[PMID: 35174505 DOI: 10.1002/lary.30057] [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: 07/26/2021] [Revised: 12/21/2021] [Accepted: 01/24/2022] [Indexed: 02/02/2023]
Abstract
OBJECTIVE To determine how prolonged operative time (POT) impacts 30-day outcomes in patients undergoing endoscopic sinonasal surgery (ESNS). STUDY DESIGN Retrospective study. METHODS Data from patients who underwent ESNS (nonsinus, sinus, and extended sinus) between 2005 to 2018 were collected from the American College of Surgeons National Surgical Quality Improvement database. Univariate and multivariate analyses were performed to evaluate the effect of POT on postoperative outcomes. RESULTS Among 1,994 ESNS cases, 495 nonsinus procedures, 1,191 sinus procedures, and 308 extended sinus procedures were identified. Median OT was 90 minutes (interquartile range [IQR], 51-165 minutes) for nonsinus procedures, 113 minutes (IQR, 66-189 minutes) for sinus procedures, and 187 minutes (IQR, 137-251 minutes) for extended sinus procedures. Other than older age (P = .008), POT was not significantly associated with baseline demographics and comorbidities for patients undergoing non-sinus procedures. Older age (P < .001), White and Black race (P < .001), ASA physical classifications III or IV (P < .001), and several preoperative comorbidities, including obesity (P = .045), and hypertension (P < .001) were associated with POT for sinus procedures. Older age (P = .030), male sex (P = .010), and lower body mass index (P = .004) were associated with POT for extended sinus procedures. After risk-adjustment, POT was independently associated with prolonged hospital stay (LOS) for all procedure categories, and associated with overall surgical complications and postoperative bleeding for sinus and extended sinus procedures specifically. CONCLUSION POT is independently associated with several adverse outcomes following ESNS, including prolonged LOS, overall surgical complications, and bleeding. Preoperative planning should include optimizing modifiable patient risk factors for POT and identifying surgeon-specific factors to enhance surgical efficiency.

Abstract
Taking a novel approach, this narrative review collates knowledge about nasal polyposis and the biological functions of IgE in several diseases (allergic rhinitis, allergic asthma, nonsteroidal anti-inflammatory drugs-exacerbated respiratory disease, and chronic spontaneous urticaria) to consider which IgE-mediated mechanisms are relevant to nasal polyposis pathology. A type 2 eosinophil-dominated inflammatory signature is typical in nasal polyp tissue of European patients with nasal polyposis, with a shift toward this endotype observed in Asian populations in recent years. Elevated polyclonal IgE is present in the nasal tissue of patients with and without allergy. It is derived from many different B-cell clones and, importantly, is functional (proinflammatory). Staphylococcus aureus enterotoxins are thought to act as superantigens, inducing production of polyclonal IgE via B-cell and T-cell activation, and triggering release of inflammatory mediators. In some patients, exposure to antigens/triggers leads to production of high levels of antigen-specific IgE, which mediates cross-linking of the high-affinity IgE receptor on various cells, causing release of inflammatory mediators. The efficacy of omalizumab confirms IgE as an important inflammatory mediator in nasal polyposis. By blocking IgE, omalizumab targets the T2 inflammation in nasal polyposis, reduces nasal polyp score and improves symptoms.

Abstract
OBJECTIVE Evaluate associations of nasal and sinus and related symptoms, as well as selected health conditions which produce those symptoms, with total lost productive time (LPT) at work in the past 2 weeks. METHODS We used a cross-sectional analysis of 2402 currently working subjects. Self-reported physician diagnoses, condition statuses measured with standardized instruments, and symptom-based factor scores from an exploratory factor analysis were used in survey weighted log-binomial regression. RESULTS Pain and pressure, nasal blockage and discharge, and asthma and constitutional symptom factor scores as well as self-reported allergic rhinitis were associated with higher total LPT. Individuals who met operationalized criteria for multiple health conditions, especially chronic rhinosinusitis, had the greatest total LPT. CONCLUSIONS Better management of these symptoms, and awareness of how they impact an individual's ability to perform job-functions in the workplace, could improve overall productivity.

Abstract
BACKGROUND Chronic rhinosinusitis (CRS) is one of the commonest chronic health problems among adults in the UK. Around 15% of CRS patients undergo functional endoscopic sinus surgery (FESS) annually after failing medical treatment. However, as incomplete resolution of symptoms or complications post-operatively is common, the post-operative management is considered to be as important as the surgery itself. A bioabsorbable corticosteroid-eluting sinus implant (CESI) (Propel®, mometasone furoate 370 µg) has been used as an alternative post-FESS treatment. OBJECTIVE The objective of this study was to assess the cost effectiveness of the corticosteroid-eluting implant versus non-corticosteroid-eluting spacer following FESS for treatment of patients with CRS. METHODS A decision tree model was developed to estimate the cost and effectiveness in each strategy. Costs and effects were estimated from a UK National Health Service (NHS) and personal social services perspective over a 6-month time horizon. Model pathways and parameters were informed by existing clinical guidelines and literature and sensitivity analyses were conducted to explore uncertainties in base-case assumptions. RESULTS Over a 6-month time horizon, inserting CESI at the end of FESS is less costly (£4646 vs. £4655 per patient) and is the more effective intervention [total quality-adjusted life-years (QALYs) over 6 months 0.443 vs. 0.444] than non-corticosteroid-eluting spacers; hence, it is a dominant strategy. The probabilistic analysis results indicate that CESI following FESS has a 62% probability of being cost effective at the £20,000/per QALY willingness-to-pay threshold and 56% probability of being a cost-saving intervention. CONCLUSIONS The use of CESI after FESS results in fewer post-operative complications than non-corticosteroid-eluting implants and may be a cost-saving technology over a 6-month time horizon. Although the cost of initial treatment with the CESI is greater, cost savings are made due to a reduction in the number of complications experienced.

Abstract
Objective: This study comprised a long-term follow-up of a cohort of patients with chronic rhinosinusitis (CRS) regarding clinical features and symptomatology. Methods: Data from 42 patients with CRS were available from a previous study. Forty of these patients were alive and were contacted for inclusion after approximately 10 years. Patients completed a questionnaire about disease and symptoms, and underwent a clinical examination. Results: Thirty-four patients (85%) responded and could be included and evaluated. For the participants in this follow-up study median length of time between initial inclusion (C1) and follow-up (C2) was 11 years (range: 8-15). In some patients the CRS shifted phenotype over time, from CRS with nasal polyposis to CRS without nasal polyposis or vice versa. The median total visual analogue score for combined sinonasal symptoms for all patients was statistically significantly reduced at follow-up. For individual patients, scores for nasal congestion, nasal discharge, facial pressure, and hyposmia were also statistically significantly reduced. The most frequently reported symptom-relieving treatments were nasal steroids and saline rinsing of the nose. Self-reported general quality of life was statistically significantly improved at C2 compared to C1. Conclusion: At long-term follow-up, symptoms were generally reduced and patients reported an improved quality of life. Patients can be given hope for eventual symptom relief. CRS is a chronic condition that seems to harbor the ability to alter its phenotype after several years. Topical corticosteroids and saline rinsing of the nose should be emphasized, since patients consider these treatments to be of high value.

Abstract
Perioperative analgesic management is multifaceted, and an individualized approach should be taken with each patient. Preoperative discussion of the plan for pain control and the patient's postoperative expectations is a necessary facet for optimal outcomes of analgesia. There is the potential for significant abuse and development of dependence on opioids. Nonopioids, such as nonsteroidal anti-inflammatory drugs, acetaminophen, and gabapentinoids, provide reliable alternatives for analgesic management following sinus and skull-base surgery. There is a paucity of literature regarding perioperative pain regimens for sinus and skull-base surgery, and the authors hope that this review serves as a valuable tool for otolaryngologists.

Abstract
Objectives Chronic rhinosinusitis (CRS) frequently stems from a dental origin, although odontogenic sinusitis (OS) remains underdiagnosed amongst different professionals. This study aimed to explore how often odontogenic causes are considered when diagnosing CRS. Materials and methods Patient records from 374 new CRS patients treated at a tertiary-level ear, nose, and throat (ENT) clinic were selected. Entries and radiological reports were assessed exploring how often dentition was mentioned and OS was suspected, how often radiologists reported maxillary teeth, and how commonly typical OS microbial findings and unilateral symptoms occurred. Results Although 10.1% of the CRS diagnoses were connected to possible dental issues, teeth were not mentioned for 73.8% of patients. Radiological reports were available from 267 computed or cone beam computed tomographies, of which 25.1% did not mention the maxillary teeth. The reported maxillary teeth pathology was not considered in 31/64 (48.4%) cases. Unilateral symptoms associated with apical periodontitis (OR = 2.49, 95% CI 1.27–4.89, p = 0.008). Microbial samples were available from 88 patients, for whom Staphylococcus aureus was the most common finding (17% of samples). Conclusions Odontogenic causes are often overlooked when diagnosing CRS. To provide adequate treatment, routine assessment of patient’s dental history and status, careful radiograph evaluation, and utilization of microbial findings should be performed. Close cooperation with dentists is mandatory. Clinical relevance Dental professionals should be aware of difficulties medical professionals encounter when diagnosing possible OS. Thus, sufficient knowledge of OS pathology is essential to both medical and dental professionals.

Abstract
PURPOSE OF REVIEW Chronic rhinosinusitis (CRS) has a significant negative impact on quality of life (QoL). Surgical treatment of CRS is indicated when medical therapy fails to achieve adequate symptom control. This review summarizes the latest information on the outcomes after endoscopic sinus surgery (ESS) with relation to QoL, revision rates, olfaction, absenteeism, asthma control, use of systemic medications, quality of sleep and complications. We also provide an update regarding the factors that can impact outcomes. RECENT FINDINGS CRS has classically been divided into two phenotypes depending on the presence or absence of nasal polyps. However, this is an oversimplification as many factors impact disease burden and outcome after treatment. It has been demonstrated that in many cases, ESS fails to meet the expectations of the patients. Evidence based patient counselling is key to help surgeons guide their patients in the best possible way to make well-informed decisions. Repeatedly it has been demonstrated that ESS improves QoL, improves olfaction, leads to better asthma control and less use of systemic antibiotics. However, various patient characteristics including phenotype, disease burden, comorbidities, age, gender and surgical technique can influence the outcome after ESSIt is of paramount importance to include a follow-up period when discussing revision rates. Based on available data, the genuine revision rate is probably 15-20% after five to ten years of follow-up. The revision rate is also affected by various factors and comorbidities.

Abstract
Novel therapies such as type 2 targeting biologics are emerging treatment options for patients with chronic inflammatory respiratory diseases, fulfilling the needs of severely uncontrolled patients. The majority of patients with chronic rhinosinusitis with nasal polyps (CRSwNP) and over half of patients with asthma show a type 2 inflammatory signature in sinonasal mucosa and/or lungs. Importantly, both chronic respiratory diseases are frequent comorbidities, ensuring alleviation of both upper and lower airway pathology by systemic biological therapy. Type 2-targeting biologics such as anti-IgE, anti-IL4Rα, anti-IL5, and anti-IL5Rα have entered the market for selected pheno/endotypes of asthma patients and may soon also become available for CRSwNP patients. Given the high prevalence of chronic respiratory diseases and the high cost associated with biologics, patient selection is crucial in order to implement such therapies into chronic respiratory disease care pathways. The European Forum for Research and Education in Allergy and Airway Diseases (EUFOREA) organized a multidisciplinary Expert Board Meeting to discuss the positioning of biologics into the care pathways for CRSwNP patients with and without comorbid asthma.

Abstract
Background Chronic rhinosinusitis with nasal polyposis (CRSwNP) is a therapeutic challenge because of the high recurrence rate. Surgical intervention should be considered in patients who fail to improve after medical treatment. We monitored recurrence and revision surgery over 12 years after endoscopic sinus surgery in CRSwNP patients. Methods In this prospective cohort study, 47 patients with CRSwNP, who underwent primary or revision extended endoscopic sinus surgery, were followed. Clinical symptoms and total nasal endoscopic polyp score were evaluated before, 6 years and 12 years after surgery. Results Twelve years after surgery, 38 out of 47 patients (80.9%) were available for examination. There still was a significantly better symptom score and total nasal endoscopic polyp score compared to before surgery (P < 0.001). Within the 12-year follow-up period, 30 out of 38 patients developed recurrent nasal polyps, of which 14 patients underwent additional revision surgery. Comorbid allergic sensitization and tissue IL-5 levels were found to be significant predictors for the need of revision surgery. Conclusions This long-term cohort study, investigating the outcome after surgery in CRSwNP, showed that, despite the low number of patients, 78.9% of patients with CRSwNP were subject to recurrence of the disease and 36.8% to revision surgery over a 12-year period.

Abstract
The objective of the present study was to upgrade the rhinological simulator employed as a tool for the teaching of the basic technical skills in endoscopic sinus surgery (ESS). The new ESS simulator providing a model of the nasal cavity consists of the replaceable cylinders and the adaptable table stand. It includes a set of 3D printed nasal models. Each of them is the elliptical tube of a specific size. The participants of the study performed different tasks depending on the structural properties of the tubes. A wide variety of surgical instruments and esndoscopes could be fitted to the simulator. 16 otorhinolaryngologists having no previous experience with ESS were recruited into the study to evaluate the effectiveness of the training procedures. After a brief tutorial, the participants practiced an one hour-long exercise per day during 5 days. The pre-training and post-training performances were videotaped. The task-performance time and the number of technical errors made by the operators were estimated immediately before and after the training session. To assess the subjective attitudes of the operators toward the new technology, the participants of the study were asked to complete the model questionnaire soon after the termination of the training course. The questionnaire contained 34 items. The correctness of the answers was assessed based on the 5-point Likert scale, with score 1 meaning 'totally disagree' and score 5 - 'totally agree'. The statistically significant reduction of the performance time and the number of technical mistakes was documented within the first 5 hours after the onset of teaching (p<0.05) which suggests the effectiveness of the training procedures. The questionnaire study has demonstrated the positive attitude of the trainees toward the proposed technology. The average score based on the Likert scale was higher than 3 for all kinds of questions. It is concluded that the results of this study give evidence of the positive assessment of the upgraded rhinological simulator as an effective tool for the teaching of the basic skills necessary to operate various surgical instruments and endoscopes by the novice surgeons in the field of endoscopic sinus surgery .

Abstract
Decisions about resource allocation are increasingly based on value trade-offs between health outcomes and cost. This process relies on comprehensive and standardized definitions of health status that accurately measure the physical, mental, and social well-being of patients across disease states. These metrics, assessed through clinical trials, observational studies, and health surveys, can facilitate the integration of patient preferences into clinical practice. This ninth installment in the Evidence-Based Medicine in Otolaryngology Series is a practical overview of health outcome valuation, as well as the integration of both quality and quantity of life into standardized metrics for health research, program planning, and resource allocation. Tools for measuring preference-based health states, measures of effectiveness, and the application of metrics in economic evaluations are discussed.

Non-thermal plasma treated solution with potential as a novel therapeutic agent for nasal mucosa regeneration. Sci Rep 2018; 8:13754.

Abstract
Adequate and rapid mucosal regeneration is one of the most important factors in the healing process of nasal mucosa after surgery or trauma. In particular, delayed mucosal regeneration after surgery is an important cause of surgical failure. However, no effective treatment is available yet. Non-thermal plasma (NTP) has several medical effects, but the existing probe type is limited to local direct treatment. Therefore, we investigated the various effects using liquid type plasma to overcome this limitation. In addition, the therapeutic effects of non-thermal plasma treated solution (NTS) on nasal mucosa have yet to be determined. Experiments were carried out using BEAS-2B, a human bronchial epithelial cell line similar to nasal mucosa epithelium. NTS had no cytotoxicity to the BEAS-2B cells and enhanced cell proliferation. NTS also promoted migration of BEAS-2B cells. NTS increased cell proliferation and migration via epidermal growth factor receptor (EGFR) activities and epithelial-to-mesenchymal transition (EMT) signaling. Furthermore, NTS enhanced wound healing of nasal mucosa in an animal model. Accordingly, NTS promotes nasal mucosa wound healing by increasing cell proliferation and migration. These findings suggest the therapeutic potential of NTS in nasal mucosa wound healing.

Abstract
OBJECTIVES There is little consensus regarding the prognostic value of symptom duration in predicting clinical disease severity or quality-of-life (QOL) outcomes in patients with chronic rhinosinusitis (CRS). Our objectives were to: 1) determine if patients with longer symptom duration have worse preoperative disease severity and/or QOL, and 2) determine if delayed surgical intervention influences outcomes of endoscopic sinus surgery (ESS). METHODS Patients diagnosed with CRS were prospectively enrolled into a multicenter cohort study and observed 14.7 (standard deviaton {SD} ± 4.8) months on average following primary ESS. Preoperative symptom duration was stratified into short-term (< 12 months), middle-term (12-60 months), and long-term (> 60 months). Disease severity was assessed using endoscopy and computed tomography. Disease-specific QOL was measured with the 22-item Sinonasal Outcome Test (SNOT-22) and Rhinosinusitis Disability Index. Adjusted bivariate and multivariate associations between symptom duration, disease severity, and QOL scores were evaluated. RESULTS One hundred and thirteen patients met inclusion criteria with 35 patients lost to postoperative follow-up. No significant differences in preoperative disease severity or QOL scores were reported between symptom duration subgroups. Participants in the long-term symptom subgroup reported significantly greater mean postoperative improvement on SNOT-22 total scores (n = 28; -36.3[± 22.2]) compared to both short-term (n = 27; -23.4[SD ± 11.3]; P = 0.039) and middle-term (n = 23; -23.5[SD ± 20.1]; P = 0.050) subgroups. Postoperative QOL improvements in the long-term symptom subgroup remained significantly greater (P ≤ 0.036) after multivariate adjustment. CONCLUSIONS Symptom duration was not associated with mean preoperative disease severity or QOL. Patients with long-term symptom duration reported the greatest mean postoperative QOL improvement, suggesting that delayed surgical intervention may not reduce QOL improvements following ESS.

Abstract
BACKGROUND Previous work has shown that the symptoms of chronic rhinosinusitis (CRS) differentially associate with decreased general health-related quality of life (QOL). OBJECTIVE We sought to determine whether longitudinal changes in different types of CRS symptomatology lead to correspondingly different magnitude changes in general health-related QOL. METHODS Prospective observational study of 145 patients undergoing medical management for CRS. Chronic rhinosinusitis symptom severity was measured using the 22-item Sinonasal Outcome Test (SNOT-22) and associated nasal, sleep, ear/facial discomfort, and emotional subdomains of the SNOT-22. General health-related QOL was measured using the 5-dimensional EuroQoL questionnaire's visual analog scale (EQ-5D VAS). These data were collected at 2 time points: at enrollment and at a subsequent follow-up visit within the next 2 to 6 months. Associations were sought between the changes in SNOT-22 and EQ-5D VAS. RESULTS The change in SNOT-22 was associated with change in EQ-5D VAS (adjusted linear regression coefficient [β] = -0.37, 95%CI: -0.51 to -0.24, P < .001). The change in EQ-5D VAS was only associated with changes in the sleep (adjusted β = -0.42, 95% confidence interval [95%CI]: -0.81 to -0.04, P = .034) and ear/facial discomfort (adjusted β = -1.00, 95%CI: -1.89 to -0.10, P = .031) subdomains but not nasal (adjusted β = -0.12, 95%CI: -0.52 to 0.28, P = .564) or emotional (adjusted β = -0.17, 95%CI: -1.83 to 1.49, P = .840) subdomains. CONCLUSION Changes in the severity of sleep and ear/facial discomfort symptoms associate most greatly with the change in general health-related QOL that CRS patients experience during routine medical management. Reduction of these extranasal symptoms of CRS may therefore lead to the greatest improvement in general health-related QOL.

Abstract
BACKGROUND Misuse and diversion of prescription opioids have been critical in facilitating the opioid epidemic. Our objective was to perform a systematic evidence-based review delineating perioperative regimens (including opioid alternatives) evaluated for endoscopic sinus surgery. METHODS PubMed/MEDLINE, Cochrane Library, and EmBase databases were evaluated for studies detailing analgesics employed after endoscopic sinus surgery. Studies were assessed for level of evidence. Bias risk was evaluated using the Cochrane Bias tool and GRADE criteria. Medication, administration, adverse effects, pain scores, and rescue analgesic consumption were evaluated. A summary of evidence detailing benefits, harm, and cost was prepared. RESULTS Thirty-two studies encompassing 1812 patients were included. The GRADE criteria determined the overall evidence to be of moderate quality. Perioperative acetaminophen had few adverse events and reduced immediate need for opioid rescue after sinus surgery; studies evaluating acetaminophen demonstrate a preponderance of benefit over harm. Nonsteroidal anti-inflammatory drugs (NSAIDs) also reduce postoperative opioid consumption, although a small portion of patients undergoing sinus surgery harbor the potential for NSAID intolerance. The aggregate level of evidence for studies evaluating NSAIDs was grade A, whereas the aggregate grade of evidence for several other agents was grade B. CONCLUSION There is evidence supporting the use of NSAIDs and gabapentin for the control of pain after endoscopic sinus surgery. Acetaminophen, α-agonists, and local anesthetics are also viable options for postoperative analgesia. Familiarity with these data is essential to facilitate the use of opioid alternatives. Further large-scale, multi-institutional, randomized trials are needed to provide conclusive recommendations for these perioperative analgesics.

Abstract
Purpose of Review Chronic rhinosinusitis is a disease with high prevalence, significant impact on health-related quality of life (HRQoL) and it is associated with substantial healthcare and productivity costs. We face an urgent need to improve the level of disease control and achieve higher patient satisfaction and disease prevention. Precision medicine is increasingly recognized as the way forward in optimal patient care. The combination of personalized care, prevention of disease, prediction of success of treatment, and participation of the patient in the elaboration of the treatment plan is expected to guarantee the best possible therapeutic approach for individuals suffering from a chronic disabling condition. Recent Findings This is a narrative review on the current state of endotypes, biomarkers, and targeted treatments in chronic inflammatory conditions of the nose and paranasal sinuses. Different phenotypes of rhinitis and chronic rhinosinusitis (CRS) have been described based on symptom severity and duration, atopy status, level of control, comorbidities, and presence or absence of nasal polyps in CRS. The underlying pathophysiological mechanisms are diverse, with different endotypes being recognized. Novel emerging therapies are targeting specific pathophysiological pathways or endotypes. This endotype-driven treatment approach requires careful selection of the patient population who might benefit from a specific treatment. Summary This review provides a comprehensive overview of the current state of endotypes, biomarkers and targeted treatments in chronic inflammatory conditions of the nose and paranasal sinuses.
