patient-reported loss of smell scores (LoS, 0-3) of >1 to 2 (moderate) or >2 to 3 (severe) in patients randomized to dupilumab 300 mg or placebo every 2 weeks. RESULTS Of 724 patients randomized, baseline LoS was severe in 601 (83%) and moderate in 106 (15%). At baseline, severe versus moderate LoS was associated with 1-point greater severity of NC (odds ratio [OR] 6.01 [95% confidence interval, (CI) 3.95, 9.15]), 5-point greater severity of LMK-CT (OR 2.19 [1.69, 2.85]), and 8.9-point greater severity of SNOT-22 (OR 1.35 [1.20, 1.49]). At Week 24, least squares mean differences (95% CI) dupilumab versus placebo in change from baseline were: NPS -1.90 (-2.56, -1.25) and -1.95 (-2.20, -1.70) in the moderate and severe baseline LoS subgroups, respectively; NC -.35 (-.64, -.06) and -1.00 (-1.13, -.87); LMK-CT -6.30 (-7.88, -4.72) and -6.22 (-6.82, -5.63); RS-VAS -1.18 (-2.20, -.16) and -3.47 (-3.90, -3.03); and SNOT-22 -7.52 (-14.55, -.48) and -21.72 (-24.63, -18.82); all nominal P < .05 versus placebo. Improvements with dupilumab in NC, RS-VAS, and SNOT-22 were statistically greater in patients with severe versus moderate baseline LoS. CONCLUSION Significant smell impairment in severe CRSwNP is associated with significant disease (NC, RS-VAS, LMK), health-related quality of life impairment (SNOT-22), asthma, and non-steroidal anti-inflammatory drug-exacerbated respiratory disease. Dupilumab significantly improved NPS, NC, LMK-CT, RS-VAS, and SNOT-22 in subjects with moderate and severe baseline smell loss.

Abstract
Chronic rhinosinusitis (CRS) is a global disease characterized by poor treatment outcomes and high recurrence rates, significantly affecting patients' quality of life. Due to its complex pathophysiology and diverse clinical presentations, CRS is categorized into various subtypes to facilitate more precise diagnosis, treatment, and prognosis prediction. Among these, CRS with nasal polyps (CRSwNP) is further divided into eosinophilic CRSwNP (eCRSwNP) and noneosinophilic CRSwNP (non-eCRSwNP). However, there is a lack of precise predictive diagnostic and treatment methods, making research into accurate diagnostic techniques for CRSwNP endotypes crucial for achieving precision medicine in CRSwNP. This paper proposes a method using multiangle sinus computed tomography (CT) images combined with artificial intelligence (AI) to predict CRSwNP endotypes, distinguishing between patients with eCRSwNP and non-eCRSwNP. The considered dataset comprises 22,265 CT images from 192 CRSwNP patients, including 13,203 images from non-eCRSwNP patients and 9,062 images from eCRSwNP patients. Test results from the network model demonstrate that multiangle images provide more useful information for the network, achieving an accuracy of 98.43%, precision of 98.1%, recall of 98.1%, specificity of 98.7%, and an AUC value of 0.984. Compared to the limited learning capacity of single-channel neural networks, our proposed multichannel feature adaptive fusion model captures multiscale spatial features, enhancing the model's focus on crucial sinus information within the CT images to maximize detection accuracy. This deep learning-based diagnostic model for CRSwNP endotypes offers excellent classification performance, providing a noninvasive method for accurately predicting CRSwNP endotypes before treatment and paving the way for precision medicine in the new era of CRSwNP.

Abstract
Accurate preoperative differentiation of the chronic rhinosinusitis (CRS) endotype between eosinophilic CRS (eCRS) and non-eosinophilic CRS (non-eCRS) is an important topic in predicting postoperative outcomes and administering personalized treatment. To this end, we have constructed a sinus CT dataset, which comprises CT scan data and pathological biopsy results from 192 patients of chronic rhinosinusitis with nasal polyps (CRSwNP), treated at the Second Affiliated Hospital of Shantou University Medical College between 2020 and 2022. To differentiate CRSwNP endotype on preoperative CT and improve efficiency at the same time, we developed a multi-view fusion model that contains a mini-architecture with each network of 10 layers by modifying the deep residual neural network. The proposed model is trained on a training set and evaluated on a test set. The multi-view deep learning fusion model achieved the area under the receiver-operating characteristics curve (AUC) of 0.991, accuracy of 0.965 and F1-Score of 0.970 in test set. We compared the performance of the mini-architecture with other lightweight networks on the same Sinus CT dataset. The experimental results demonstrate that the developed ResMini architecture contribute to competitive CRSwNP endotype identification modeling in terms of accuracy and parameter number.

[PMID: 35771157 DOI: 10.1002/alr.23053] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/29/2022] [Revised: 06/03/2022] [Accepted: 06/22/2022] [Indexed: 01/26/2023]
Abstract
BACKGROUND While various sinus computed tomography (CT) scoring systems have been proposed and used in the literature, no single system has been identified as superior. The strength of associations between CT scoring systems and measures of olfaction also remains unclear. METHODS A systematic review of PubMed, CINAHL, Scopus, and the Cochrane Library was conducted following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. Studies that reported both CT scores and measures of olfaction in a cross-sectional manner were included. RESULTS A total of 37 studies were eligible for meta-analysis. Of 8035 patients with chronic rhinosinusitis, 55.6% were male patients and 53.2% had chronic rhinosinusitis with nasal polyps. Analysis by meta-regression was performed of Lund-Mackay (LM) versus Smell Identification Test-40 (SIT-40; 12 studies), Brief Smell Identification Test (BSIT; 10 studies), Sniffin' Sticks (SS; 10 studies), and Toyota & Takagi (T&T) olfactometry (four studies). A significant moderate association was found between LM and SIT-40 (R2 = 0.612, p < 0.001) and LM and SS (R2 = 0.612, p < 0.001). An association between LM and BSIT approached significance (R2 = 0.461, p = 0.054). No significant associations were noted between LM and T&T olfactometry and between LM and SS when stratified by nasal polyp status. CONCLUSION There is a significant moderate association of current CT scoring systems to SIT-40 and SS. Further research should focus on associations of objective measures of olfaction to CT scores of the nasal cavity, sinuses, and olfactory cleft, as well as other disease markers.

Abstract
Cranial neuropathy can result from pathology affecting the nerve fibers at any point and requires imaging of the entire course of the nerve from its nucleus to the end organ in order to identify a cause. MRI with and without intravenous contrast is often the modality of choice with CT playing a complementary role. The ACR Appropriateness Criteria are evidence-based guidelines for specific clinical conditions that are reviewed annually by a multidisciplinary expert panel. The guideline development and revision process support the systematic analysis of the medical literature from peer-reviewed journals. Established methodology principles such as Grading of Recommendations Assessment, Development, and Evaluation or GRADE are adapted to evaluate the evidence. The RAND/UCLA Appropriateness Method User Manual provides the methodology to determine the appropriateness of imaging and treatment procedures for specific clinical scenarios. In those instances in which peer-reviewed literature is lacking or equivocal, experts may be the primary evidentiary source available to formulate a recommendation.

Abstract
BACKGROUND Loss of smell (LoS) is one of the most troublesome and difficult-to-treat symptoms of severe chronic rhinosinusitis with nasal polyps (CRSwNP). OBJECTIVE To assess the impact of dupilumab on sense of smell in severe CRSwNP. METHODS In the randomized SINUS-24 and SINUS-52 studies, adults with severe CRSwNP received dupilumab 300 mg subcutaneously or matching placebo every 2 weeks for 24 or 52 weeks, respectively. Smell was assessed using daily patient-reported LoS score (0-3) and University of Pennsylvania Smell Identification Test (UPSIT; 0-40). Data from the 2 studies were pooled through week 24. Relationships between patient phenotypes and smell outcomes were also assessed. RESULTS We randomized 724 patients (286 placebo, 438 dupilumab); mean CRSwNP duration was 11 years; 63% had prior sinonasal surgery. Mean baseline LoS was 2.74. Dupilumab produced rapid improvement in LoS, evident by day 3, which improved progressively throughout the study periods (least squares mean difference vs placebo -0.07 [95% CI -0.12 to -0.02]; nominal P < .05 at day 3, and -1.04 [-1.17 to -0.91]; P < .0001 at week 24). Dupilumab improved mean UPSIT by 10.54 (least squares mean difference vs placebo 10.57 [9.40-11.74]; P < .0001) at week 24 from baseline (score 13.90). Improvements were unaffected by CRSwNP duration, prior sinonasal surgery, or comorbid asthma and/or nonsteroidal anti-inflammatory drug-exacerbated respiratory disease. Baseline olfaction scores correlated with all measured local and systemic type 2 inflammatory markers except serum total immunoglobulin E. CONCLUSIONS Dupilumab produced rapid and sustained improvement in sense of smell, alleviating a cardinal symptom of severe CRSwNP.

Abstract
OBJECTIVE This study evaluated the post-operative indications for sinonasal topical steroid treatment using a corticosteroid (steroid)-eluting, sinus-bioabsorbable device and its effects in patients with eosinophilic chronic rhinosinusitis. METHOD Post-operative courses were investigated in two groups: group A with patients who underwent sinonasal topical steroid treatment, and group B with control patients who did not. RESULTS Group A was significantly younger than group B (p < 0.01), and the pre-operative computed tomography score was significantly higher in group A than in group B (p < 0.05). In the post-operative stage, the nasal symptoms questionnaire component of olfactory loss and the post-operative endoscopic appearance score were significantly worse in group A than in group B (p < 0.01). CONCLUSION These data suggest that younger age, more severe rhinosinusitis and post-operative olfactory loss led to the need for sinonasal topical steroid treatment to prevent relapsing inflammation after functional endoscopic sinus surgery in patients with eosinophilic chronic rhinosinusitis.

Abstract
Background Eosinophilic (Eos) and non-eosinophilic (non-Eos) chronic rhinosinusitis with nasal polyps (CRSwNP) react differently to clinical treatment, with eosinophilic chronic rhinosinusitis with nasal polyps (Eos CRSwNP) being more likely to recur after surgery. Objective To explore the clinical value of the visual analog scale (VAS), nasal endoscopy score (Lund–Kennedy, L–K), computed tomography (CT) score (Lund–Mackay scoring system, L–M), and blood Eos percentage in the differential diagnosis of Eos CRSwNP and non-Eos CRSwNP. Methods Ninety-nine patients with CRSwNP were enrolled in this study and assigned to 2 groups (Eos CRSwNP and non-Eos CRSwNP). The blood Eos percentage and VAS, L–K, and L–M scores in the 2 groups of patients were compared. A receiver operating characteristic (ROC) was used to assess the usefulness of VAS, L–K, and L–M scores for differentiating Eos CRSwNP and non-Eos CRSwNP. Results There were significantly differences between the Eos CRSwNP group and non-Eos CRSwNP group in the following scores: blood Eos percentage, mean VAS score, olfaction/VAS, general discomfort/L–K, edema score/L–K, olfactory cleft (OC) score via endoscopy, mean L–M score, anteriorethmoid sinus score, posterior ethmoid sinus score, sphenoid sinus score, frontal sinus score, and OC score via CT. An ROC analysis showed that blood Eos percentage had the highest area under the ROC curve (AUC) value (0.749); however, several other scores (olfaction score/VAS, edema score/L–K, and mean L–M score) also had high AUC values. The combination of olfaction score/VAS and blood Eos percentage had the highest clinical convenience score as well as high sensitivity and specificity. A combination of cutoff values for the 2 predictors (blood Eos percentage ≥3.85%, olfaction score/VAS score ≥3) showed a sensitivity of 75.5% and a specificity of 78.0%. Conclusion The olfaction score/VAS score and the blood Eos percentage can be combined to differentiate Eos CRSwNP from non-Eos CRSwNP in a Chinese population.

Abstract
OBJECTIVE This study aimed to determine the predictors of disease progression after functional endoscopic sinus surgery in patients with chronic rhinosinusitis. METHOD A total of 281 adult chronic rhinosinusitis patients who underwent primary bilateral functional endoscopic sinus surgery between 2007 and 2017 and had at least 12 months of follow-up endoscopic evaluation were examined. Patients were divided into eosinophilic (n = 205) and non-eosinophilic chronic rhinosinusitis groups (n = 76). In order to determine adverse factors, post-operative endoscopic appearance scores were analysed in relation to the pre- and intra-operative findings using multiple regression analyses. RESULTS The post-operative course of eosinophilic cases deteriorated over time, like the early period for non-eosinophilic cases. Frontal sinus polyps recurred early in eosinophilic chronic rhinosinusitis. Multivariate analyses indicated young adulthood, asthma, high computed tomography score and frontal sinus polyps as significant adverse predictors. CONCLUSION Early, appropriate estimation of sinonasal conditions appears to be crucial for successful surgical management of chronic rhinosinusitis.

Abstract
OBJECTIVES We aimed to verify the usefulness of our proposed nasal symptom questionnaire (NSQ) scoring system and to determine predictors linked to the improvement in nasal symptoms in chronic rhinosinusitis (CRS) patients undergoing endoscopic sinus surgery (ESS). PATIENTS AND METHODS Ninety-one CRS patients undergoing ESS and 144 volunteers with results of NSQ available were enrolled. The NSQ consists of 10 items. Receiver-operating-characteristic (ROC) curve, area under the ROC curve (AUC), internal consistency, and test-retest reproducibility of the NSQ were analyzed. The relationship of the NSQ score with the visual analogue scale (VAS) was examined. After classifying into two groups, i.e., (i) "improvement group" and (ii) "no-improvement group," factors linked to the improvement in NSQ after ESS were investigated. RESULTS ROC-AUC (0.9318), the Cronbach α coefficient (0.8696), and the test-retest coefficient (0.8131) showed high reliability. NSQ score significantly correlated with VAS in both pre- (p < 0.0001, rs = 0.6007) and postoperative stages (p < 0.0001, rs = 0.5975). The postoperative NSQ scores significantly decreased compared with baseline levels (p < 0.0001). In multivariate analysis, the computed tomography (CT) score by the Lund-Mackay scoring system revealed to be significant (p = 0.0481). CONCLUSION Our proposed NSQ scoring system was well verified. The CT score can be helpful for predicting the improvement in nasal symptoms after ESS in CRS patients.

Abstract
Olfactory dysfunction is a major symptom reported by patients with chronic rhinosinusitis (CRS). Surgical treatment of this disease requires close surveillance of such dysfunction because of wide ranging implications for safety, quality of life, and impact on the flavor of foods and beverages. This review highlights key findings regarding the influences of endoscopic sinus surgery (ESS) on olfactory function across the unique presentations of CRS. Such findings provide information useful for informing patients of potential complications and for obtaining informed consent prior to surgical intervention. ESS has been shown to improve olfaction across all types of CRS as assessed through quantitative testing and subjective reports. The presence of nasal polyposis (NP) and eosinophilia have been identified as predictors of significant postoperative olfactory improvement. When indicated, judicious partial resection of the middle turbinate may result in improved olfactory function without a risk of long term complication. Careful attention to the olfactory cleft and frontal sinus recess are important in limiting olfactory complications by avoiding indiscriminate disruption of olfactory epithelium. Given the chronic nature of the disease, surveillance of olfactory function in patients with CRS is a lifelong activity that will evolve as emerging technologies become available.

Abstract
OBJECTIVE This study aimed to analyse findings of functional endoscopic sinus surgery to estimate the post-operative course of patients with chronic rhinosinusitis. METHODS From 2007 to 2015, 291 adult patients with bilateral chronic rhinosinusitis, divided into eosinophilic chronic rhinosinusitis (n = 210) and non-eosinophilic chronic rhinosinusitis (n = 81) groups, who underwent primary functional endoscopic sinus surgery were enrolled. Functional endoscopic sinus surgery findings, scored as operating score, were analysed in relation to pre-operative olfactory recognition threshold and sinonasal computed tomography imaging score, as well as post-operative endoscopic appearance. RESULTS Operating scores in eosinophilic chronic rhinosinusitis were significantly worse than those in non-eosinophilic chronic rhinosinusitis. The anterior ethmoid sinus and superior meatus were predominantly inflamed. Operating score significantly correlated with pre-operative olfaction recognition threshold, computed tomography score and pre-operative endoscopic appearance score. In eosinophilic chronic rhinosinusitis, higher operating scores were related to post-operative deterioration of endoscopic appearance score. CONCLUSION The operating score reflects the course following functional endoscopic sinus surgery. Patients with more severe operative findings require longer post-operative treatment.

Olfactory cleft evaluation: a predictor for olfactory function in smell-impaired patients? Eur Arch Otorhinolaryngol 2018; 275:1129-1137. [PMID: 29488006 DOI: 10.1007/s00405-018-4913-8] [Citation(s) in RCA: 11] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/09/2017] [Accepted: 02/21/2018] [Indexed: 10/17/2022]
Abstract
OBJECTIVE In this study, we introduce an extension of previous work by Soler et al. (Int Forum Allergy Rhinol 6(3):293-298, 2016) on a modified endoscopic scoring system of the Lund-Kennedy Score (focusing on the olfactory cleft) to evaluate its correlation with the olfactory function in patients with various smell disorders. STUDY DESIGN A prospective cohort study. METHODS Two-hundred and eighty-eight participants were included and categorized in five groups according to the cause of their olfactory disorder: (0) control, (1) idiopathic, (2) sino-nasal, (3) postinfectious and (4) post traumatic olfactory loss. Olfaction was evaluated using the "Sniffin' Sticks" test. The classical Lund-Kennedy scoring and a new olfactory cleft specific Lund-Kennedy scoring (OC-LK) were performed to evaluate mucosal changes. RESULTS Significantly higher OC-LK scores on both sides were found in smell-impaired patients as compared to normosmic controls. When comparing the 4 groups, a significant difference of the OC-LK score were present between the sino-nasal and all other groups. Most importantly, significant negative correlations with strong effects were shown in the sino-nasal group between the OC-LK score and odor discrimination and odor identification. However, no such correlation emerged between the classical LK score and smell function. CONCLUSION Olfactory cleft evaluation using the OC-LK score correlates with the olfactory function in patients with sino-nasal smell disorder. This diagnostic tool may reflect the underlying pathophysiological mechanism of sino-nasal smell loss, and therefore, should complement olfactory diagnostics in patients with sino-nasal smell disorder.
