Gender differences in outcomes following endoscopic sinus surgery: a systematic review and meta-analysis.

The extent to which gender affects outcomes in chronic rhinosinusitis (CRS) is unclear. The objective of this study was to examine differential outcomes between genders following endoscopic sinus surgery (ESS) among CRS patients. PubMed/Ovid, Embase and Cochrane databases were queried. Outcomes included disease burden on imaging and endoscopy, patient-reported outcome measures (PROMs) including the Sinonasal Outcome Test (SNOT-22), revision rates, and olfactory outcomes. Meta-analysis was performed using the Mantel-Haenszel method with random effects model. Of 4,656 articles screened, 32 (n=103,499) were included for qualitative analysis and four (n=2,602) for meta-analysis. On qualitative analysis, 19 of the 32 studies noted a significant gender difference in post-operative outcomes, with five studies favoring women and 14 favoring men. Nine of 18 studies with PROMs noted a difference between genders, all favoring men. Olfactory outcomes were mixed with studies divided on favoring men vs women. No studies noted significant gender differences of disease burden on imaging or endoscopy. Across four studies included in the meta-analysis, women had higher preoperative and post-operative SNOT-22 scores. Meta-analysis shows that women patients have worse pre and postoperative SNOT-22 scores. Postoperative gender differences are most apparent in studies that examined PROMs. Further research is needed to investigate the underlying causes and to mitigate disparities between genders.

Comparison of patient-reported outcomes and clinical characteristics among patients with pituitary macroadenomas and giant adenomas.

Patients with giant adenomas are more likely to have tumor extension into the paranasal sinuses. Compared to macroadenomas, giant adenomas are not associated with worse preoperative SNOT-22 scores.

Comparison of Long-Term Postoperative Outcomes of the Subtypes of Chronic Rhinosinusitis with Nasal Polyps.

(1) Background: Chronic rhinosinusitis with nasal polyps (CRSwNP) is a chronic inflammatory condition that significantly impacts the health-related quality of life (HRQOL) of patients. This study aims to investigate the disparities in preoperative examination findings, postoperative HRQOL, and disease control status based on CRSwNP subtypes. (2) Methods: A retrospective analysis was conducted on 202 patients who underwent endoscopic sinus surgery for CRSwNP. The study assessed clinical characteristics, blood eosinophil and immunoglobulin E (IgE) levels, modified Lund-Kennedy and Lund-Mackay scores, and Japanese Epidemiological Survey of Refractory Eosinophilic Chronic Rhinosinusitis (JESREC) scores. HRQOL was evaluated using the Sino-nasal Outcome Test (SNOT-22) scores, and disease control status was assessed based on the European Position Paper on Rhinosinusitis and Nasal Polyps 2020 guidelines. (3) Results: Of the 202 patients, Eosinophilic CRSwNP patients exhibited significantly higher preoperative peripheral blood eosinophil ratios and IgE levels, and JESREC scores (p < 0.05). Two years postoperatively, patients in the non-eosinophilic group showed significantly improved SNOT-22 scores compared to preoperative scores (p = 0.007). Notably, the proportion of patients with uncontrolled disease was significantly higher in the eosinophilic group (p = 0.035). Logistic regression analyses identified preoperative SNOT-22 scores and eosinophilic CRSwNP subtype as influential factors on disease control status (p < 0.05). (4) Conclusions: Patients with more severe preoperative symptoms and eosinophilic CRSwNP demonstrated poorer long-term treatment outcomes.

Is the relationship between SNOT-22 and NOSE and mucociliary clearance time an appropriate assessment method for functional outcomes of septorhinoplasty?

Objectives: The study aimed to evaluate subjective and objective results after septorhinoplasty and to investigate the correlations between NOSE and SNOT-22 scales and saccharin clearance test (SCT) results. Patients and Methods: One hundred patients (37 males, 63 females; mean age: 26.4±8.4 years; range, 18 to 56 years) with nasal septal surgery indication were included in the study between January 2017 and January 2019. A SCT was applied to all cases preoperatively and in the first postoperative month, and SNOT-22 and NOSE questionnaires were filled. Results: No relationship was detected when the relationship between preoperative SCT and NOSE and SNOT-22 scores was evaluated. However, there was a statistically significant correlation between preoperative SNOT-22 scores and postoperative SCT values in 26% of the cases (r=0.260). Similarly, if the preoperative NOSE and SNOT-22 scores of the cases are low, it should be expected that the SCT value measured at the first postoperative month will be low, with a probability of 28% and 26%, respectively. As the preoperative NOSE value of the patients increased, the SNOT-22 value increased by 57.9% and 27.6%, respectively. Similarly, as the postoperative NOSE values increased, the postoperative SNOT-22 values increased by 51.8%. A positive relationship was found in all these bilateral correlations. According to the results obtained, the NOSE and SNOT-22 scores were 93% accurate and 98% acceptable. Conclusion: Although the statistically significant relationship between SCT results in the postoperative period and SNOT-22 and NOSE is a remarkable finding, there is a need for future studies that also evaluate long-term results to make more precise comments on this issue.

Postoperative mometasone irrigations improve quality of life in skull base tumor patients.

The use of topical corticosteroids to manage postoperative sinonasal symptoms after endoscopic skull base surgery (ESBS) has not been well studied. We quantified long-term impact of postoperative steroid irrigations (SIs) on quality of life of patients after ESBS. Retrospective review of patients at the University of Pennsylvania undergoing ESBS from 2010 to 2019. Data on patient demographics and postoperative treatment with nasal saline irrigation twice daily with and without dissolved steroids (mometasone or budesonide) was collected. Preoperative, and 1-, 3-, 6-, 12-, 18-, and 24-month postoperative Sino-Nasal Outcome Test (SNOT-22) scores were assessed. A total of 727 patients were assessed (53.4% males), with 479 patients in the no SI group and 248 patients in the SI group. Preoperative SNOT-22 scores did not differ significantly (P = 0.19). 1-, 3-, 6-, 12-, 18-, and 24-month post-op SNOT-22 scores did not significantly differ between groups. However, mometasone irrigations resulted in significantly lower postoperative 2-year SNOT-22 scores compared to budesonide (P < 0.01) and saline (P = 0.03). Though corticosteroid irrigations are routine in managing inflammatory sinus disease, their role in postoperative management after ESBS for tumors is unclear. Our findings suggest that mometasone irrigation may be effective at improving postoperative quality of life in patients after ESBS.

Revision Rates and Symptom Trends Following Endoscopic Sinus Surgery: Impact of Race on Outcomes.

The purpose of this study is to determine the impact of demographics and sinonasal comorbidities on the revision rate of functional endoscopic sinus surgery (FESS) for chronic rhinosinusitis (CRS). Although endoscopic sinus surgery (ESS) is often successful in providing long-term relief for patients suffering from CRS, revision surgery can occur. There is conflicting literature on the impact of race on FESS outcomes. A single-center retrospective cohort study of patients that underwent FESS for CRS between January 1, 2015 and June 1, 2021 at a single tertiary care academic center. A total of 682 patients between the ages of 18 and 89 underwent primary ESS between January 1, 2015 and June 1, 2021 and were included in this study. Of these patients, 388 (56.9%) were female, with an average age of 48.6 ± 16.7. Thirty-eight patients (5.6%) underwent revision sinus surgery during the study period. Patients that identified as White had significantly lower rates of revision sinus surgery (4.1%) than non-White patients (10.7%), including those identifying as Asian, Black, multiracial, or other. On multivariate analysis, non-White race (OR 4.933), polyposis (3.175), and high preoperative SNOT-22 scores (OR 1.029) were independently associated with revision sinus surgery. The mean preoperative SNOT-22 for all participants was 39.1 ± 22.0, whereas the mean postoperative SNOT-22 was 20.6 ± 17.5 (p < 0.001). Race plays an important role in outcomes following revision sinus surgery that is independent of location and insurance status. More studies are required to assess the reason race plays an important role in outcomes following revision sinus surgery. Level 3 Laryngoscope, 133:2878-2884, 2023.

Histopathologic Features of Chronic Rhinosinusitis in Diabetic Patients.

To explore how diabetes mellitus impacts chronic rhinosinusitis clinically and on structured histopathology to provide insights on new potential chronic rhinosinusitis endotypes. Retrospective cohort study. Tertiary academic center. A retrospective study of chronic rhinosinusitis patients who underwent functional endoscopic sinus surgery from 2015 to 2020 was performed. Structured 13-variable histopathology reports were generated from intraoperative sinonasal specimens. These variables were compared against demographic factors, comorbidities, culture data, and preoperative Lund-Mackay and SNOT-22 scores using logistic regression. There were 411 patients, including 52 diabetics. Diabetes was associated with higher mean body mass index(34.9 vs29.2; p < .001), age (57.8 vs 48.0; p < .001), and Gram-negative (40.2% vs 22.7%; p < .030) and coagulase-negative Staphylococcus (49.0% vs 28.5%; p = .008) culture rates. Black (23.1% vs 18.7%) and Hispanic (23.1% vs 8.6%) races were more common with diabetes (p = .026). Gender, smoking, polyp status, and Lund-Mackay and SNOT-22 scores did not differ between groups. Diabetics had more fungal elements (13.5% vs 3.3%, p = .018); no other histopathological differences were seen. When controlling for demographic variables and comorbidities, diabetes independently predicted the presence of fungal elements (HR 4.38, p = .018). Diabetic chronic rhinosinusitis patients demonstrated increased fungal elements on structured histopathology. Other histopathological features were unaffected by diabetes. These findings may have important implications on the medical and surgical management of diabetic chronic rhinosinusitis patients in which early fungal disease assessment is paramount.

The role of TAS2R38 genotype in surgical outcomes and culturable bacteria in chronic rhinosinusitis with or without nasal polyps.

Recent studies reported the relationship between genetic variations and TAS2R38, which is a bitter taste receptor expressed in the cilia of human sinonasal epithelial cells, among the predisposing factors playing role in immune response to upper respiratory tract bacterial infection. The present study aims to examine the relationship of TAS2R38 genotype with the active microorganism and the effect of genotype on the surgical outcomes among chronic rhinosinusitis patients. 34 patients undergoing endoscopic sinus surgery (ESS) for chronic rhinosinusitis with or without polyps (23 CRSwNP, 11 CRSsNP) and 30 patients undergoing septoplasty surgery for isolated nasal septum deviation were included. All the patients were genotyped for TAS2R38. Scoring was made using endoscopic Modified Lund-Kennedy and radiological Lund-Mackay systems preoperatively. Sino-Nasal Outcome Test with 22 items (SNOT-22) was implemented preoperatively and postoperatively. Nasal swab culture samples were taken intraoperatively from CRS patients and the active microorganism were isolated. In the TAS2R38 genotyping of the study group, PAV/PAV was found in 32.4% of patients, PAV/AVI in 47.1%, and AVI/AVI in 20.6%. In the control group, PAV/PAV was found in 26.7%, PAV/AVI in 36.7%, and AVI/AVI in 36.7%. In the study group, there was no statistically significant difference between the CRS and CRS subgroups in terms of TAS2R38 genotype distributions. The changes in patients' preoperative and postoperative SNOT-22 scores were similar between the genotypes. Proliferation was detected in culture in the whole AVI-AVI group, 81.8% of PAV-PAV group, and 56.3% of PAV-AVI group but the difference was not found to be statistically significant. The proliferation level of Staphylococcus epidermidis by TAS2R38 genotype was found to be statistically significantly higher among patients, who had AVI-AVI genotype, in CRSwNP. We did not find a statistically significant relationship between the TAS2R38 genotype and CRS subtype, sinonasal bacterial infection risk increase and surgical success rate in CRS patients. Long-term and large-scale studies are needed, which are to be carried out by individual genotyping and sequencing to provide more information on the effects of these genetic variants.

Clinical outcomes of Eustachian tube dysfunction in chronic rhinosinusitis following endoscopic sinus surgery.

The effects of endoscopic sinus surgery (ESS) on the symptom burden of Eustachian tube dysfunction (ETD) in chronic rhinosinusitis (CRS) patients were investigated. Ninety-two patients with CRS following ESS were prospectively enrolled and followed up every 3 months for 1 year. The 7-item ETD Questionnaire (ETDQ-7) and 22-item Sino-Nasal Outcome Test (SNOT-22) were administered before ESS and at each visit following ESS. Before surgery, 25% of patients reported ETDQ-7 scores ≥ 14.5, indicating the presence of ETD. The mean preoperative ETDQ-7 and SNOT-22 scores were 13.3 and 40.0, respectively. The mean ETDQ-7 and SNOT-22 scores were significantly decreased to 8.2 and 17.0 at 1 year following ESS, respectively. Most patients reported alleviation of their symptoms within the first 3 months, and the prevalence of ETD had decreased to 3.3% at 1 year. Patients who received revision surgery had higher ETDQ-7 scores during the follow-up period. Additionally, 5.4% of patients reported worsening of their symptoms. ETD symptoms can be effectively alleviated in most patients within 3 months following ESS. However, 5.4% of patients reported worsening of their symptoms at the 1-year follow-up. Additional objective studies should be conducted to evaluate Eustachian tube function thoroughly in CRS patients.

Improving predictability of IgE-high type 2 chronic sinusitis with nasal polyps in the biologic era

BackgroundChronic rhinosinusitis (CRS) is an inflammatory disease that may require biological therapy. Omalizumab is an anti-IgE biologic that was recently approved by the FDA and Health Canada for use in severe CRS with nasal polyps (CRSwNP) recalcitrant to intranasal corticosteroids. Dosing is based on weight and pre-treatment serum IgE, with elevated levels of the latter being an indication for biologic treatment according to EPOS and EUFOREA guidelines. The goal of this study was to identify variables that predict IgE-high type 2 inflammation and serve as indicators for biologic treatment in CRS.MethodsPatients ≥ 19 yo diagnosed with CRS undergoing functional endoscopic sinus surgery were included retrospectively. Demographics, past medical history, preoperative blood work, Lund-Mackay (LM), Lund Kennedy (LK), and SNOT-22 scores were extracted. Descriptive statistics and binary logistic regression analyses were conducted. Model superiority was based on Nagelkerke R2 scores and receiver operating characteristic curves.ResultsSixty-five patients, average age 49.96 ± 13.59 years, were included. Sixty-one binary logistic regression models for elevated serum IgE were created. Among the top 3 models, the best model had sensitivity, specificity, positive predictive value and negative predictive values of 82.1, 69.2, 80.0, and 72.0. All performance measures except sensitivity exceeded the Canadian Biologics Guideline model. Serum eosinophils ≥ 300 cell/uL, CRSwNP and LM ≥ 17 increased the odds of elevated IgE.ConclusionsIgE-high type-2 inflammation can be predicted by a model that includes eosinophil ≥ 300 cell/uL, CRSwNP, LM ≥ 17, asthma diagnosis and SNOT-22 ≥ 40. Patients meeting these parameters have a high pretest probability for elevated IgE and would benefit from IgE serology to determine qualification for omalizumab. This could reduce unwarranted IgE serology in patients with CRSwNP but also target a patient population for further workup that will lead to optimization of resource allocation and improve healthcare equity in rural and remote areas within Canada.

Association of gastro-oesophageal reflux disease and quality of life in patients with chronic rhinosinusitis.

SUMMARYObjectiveWe determined the influence of gastro-oesophageal reflux disease (GERD) on quality of life (QOL) before and after functional-endoscopic-sinus-surgery (FESS) for chronic rhinosinusitis (CRS).MethodsMedically-recalcitrant CRS patients were recruited prior to FESS. GERD was diagnosed endoscopically. QOL was compared between patients with vs without GERD at baseline and one-year post-FESS.ResultsOf 187 CRS patients receiving FESS, 40 had GERD. Pre-operative QOL was significantly worse in CRS patients with vs without GERD. Pre-operative GERD health-related QOL (GERD-HRQL) and reflux symptom index (RSI) scores were both correlated with pre-operative SNOT-22 scores. Compared with non-GERD CRS patients, GERD patients demonstrated larger SNOT-22 improvements after FESS, such that post-operative SNOT-22 values were no longer significantly different between GERD and non-GERD groups. However, post-FESS, in patients with CRS without nasal polyps (unlike those with nasal polyps), the GERD (vs non-GERD) group suffered from greater sleep dysfunction and otologic/facial symptoms.ConclusionsCompared to CRS patients without GERD, those with GERD experienced poorer pre-operative QOL and greater QOL improvement after FESS.

Defining the Allergic Endotype of Chronic Rhinosinusitis by Structured Histopathology and Clinical Variables

Atopy has a strong association with chronic rhinosinusitis (CRS). To understand whether patients with atopy and CRS can be defined by markers of tissue histopathology, systemic biomarkers, and clinical factors, which may guide their response to new pharmacologic agents. In a retrospective cohort of CRS patients who underwent functional endoscopic sinus surgery, a structured histopathology report consisting of 12 variables, comorbid conditions, preoperative total serum IgE levels, and preoperative modified Lund-Kennedy endoscopic and sinonasal outcome test (SNOT-22) scores were compared between atopic CRS (aCRS) and non-aCRS control patients in a multivariable model. A total of 380 CRS patients were enrolled, 286 of whom had comorbid atopy (aCRS). Compared with non-aCRS, aCRS patients had significantly higher preoperative total SNOT-22 scores (40.45 ± 22.68 vs 29.70 ± 20.68, P= .015) and symptom-specific SNOT-22 scores in all domains except psychological dysfunction. Relative to non-aCRS, aCRS patients had increased tissue eosinophilia (P < .0001), eosinophil aggregates (P < .0001), Charcot-Leyden crystals (P < .04), fibrosis (P < .02), total serum IgE levels (P < .04), polyploid disease (P < .001), and a prevalence of comorbid asthma (P<.0001) and aspirin exacerbated respiratory disease (AERD) (P < .003). Patients with aCRS demonstrated increased tissue eosinophilia compared with non-aCRS patients even after controlling for polypoid disease, asthma, and AERD. In the context of CRS, atopy appears to be a specific predictor of CRS severity linked to specific histopathologic variables, including enhanced eosinophilic aggregates. Moving forward, allergic status may be a useful way to identify an atopic endotype of CRS patients. Furthermore, after surgery, patients are often maintained on intranasal corticosteroids. In patients whose disease is unresponsive to steroids, we may look to atopic status to identify another management therapy. Atopic CRS patients, irrespective of polypand asthmatic status, could be optimal candidatesforbiologicagents such as T-helper cell, eosinophil, and/or IgE-targeted therapies.

Pre-intervention SNOT-22 scores predict outcomes in aspirin exacerbated respiratory disease

PurposeThis study evaluated whether stratified preoperative, pre- aspirin desensitization (AD) sinonasal symptom scores predict postoperative, post-AD outcomes in Aspirin exacerbated respiratory disease (AERD). Materials and methodsRetrospective chart review of patients with aspirin challenge-proven AERD who underwent endoscopic sinus surgery followed by AD was performed. Preoperative, postoperative/pre-AD, and postoperative/post-AD sinonasal symptom scores were collected (22-item Sino-Nasal Outcomes Test, SNOT-22). A longitudinal linear mixed-effects model was used for data analysis. ResultsForty-seven patients (59.6% female) aged 48.0 ± 13.2 were included. Average time from surgery to AD was 70.0 ± 52.8 days. Preoperative SNOT-22 scores (n = 47) were divided into tertiles (cutoffs of 36 and 54 indicating mild [22.5 ± 13.7], moderate [44.3 ± 12.2], and severe [72.9 ± 19.7] disease). This corresponded to 12 (25.5%), 18 (38.3%), and 17 (36.2%) subjects being categorized into mild, moderate, and severe tertiles, respectively. Postoperative, pre-AD SNOT-22 in all disease groups decreased and were not significantly different (12.3 ± 13.7, 11.1 ± 12.2, 22.7 ± 19.7; p = 0.074). At short-term post-AD, only the severe group worsened (35.0 ± 20.3, p < 0.001), whereas other groups demonstrated negligible change (9.3 ± 14.3 and 14.4 ± 12.2). At long-term post-AD, all groups redemonstrated convergence in symptom scores (23.7 ± 20.9, 19.4 ± 15.4, and 31.0 ± 27.6, p = 0.304). ConclusionPreoperative SNOT-22 scores may be used as a predictor of postoperative, post-AD patient-reported outcomes in AERD. Patients with mild and moderate disease may derive benefit from surgery and AD alone, while those with severe disease may require additional interventions (e.g., biologics).

Geriatric Sinus Surgery: A Review of Demographic Variables, Surgical Success and Complications in Elderly Surgical Patients.

ObjectiveDemonstrate feasibility, safety and outcome metrics of geriatric sinus surgery (GESS).Study DesignRetrospective review of patients undergoing sinus surgery for indication of chronic rhinosinusitis with and without nasal polyposis.SettingTertiary referral center.ParticipantsPatients who underwent FESS from 2008–2017; excluding skull base, craniofacial, or oncologic surgery. Primary study group were patients aged 65 years and older. Patients aged 40–64 years of age were included for comparison.Main Outcomes and Measures: Multivariate analysis was performed to identify independently associated patient characteristics and perioperative variables. Preoperative medical and treatment history, revision and primary surgery, preoperative and post-operative SNOT-22 and NOSE scores, Lund-McKay scores were recorded when available. Post-operative data was assessed at a minimum of two months after the index procedure. Post-operative complications were included.ResultsNinety-one (91) patients met criteria. 21.2% of the geriatric patients were taking systemic anticoagulation prior to surgery, and underwent treatment with nasal steroids (25.0%), oral antibiotics (67.7%), nasal irrigations (48.4%), and systemic steroids (37.5%) over an average of 7.3 months prior to surgery. There was an average post-operative reduction of 15.0 points (p < 0.0001) and 42.5 points (p = 0.0008) for SNOT-22 and NOSE scores, respectively. Average operative time was 117.4 minutes in geriatric patients compared to 183.4 minutes in younger patients (p = 0.004), with an average estimated blood loss of 55.6 milliliters (mL) compared to younger patients (111.8 mL) (p = 0.04). Linear regression identified revision surgery as associated with reductions in Sinonasal Outcome Test (SNOT-22) scores (p = 0.011). Geriatric patients had a shorter operative time (p = 0.011) while male sex was associated with a longer operative time (p = 0.014). Patients over 65 had fewer minor complications (p = 0.01), and there were no major complications in either group.Conclusions and RelevanceGeriatric sinus surgery is effective and safe in this cohort of patients.

The surgical management of recurrent acute and chronic barosinusitis in sports self-contained underwater breathing apparatus (scuba) divers

The aim of this retrospective study is to evaluate the feasibility of functional endoscopic sinus surgery (FESS) with supplementary surgical procedures in scuba divers with recurrent acute barosinusitis (RABS) and chronic barosinusitis (CBS). In this retrospective study, 25 divers were classified into RABS (n:11) and CBS (n:14) groups. The presentation of divers have been reviewed. The PNS CT images were scored according to Lund-Mackay (L-M) system. A score has been assigned to the extent of endoscopic procedures performed. The outcome of surgery and life quality were determined by SNOT-22 and dive-related questions (DRQ) tests. The average L-M score was 3.8 ± 2 for RABS and 12.2 ± 3.4 for CBS groups. L-M score of CBS group was found to be statistically higher than RBS group (p < 0.05). The FESS score of CBS group (8.7 ± 2.4) was higher than RABS group (5.6 ± 2) which showed that the endoscopic sinus procedures were performed more extensively in CBS group (p < 0.05). The difference between the preoperative and postoperative SNOT-22 scores indicates that the degree of sinus symptoms improved better in RABS group than CBS group (p < 0.05). When DRQ test was evaluated, RABS group showed a better improvement in diving performance symptoms than the CBS group (p < 0.05). Our study demonstrated that divers with RABS and CBS can be managed successfully with FESS and supplementary surgical procedures. The improvement in the RABS group was superior to the CBS group, a difference attributed to the severity of chronic inflammation in CBS.

Indications and Outcomes for Patients With Limited Symptoms Undergoing Endoscopic Sinus Surgery.

Previous research have suggested that chronic rhinosinusitis (CRS) patients with lower symptomatic scores, demonstrated by a 22-item Sinonasal Outcome Test (SNOT-22) score <20, may not achieve meaningful quality of life improvement following endoscopic sinus surgery (ESS). However, indications for ESS are continuing to be defined and many low SNOT-22 scoring patients still undergo elective surgery for CRS and other benign sinonasal pathologies. The outcomes for these patients have not been previously studied. We sought to evaluate surgical indications and outcomes for those patients with limited symptoms undergoing ESS. We screened 2829 ESS procedures from 2010-2018 to identify patients with a preoperative SNOT-22 score <20. We reviewed disease characteristics, preoperative Lund-Mackay (LM) scores, and pre- and postoperative SNOT-22 scores in patients with at least 3 months' follow-up. Of all surgical ESS patients screened, 114 had low preoperative SNOT-22 scores (4.0%). Indications for these surgeries included CRS (50.0%), odontogenic sinus disease (11.4%), mucocele (10.5%), recurrent acute sinusitis (7.0%), fungal ball (5.3%), and silent sinus syndrome (4.4%). Specifically, among CRS patients, 45.6% had pulmonary comorbidities and/or systemic immunodeficiencies. Moreover, 100% of CRS patients with nasal polyps and 73.1% of CRS without polyps had LM scores >5. Patients with preoperative SNOT-22 scores between 15 and 19 achieved an average 6.5 point reduction (P < .001) postoperatively, whereas those with scores between 10 and 14 had a 5.4 point reduction (P < .001), and preoperative scores <9 resulted in no significant decrease in postoperative symptom scores (P = .98). Overall, there was a 3.3 point SNOT-22 reduction among all patients at 3 months postoperatively (P < .001). Patients with limited sinonasal symptoms may benefit from surgical treatment despite asymptomatic clinical presentations. A case-by-case analysis of comorbidities or unique clinical features should inform surgical decision-making for patients with lower SNOT-22 scores.

Correlation between extent of sinus surgery, radiographic disease, and postoperative outcomes.

The extent of endoscopic sinus surgery (ESS) required for optimal outcomes in chronic rhinosinusitis (CRS) is undefined. We evaluated whether concordance between the extent of surgery and degree of radiographic disease influences postoperative outcomes. 247 CRS patients who underwent ESS were retrospectively assigned a concordance score reflecting the similarity between the extent of surgery and degree of radiographic disease. 0 points were assigned when sinusotomy was performed on a diseased sinus, or no sinusotomy was performed on a nondiseased sinus; plus 1 for sinusotomy on a nondiseased sinus; and -1 for a diseased sinus left unopened. The total possible score ranged from minus 10 to plus 10. Patients were divided into 5 subgroups according to variance from complete concordance. SNOT-22 scores and revision rates were compared at 6 and 24 months. All five subgroups had similar preoperative SNOT-22 scores and improved at 6 months postoperatively. At 6 months postoperatively, the most conservatively operated and most extensively operated subgroups each achieved equivalent improvements in SNOT-22 as the completely concordant subgroup. At 24 months, the most extensively operated subgroup had a 12.5-point smaller improvement in SNOT-22 scores compared to the completely concordant subgroup. Multivariate analysis showed no association between concordance score and revision rate. Symptom improvement and revision rates after ESS do not appear to correlate with the degree of concordance between extent of surgery and radiographic disease. More extensive surgery than indicated by CT confers neither greater symptomatic improvement nor long-term detriment.

Sinonasal quality-of-life outcomes after endoscopic endonasal skull base surgery.

There are substantial gaps in our understanding of the influence of the endoscopic endonasal approach (EEA) for endoscopic skull base surgery on sinonasal-specific quality of life (QOL) as well as the instruments available for assessment. Our primary objective in this study was to characterize postoperative changes in sinonasal QOL, specifically using the 22-item Sino-Nasal Outcome Test (SNOT-22), with a secondary objective of delineating weaknesses in our current understanding of patient symptomatology after EEA for skull base surgery. A comprehensive literature review was conducted using PubMed, CINAHL, Cochrane Library, and SCOPUS for studies reporting SNOT-22 data pre- and postoperatively in patients who underwent EEA for skull base pathologies. Studies were limited to patients ≥18 years of age and excluded patients diagnosed with chronic rhinosinusitis (CRS). Nineteen unique studies with 27 separate data sets and a total of 1025 patients were used in this meta-analysis. Overall SNOT-22 scores statistically improved at the 6-month (p = 0.0009) and 1-year (p = 0.002) time-points. Patients with preoperative SNOT-22 scores ≥20 achieved postoperative improvements at 12-week (p < 0.00001), 6-month (p < 0.0001), 1-year (p < 0.00001), and long-term follow-up (p < 0.0001). Patients with preoperative SNOT-22 scores <20 remained stable and did not worsen postoperatively. Patients undergoing EEA for skull base pathologies who have impaired sinonasal QOL preoperatively demonstrated significant postoperative QOL improvements. Those patients with relatively normal preoperative sinonasal QOL remained asymptomatic postoperatively. This study supports the need for development of a contemporary disease- and approach-specific, validated QOL instrument for skull base pathologies.

Improved perioperative quality of life in endoscopic sinus surgery by application of enhanced recovery after surgery.

Background: Endoscopic sinus surgery (ESS) has been the definitive treatment for chronic rhinosinusitis (CRS), but the complications caused perioperatively may affect patients’ quality of life (QoL). This study aims to evaluate the effects of enhanced recovery after surgery (ERAS) on improving perioperative QoL in ESS.Materials and methods: Seventy-four patients with chronic rhinosinusitis with nasal polyps (CRSwNP) met the criteria for inclusion. Participants undergoing ESS were randomly divided into an ERAS group and a control group, and QoL assessment was performed using the Chinese version of the 22-item Sinonasal Outcomes Test (SNOT-22). Measurements were administered at baseline, and on postoperative day 1 (POD1), POD3 and POD6. Complications such as nausea/emesis, hemorrhage, aspiration and dizziness were also recorded.Results: The preoperative global SNOT-22 scores (mean ± SD) were 39.89±4.86 in the ERAS group and 40.52±3.61 in the control group (t=0.643, P=0.522). On POD1, the global SNOT-22 scores increased significantly to 51.77±5.59 and 62.02±3.86 (t=9.218, P<0.01), and on POD3 they increased to 48.22±6.22 and 51.11±5.14, respectively (t=2.179, P<0.05). However, the scores recovered to 39.39±4.73 and 40.13±3.31 in the respective groups on POD6, which were lower than but not statistically significant different from the baseline (t=0.786, P=0.434). There were statistically significant improvements across all subdomains of SNOT-22 for patients in the two groups only in POD1 (all P<0.05). The ERAS group did not have an increased incidence of complications such as nausea/emesis (χ2=0.223, P>0.05), hemorrhage, aspiration and dizziness compared to the control group.Conclusion: ERAS could improve perioperative QoL in patients with CRSwNP undergoing ESS, and SNOT-22 can be used for ERAS evaluation as a patients’ outcome report.
