Endoscopic Sinus Surgery In Patients Research Articles

Evolving Utilization of Topical Budesonide Following Endoscopic Sinus Surgery.

Topical budesonide irrigations are frequently prescribed after endoscopic sinus surgery (ESS) to manage mucosal inflammation. However, this off-label indication may conflict with health insurance formularies. We sought to quantify the relative frequency of postoperative budesonide prescriptions to determine if this could be considered common practice after ESS. We extracted and analyzed postoperative prescription data for patients undergoing ESS from 2016 to 2022 within our health care system. Overall, among 8157 ESS patients, 15.9% and 22.1% received topical budesonide prescriptions within 30 or 180 days postoperatively, respectively. On a year-over-year basis, budesonide prescription frequency increased significantly over time, culminating at 20.3% and 24.9% in 2022. Conversely, postoperative oral corticosteroid (OCS) prescriptions showed a decreasing frequency over the same time period (P < .001). Our results show topical budesonide irrigations are increasingly frequently prescribed after ESS and may offset postoperative OCS requirements. This argues for coverage of topical budesonide as a formulary medication after ESS.

Evaluating the efficacy of nasal irrigation in postoperative functional endoscopic sinus surgery patients: a systematic review and meta-analysis.

Functional endoscopic sinus surgery (FESS) is a mainstay surgical intervention for chronic rhinosinusitis with nasal polyposis (CRSwNP). Nasal irrigation, particularly with normal saline, is a widely recommended postoperative care modality. This systematic review and meta-analysis aimed to assess the efficacy of various nasal irrigation solutions in postoperative FESS patients. A comprehensive search was conducted in multiple databases for randomized controlled trials investigating normal saline and various substances for nasal irrigation post-FESS. The systematic review followed PRISMA guidelines, and the meta-analysis used R software for data synthesis. Outcome measures included SNOT-22 and LKES scores. The Cochrane tool was employed to evaluate the potential for bias. Results from 14 studies, focusing on six each for SNOT-22 and LKES, revealed a significant reduction in symptoms and endoscopic scores with various solutions compared to normal saline. The meta-analysis using the random-effects model indicated a negative standardized mean difference (SMD) of - 0.69(95% CI [- 1.64; 0.27], p = 0.157) for symptoms and endoscopic scores (SMD = - 0.48, 95% CI [- 1.32; 0.36], z = - 1.12, p = 0.264). Subgroup analyses highlighted budesonide's efficacy over normal saline, but substantial heterogeneity and potential publication bias were noted. Nasal irrigation with various solutions postoperative FESS patients demonstrated significant improvements in patient-reported symptoms and endoscopic scores compared to normal saline. Budesonide appeared particularly effective. However, high heterogeneity and potential publication bias warrant cautious interpretation. Standardized outcome measures and further research are needed to strengthen the evidence.

Biofilm-producing Bacteria and Quality of Life after Endoscopic Sinus Surgery in Patients with Chronic Rhinosinusitis with Nasal Polyposis.

Chronic rhinosinusitis (CRS) is one of the most common health disorders in humans and has a major impact on health-related quality of life (HRQoL). Of the many factors contributing to the etiology of CRS, less is known about the correlation between CRS and bacterial biofilms and their impact on HRQoL. The aim of this prospective study was to investigate the relationship between biofilm-producing bacteria and patients' objective findings and HRQoL. Forty-eight patients with CRSwNP were enrolled in a 12-month prospective study. The Lund-Mackay (LM) CT and endoscopic Lund-Kennedy (LK) scores were obtained before endoscopic sinus surgery (ESS), and patients completed the HRQoL instruments: the 22-item Sinonasal Outcome Test (SNOT-22), the 36-item Short Questionnaire (SF-36), and the visual analog scale (VAS). A sinus culture was obtained at ESS, bacteria were isolated, and in vitro quantification of the biofilm was performed. The LK score and HRQoL were determined postoperatively at months 1, 3, 6, and 12. The most common bacterial isolates in patients with CRSwNP were Staphylococcus aureus (28%), coagulase-negative staphylococci (52%), and Pseudomonas aeruginosa (8%). Preoperatively, the highest LM and LK scores were found in patients with strong biofilm producers. Postoperative LK scores were significantly reduced in all patients. Postoperative VAS scores were significantly reduced from month 1 to month 12 postoperatively. Patients with strong biofilm producers had significantly worse nasal blockage, secretion, headache, facial pressure and pain, and loss of smell preoperatively, compared to patients with low biofilm producers. The most significant reduction in preoperative scores SNOT-22 and SF-36 (excluding physical functioning) was seen in patients with S. aureus and P. aeruginosa. Patients with strong biofilm producers had higher LK and LM scores preoperatively, and greater improvement in LK and HRQoL scores postoperatively. Microbiologic surveillance of all CRS patients is recommended.

Adherence to guidelines prior to endoscopic sinus surgery in patients with chronic rhinosinusitis and asthma.

Optimal care for patients with simultaneous chronic rhinosinusitis (CRS) and asthma is often complicated due to interaction between these conditions. This study depicts the lack of attention to asthma within the otorhinolaryngological field, and the relationship between CRS and asthma, including the risk of revision surgery in such patients. A retrospective cohort study was conducted on patients undergoing functional endoscopic sinus surgery (FESS) because of CRS with nasal polyps (CRSwNP) and without nasal polyps in a five-year period. Patients were examined for adherence to guidelines, asthma, revision FESS, allergies and septo-/turbinoplasty. Results were compared to international reports. A total of 589 patients had FESS because of CRS of whom 203 (34.5%) had co-existing asthma. A higher risk of asthma (relative risk (RR) = 1.82 (95% confidence interval (CI): 1.29-2.56), p less-than 0.001) and revision FESS (RR = 2.20 (95% CI: 1.33-3.65), p less-than 0.001) was found in patients with CRSwNP. Attention to asthma was poor in patients with no asthma diagnosis before referral. Asthma was lower in the study population than in the literature. Danish national guidelines on CRS management are insufficient regarding attention to asthma. Results call attention to the need for more multidisciplinary team management. None. Not relevant.

The safety and efficacy of spray cryotherapy after endoscopic sinus surgery in chronic rhinosinusitis: A systematic review of randomized controlled trials

Background Chronic rhinosinusitis (CRS) is a condition that affects 5–12% of the general population. Endoscopic sinus surgery (ESS) is the preferred treatment because of its few adverse effects. The most common post-operative consequences include synechia, nasal blockage, and disease recurrence. Spray cryotherapy is a novel therapeutic approach with promising outcomes for the treatment of upper airway disorders. This review aimed to investigate the effects of spray cryotherapy (SCT) following ESS in patients with chronic rhinosinusitis. Methods Six electronic databases were searched for randomized clinical trials (RCTs). The selected trials were evaluated for methodological quality, and data were extracted by two independent reviewers. The Cochrane risk-of-bias tool was used to assess the quality of evidence. Results Three RCTs with 85 patients were included in the final analysis. SCT was related to -16 and -77 reductions in Lund-McKay and SNOT-22 scores after 36 weeks of follow-up, in contrast to a placebo, which showed -10.4, -65. Regarding the side effects of SCT, no adverse effects were reported, and visual assessments showed no pain, visual field loss, or any other ocular complications. Conclusions SCT is a new treatment modality after endoscopic sinus surgery that shows an effective post-operative management strategy with better post-operative scales (Lund-McKay, SNOT-22, POSE, and Lund-Kennedy) and less edema, obstruction, crusting, and inflammation with minimal or no side effects. However, further research with longer follow-ups, a larger sample size, and subjective assessment is needed to assess any possible long-term side effects.

Multivariate analysis of clinical and radiological risk factors for revision endoscopic sinus surgery in patients with chronic rhinosinusitis with nasal polyps: can phenotype predict recurrence?

This study aimed to analyse clinical and radiological features (phenotypes) to predict revision risk after functional endoscopic sinus surgery in patients with chronic rhinosinusitis with nasal polyps. Phenotype characteristics of the patients with chronic rhinosinusitis with nasal polyps who underwent functional endoscopic sinus surgery were analysed retrospectively. The rates of asthma, aspirin sensitivity, smoking and a positive prick test result were significantly higher in revision functional endoscopic sinus surgery cases (p < 0.001, 0.001, < 0.001 and < 0.001, respectively). Multivariate analysis demonstrated that only gender, pre-operative nasal steroid use, pre-operative systemic steroid use, intra-operative systemic steroid use and smoking were significant risk factors for revision functional endoscopic sinus surgery (p = 0.034, 0.001, 0.010, 0.007 and 0.001, respectively). In addition, only eosinophilia and aspirin sensitivity were significant risk factors for multiple revision functional endoscopic sinus surgery procedures (p = 0.043 and 0.005, odds ratio = 2.4 and 5.2). Beyond the endotype of chronic rhinosinusitis with nasal polyps, defining clinical and radiological factors enables a valid prediction of patients at high risk of revision functional endoscopic sinus surgery.

Association of Comorbid Asthma and the Efficacy of Bioabsorbable Steroid-eluting Sinus Stents Implanted After Endoscopic Sinus Surgery in Patients with Chronic Rhinosinusitis with Nasal Polyps

ObjectiveTo identify factors affecting the efficacy of steroid-eluting sinus stents implanted after endoscopic sinus surgery (ESS) in patients with chronic rhinosinusitis with nasal polyps (CRSwNP).MethodsWe performed a post-hoc analysis of a randomized self-controlled clinical trial on post-operative implantation of bioabsorbable steroid-eluting stents in patients with CRSwNP. Univariate logistic regression analysis was conducted to identify which of the following factors affect the response to post-operative stent implantation: sex, serum eosinophil levels, history of prior surgery, endoscopic scores, and comorbid conditions (asthma and allergic rhinitis). The primary outcome was the rate of post-operative intervention on day 30, and the secondary outcome was the rate of polypoid tissue formation (grades 2–3) on days 14, 30, and 90.ResultsA total of 151 patients with CRSwNP were included in the post-hoc analysis. Asthma was identified as the only risk factor for a poor response to steroid-eluting sinus stents on post-operative day 30, with an odds ratio of 23.71 (95% CI, 2.81, 200.16; P=0.004) for the need for post-operative intervention and 19 (95% CI, 2.20, 164.16; P=0.003) for moderate-to-severe polypoid tissue formation. In addition, the asthmatic group showed higher rates of post-operative intervention and polypoid tissue formation than the non-asthmatic group on post-operative day 30. Blood eosinophil levels were not identified as a risk factor for poor outcomes after stent implantation.ConclusionComorbid asthma, but not blood eosinophil level, impairs the efficacy of steroid-eluting sinus stents in the short term after ESS in patients with CRSwNP.

Assessment of Correlation Between Disease Specific Quality of Life and Endoscopy Score After 1Month and 6Months of Endoscopic Sinus Surgery (ESS) in Patients with Chronic Rhinosinusitis: A Prospective Study.

Rhinosinusitis is a prevalent condition worldwide affecting the developed and the third world countries alike. SNOT-22 is a validated disease-specific questionnaire designed to use in Chronic Rhino Sinusitis (CRS), which means to quantify patients perception of their disease burden. SNOT 22 questionnaire can chart patients nasal as well as psychological symptoms arising due to CRS and very well become marker of individual symptomatic improvement. To study the correlation between disease specific quality of life and endoscopy score after 1month and 6months of Endoscopic Sinus Surgery in patients with Chronic Rhinosinusitis. In the present study, ESS surgery showed improvement in Endoscopy score and all the symptoms assessed by SNOT-22. The total percentage of improvement in the SNOT-22 score was 70% after 1month and 89% at the end of 6months. We conclude that after the procedure of ESS not only endoscopic evaluation is necessary but also psychological and symptomatic assessment by SNOT 22 is very necessary as nasal and psychological factors were equally decisive for the seeking of the treatment (pharmacological/surgical) by the patient.

Risk Factors for Recurrence of Nasal Polyps after Endoscopic Sinus Surgery in Patients with Allergic Chronic Rhino Sinusitis.

Rhino sinusitis, is a common inflammatory disease that affects the nasal cavity and paranasal sinuses in millions of individuals. Chronic sinusitis patients complain of a combination of nasal obstruction, rhinorrhea, post nasal drip and facial pain. To identify the risk factors of the recurrence of nasal polyps in chronic rhino sinusitis patients after endoscopic sinus surgery. After a review of 60 patients with chronic rhino sinusitis with failed medical treatment requiring FESS presenting in Kasr Alainy Hospital in Cairo University and October 6 University Hospital from May 2022 to March 2023. All patients were subjected to history taking, clinical examination including endoscopy, subjective evaluation of symptoms and CT-scan. Of our patients, six patients (15%) were diagnosed with recurrence of nasal polyps with chronic rhino sinusitis and needed revision surgery. There are multiple risk factors related to the recurrence of nasal polyps including smoking followed by having a history of an asthma, the presence of an allergy, septal deviation, prior sinus surgery, and turbinate hypertrophy. Other factors, as proper medical treatment such as topical steroids and treatment of allergy had a significant role in decreasing the recurrence rate. Risk factors related to the recurrence of nasal polyps should be avoided before surgery. The avoidance of risk factors protects the patients from the recurrence of nasal polyps, the hazards of anaesthesia on surgical treatment, and the financial cost of surgery. Follow up is important in the prevention of recurrence of nasal polyps and improves the symptoms.

Rates of Antidepressant, Anxiolytic, and ADHD Medication Use Among Patients Undergoing ESS.

Patients with chronic rhinosinusitis (CRS) are estimated to have psychiatric comorbidity at a higher rate than the general population; however, self-report of depression diagnoses or symptoms often underestimates true prevalence in many populations. In the present study, a cohort of 2279 patients undergoing endoscopic sinus surgery (ESS) were matched to an equal number of non-CRS control subjects by age, sex, race and health status. Overall, the rate of antidepressant/anxiolytic utilization among ESS patients was 22.1%versus 11.3% for controls (P < .001, OR = 2.23, 95% CI 1.90-2.63). The rate of ADHD medication utilization among ESS patients was 3.6%versus 2.0% for controls (P = .001, OR = 1.85, 95% CI 1.28-2.68). This study suggests that patients undergoing ESS exhibit significantly higher rates of antidepressant and ADHD medication utilization relative to a matched control population.

Cost–utility analysis of dupilumab compared with endoscopic sinus surgery in patients with chronic rhinosinusitis with nasal polyps. Evaluation in Colombia, a developing country

ABSTRACT Introduction Chronic rhinosinusitis with nasal polyps (CRSwNP) compromises respiratory function, sleep, concentration, work capacity, and quality of life, generating high costs for patients and health systems. The aim of the study was to analyze the cost utility of Dupilumab compared to endoscopic sinus surgery for patients with CRSwNP. Research design and methods We developed a model-based cost–utility analysis from the perspective of the Colombian health system to compare Dupilumab vs. endoscopic nasal surgery in patients with difficult-to-treat CRSwNP. Transition probabilities were extracted from the published literature about CRSwNP, and costing was based on local tariffs. We performed probabilistic sensitivity analysis for outcomes, probabilities, and costs (10.000 Monte Carlo simulations). Results The cost of dupilumab ($ 142.919) was 7.8 times higher than nasal endoscopic sinus surgery ($ 18.347). In terms of quality-adjusted life years (QALYs), surgery generates better results than Dupilumab: 11.78 vs. 9.05 QALYs. Conclusions From the perspective of the health system, endoscopic sinus surgery for the management of CRSwNP is a dominant alternative in all the analyzed scenarios compared to the use of Dupilumab. From a cost–utility point of view, the use of dupilumab should be considered when the patient requires multiple surgeries or when there is a contraindication for surgery performance.

The centripetal endoscopic sinus surgery in patients with cystic fibrosis: A preliminary study

ObjectivesThe main aim of this study is to analyze the possible differences between clinical, demographic or genetic characteristics, in Cystic Fibrosis (CF) patients with chronic rhinosinusitis (CRS) with different phenotype. The secondary objective is to describe the possible benefit of surgery with Centripetal Endoscopic Sinus Surgery (CESS). MethodsThe study includes 56 who performed CT scan of the paranasal sinuses. They were divided in 3 group according to phenotype: CRS without Nasal Polyps (NP); CRS with NP; CRS complicated with Mucocele. The clinical symptoms, age, gender, genotype, microbial colonization and pulmonary disease stage were collected and analyzed to assess possible statistically significant differences. Regarding the 7 patients who performed CESS surgery, the number of hospitalizations, intravenous (iv) antibiotic courses, respiratory exacerbations, the FEV1, the Lund-Mackay Score (LMS) and the SNOT 22 were evaluated before and 1 year after surgery. ResultsNo statistically significant differences regarding clinical symptoms between the 3 groups were identified (p > 0.05). Furthermore, there were no differences in age, gender, genotype, microbial colonization and pulmonary disease stage (p > 0.05). Regarding the patients who performed CESS, no significative difference in FEV1 progression was found. A reduction in hospitalization, pulmonary exacerbation and in the number of iv antibiotic courses resulted statistically significant different (p = 0.004; <0.001 and <0.001 respectively). A significant improvement in SNOT-22 and LMS (p < 0.001) was obtained. ConclusionRadiological monitoring of the rhinosinus disease is necessary regardless of the clinical expression of the disease. The presence of CRS with NP complicated by mucocele is frequent and independent of the patient's age and clinical manifestations. An extensive surgical approach could represent the gold standard for patients with CF in consideration of the potential important advantages to perform a total toilet of all the sinuses and nasal cavities and at the same time eliminating a potential microbiological reservoir.

Endoscopic sinus surgery outcomes in patients with chronic rhinosinusitis and immunoglobulin deficiencies

BackgroundPatients with chronic rhinosinusitis (CRS) and immunoglobulin deficiencies (ID) have more recalcitrant sinonasal disease and a subset of these patients undergo surgical management for their CRS. However, there is a paucity of literature on the surgical outcomes in this patient population and appropriate treatment algorithms for CRS in patients with ID. The objective of this study was to better elucidate the outcomes of endoscopic sinus surgery (ESS) in patients with ID in terms of disease-specific quality-of-life scores and the need for revision surgery.MethodsA case–control study was performed comparing adult patients with ID and healthy controls that had undergone ESS for CRS. Patients were matched based on age, sex, CRS phenotype, and preoperative Lund-Mackay score. The revision surgery rates, time to revision surgery, and changes in sinonasal outcome tests (SNOT-22) were evaluated.ResultsThirteen patients with CRS and ID were matched to 26 control patients with CRS. The revision surgery rate for cases and controls was 31% and 12%, respectively, but there was no statistical difference (p > 0.05). There was a clinically meaningful reduction in SNOT-22 scores in both groups from the preoperative to postoperative period [mean of 12 points in patients with ID (p = 0.323) and 25 points in controls (p < 0.001)], however, there was again no significant difference between cases and controls (p > 0.05).ConclusionOur data suggests that patients with ID have clinically meaningful improvement in SNOT-22 scores after ESS but may have higher revision rates than immunocompetent patients with CRS. ID are rare disease entities, thus most attempts at studying this cohort would be limited by sample size. Further homogenous data on immunoglobulin deficient patients is required for future meta-analysis to better understand the impact of ESS in patients with ID.

Efficacy of preventive nalbuphine and dexmedetomidine analgesia for post-operative pain in endoscopic sinus surgery: A randomized controlled study

Background: Chronic sinusitis, nasal polyps, and other sinus-related illnesses are common conditions that can be treated with endoscopic sinus surgery (ESS). However, some patients may experience pain or discomfort after the procedure. Pre-emptive analgesia is a method used to reduce post-operative discomfort and the need for painkillers. Recently, there has been growing interest in studying the potential use of nalbuphine and dexmedetomidine as preventative analgesics in ESS. Aims and Objectives: This study aimed to determine the effectiveness of nalbuphine and dexmedetomidine in reducing post-operative pain and opiate use in ESS patients, a randomized controlled trial. Materials and Methods: Ninety patients were randomly selected and given nalbuphine, dexmedetomidine, or a placebo before anesthesia induction. Pain ratings, opioid use, and adverse effects were monitored during the post-operative period. Results: The results showed that both nalbuphine and dexmedetomidine significantly reduced post-operative pain ratings and opioid usage compared to the placebo. Dexmedetomidine was found more effective than nalbuphine in reducing pain, and patients who received it experienced less nausea and vomiting in the first few days after surgery. However, the occurrence of sedation or respiratory depression was not significantly different among the groups. Conclusion: The study concludes that nalbuphine and dexmedetomidine can effectively reduce post-operative pain and opiate use in ESS patients as preventative analgesia. Dexmedetomidine may be a better option due to its superior analgesic effect and lower incidence of nausea and vomiting. These findings may lead to improved pain management and patient satisfaction following ESS procedures.

Voice quality changes after functional endoscopic sinus surgery in patients with nasal polyps

Nasal polyps are associated with hyponasality. The effect of functional endoscopic sinus surgery (FESS) on voice quality has not been adequately investigated; therefore, this study developed objective and subjective measurements to compare nasal polyp patients pre- and postsurgery. An observational prospective study was conducted at Srinagarind Hospital, Khon Kaen University, Thailand. Bilateral nasal polyposis patients who underwent FESS between August 1, 2015 and August 1, 2017, were recruited. All participants were assessed for nasal polyp grade, nasometry, acoustic parameters, acoustic perception, and patient satisfaction before surgery and at the 1-, 3- and 6-month follow-ups. Forty-six patients, 29 males and 17 females (mean age 48.2years ± 16.2years), were enrolled. Mean nasometry scores were significantly improved at 1, 3 and 6months after surgery (p < 0.05), whereas the acoustic parameters were not significantly different after surgery (p > 0.05). Overall acoustic perception, assessed with a set of words and sentences, showed significant improvement in hyponasality voice after surgery (p < 0.05), whereas GIRBAS showed no significant change after surgery in each parameter of perception (p > 0.05). Patient satisfaction with voice changes after surgery was high, with significantly increased mean scores between the 1- and 6-month follow-ups (p < 0.05). The results showed that FESS for nasal polyposis patients improved voice quality and patients' voice satisfaction ratings. Trial registration: This trial was registered at the Thai Clinical Trial Registry (TCTR20210324004).

The effectiveness of platelet rich plasma therapy in chronic sinusitis patients with odor disorder undergoing endoscopic sinus surgery

Objectives: In this study, the objective was to compare the effectiveness of fluticasone dipropionate and platelet-rich plasma treatments added to the treatment in patients undergoing functional endoscopic sinus surgery in patients with chronic sinusitis involving odor dysfunction, different stages and types of sinusitis. Methods: The study included a total of 60 patients between 18 and 60 years who underwent endoscopic sinus surgery due to chronic paranasal sinus infection followed by olfactory dysfunction. Group 1: paranasal sinus surgery + steroid therapy (first 30 patients) and Group 2: paranasal sinus surgery + steroid therapy + PRP therapy (second 30 patients) were grouped together without the patients' knowledge of the operating physician and of the treatment protocol. For the paranasal sinus CT evaluation, Lund-Mackey staging was used and the degree of the disease was determined using the Kennedy staging system. Modified Sniffin Stick test was applied to all patients in the preoperative 1st week and in the 3rd month postoperatively. The Modified Sniffin Stick test was conducted on all patients during the preoperative 1st week and the postoperative 3rd month. The modified Sniffin Stick test and endoscopic evaluation score were evaluated and whether or not the patients benefited from PRP treatment were compared. Results: According to the postoperative endoscopy score, there was a difference between the experimental group and the control group in terms of postoperative endoscopy score, and it was found to be statistically significant. Besides, the postoperative endoscopy score of the experimental group was found to be lower than the control group. The average of Modified Sniffin’ Stick Test scores in the postoperative period of the patients in the study was 28.27 ± 7.88 for the experimental group, while it was determined as 20.08 ± 5.75 for the control group, and this difference was statistically significant. The average anosmia times of the experimental and control group patients in the study were compared, and the mean duration of anosmia was 48.53 ± 20.40 (6-96) for the experimental group and 44.27 ± 19.45 (6.96) for the control group. The difference in the mean duration of anosmia between the experimental and control groups was not found statistically significant. Conclusions: In this research, PRP, which is applied to functional endoscopic sinus surgery and fluticasone dipropionate treatment, has been shown to be a readily applicable, safe and highly efficient method of treatment in patients with chronic sinusitis accompanied by smell dysfunction.

Effect of Topical Furosemide Efficacy on Reducing Bleeding and Quality of Surgical Field During Endoscopic Sinus Surgery in Patients with Chronic Rhinosinusitis.

Introduction:Bleeding during endoscopic sinus surgery has an unfavorable effect on the surgical field and prolongs the time of surgery. In this study, we assessed the efficacy of topical furosemide on bleeding and the quality of the surgical field during endoscopic sinus surgery.Materials and Methods:In this clinical trial, 76 patients with chronic rhinosinusitis were selected for endoscopic sinus surgery and randomly assigned to two groups, topical furosemide (intervention) and normal saline (control). The intervention group received 20 micrograms of intranasal spray twice daily, and the control group received regular intranasal saline spray, similar to the intervention group. In addition, the quality of the surgical field (scoring by the BOEZAART grading system) and the amount of bleeding during surgeries were measured. All data were analyzed.Results:In the intervention and control groups, the mean surgical bleeding volume was 187.70± 24.79 and 229.21± 28.18 ml (P <0.001), the mean of Boezaart scale 2 and 3 (P <0.001) and the mean of surgical time were 106.53±14.67 and 126.63 ± 15.42 minutes (P <0.001), respectively. In patients of the intervention group with and without polyps, the mean surgery time was 99.56± 12.15 and 118.84 ±10.03 minutes (P <0.001), and the mean bleeding volume during endoscopic sinus surgery was 176.46 ± 22.58, 208.46 ±12.14 ml (P <0.001) respectively.Conclusions:Our findings showed that nasal, topical furosemide spray significantly reduced the amount of bleeding during endoscopic sinus surgery and time of the surgery and improved the quality of the surgical field.

Tissue eosinophils and mucous inflammatory cytokines for the evaluation of olfactory recovery after endoscopic sinus surgery in patients with nasal polyposis

Eighty-five patients who underwent endoscopic surgery for nasal polyposis were enrolled in this study. Olfactory measurements were performed before surgery and 3-6months after surgery using a T&T olfactometer. Baseline characteristics of CRSwNP patients were collected, and Spearman's rho correlation was performed to assess the association of olfactory function with tissue eosinophils and mucous inflammatory cytokines. A multivariate logistic regression model was used to assess the independent predictors of olfactory outcomes after surgery. Here, 85 CRSwNP patients, including 25 patients without olfactory disorder and 60 patients with hypo-anosmia, were evaluated. Of the 60 patients with preoperative hypo-anosmia, 22 did not have improved olfactory function, and 38 demonstrated normal olfactory function after surgery based on the T&T olfactometer results. The levels of tissue eosinophil, interleukin-5 (IL-5), IL-13, eotaxin-3, and periostin in the preoperative hypo-anosmia group were higher than those in the preoperative normosmia group. Tissue eosinophil count, IL-5, and periostin levels in patients without olfactory improvement were higher than those in patients with olfactory improvement. The tissue eosinophil count, blood eosinophil count, and nasal mucus levels of IL-5, eotaxin-3, and periostin were significantly correlated with olfactory function in all patients with CRSwNP. The IL-5 level remained a strong predictor of poor olfactory outcomes after surgery. Both tissue eosinophils and mucous inflammatory cytokines, including IL-5, IL-13, eotaxin-3, and periostin, may contribute to the pathogenesis of CRSwNP-associated olfactory dysfunction. Higher IL-5 levels are associated with a lower chance of olfactory function recovery after each surgical revision.

Persistent discharge or edema after endoscopic sinus surgery in patients with chronic rhinosinusitis is associated with a type 1 or 3 endotype.

Patients with chronic rhinosinusitis (CRS) may have persistence of polyps, discharge, or edema after endoscopic sinus surgery (ESS). Inflammation in CRS can be classified into three endotypes, with the presence of polyps associated with the type 2 endotype. Here, we evaluate the endotypic underpinnings of discharge or edema without polyps after ESS. At a visit 6-12 months post ESS, patients underwent endoscopy and completed the CRS-PRO and SNOT-22. Luminex analysis of middle meatal mucus obtained at that visit was performed for IFN-γ, ECP, and IL-17a. Type 1, 2, and 3 endotypes were defined as greater than the 90th percentile expression of each marker, respectively, in controls. Wilcoxon rank-sum and chi-squared tests were used to compare cytokine levels and endotype prevalence between those with and without endoscopic findings. A total of 122 CRS patients completed a clinical exam (median: 8.2 months post ESS). Of the 122 patients, 107 did not have polyps on endoscopy. Of these 107 patients, 48 had discharge, 44 had edema, and 46 had neither discharge nor edema. Compared with those patients without any findings, patients with discharge or edema reported significantly worse severity as measured by CRS-PRO (10.5vs. 7.0, p=0.009; 12.0vs. 7.0, p<0.001; respectively), and had higher post-ESS IFN-γ, ECP, and IL-17a. Patients with discharge had higher prevalence of only T1 and T3 endotypes, while patients with edema had higher prevalence of only the T3 endotype. Post-ESS discharge or edema in the absence of polyps was associated with higher patient-reported outcome severity and was more strongly associated with type 1 or 3 inflammation.
