Endoscopic sinus surgery for chronic rhinosinusitis: 22-item Sino-Nasal Outcome Test 5-year results

Rheumatoid Arthritis Exacerbates Eosinophilic Inflammation Contributing to Postoperative Recurrence in Chronic Rhinosinusitis with Nasal Polyps

Objective

To assess the impact of rheumatoid arthritis (RA) on histopathological features and the risk of postoperative recurrence in chronic rhinosinusitis with nasal polyps (CRSwNP) patients.

Methods

A retrospective cohort study of CRSwNP patients who underwent functional endoscopic sinus surgery was performed. Patients were followed up for more than two years, and classified into RA and Non-RA groups, recurrent and non-recurrent groups. The influence of RA on histopathological features and the risk of CRSwNP recurrence was explored.

Results

A total of 517 CRSwNP patients were finally recruited, including 78 RA patients. The RA group exhibited a higher recurrence rate, tissue eosinophil counts and percentages compared to the non-RA group (P < 0.05). Tissue eosinophil count and percentage, and the prevalence of allergic rhinitis were significantly higher in the recurrent group in compared to the non-recurrent group (P < 0.05). Multivariate logistic regression analysis identified tissue eosinophil count and percentage, RA, and allergic rhinitis as significant predictors of increased recurrence risk (P < 0.05). Both adjusted and unadjusted models affirmed RA as an independent risk factor for CRSwNP postoperative recurrence (P < 0.05). Kaplan-Meier curves further indicated a higher recurrence risk in CRSwNP patients with RA than those without (P < 0.05).

Conclusion

Our findings suggest that RA significantly exacerbates tissue eosinophilic inflammation and independently heightens the risk of postoperative recurrence in CRSwNP patients. These insights underscore the need for tailored therapeutic strategies addressing the complex interplay between CRSwNP and RA to mitigate recurrence risks and improve clinical outcomes.

Systematic Review of Long Term Sinonasal Outcomes in CRSwNP after Endoscopic Sinus Surgery: A call for Unified and Standardized Criteria and Terms

PURPOSE OF REVIEW

To present current evidence in long-term (> 5 years) results after endoscopic sinus surgery (ESS) focusing on Patients Reported Outcome Measures (PROMs) and other sinonasal outcomes while assessing the role of ESS in the treatment of CRSwNP, and identifying outcomes which affect the results of ESS and defining recommendations for future studies.

RECENT FINDINGS

Long-term results of ESS in CRSwNP can be branched in PROMs and other objective measurements. Despite the heterogeneity of reported outcomes make it difficult to perform comparisons and meta-analysis, ESS improves PROMs, including symptoms, QOL and olfaction. Objectives outcomes such as NPS, LMS, type of surgery, or recurrence and revision surgery don't have a clear role in long-term results. Clustering patients suggest asthma, N-ERD, allergy, eosinophil count and IL-5 could have a role in predicting recurrence and severe disease. Long-term studies of CRSwNP treated with ESS are scarce. There is a significant need to standardize the report of results. The use of tools as SNOT-22, NPS, validated smell tests, defined criteria for disease recurrence and control and ESS extension in a unified systematic way could allow better comparisons between treatments in the new era of biologics.

[Modern management of chronic rhinosinusitis]

Chronic rhinosinusitis is a common disease. Due to the significant reduction of the quality of life, possible serious complications and economic consequences, a sufficient therapy is essential. With the entry of biologics into the treatment of chronic rhinosinusitis, relevant innovations have emerged in recent years. This article is aimed at providing an up-to-date overview of the conservative and surgical treatment options for chronic rhinosinusitis.

Five-year EuroQol 5-Dimension Outcomes After Endoscopic Sinus Surgery

OBJECTIVE

The EuroQol 5-Dimension (EQ-5D) is a general health survey that is quick to administer, widely used, and directly convertible to health utility values (HUV). We aim to describe the five-year EQ-5D outcomes among patients who undergo surgical treatment for chronic rhinosinusitis (CRS).

STUDY DESIGN

Prospective observational cohort study.

METHODS

Patients with CRS completed the EQ-5D questionnaire preoperatively and annually for five years following endoscopic sinus surgery. Paired t-tests and McNemar's tests were used to compare preoperative and postoperative scores. Mixed-effects modeling was used for multivariate analysis.

RESULTS

Among 1296 patients enrolled in our study, 812 (74.7%) completed the postoperative survey at one year and 336 (38.9%) completed it at five years. There was a significant and sustained reduction of patients reporting pain/discomfort (74.9% vs. 58.0%, p < 0.001) and anxiety/depression (49.6% vs. 38.1%, p = 0.01) out to five years. Frequency of problems reported in the usual activity domain decreased at one year and was sustained through year four (30.6% vs 19.7%, p = 0.003). After multivariable modeling, female gender (p = 0.02), prior sinus surgery (p = 0.01), tobacco use (p = 0.038), headaches (p = 0.013), allergies (p = 0.001), diabetes (p = 0.022), hypertension (p = 0.036), higher preoperative SNOT-22 score (p < 0.001), and a lower preoperative Lund-Mackay score (p < 0.001) were associated with significantly worse EQ-5D HUV over time. Similarly, a worse EQ-5D Visual Analog Scale (VAS) over time was associated with allergies (p = 0.03), diabetes (p < 0.001), hypertension (p = 0.04), higher preoperative SNOT-22 score (p < 0.001), and prior sinus surgery (p < 0.001).

CONCLUSION

Patients with chronic rhinosinusitis experience significant sustained improvements in health-related quality of life up to five years after ESS as measured by the EQ-5D instrument.

Visual and bibliometric analysis of chronic rhinosinusitis and nasal polyps

Background

Chronic rhinosinusitis (CRS) is a heterogeneous disease characterized by persistent sinonasal inflammation and sinus microbiome dysbiosis. Nasal polyps (NPs) are one of the main manifestations that cause diverse clinical symptoms of CRS.

Objective

We sought to conduct a bibliometric and visual analysis of articles on CRS and NPs published between 2003 and 2022 to provide researchers with the current state of research and potential directions.

Methods

We searched relevant articles from 2003 to 2022 in the Web of Science database. VOSviewer and the Bibliometrix R package were used to perform the bibliometric analysis.

Results

A total of 3907 publications were retrieved. The United States made the highest contributions to global research, followed by China. Northwestern University had the most publications. The most published author was C. Bachert, followed by R. P. Schleimer and R. J. Schlosser. The authors with the most co-citations were C. Bachert, W. J. Fokkens, and P. Gevaert. Moreover, the journal with the most publications was the International Forum of Allergy & Rhinology, and the Journal of Allergy and Clinical Immunology was the most cited. "Covid-19," "biologics," and "type 2 inflammation" were the top current research hotspots.

Conclusions

The United States and Northwestern University were the leading country and institution in researching CRS and NPs. C. Bachert was the most influential expert. The International Forum of Allergy & Rhinology and the Journal of Allergy and Clinical Immunology were leading journals. "Covid-19," "biologics," and "type 2 inflammation" were the trending topics.

Nasal Irrigation Improves the Nasal Related Quality of Life in Patients Undergoing Transsphenoidal Resection of Pituitary Adenoma

Background: After transsphenoidal pituitary adenoma resection patients have reduced olfactory function and quality of life. This study aimed to evaluate the effects of nasal irrigation on the nasal related quality of life in patients undergoing transsphenoidal pituitary adenoma resection. Methods: Patients undergoing transsphenoidal resection of pituitary adenomas in a tertiary hospital in China were included. The patients were randomly divided into a control group and nasal irrigation group according to the random sequence generated by the SPSS22.0 software. The 22-item sino-nasal outcome test (SNOT-22) was used to evaluate nasal related quality of life; lower SNOT-22 scores indicate a higher quality of life. The Toyota and Takagi (T&T) olfactometer test was used to evaluate the olfactory function of patients. Results: A total of 82 patients were finally included. The SNOT-22 scores of both groups after surgery were significantly higher than those before surgery (p < .05). The total SNOT-22 score of nasal irrigation group at one month (23.45 ± 3.72 vs. 27.48 ± 4.07) and three months (15.83 ± 2.86 vs. 21.82 ± 3.36) after surgery was lower than that in the control group (p < .05). There was no significant difference in olfactory function between the two groups at one month and three months after surgery (p > .05). The nasal mucosal score in the nasal irrigation group was significantly improved compared with the control group at one month and three months after surgery (p < .05). Conclusion: Nasal irrigation is associated with improved quality of life in patients undergoing transsphenoidal pituitary adenoma resection compared with the control group.

5-Item sino-nasal outcome test and 22-item sino-nasal outcome test relationship with endoscopic and radiologic scores in chronic rhinosinusitis with nasal polyps

BACKGROUND

The 22-item sino-nasal outcome test (SNOT-22) is a frequently used patient-recorded outcome measure in patients with chronic rhinosinusitis with nasal polyps (CRSwNPs). Objective findings of nasal polyps and paranasal sinus inflammation are frequently graded using nasal polyp score (NPS) and Lund-Mackay Score (LMS), respectively.

OBJECTIVE

To evaluate a novel, abbreviated, rhinology-focused, five-domain SNOT-5 questionnaire because we had anecdotally noticed a relative disconnect between SNOT-22 and endoscopy and imaging scores.

METHODS

We performed a retrospective, cross-sectional, single-center review of patients with CRSwNPs who had filled out a SNOT-22, along with post hoc-derived SNOT-5 scores, which were then assessed in relation to NPS and LMS.

RESULTS

A total of 129 patients were included in the analysis. SNOT-5 but not SNOT-22 scores significantly correlated vs either NPS (P < .005) and LMS (P < .001), whereas only SNOT-5 differed significantly when comparing the cohort's lowest and highest tertiles for mean LMS: 11.8 vs 16.8 (95% CI, 1.5-8.4; P < .01) and for mean NPS 12.4 vs 15.6 (95% CI, 0.5-5.9; P < .05).

CONCLUSION

In a retrospective, real-life cohort study of CRSwNP, there was a relative disconnect between the significant association of SNOT-5 but not SNOT-22 in relation to objective endoscopy and imaging measures. We, therefore, propose that further prospective intervention studies are indicated in CRSwNP to evaluate the SNOT-5 score including establishing the minimal clinically important difference.

Association of ethnicity and time to surgery among patients with chronic rhinosinusitis

Objectives

Determine factors associated with delayed endoscopic sinus surgery (ESS) in patients with chronic rhinosinusitis (CRS).

Methods

This is a retrospective cohort study conducted at a tertiary care academic center. Patients were included in the study if they were at least 18 years old and underwent surgery for CRS. Electronic medical records were retrospectively reviewed to collect demographic and clinical data. Patients with CRS secondary to another pathology such as malignancy were excluded. Multiple linear regression was performed to determine factors associated with the number of days between a patient's preoperative consultation and the date of surgery.

Results

A total of 103 patients with a mean age of 46.6 ± 16.8 years were included in the analysis; 51.5% of patients were females, 46.6% identified as White, and 29.1% identified as Hispanic. The majority of patients (67.0%) had preferred provider organization health insurance; 43.7% of patients had nasal polyps, 70.9% had a deviated nasal septum, and the mean preoperative Sinonasal Outcomes Test-22 (SNOT-22) score was 41.0 ± 23.8. The mean time to surgery after the final preoperative visit was 71.7 days ± 65.6 days. Hispanic ethnicity was associated with increased time to surgery (p < .05) when controlling for other variables. No other variables were associated with time to surgery on multivariate analysis.

Conclusion

Hispanic ethnicity may be an independent predictor of increased time to sinus surgery independent of disease severity and other demographic variables.

The Impact of Gender on Long-Term Quality of Life After Sinus Surgery for Chronic Rhinosinusitis

OBJECTIVE

To identify the impact of gender on the clinical outcomes of endoscopic sinus surgery (ESS) through the comparison of quality of life measures in female and male patients who undergo surgical treatment for chronic rhinosinusitis (CRS).

STUDY DESIGN

Prospective observational cohort study.

METHODS

Patients with CRS completed the 22-item Sino-Nasal Outcome Test (SNOT-22) and EuroQol 5-Dimension Survey (EQ-5D) preoperatively and annually for 5 years following ESS. Health utility values (HUV) were calculated from EQ-5D scores. Comparisons of cohort characteristics were performed with chi-square and t-tests. A multivariable linear mixed effects model evaluated changes in SNOT-22 and HUV over time by gender.

RESULTS

Among the 1268 patients (54% female) enrolled, 789 and 343 completed postoperative surveys at one and 5 years, respectively. Preoperatively, females experienced more severe symptoms: mean SNOT-22 score (51.1 ± 20.9 female vs. 44.7 ± 20.0 male, p < 0.001) and HUV (0.80 ± 0.14 female vs. 0.84 ± 0.11 male, p < 0.001). These gender differences were resolved by year one postoperatively (SNOT-22: p = 0.083; HUV: p = 0.465). Two years after surgery, however, females reported more severe symptoms (SNOT-22: 25.6 ± 20.7 female vs. 21.5 ± 17.4 male, p = 0.005; HUV: 0.88 ± 0.12 female vs. 0.90 ± 0.11 male, p = 0.018), a difference that persisted at year five. These gender-related differences remained after adjusting for age, race, ethnicity, nasal polyps, history of prior ESS, and smoking status (p < 0.001). Within-subject improvement was comparable between genders (SNOT-22: p = 0.869; HUV: p = 0.611).

CONCLUSION

Females with CRS reported more severe symptoms both before and 5 years after surgery compared to their male counterparts. Understanding the mechanism behind these gender-related differences is important for optimizing CRS treatment.

A Systematic Review and Meta-analysis of SNOT-22 Outcomes After Sinus Surgery

Background: All stakeholders in the healthcare system have prioritized and will continue to prioritize enhancing care quality. The measurement of sinus-specific quality of life (QOL) is potentially the most commonly used QOL parameter for chronic rhinosinusitis (CRS). Objective: A systematic review and meta-analysis were used in this study to determine the mean change in patients' scores on the 22-item Sino-Nasal Outcome Test (SNOT-22) before and after endoscopic sinus surgery (ESS) for CRS. Methods: PubMed, Google Scholar, and ScienceDirect were searched for articles that compared SNOT-22 scores before and after ESS in adult patients with CRS and were published between January 2000 and March 2023. The mean post-op change, 95% confidence interval (CI), forest plot, and inverse variance weighting were all generated using a random effects model. A mixed-effects meta-regression was used to analyze the effect of patient-specific characteristics across studies. Results: Fifteen prospective patient cohorts published from 2009 to 2023 were included in this meta-analysis. At an average follow-up of 25.5 months, all studies demonstrated a statistically significant difference in mean SNOT-22 scores between baseline and post-op time periods (P < .05), ranging from 5.1 to 55.4. Across all studies, the mean SNOT-22 changed significantly by 26.02 (95% CI: 12.83-38.60). According to a stepwise multivariate analysis, studies with higher mean age and mean pre-op SNOT-22 scores had greater changes in SNOT-22 scores following ESS, whereas trials with longer mean follow-up duration had smaller changes in SNOT-22 scores. Conclusion: Research utilizing the SNOT-22 instrument has demonstrated that endoscopic sinus surgery (ESS) leads to enhanced quality of life (QOL) outcomes. The literature reports that improvement is influenced by the initial SNOT-22 score, the mean age of the patients, and the duration of the follow-up period.

ARIA Care Pathways 2019: Next-Generation Allergic Rhinitis Care and Allergen Immunotherapy in Malaysia

An increase in the prevalence of allergic rhinitis (AR) worldwide presents a significant burden to the health care system. An initiative was started in Europe designated as Allergic Rhinitis and Its Impact on Asthma (ARIA) to develop internationally applicable guidelines by utilising an evidence-based approach to address this crucial issue. The efforts are directed at empowerment of patients for self-management, the use of digital mobile technology to complement and personalise treatment, and establishment of real-life integrated care pathways (ICPs). This guideline includes aspects of patients' and health care providers' management and covers the main areas of treatment for AR. The model provides better real-life health care than the previous traditional models. This review summarises the ARIA next-generation guideline in the context of the Malaysian health care system.

Minimal Radiographic Mucosal Thickness or Opacification Criterion for Sinus-Specific Endoscopic Sinus Surgery for Chronic Rhinosinusitis

OBJECTIVE

Primary chronic rhinosinusitis (CRS) is typically a diffuse process and the extent of endoscopic sinus surgery (ESS) performed for medically recalcitrant CRS is impacted by many factors. However, some third-party payors have implemented policies to authorize coverage for ESS in a sinus-by-sinus manner based on a minimal measurement of millimeters of mucosal thickening or sinus opacification in the corresponding sinus that is being surgically addressed. Our objective was to determine whether such policies are based on scientific evidence that in patients with medically recalcitrant CRS, a minimum measurement of mucosal thickening or sinus opacification is a predictor of CRS in that sinus or improved outcomes after ESS on a sinus-by-sinus basis.

DATA SOURCES

Medline, Embase, Scopus, and Web of Science databases, from inception through May 2022.

REVIEW METHODS

A systematic review was performed. The Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA) guidelines were followed.

RESULTS

We identified 6070 abstracts which were screened and from which 112 studies ultimately underwent a full-text review. From these studies, we found that none investigated (or provided evidence of) whether any minimal degree of radiographic mucosal thickening or sinus opacification predicted CRS or better outcomes after ESS in a sinus-specific manner.

CONCLUSION

We were unable to find evidence supporting a minimum millimeter measurement of mucosal thickening or sinus opacification as predictors of CRS or better post-ESS outcomes in a sinus-specific manner in patients with medically recalcitrant CRS. The extent of ESS for CRS should be determined through personalized medical decision-making that considers all patient-specific factors.

Olfactory Change Pattern After Endoscopic Sinus Surgery in Chronic Rhinosinusitis Patients

Background Chronic rhinosinusitis (CRS) is a chronic inflammation of the sinonasal mucosa that is clinically associated with sinus pressure, nasal congestion, rhinorrhea, and a decreased sense of smell that lasts more than 12 weeks. Endoscopic sinus surgery (ESS) for medically refractory CRS is mainly undergone to improve sinus function and access to topical medicinal treatments. However, olfactory changes after ESS can be unpredictable. Aim The current study aimed to assess olfactory change patterns after endoscopic sinus surgery in patients with chronic rhinosinusitis. Methods A record-based retrospective study was conducted in Aseer Central Hospital (ACH) ear, nose, and throat outpatient (ENT OPD) department and Khamis Mushayt General Hospital from August 15, 2021, to December 15, 2021. Data were collected using pre-structured data extraction sheet to avoid errors. Data extracted and collected included patients' biodemographic data, CRS-associated symptoms, and endoscopic surgery-related data, including duration since surgery, presurgical medications, and duration of surgery. Also, postsurgical complications were extracted, especially olfactory complications. Results A total of 168 patients with chronic rhinosinusitis (CRS) and who had undergone endoscopic sinus surgery in the Aseer region were included. Patient ages ranged from 10 to 61 years, with a mean age of 39.8 ± 12.4 years old. Regarding the associated symptoms and complaints of the study patients, 110 (65.5%) complained of sinusitis, and 86 (51.2%) had allergic RS. The postsurgical complications of patients with CRS who had undergone endoscopic sinus surgery were olfactory dysfunction (OD) in 32 (19%), no complications in 115 (68.55%), and other nonspecific complications, such as headache, drowsiness, nose dryness, and bleeding, in 21 (12.55%). Also, 71 (42.3%) reported that they hardly perceive the fragrance in perfumeries. Conclusion In conclusion, olfactory impairment is a frequent clinical presentation in patients with CRS. In this study, olfactory dysfunction was improved, except among nearly one out of each five patients after ESS. Olfactory dysfunction was more among patients who had undergone recent surgery and those with chronic rhinosinusitis with nasal polyps (CRSwNP). Also, among patients who reported no complications, olfactory function did not return to normal in most patients as they hardly perceive fragrance.
